Dracodrill, Velozolt, Dunklevish, & Arctoness
All four are based on the 'Fusion Fossils' made during the Bone Wars. Scientists often put mixed up dinosaurs fossils together, hoping they would look normal. This led to some inconsistencies in fossils, like putting their heads on tails or making up completely new dinosaurs.

= Legendary Pokemon = Legendary Pokémon (のポケモン Densetsu no Pokemon), or Pokémon Illusions (のポケモン Phantom Pokémon) are extremely rare, often powerful Pokémon that are often associated with legends of creation and/or destruction within their endemic regions.

Due to their power, Legendary Pokémon are often the target of Villain Groups that seek to control or change the world within both the anime and the games; in the latter, thwarting such attempts has been integrated into each game's plot since Generation III.

Generation I
The first generation Legendary Pokémon (のポケモンの Densetsu no Pokemon no Dai Ichi-sedai) are the first legendary Pokémon introduced in the Pokémon series. These Pokémon first appeared in the Kanto region and as such are often associated with the area.

Kanto introduced four Legendary Pokémon: Articuno, Zapdos, Moltres, and Mewtwo.

Legendary Birds
The Legendary Birds (の Densetsu no Tori) are a trio of Legendary Pokémon that resemble birds, consisting of the Ice/Flying-type Articuno (フリーザー Furiizaa), the Electric/Flying-type Zapdos (サンダー Sandaa), and the Fire/Flying-type Moltres (ファイヤー Faiyaa). The Legendary Birds also have Regional variants that are seen in the Galar region. Galarian Articuno has the Psychic/Flying type, Galarian Zapdos has the Fighting/Flying type, and Galrian Moltres has the Dark/Flying type.

Articuno first appeared in the games Pokémon Red, Green, and, outside of Japan, Blue Versions hidden within the Seafoam Islands. Zapdos could be found at the Kanto Power Plant, while Moltres could be captured in Victory Road. Pokémon Yellow featured the trio in their previous locations, while later games featuring Kanto moved Moltres to different areas: in FireRed and LeafGreen, the Flame Pokémon was at Mt. Ember; in Mt. Silver in HeartGold and SoulSilver. Pokémon Platinum featured the Legendary Birds as roaming Sinnoh after the player character defeats the Pokémon League. In Pokémon XD: Gale of Darkness, the three legendary birds appear as Shadow Pokémon and are originally used by Grand Master Greevil. In Pokémon X and Y, one of the birds may be found roaming Kalos after defeating the Pokémon League, with the Pokémon depending on the player character's starter. If the player character chooses Chespin, they will encounter Articuno; if they have Fennekin, they will see Zapdos; and if they picked Froakie, they may catch Moltres. The bird must be encountered 11 times, however, before they will retreat to the Sea Spirit's Den and become available for capture. In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, the trio are featured in their previous locations from Red, Blue, and Yellow.

In the anime, all three Legendary Pokémon appear in the film The Power of One, where they reside at Shamouti Island. Local legend claimed that if the three began fighting, only Lugia could calm the birds. Each Legendary has also been shown in the anime episodes, which are listed chronologically below.

In a similar vein to several other Legendary Pokémon, the Legendary Birds are part of a trio, with Lugia serving as a trio master.

Their names come from their controlling element and the numbers one, two, and three in Spanish: "Arctic", referring to the geological area, and "uno", one; "Zap", a strike associated with electricity, and "dos", two; and "Molt", from molten and "tres", three.

In the manga Pokémon Adventures, Articuno, Zapdos, and Moltres are fused into one Pokémon known as Zapmolcuno.

Mewtwo
Mewtwo (ミュウツー Mewtwo) it's a man-made Pokémon created by scientists in the Pokémon Mansion and is a Psychic-type.

Mewtwo originally appeared in Pokémon Red, Green, and Blue as a hidden Pokémon. It could be found within Cerulean Cave after beating the Elite Four and becoming the Kanto region champion.

In the anime, Mewtwo serves as the titular Pokémon in Mewtwo Strikes Back and Mewtwo Returns; in the former, it is revealed that Mewtwo is a genetically-enhanced clone of Mew commissioned by Giovanni. After being controlled by Giovanni, Mewtwo sets out to control the world with its own clone Pokémon.

In Generation VI, Mewtwo was given two Mega Evolutions, Mewtwo X and Mewtwo Y, which feature different stats and abilities. The stones necessary to cause the evolution are Mewtwonite X, which evolves Mewtwo into Mewtwo X, a Psychic/Fighting-type, and Mewtwonite Y, which evolves Mewtwo into Mewtwo Y, which remains Psychic. The stones could originally be found in Pokémon X and Y, respectively; both can be located in Pokémon Omega Ruby and Alpha Sapphire. In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, these stones can be obtained after going to Cerulean Cave a second time, after catching Mewtwo, and then, defeating Green.

Generation II
The second generation Legendary Pokémon (のポケモンの Densetsu no Pokemon no Dai Ni-sedai) are the second set of Legendary Pokémon introduced in the Pokémon series and originate within the Johto region.

Five Legendary Pokémon debuted in Generation II: Raikou, Entei, Suicune, Ho-Oh, and Lugia.

Legendary Beasts
The Legendary Beasts (の Densetsu no Kemono) consist of the Electric-type Raikou (ライコウ Raikou), the Fire-type Entei (エンテイ Entei), and the Water-type Suicune (スイクン Suikun).

The three Legendaries were originally unidentified Pokémon trapped and killed within the Brass Tower when it burned down due to lightning. Ho-Oh revived the trio with each Pokémon acquiring an attribute of the accident: Raikou, an Electric-type, symbolized the lightning that had struck the tower; Entei, a Fire-type, was the flames that had engulfed the tower; and Suicune, a Water-type, represented the rain that put out the blaze. Those that witnessed the accident and revival of the trio feared their power, causing the beasts to flee. As a result, they are the first roaming Pokémon the player character encounters.

In Pokémon Gold and Silver, the trio will individually wander the Johto region after the player character first encounters them in the Brass Tower. In Pokémon Crystal, the player character is also required to force Team Rocket to vacate the Radio Tower and acquire the Clear Bell to meet Suicune in the Tin Tower. In Pokémon Colosseum the trio was captured by Cipher and transformed into Shadow Pokémon; each are owned by different Admins. In Pokémon FireRed and LeafGreen, one member may be found roaming Kanto after defeating the Pokémon League; if the player character chose Bulbasaur they may find Entei; if the starter Pokémon is Charmander, then Suicune is roaming; if the player character has Squirtle, then Raikou can be found. The encounters in Pokémon HeartGold and SoulSilver the circumstances are similar to those in Crystal; however, Suicune must be followed throughout the Kanto region until it stops at Route 25, outside Bill's house, where it may be battled. Notably, Eusine chases Suicune throughout the game but is constantly eluded.

All three members of the trio have appeared as a major character of separate movies and in episodes of the anime. An Unown-produced Entei served as an antagonist-turned-protagonist in Spell of the Unown, while a Suicune helped heal a Celebi by purifying a lake's water in Celebi: Voice of the Forest. Shiny versions of each member also appeared in Zoroark: Master of Illusions, where they attempted to defeat a Zoroark.

Not listed here is Raikou's appearance in the Pokémon Chronicles episode Legend of Thunder!, where it was being hunted by members of Team Rocket.

Tower Duo
The Tower Duo (タワーデュオ Tawā Duo) is the two bird-like Pokémon the Fire/Flying-type Ho-Oh (ホウオウ Houou) and the Psychic/Flying-type Lugia (ルギア Rugia).

Known as the "guardian of the skies" and "guardian of the seas", respectively, Ho-Oh and Lugia formerly resided in Ecruteak City, claiming the Tin Tower and Brass Tower. When lightning struck the Brass Tower and burned the building, Lugia escaped to the Whirlpool Islands. Ho-Oh remained long enough to revive three Pokémon that had been trapped within the tower, creating the Legendary Beasts, but left in search of a pure-hearted Trainer; thus, Ho-Oh is considered their trio master.

Both Pokémon appear in the Pokémon Gold and Silver Versions; their method of encounter varies between the games. In Gold, the player character may capture Ho-Oh, a Fire/Flying-type, at the Tin Tower once acquiring a Rainbow Wing after Team Rocket leaves the Goldenrod Radio Tower and locate Lugia, a Psychic/Flying-type, at the Whirlpool Islands once given a Silver Wing from a citizen in Pewter City. In Pokémon Silver, this is reversed: the player character is given the Silver Wing once Team Rocket leaves the Radio Tower and the Rainbow Wing in Pewter City. In Pokémon Crystal, the player character must capture Raikou, Entei, and Suicune to gain the Rainbow Wing, and visit the Pewter City resident to gain the Silver Wing. Both Pokémon reappear in FireRed and LeafGreen, as well as Pokémon Emerald, but must be gained through an event; they may be found at Naval Rock if the player character has a MysticTicket. Ho-Oh can be caught in Pokémon Colosseum if the player character purifies all Shadow Pokémon in the game, while Lugia can be caught as a Shadow Pokémon in Pokémon XD: Gale of Darkness. Contrary to initial belief, this Lugia is capable of being purified. Ho-Oh and Lugia return again in HeartGold and SoulSilver and may be acquired under similar circumstances, though the player character must also have a Clear Bell and Tidal Bell for each Legendary.

Both Pokémon have appeared within the anime, though only Lugia has made an appearance in a film, The Power of One. In the film, Lugia was the only creature capable of quelling the three Legendary Birds, Articuno, Zapdos, and Moltres, making Lugia their trio master. Ho-Oh, however, was the first Legendary Pokémon to appear in the anime, debuting at the end of the first episode of the series. At the time Ho-Oh had not been officially announced nor was it identified in the episode, being endemic to Johto.

The episodes that each Ho-Oh and Lugia have appeared in are listed below.

Generation III
The third generation Legendary Pokémon (のポケモンの Densetsu no Pokemon no Dai San-sedai) are the third set of Legendary Pokémon introduced in the series and are native to the Hoenn region.

There are eight Legendary Pokémon introduced in Hoenn: Regirock, Regice, Registeel, Latios, Latias, Kyogre, Groudon, and Rayquaza.

Hoenn Legendary Titans
The Hoenn Legendary Titans (のタイタンズ Densetsu no taitanzu), also known as the Regi Trio (ゴーレムトリオ Gōremu Torio), consists of three Legendary golem-like Pokémon: Regirock, a Rock-type, Regice, an Ice-type, Registeel, a Steel-type. According to legend, they were shaped by their trio master, Regigigas. As their names and typing suggest, Regirock was formed from rocks, Regice from ice, and Registeel from steel.

The trio makes their first appearance in Pokémon Ruby and Sapphire, as well as in Emerald. Finding the golems is similar in each game: the player character must first travel to the underwater Sealed Chamber, found by diving in Route 134 with a Relicanth and Wailord in their team. Upon completion of the task, each golem will be unlocked and may be found throughout Hoenn. Specifically, Regirock is within the Desert Ruins of Route 111, Regice is in the Island Cave on Route 105, and Registeel inside the Ancient Tomb, in Route 120. Each comes with their own specific tasks and requirements: in Ruby and Sapphire, to gain Regirock, the player character must read the inscription then move right twice, down twice, and use Strength; to find Regice, the player character must read the inscription and wait two minutes without interacting with the game; to fight Registeel, the player character must read the inscription, then use Fly in the center of the room. In Pokémon Emerald, the player character must instead use Rock Smash, run around the chamber while staying next to the walls, and use Flash for Regirock, Regice, and Registeel, respectively. In Pokémon Platinum, Regirock may be found at the Rock Peak Ruins, Regice at the Iceberg Ruins, and Registeel within the Iron Ruins; however, they are event-only. In Pokémon Omega Ruby and Alpha Sapphire, the method of acquiring the golem trio is the same as it is in Ruby and Sapphire. The trio, along with Regieleki and Regidrago, can be found in temples of the same names as Sinnoh's within the Crown Tundra included in Pokémon Sword and Shield Expansion Pass.

All three of the trio have appeared in Lucario and the Mystery of Mew, as guardians of the Tree of Beginning. A Regirock, Regice, and Registeel also belonged to Pyramid King Brandon in the anime.

Eon Duo
The Eon Duo (イオンデュオ Ion Duo) is formed by the twin Pokémon Latios and Latias.

Both Pokémon are Dragon/Psychic-type, identified as the "Eon Pokémon"; in all instances, Latios are male and Latias are female. The duo is said to be a brother-sister duo. Both are roaming Pokémon in their first appearance, with Latios appearing in Pokémon Ruby and Latias appearing in Pokémon Sapphire. In Emerald, the player character selects which Pokémon will roam Hoenn after defeating the Pokémon League. In all three games, if the player character has the Eon Ticket, they may encounter the other Pokémon on Southern Island. Both reappear in HeartGold and SoulSilver as roaming Pokémon, with Latias appearing in HeartGold and Latios in SoulSilver; they will only roam the Kanto region in these games. Once the player character has defeated the Pokémon League and obtained the National Pokédex, they may use bring the event-only item, the Enigma Stone, to Steven Stone in Pewter City. He will identify it as a Soul Dew and the Eon Pokémon that does not roam the Kanto region will attack the player character. Should they fail to capture the Pokémon, it will continue returning to the same spot it was encountered.

As of Pokémon Omega Ruby and Alpha Sapphire, both Pokémon are capable of Mega Evolving using Latiosite or Latiasite. In addition to aesthetic changes, each Pokémon's stats and abilities change upon evolution.

Both Pokémon appear in the film Heroes: Latios and Latias as guardians of Alto Mare. The film focuses on the Soul Dew, which the film confirms as a Latios'/Latias' crystallized soul. Tobias used a Latios during the Lily of the Valley Conference.

Weather Trio
The Weather Trio (トリオ Tenki Torio), also known as the Ancient Trio (トリオ Kodai Torio), is composed of the Water-type Kyogre (カイオーガ Kaiooga), the Ground-type Groudon (グラードン Guraadon), and the Dragon/Flying-type Rayquaza (レックウザ Rekkuuza).

Hoenn's legends claim that Kyogre could call upon rain and created the sea, while Groudon used heat to repel rain and expand the continents, creating land. These two Pokémon clashed whenever they met and could only be stopped by Rayquaza, who lived in the atmosphere. As such, Rayquaza is considered the trio master.

In their original appearances, Groudon could only be caught in Ruby and Kyogre in Sapphire, with both being found at the Cave of Origin. Rayquaza could be caught in all three games, at Sky Pillar; in Ruby and Sapphire, it could be found after defeating the Elite Four, while in Emerald it was battled prior to fighting the Pokémon League. In Pokémon HeartGold and SoulSilver, the player character could use the Blue Orb (HeartGold) or Red Orb (SoulSilver) at the Embedded Tower to call either Kyogre or Groudon and battle them. If the player character had a Kyogre and Groudon native to HeartGold or SoulSilver and brought them to Professor Oak, he would give the player character the Jade Orb, which could be used to summon Rayquaza in the same manner. Groudon and Kyogre make similar appearances in Omega Ruby and Alpha Sapphire; however, when the player character battles them, they have undergone Primal Reversion and have signature moves, Precipice Blades and Origin Pulse, respectively. Rayquaza has also gained a Mega Evolution and its own signature move, Dragon Ascent, which is necessary for Mega Evolution in lieu of a Mega Stone.

All three Pokémon have appeared in the anime and in movies. A fake Groudon was shown in Jirachi: Wish Maker, a Rayquaza played the role of the antagonist in Destiny Deoxys, and a Kyogre made a minor appearance in MS009: Pokémon Movie - Pokémon Ranger and the Temple of the Sea.

The episodes that each Pokémon has appeared in is listed below.

Generation IV
The fourth generation Legendary Pokémon (のポケモンの Densetsu no Pokemon no Dai Yon-sedai) are the fourth series of Legendary Pokémon introduced in the Pokémon series. These Pokémon originate from and originally appear in the Sinnoh region.

There are nine Legendary Pokémon that appear in Generation IV: Uxie, Mesprit, Azelf, Dialga, Palkia, Heatran, Regigigas, Giratina, and Cresselia.

Lake Guardians
The Lake Guardians (レイクトリオ Reiku Torio), is named for the tendency of its members, Uxie (ユクシー Yukushii), Mesprit (エムリット Emuritto), and Azelf (アグノム Agunomu), to remain in the vicinity of their respective lakes within the Sinnoh region.

All three members are purely Psychic-type, and all three were created by Arceus to protect and embody certain concepts, and later, taught humans these traits. Uxie, who remains at Lake Acuity, represents knowledge, Mesprit, who is close to Lake Verity, symbolizes emotion, and Azelf, who is tied to Lake Valor, is spirit or willpower. Thus, Arceus is considered the master of Lake Guardians.

The Lake Guardians originally appear in Pokémon Diamond and Pearl, where they are captured by Team Galactic's commanders so Cyrus may use their powers to create a Red Chain, which will allow him to take control of either Dialga or Palkia, in Diamond and Pearl respectively. In Platinum, he intends on chaining both Pokémon; in this case, the Lake Guardians appear before Cyrus to stop him but are too weak, causing Giratina to open the Distortion World.

The three lake guardians play a major role in the Generation IV video game series. In the Pokémon Diamond, Pearl, and Platinum game series Team Galactic's commanders captured the lake guardians for their leader Cyrus and he uses their powers to craft a Red Chain in order to take control of Dialga in Pokémon Diamond and Palkia in Pokémon Pearl and both of them in Pokémon Platinum and recreate the universe without spirit.

In all Generation IV games, the Lake Trio will reappear at their individual lakes. Uxie and Azelf may be captured upon encountering them, but Mesprit will flee from the player character and begin roaming Sinnoh.

Though none of the Lake Trio have appeared in any films, they have all appeared within the anime series, alone and together. The episodes they have appeared in are listed below.

Creation Trio
The Creation Trio (クリエイション·トリオ Kurieishon Torio), also known as the Crown Dragon Trio (クラウンドラゴン·トリオ Kuraun Doragon Torio) consists of the Steel/Dragon-type Dialga (ディアルガ Diaruga), the Water/Dragon-type Palkia (パルキア Parukia), and the Ghost/Dragon-type Giratina (ギラティナ Giratina).

According to Sinnoh legend, when the universe began, Arceus created Pokémon to craft the universe. When Dialga was born, time began; space expanded when Palkia came to be, and Giratina was formed to control antimatter. As such, Arceus is considered the trio master of the Creation Trio.

In Pokémon Diamond and Pearl, Cyrus plans on summoning and controlling either Dialga or Palkia at Spear Pillar so he may recreate the universe; the player character may interrupt and capture the Pokémon instead. In Platinum, he attempts to summon both but is interrupted by Giratina, who takes Cyrus into the Distortion World for intending to enslave the other members of its trio. The player character may enter the Distortion World and capture Giratina after defeating the Pokémon League.

In the video games, Cyrus tries to take control of Dialga and Palkia which depends on the Diamond or Pearl series, it contains both at the same time in Pokémon Platinum in order to remake the universe without spirit, a thing that Cyrus despises. Dialga or Palkia can be captured at Spear Pillar which depends on the video game. In Pokémon Platinum, Giratina takes Cyrus into the Distortion World after that he was trying to take control of Dialga and Palkia. Giratina can be captured in the Distortion World but Dialga and Palkia can be captured after defeating the Pokémon League, at the Spear Pillar.

All three Pokémon appear in one or more films, and in the anime. Dialga appeared in The Rise of Darkrai, Giratina and the Sky Warrior, and MS012: Pokémon - Arceus and the Jewel of Life. Palkia appeared in MS010 and MS012, while Giratina was shown in MS011 and MS012. All three Pokémon appeared in the same episode of the anime.

Cresselia
Cresselia (クレセリア Crecelia) is a Pokémon that resembles the Full Moon and dreams, it's the counterpart of the Mythical Pokémon Darkrai.

Cresselia, the Psychic-type "Lunar Pokémon" was first encountered on Fullmoon Island; this is more or less coincidence, as while Cresselia is symbolic of the full moon.

In Pokémon Diamond, Pearl and Platinum, Cresselia may be found on Fullmoon Island after defeating the Elite Four. The player character must secure a Lunar Wing for Eldrich's son, who is suffering from endless nightmares. The player character may then travel to the island where they will see Cresselia; the Legendary disappears but leaves a Lunar Wing behind. It may then be found roaming Sinnoh.

Cresselia appears along with Darkrai in the anime episode Sleepless in Pre-Battle. In addition.

Heatran
Heatran (ヒードラン Hīdoran) is a Fire/Steel-type Pokémon, rumored to be the spirit and protector of all volcanic activity.

It is believed to have been created when Dialga, Palkia, and Giratina were brought into being; despite this, it is not included in the trio. Uniquely, Heatran is the only Legendary that may be either male or female, with a 50% chance of either gender appearing in a wild encounter.

Heatran makes its first appearance in Diamond and Pearl, where it may be found on Stark Mountain after defeating the Pokémon League, visiting Stark Mountain and after the player character talks to Buck's grandfather; Buck will have taken the Magma Stone but returns it after speaking to his grandfather. Once the stone is returned, Heatran will appear on the mountain. In Platinum, Charon, a former member of Team Galactic, plans to steal the Magma Stone and use it to control Heatran, allowing him to extort citizens for money by threatening them with the Pokémon's volcanic powers. His scheme is thwarted by interference from Buck, Looker, and the player character, at which point Heatran may be captured. In Pokémon Black 2 and White 2, if the player character has retrieved the Magma Stone from Route 18 and brings it to Reversal Mountain, they may meet Heatran. In Omega Ruby and Alpha Sapphire, after Groudon/Kyogre has been captured or defeated, the player character may journey to the Scorched Slab to capture a Heatran residing on the lowest floor.

Heatran appears in both the anime and in the film Arceus and the Jewel of Life.

Regigigas
Regigigas (レジギガス Rejigigasu) is a legendary Normal-type.

Along with having the distinction of being the only Normal-type Legendary Pokémon to date, Regigigas is credited with the creation of Regirock, Regice, and Registeel. In addition, legends state that Regigigas "towed" the continents into their current positions. As such, Regigigas is the trio master of the Golem Trio.

In Diamond, Pearl and Platinum, Regigigas may be found in Snowpoint Temple after the Pokémon League has been defeated, but in order to capture it, the player character must have all three golem Pokémon in their party. It also appears in Black 2 and White 2 at Twist Mountain with similar requirements: that the League be defeated and having Regirock, Regice, and Registeel in their party. In Omega Ruby and Alpha Sapphire, the player character may find Regigigas at the Island Cave where they caught Regice, but they must visit during the daytime with all three golem Pokémon in their team. In addition, their Regice must be nicknamed and holding a Casteliacone, a Never-Melt Ice, an Icy Rock, or a Snowball.

Regigigas makes an appearance in the anime and in the film Giratina and the Sky Warrior.

Generation V
The fifth generation Legendary Pokémon (のポケモンの Densetsu no Pokemon no Dai Go-sedai) are the fifth generation of Legendary Pokémon introduced in the Pokémon series. These Pokémon originate and appear in the Unova region.

Nine Legendary Pokémon appear in Generation V: Cobalion, Terrakion, Virizion, Tornadus, Thundurus, Reshiram, Zekrom, Landorus, and Kyurem.

Swords of Justice
The Swords of Justice consists of the Steel/Fighting-type Cobalion (コバルオン Kobaruon), the Rock/Fighting-type Terrakion (テラキオン Terakion), the Grass/Fighting-type Virizion (ビリジオン Birijion), and the Water/Fighting-type Keldeo (ケルディオ Kerudio). They exist to protect Pokémon that have lost their homes to humans. Keldeo is the only Mythical Pokémon of the group.

Cobalion, Terrakion, Virizion, and Keldeo are all Fighting-type with a secondary type in conjunction with their names, i.e. "Cobalt" in Cobalion for Steel-type, "Terra" in Terrakion for Ground-type, "Viridian" in Virizion for Grass-type. and "Kelpie" in Keldeo for Water-type. Only Keldeo has an alternate Forme, its Resolute Form if it knows Secret Sword.

The Swords of Justice are the first Legendary Quartet.

They all made their debut in the film Kyurem vs. the Sword of Justice.

Forces of Nature
The Forces of Nature (の Shizen no Chikara) consists of the Flying-type Tornadus (トルネロス Torunerosu), the Electric/Flying-type Thundurus (ボルトロス Borutorosu), and the Ground/Flying-type Landorus (ランドロス Randorosu).

Tornadus represents wind, Thundurus represents lightning, and Landorus represents ground. Interestingly, Tornadus is the first and as of yet only Pokémon that is a pure Flying-type.

By using the Reveal Glass, the player character may change each member from their Incarnate Forme into their Therian Forme, which are vaguely human and animal, respectively. The Forces of Nature is the only trio of Legendaries to share the same gender, being all-male, other than genderless.

Landorus is the trio master of the Forces of Nature.

Tao Trio
The Tao Trio (タオトリオ Tao Torio), also known as the Energy Trio (エネルギートリオ Enerugī Torio), is formed by the Dragon/Fire-type Reshiram (レシラム Reshiramu), the Dragon/Electric-type Zekrom (ゼクロム Zekuromu), and the Dragon/Ice-type Kyurem (キュレム Kyuremu).

Each dragon is symbolic of a specific energy in Taoism, hence the name; Reshiram is symbolic of Yang and controls fire, Zekrom represents Yin and controls electricity while Kyurem is Wuji and controls ice. The three Pokémon were originally one unidentified dragon until their masters, who were twin heroes, began to argue. The older sought the truth and the younger was idealistic and, the dragon, being unable to concede to one side or the other, split into two in response, becoming Reshiram and Zekrom. Kyurem, then, was created by what remained of the original dragon, although a legend in Lacunosa Town claims it fell to the planet in an icy meteor; its ability to fuse with either Reshiram or Zekrom in Black 2 and White 2 with the DNA Splicers and become either White-Kyurem or Black-Kyurem supports the first legend, however.

Each member appeared as a major character in the franchise's films. Reshiram and Zekrom appeared in the films Black: Victini and Reshiram and White: Victini and Zekrom, where Reshiram and Zekrom switched roles between the Black and White versions of the films. Kyurem acted as the main antagonist in Kyurem vs. the Sword of Justice.

Generation VI
The sixth generation Legendary Pokémon (のポケモンのDensetsu no Pokemon no Dai Roku-sedai) Six generation of Legendary Pokémon introduced in the Pokémon series. These Pokémon originally appeared in the Kalos region.

Three Legendary Pokémon have appeared to date: Xerneas, Yveltal, and Zygarde.

Aura Trio
Xerneas, Yveltal and Zygarde form the Aura Trio (オーラトリオ Ōratorio).

The Fairy-type Xerneas (ゼルネアス Zeruneasu) and the Dark/Flying-type Yveltal (イベルタル Iberutaru) are symbolic of life and death: upon Xerneas' death, it forms a tree and gives life to its surroundings before falling into a 1,000-year slumber, while Yveltal takes the lives of everything around it before falling asleep in a cocoon form.

In Pokémon X and Y, Team Flare attempts to harness the dormant cocoon for its inherent energy and power the Ultimate Weapon; the player character intervenes and captures the Legendary before it can be utilized. Interestingly, Xerneas, Yveltal, and Rayquaza in Omega Ruby and Alpha Sapphire have the highest base catch rates due to their individual plotlines requiring the capture of the Pokémon in question.

Both Pokémon appeared in the film Diancie and the Cocoon of Destruction.

The Dragon/Ground-type Zygarde (ジガルデ Jigarude) has been described as the "guardian of the ecosystem". It monitors the ecosystem and will take action when it senses a threat to it. It does whatever is necessary to protect the ecosystem and will not hesitate to destroy any threat even if the threat is another living being.

It is the only Pokémon to have forms that are not or are questionably Pokémon, as its "Zygarde Cells", being simple and incapable of using moves, are not considered Pokémon. Zygarde Cores are Zygarde without any cells and are also unable to use attacks. If enough Zygarde Cells and come together, Zygarde can achieve its 10% Forme, 50% Forme, or its Complete Forme, which is only used if the ecosystem is under threat and Zygarde believes that it will be otherwise outmatched. Zygarde Complete Forme bears power that exceeds Xerneas and Yveltal.

Zygarde also monitors the balance between Xerneas and Yveltal and will take action when that balance is threatened.

A Zygarde named Squishy played a central role in Pokémon the Series: XYZ.

Generation VII
The seventh-generation Legendary Pokémon are the seventh generation of Legendary Pokémon introduced in the Pokémon series. These Pokémon originally appeared in the Alola region.

Alola introduced 11 new legendaries: Type: Null, Silvally, Tapu Koko, Tapu Lele, Tapu Bulu, Tapu Fini, Cosmog, Cosmoem, Solgaleo, Lunala, and Necrozma.

Six of the eleven are the first Legendary Pokémon to have evolution families.

Beast Killers
Normal-type Type: Null and Silvally are man-made Pokémon created by the Aether Foundation in a project led by Faba in order to create a Pokémon powerful enough to fight against the Ultra Beasts, after Lusamine approved the experiment, the Aether Foundation started to search data about the Mythical Pokémon Arceus in Canalave Library, they started to research for the DNA of each Pokémon type creating the RKS System and tried to straighten it in their creation, Type: Full. However, the Pokémon refused the RKS System and the project failed, so, the three Type: Full models were put control masks to control their power, were frozen, and were renamed as Type: Null.

Several years after the failure of the Beast Killer project, Lusamine's son, Gladion, ran away from the Aether Paradise with one of the three models of Type: Null and later, it was able to free itself from its mask, activating the RKS System and revelating its true form; Gladion renamed its new form as Silvally.

Guardian Deities
The Guardian Deities ( Mamorigami) Guardian Deities ( Mamorigami) are legendary Pokémon that protect the Islands of the Alola region: They also choose the kahuna from your island and gift person who they like, they sometimes give Z-Rings or Z-Power Rings for people like Kahunas or as a gift. A long time ago, legends say that the Guardian Deities fought against the Ultra Beasts that invaded the Alola Region.
 * Tapu Koko (カプ · コケコ Kapu Kokeko), an Electric/Fairy-type, from Melemele Island.
 * Tapu Lele (カプ・テテフ Kapu Tetefu), a Psychic/Fairy-type, form Akala Island.
 * Tapu Bulu (カプ・ブルル Kapu Bururu), a Grass/Fairy-type, from Ula'ula Island.
 * Tapu Fini (カプ・レヒレ Kapu Rehire), a Water/Fairy-type, from Poni Island.

The Psychic/Steel-type Solgaleo (ソルガレオ Sorugareo) and the Psychic/Ghost-type Lunala (ルナアーラ Runaa'ara) are symbolic of the sun and the moon, being seen as emissaries of those celestial bodies; Solgaleo is called "the beast that devours the sun" while Lunala is known as "the beast that calls the moon." They are both said to come from another world.

It was revealed that the duo has an evolutionary line, starting with Cosmog (コスモッグ Kosumoggu), evolving into Cosmoem (コスモウム Kosumoumu), and lastly into Solgaleo/Lunala depending on the version.

In Pokémon Sun and Moon, Lillie's Cosmog evolves into Cosmoem then evolves into either Solgaleo or Lunala at the Altar of the Sunne/Altar of the Moone when she and the player character sound the Sun and Moon flutes together. Solgaleo/Lunala then warp the two to Ultra Deep Sea to help them save Lusamine.

Cosmog, Cosmoem, Solgaleo, and Lunala are Ultra Beasts and their homeland is the Ultra Space.

Along with Necrozma, Solgaleo and Lunala are also members of the Light Trio.

Necrozma
Legends say that the Psychic-type Necrozma (ネクロズマ Nekurozuma) is known as the Pokémon that steals light, long ago Necrozma was a being of light formed and shared its light with other worlds including the world Pokémon, who was the one who gifted Alola with the Z- Crystals and Z-Power Rings, however, ancestors of the people of Ultra Megalopolis tried to take advantage of the power of Necrozma and the result was catastrophic, Necrozma eventually lost its light and acquired a form of a black prism, and hatred for the people of Ultra Megalopolis stole the light of this world and condemned it to eternal darkness.

Necrozma has three alternative forms, Dusk Mane Necrozma when it absorbs Solgaleo, Dawn Wings Necrozma when it absorbs Lunala, and finally, Ultra Necrozma, its original form that is activated when it absorbs all the energy of Solgaleo or Lunala when it's fused with one of them, after this, the Prism Pokémon activate the Ultra Burst, transforming into Ultra Necrozma.

Generation VIII
Eighth generation of Legendary Pokémon introduced in the Pokémon series. These Pokémon originally appeared in the Galar region. Eight Legendary Pokémon were introduced in Generation VIII: Zacian, Zamazenta, Eternatus, Kubfu, Urshifu, Glastrier, Spectrier, Calyrex, two other Regi Pokémon (Regieleki and Regidrago), and the Galarian counterparts of Legendary Birds.

Zacian and Zamazenta
The Fairy-type and the Fighting Warrior Pokémon, Zacian and Zamazenta, were considered heroes of the ancient Galar region after they saved it from a cataclysmic event named as "The Darkest Day", when several Wild Pokémon were surrounded by the power of Eternatus, turning into their Dynamax form and causing the chaos in Galar. However, after they fall on a deep sleep for still unknown reasons, the people of Galar, believing the heroes were dead, built a memorial at the Slumbering Weald, sealing their sacred weapons in the graves and there they stayed for centuries, being forgotten through the story.

Without their weapons, both assume the "Hero of Many Battles" form, in this state, their base stats don't differ from each other.

When holding their weapons - Zacian, with the Rusted Sword, and Zamazenta, with the Rusted Shield - they revert to their original forms, known as "Crowned Sword" for Zacian and "Crowned Shield" for Zamazenta. In these forms, both gain the Steel type.

Eternatus
The Poison/Dragon-type Legendary Pokémon Eternatus, is an extraterrestrial Pokémon that crash-landed 20,000 years ago. In ancient times, it threatened to destroy the Galar region in an event known as the Darkest Day. Chairman Rose tried to revive this Pokémon but was thwarted by the player character.

Kubfu and Urshifu
The Fighting-type Legendary Pokémon of the Isle of Armor, Kubfu, and its evolution, Urshifu, are the most notorious martial artist Pokémon line amongst Fighting Pokémon. Having been residing at mountainous areas far far away from Galar and had been inhabiting the same region long time ago, they usually went training constantly.

If Kubfu evolve into Urshifu, it grants two different secondary-types based one of two different philosophies it learned: Urshifu also has Gigantamax forms depending on the style.
 * Single Strike Style: A Dark type, represents Yang. Heavily focus on power and brutal attacks with just single strikes. Its fighting style is visible bajiquan (tiger style).
 * Rapid Strike Style: A Water type, represents Yin. Heavily focus on defense, and speedy attacks, allowing it to enhance its speed to counter opponents' predicted attacks. Its fighting style appears to be crane or mantis style.

Galar Legendary Titans
Galar introduces another two Regi Pokémon, Electric-type Regieleki, and Dragon-type Regidrago, bringing the amount of Regi Pokémon to five along with Hoenn Regi Pokémon. Like the Hoenn Regis, they are also created by Regigigas, and their name suggests which energy they are made from. The two Regis have very powerful levels of the energy they are made from, to the extent that ancient people had to seal their power in some way.

In The Crown Tundra, both of them are located in the Split-Decision Ruins. The player can only choose to challenge one of them; if the player chooses to challenge Regieleki, Regidrago becomes unavailable, and vice versa.

Glastrier and Spectrier
The two Legendary Horse Pokémon, Ice-type Glastrier and Ghost-type Spectrier are the trusty steeds of Calyrex in the Crown Tundra of the Galar region. According to Calyrex, they like to eat crops, and both of them have favorite kind of Carrots that they love to eat the most: Glastier likes Iceroot Carrots while Spectier likes Shaderoot Carrots. However, when Calyrex begins to lose its power from lack of faith, it abandoned the King Pokémon and was forgotten as well. The horses were then reunited with Calyrex thanks to the help of the player in The Crown Tundra story. When either Glastrier or Spectier are fuse with Calyrex, their primary type replace Calyrex's Grass type as its secondary type.

Calyrex
The Psychic/Grass-type Calyrex was the first ruler Pokémon in history. It was a king of Galar back in ancient times. A very noble and intelligent Pokémon who can envision the three outcomes: past, present, future. It resides at the Crown Tundra.

Calyrex is able to fuse with Glastrier or Spectrier to form Ice Rider Calyrex or Shadow Rider Calyrex, using the Reins of Unity.

Disputed Legendary
Several Pokémon are often disputed as to whether or not they are truly Legendary or are often mistaken as true Legendaries.

List

 * Arcanine - Arcanine is commonly misconstrued as a Legendary Pokémon, mainly because of an episode (named "Pokémon Emergency!", and known to be the second episode of the show) which showed Arcanine as one of the four Legendary Pokémon on the tablet at the Viridian City Pokémon Center, and because its species description since Generation I has been listed as the "Legendary Pokémon". Despite this, it is not a true Legendary.
 * Black Fog - The giant, more cryptic looking version of Haunter which has appeared in several media but never in the games. In The Electric Tale of Pikachu, it is considered a Legendary Pokémon.
 * Legendary Water Pokémon - A Legendary Pokémon which appears in Misty's dream of the future in "GS128: Enlighten Up!". It resembles the fin on Gyarados when it undergoes Mega Evolution.
 * Unown - Unown is believed by many to be a Legendary Pokémon because it is shown in Molly Hale's book about Legendary Pokémon in Spell of the Unown, its power in large number appears to match that of Legendary Pokémon and within the canon of the movie is explicitly referred to as a Legendary Pokémon.
 * Delibird - The DP Pokédex Book incorrectly states that Delibird is a Legendary Pokémon. Similar to Spiritomb, Rotom, and Spinda, this is just an error out of many in the DP Pokédex Book.
 * Spinda - The DP Pokédex Book incorrectly states that Spinda is a Legendary Pokémon. Similar to Spiritomb, Rotom, and Delibird, this is just an error out of many in the DP Pokédex Book.
 * Riolu & Lucario - Lucario is thought to be a Legendary Pokémon due to the fact that it starred in a Pokémon movie, which is usually reserved solely for Legendary Pokémon. Another reason is due to the fact that at the time of its release the only way to get a Lucario was by evolving a Riolu which was only obtainable through an in-game event, and thus was only obtainable one time in the game.
 * Spiritomb - The DP Pokédex Book incorrectly states that Spiritomb is a Legendary Pokémon. Similar to Rotom, Spinda, and Delibird, this is just an error out of many in the DP Pokédex Book.
 * Rotom - Rotom is often thought of as Legendary because there is only one in a given game and it plays the Legendary Pokémon music once battled. It is also labeled as a Legendary in the DP Pokédex Book, although the same book bears several other errors (numbering in the double digits), both major and minor.
 * Zorua & Zoroark - Zoroark was thought to be a Legendary Pokémon because, like Lucario, it was the main focus of a movie, a feat normally given only to Legendary Pokémon. Like many other Legendary Pokémon, it was only available as an in-game event in Black & White and Black 2 & White 2 with only one being able to found in each game. In Black & White, a trainer needed an event shiny Raikou, Entei, or Suicune in order to activate the in-game event, and in Black 2 & White 2 it is only available by evolving N's Zorua. This might also be because Zoroark can be freed from a Master Ball in Super Smash Bros. 3DS, something usually only given to Legendaries or Mythicals.
 * Volcarona - Many people speculated on whether or not Volcarona was a Legendary Pokémon or not because of the fact that it can only be found one time in a game just like Legendary Pokémon and is found through an in-game event. Volcarona is found at the bottom of Relic Castle and is only accessible after the player character has defeated Team Plasma in Black & White.

Anime

 * Bonnie looked after a Zygarde that she nicknamed Squishy until the Team Flare crisis but they promises to see each other again one day.


 * Ash took care of a Cosmog as he promised Solgaleo and Lunala that he would then was nicknamed Nebby by Lillie. After evolving into Cosmeoem then into Solgaleo, Nebby left for the wild but did meet up with Ash a couple of times before the latter left to resume his travels.


 * Goh caught a recurring Eternatus when Chairman Rose tried to recreate the Darkest Day but lets it get sealed away so it would't cause the Galar Region anymore harm.

= Mythical Pokemon =

Mythical Pokémon (幻のポケモン Maboroshi no Pokémon) or Event-exclusive Pokémon, less commonly known as Mirage Pokémon, are a special group of Pokémon that are rarely seen by anyone in the world of Pokémon. Some are so rarely seen that people are unsure if they really exist, spurring scientists to do research. No Mythical Pokémon can be found under normal conditions; the only way to obtain these Pokémon is for the player to participate in "Pokémon events" commonly hosted by Nintendo around the world. Mythical Pokémon were once considered part of Legendary Pokémon outside of the Japanese media, until Generation V. In the spinoff Pokémon Ranger: Guardian Signs, Mythical Pokémon are referred to as rare Pokémon.

Mew
Mew, also known as the "Ancestor of all Pokémon," is considered the rarest Pokémon of all. It is a kind and powerful being that in the movie Mewtwo Strikes Back saves Ash and all the other Trainers invited to New Island.

Celebi was around the time of the release of the Generation II video games called the rarest Pokémon due to the fact that it was only available for one event which was in Japan exclusive for Pokémon Crystal. Now known, Celebi acts more like a chain to unlock other events in different video games. In Pokémon HeartGold and SoulSilver after obtaining a Celebi through an event, it will let the player travel through time to show the past between Silver and Giovanni which contains the actual hate of Silver against Team Rocket and his tough attitude.

It is known that Arceus is the 5th most powerful Pokémon of them all (competitively) and the first Pokémon that has a variety of types due to the plates it holds. The birth of Arceus was when it hatched from an egg out of a portal and it has prospered from then. Arceus is an event Pokémon by obtaining the Azure Flute.

= Ultra Beasts = The Ultra Beasts (ウルトラビースト Urutora Biisuto) are a group of Extradimensonal Pokémon introduced in Generation VII. They were revealed on September 6, 2016.

They are Pokémon native to a vastly different dimension to the world of the games the Ultra Space, causing them to develop as very strange, and often very strong. While the Ultra Beasts normally stay within Ultra Space, they can on occasion become stranded outside of it due to the formation of an Ultra Wormhole that leaves them unable to return. This can prove to be dangerous for anyone nearby, as the disorientation involved can often cause them to become violent.

Description
In the Alola region, rumors are flying about mysterious creatures known as Ultra Beasts. Ultra Beasts possess mighty powers and could pose a threat to humans and Pokémon, so they are feared. It appears that the Aether Foundation is also conducting research on these Ultra Beasts.

Known Ultra Beasts
A total of seven Ultra Beast species appear in Pokémon Sun and Moon, each of them called by a code name in addition to a real name. In Pokémon Ultra Sun and Ultra Moon it was revealed four new Ultra Beasts.

UB-01 Symbiont
UB-01 Symbiont (Japanese: UB01 PARASITE) is the first Ultra Beast shown. It was revealed on September 6, 2016.

UB-01’s body is composed of a glass-like substance. However, it’s constantly changing shapes, never settling on one.

While evidence of something like a survival instinct can be observed in UB-01, no one knows whether it has a will of its own or any emotions. It’s said that, for some reason, its movements resemble those of a young girl. Nihilego has a neurotoxin that inhibits the actions of the host rather than possession, making them stronger, more violent, but also reckless and oblivious of their actions. This probably isn't intentionally symbiotic as the goal of this is for the intoxicated to attack and destroy those that could be a hindrance to the Nihilego or its nest, such as predators or competitors; most likely other types of UB's.

UB-01 Symbiont originates from a world called Ultra Deep Sea.

UB-02
UB-02 has two known forms: UB-02 Absorption (Buzzwole) and UB-02 Beauty (Pheromosa). UB-02 (Japanese: UB02) is the second Ultra Beast shown. It was revealed on September 12, 2016 through the September issue of CoroCoro magazine.

UB-02 Absorption
UB-02 Absorption (Japanese: UB02 EXPANSION) was revealed on September 12, 2016 by some CoroCoro scans and officially two days later. It is exclusive to Pokémon Sun. At some point of the story, it battles Hala and Tapu Koko.

The extent of its strength is unknown. Its entire body is covered with bulging, powerful muscles. The full force of a punch powered by these muscles would be off the charts as it is able to pulverize a dump truck with a single punch. Its distinctively long mouth is said to be harder than diamonds. When absorbing a target's energy, it causes its own muscles to grow exponentially fast. Its flexing is thought to be a way of communicating. Buzzwole appears to use its arms as its primary weapon, probably due to it being the most powerful part of its body.

UB-02 Absorption originates from a world called Ultra Jungle.

UB-02 Beauty
UB-02 Beauty (Japanese: UB02 BEAUTY) was revealed on September 12, 2016 by some CoroCoro scans and officially two days later. It is exclusive to Pokémon Moon. At some point of the story, it battles Hala and Tapu Koko.

Its narrow, graceful legs allow it to accelerate with such explosive speed that people claim it can dodge lightning! It is said that any Pokémon that sees UB-02 Beauty, regardless of its own gender, will become infatuated with it and lose the will to battle. The exact reason for this reaction—whether it's an unidentified pheromone exuded by UB-02 Beauty or a hypnotic effect induced by its appearance—has not been determined. In terms of attacking, it seems to use prefer legs most of the time, most likely due to its insane speeds topped with legs.

UB-02 Beauty originates from a world called Ultra Desert.

UB-03 Lightning
UB-03 Lighting (Japanese: UB03 LIGHTNING) was revealed on November 14, 2016.

It raided a power plant, so people think it energizes itself with electricity. Astonishing electric shocks emanate from its entire body, according to witnesses. When it is low on energy, it will absorb electricity from the ground and enter a temporary tree-like state. Xurkitree has an organ that can produce energy, allowing it to discharge up to around one million volts of electricity at once.

UB-03 Lighting originates from a world called Ultra Plant.

UB-04 Blade
UB-04 Blade (Japanese: UB04 SLASH) was revealed by some CoroCoro scans on November 11, 2016. It is exclusive to Pokémon Sun.

It was observed cutting down a gigantic steel tower with one stroke of its blade. It seems not to attack enemies on its own, but its sharp body is a dangerous weapon in itself. It is very dangerous as every edge of its body is impossibly sharp, making it able to cut almost everything, an opponent included. Attacking would probably result in being cut down as Kartana could just move to a position in which the opponent attacks a sharp edge. It can easily avoid attacks by floating away, however. Due to i's ultra-thin body (And probably being made of paper), it is highly susceptible to fire and moisture.

UB-04 Blade originates from a world called Ultra Forest.

UB-04 Blaster
UB-04 Blaster (Japanese: UB04 BLASTER) was revealed by some CoroCoro scans on November 11, 2016. It is exclusive to Pokémon Moon.

UB-04 Blaster originates from a world called Ultra Crater.

UB-05 Glutton
UB-05 Glutton (Japanese: UB05 GLUTTONY) was revealed by some CoroCoro scans on November 11, 2016 and officially four days later.

This beast has an astounding appetite, and it will completely devour anything in front of its eyes. It’s said that it devours not only objects, but the ground, rivers, and even the seas.

Despite the abnormal amounts that this beast consumes, it’s said that it doesn’t produce any waste products. It’s possible that it’s completely converting everything it eats into energy to sustain itself, but the true details remain unknown.

UB-05 Glutton originates from a world called Ultra Ruin.

UB Burst
"UB Burst" (Japanese: UB BURST) was revealed on September 13, 2017. It is exclusive for Pokémon Ultra Sun.

UB Burst tricks targets into letting their guard down as it draws near with its funny gait, swaying this way and that—then shocks them by blowing up its own head without warning. Before they can recover their senses, it steals their vitality, which it’s said to use as a source of energy.

Its head is made up of a collection of curious sparks, and it appears to have the ability to freely remove its own head and make it explode.

UB Assembly
"UB Assembly" (Japanese: UB LAY) was revealed on September 13, 2017. It is exclusive for Pokémon Ultra Moon.

While UB Assembly may appear to be made up of stones stacked atop one another, apparently each “stone” is in fact a separate life-form, and this UB is made up of an assemblage of these life-forms.

When confronting another, or when feeling particularly enraged, the eyes on each of these stones begin to glow red.

UB Adhesive
"UB Adhesive" (Japanese: UB STICKY) was revealed on October 5, 2017.

UB Adhesive displays many emotions, and it’s said to be able to understand human speech if it spends enough time together with them.

Their large heads are filled with venom, and they fire this venom from the poisonous needles on top of them.

UB Adhesive originates from Ultra Megalopolis, where it is popular as Starter Pokémon.

UB Stinger
"UB Stinger" (Japanese: UB Stinger) is the evolution of UB Adhesive.

UB Stinger has stingers on its lower body and each shoulder. The powerful poison it fires from the largest stinger, on the end of its abdomen, can travel over a staggering six miles, It may look like a huge stomach, but Naganadel’s abdomen contains its brain and hundreds of liters of poisonous liquid. This poisonous liquid is peculiar, being both highly adhesive and luminescent. The stingers that attach to its abdomen are directly connected to its brain. As a result, it hates to have these stingers touched. It will furiously attack anyone who touches them.

UB Stinger's homeworld just like its pre-evolution, is Ultra Megalopolis.

Anime

 * Ash:
 * Briefly caught a Buzzwole then returned it home.
 * Caught a Poipole but released it back to the wild, which during that time evolved into Naganadel. Sometime later, Naganadel returned to help Ash in a time of need and battled alongside him against Professor Kukui before returning home once more.
 * Briefly caught a Stakataka and a Pheromosa then returned them both home.
 * Lana and Lillie temporally caught a Xurkitree and Blacephalon as they return them to their proper homes.

Trivia

 * All the Ultra Beasts share a distinctive metallic hum in their cries.
 * All Ultra Beasts' base stats and all the levels at which they learn moves are prime numbers.
 * The only exception is Naganadel, as it has a Speed stat of 121. 121 is, however, 11 squared.
 * The only Ultra Beasts to share a type combination are Buzzwole and Pheromosa. They are both Bug/Fighting-type Pokémon.
 * Kartana and Celesteela, the respective exclusives of Sun and Moon, are complete opposites. Kartana is one of the lightest Pokémon (at 0.2 lbs.), making it the lightest Ultra Beast, while Celesteela is one of the heaviest Pokémon (at 2204.4 lbs.), making it the heaviest Ultra Beast. Likewise, Kartana is the smallest Ultra Beast (at 1'00") and Celesteela the largest (at 30'02").
 * Despite not being considered Legendary Pokémon, they share some similarities with them. For instance, they are in the Undiscovered Egg Group, they are genderless, their Pokédex backgrounds have different colors, have special battle music, have at least 3 IVs of 31, have BST's of 570 (not including Poipole and Naganadel), and are all scripted encounters (meaning they do not disappear until caught) or gifts from in-game trainers.
 * Despite them being Pokémon in the anime, Meowth cannot understand the language of Ultra Beasts, possibly due to their alien-like nature.
 * The first seven Ultra Beasts may be based on the Seven Deadly Sins.
 * Poipole is the only Ultra Beast that can evolve.
 * The concept of Ultra Beasts was based on the concept of invasive species.
