In Japanese media, Mythical Pokémon and Legendary Pokémon have always been presented as distinct groups. In non-Japanese media prior to Generation V, Mythical Pokémon and Legendary Pokémon were both considered to be Legendary Pokémon (and the term Mythical Pokémon was unused, with some fans calling Mythical Pokémon "Event Legendaries", reflecting how they usually must be obtained at an event, but they are not a subset of them); since Generation V, the two groups are presented as distinct groups in all official media. In Pokémon Ranger: Guardian Signs, Mythical Pokémon are referred to as rare Pokémon.
In the core series
Mythical Pokémon are regarded as among the rarest in Pokémon world mythology. Some are seemingly unknown to most people, while others are thought of as stuff of legends. They typically receive minimal exposure during normal gameplay, usually alluded to in vague hints. They are then revealed to players months or years after the debut of their respective generation. Upon being revealed, they are celebrated across the numerous media, often starring in movies and being featured prominently in merchandise.
When they are first revealed, Mythical Pokémon cannot be obtained in the core series games in the course of normal gameplay. They can typically only be obtained by Mystery Gift (either directly, or using an event item). They are distributed to players via Mystery Gift on special occasions such as screenings of Pokémon movies, events in retail stores, online distributions, the Pokémon 20th Anniversary, etc., or may be received via spin-off games that feature special connectivity. Mythical Pokémon are usually unobtainable in regular gameplay, with the vast majority of them only being obtainable via these events.
The gender of every Mythical Pokémon is unknown. Almost all Mythical Pokémon cannot evolve, with the exception of Meltan, and most cannot breed, although Manaphy and Phione can be bred with Ditto to produce Phione Eggs.
Much like how starter Pokémon appear at the beginning of each regional Pokédex and their generation's portion of the National Pokédex, Mythical Pokémon typically appear at the very end, and Legendary Pokémon immediately before them. The Mythical Pokémon Victini is the only exception, which appears at the start of the Unova Pokédex as #000, coming before the region's starter Pokémon.
No Mythical Pokémon is required to complete the Pokédex for rewards such as the diploma, except in Pokémon Omega Ruby and Alpha Sapphire, which require the player to obtain Deoxys for the National Pokédex diploma due to it being available as part of the Delta Episode.
Despite the first Mythical Pokémon, Mew, being added to the original games right before release, the concept of "illusory monsters" (Mythical Monsters) already existed in Satoshi Tajiri's pitch for Capsule Monsters. They were said to be hard to encounter, hard to catch or be impossible to catch if the player missed their chance. For example, there would be a "Green Dragon" that could only be found rarely in a specific area of a dungeon, and it would have taken around two hours to find and catch.
Multiple Mythical Pokémon
Sometimes, the player is able to acquire multiple Mythical Pokémon of the same species by trading or transferring them from multiple games, or by attending multiple real-life distributions. There are other instances of multiple Mythical Pokémon:
- It is possible to acquire multiple Phione Eggs by breeding Manaphy with Ditto.
- The Pokédex states that at the end of Melmetal's lifespan, its small shards left behind will eventually be reborn as Meltan. This indicates that multiple Meltan are born, but also there could potentially be multiple Melmetal if they evolve. Additionally, multiple Meltan are seen together in promotional videos.
- Zarude lives deep within dense forests in a pack with others of its kind.
In the anime
Mythical Pokémon typically make their anime debut in a movie, rather than first appearing in a normal episode. Most are held in very high regard in all forms of canon, though their status varies between the games and anime.
In the anime, they are often only seen by special Trainers, such as Ash Ketchum and people who have a special connection to them. Ill-intentioned people often seek to possess them, due to their power and rarity. Tobias is the first Trainer seen to own a Mythical Pokémon in the anime, using the Mythical Pokémon Darkrai and the Legendary Pokémon Latios in the Lily of the Valley Conference. Another character to own a Mythical Pokémon was Dia, an inhabitant of the Ultra Ruin, who owns the Mythical Pokémon Zeraora. Ash owns a Mythical Pokémon, Melmetal, which he caught as a Meltan in Got Meltan? after it befriended his Rowlet.
List of Mythical Pokémon
Of the 908 Pokémon species, 21 are Mythical Pokémon (2.31%). Including Phione, there are 22 Mythical Pokémon (2.42%). Each generation has introduced at least one Mythical Pokémon.
One Mythical Pokémon was introduced in Generation I.
Mew is a Psychic-type Mythical Pokémon. It is believed to contain the genetic codes of all Pokémon in its DNA. Initially thought to be extinct, a scientific team has reported sightings of it in Guyana. Mewtwo was created after a series of experiments based on Mew, and is thus considered to be part of a Legendary duo with it.
Mew established the convention of Mythical Pokémon with its release in Pokémon Red and Green. Its base stat total of 600 and the stat distribution of 100 to each stat also created a trend followed by several Mythical Pokémon released later in the series. Pokémon following this trend include Celebi, Jirachi, Manaphy, Land Forme Shaymin, and Victini.
Designed by Shigeki Morimoto, it was initially unavailable and unknown to players, before being revealed by Satoshi Tajiri in the spring of 1996 in an issue of CoroCoro. Initially, a lottery was held to distribute the Pokémon experimentally to a limited number of players, and a promotional card was included in the January issue of CoroCoro. Supposed methods of obtaining Mew, passed on through word-of-mouth, contributed to the success of the Pokémon series. Its success was mirrored in the west with the eventual release of Pokémon Red and Blue, making Mew a prominent character of the first generation, co-starring in the first animated movie, Mewtwo Strikes Back.
In Pokémon Emerald, with the Old Sea Chart event item, the player can travel to Faraway Island, where they can encounter a wild Mew, after they complete a game of hide-and-seek with it. This is the only time Mew has appeared in the wild (excluding glitches).
In Pokémon Sun and Moon, it can use a unique Z-Crystal known as the Mewnium Z, which allows it to perform the Z-Move Genesis Supernova. In Sun and Moon, the Mewnium Z was only available through a Pokémon Bank promotion, but it is available in Pokémon Ultra Sun and Ultra Moon by showing a Mew to a man in the Tide Song Hotel in Heahea City.
One Mythical Pokémon was introduced in Generation II.
Celebi shares a special connection with the Ilex Forest in Johto and the Agate Village's Relic Forest in Orre, having the Ilex Forest shrine and the Relic Stone as monuments to honor it in those areas.
Introduced in Pokémon Gold and Silver, Celebi was the second Mythical Pokémon to be released. Created by Ken Sugimori, it was dubbed the "New Mew" soon after being revealed because of its similar size and stats with Mew, as well as the status of being the last in the National Pokédex as of its generation and being unobtainable through normal gameplay. It first became available in Nintendo Space World 2000 in Japan, with numerous other events coming in the following years worldwide.
In Pokémon Crystal, if the player has the GS Ball Key Item, they can encounter a wild Celebi in Ilex Forest. In the original Game Boy Color release of Pokémon Crystal, this item was distributed via Mobile System GB in Japan (it was not available outside of Japan). In the Nintendo 3DS Virtual Console release, the player can obtain the GS Ball in normal gameplay in Goldenrod City after entering the Hall of Fame, making this the second time a Mythical Pokémon can be encountered in normal gameplay (after Deoxys in Pokémon Omega Ruby and Alpha Sapphire).
In Pokémon Colosseum, Celebi appears if the player uses a Time Flute at the Relic Stone, descending from above and then flying around a Shadow Pokémon to instantly purify it. In the Japanese version of the Pokémon Colosseum Bonus Disc, the player can obtain Celebi after purifying all 48 Shadow Pokémon in the game.
Two Mythical Pokémon were introduced in Generation III.
Jirachi is a Steel/Psychic-type Mythical Pokémon. It is said to able to grant any wishes written on the tags on its head once awake. It only wakes up for seven days once every thousand years. If in danger, it will fight without waking up.
Jirachi was introduced in Pokémon Ruby and Sapphire and it, like Mew and Celebi, is a Psychic-type Mythical Pokémon with 100 for each base stat. It was revealed in 2003 in the context of the sixth movie, Jirachi: Wish Maker, in which it starred. It first became available in Japan to players who pre-ordered tickets to the movie, with other limited distribution events following throughout the year. Its distribution in the west was altered, as it was included in the Pokémon Colosseum Bonus Disc in the United States and in Pokémon Channel in Europe and Australia. Unlike its predecessors, Jirachi does not have an extensive story or event in the core games, with its lore limited to a few indirect references.
Deoxys is a Psychic-type Mythical Pokémon. It mutated from a space virus when exposed to a laser beam. It is able to change its form, altering its appearance and traits. The crystal on its chest acts as its brain, as well as a defense mechanism.
Although it retained a base stat total of 600, Deoxys was the first Mythical Pokémon to have a base stat distribution other than 100 in every stat. Additionally, Deoxys introduced the concept of Formes which altered the distribution of stats.
In spite of being included in the preceding games, Pokémon Ruby and Sapphire, Deoxys was first made available in Pokémon FireRed and LeafGreen. Officially revealed in late 2003 as a leading character in Destiny Deoxys, players were first able to capture Deoxys by use of the AuroraTicket, which provided access to Birth Island, where it appears in-game.
While Deoxys originally had little impact on the story of Generation III, Omega Ruby and Alpha Sapphire introduced the Delta Episode, a mission following the player's first completion of the Hoenn League in which the player must stop a meteor from hitting the planet by destroying it with a befriended Rayquaza, revealing a Deoxys within. This marked the first time a Mythical Pokémon was available in-game without the need to attend an event or use a download code.
Contrary to its classification in Pokémon Omega Ruby and Alpha Sapphire, PokémonCenter.com as well as the Scholastic book Official Guide to Legendary and Mythical Pokémon call Deoxys a Legendary Pokémon rather than a Mythical Pokémon.
Manaphy and Phione
- Main article: Sea guardians
Manaphy is a Water-type Mythical Pokémon, and Phione is a Water-type Pokémon. Manaphy are born on cold seafloors, also swimming great distances to return to their birthplace, and are born with a wondrous power to bond with any kind of Pokémon. Phione live in warm seas, using the inflation sac on their heads to search for food and to drift in packs, always returning to the place of their birth. Together, these two Pokémon species make up a Mythical duo of a parent and child.
Manaphy and Phione have the unique ability among Mythical Pokémon to breed with Ditto in captivity to produce Phione. Phione, cannot, however, evolve into Manaphy. The only legitimate way to obtain a Phione in-game is to breed a Manaphy or another Phione. Phione is the weaker of the two Pokémon, having 80 distributed into each stat instead of 100. It is impossible to get a Manaphy Egg through this method.
Phione's status as a Mythical Pokémon is disputed, with even official sources contradicting one another. Further information can be found here.
Manaphy was first made available to those who pre-ordered tickets for Pokémon Ranger and the Temple of the Sea in Japan. Anyone who pre-ordered tickets received a voucher which could be redeemed from June 17 to August 31, 2006, to access Pokémon Ranger's Ranger Net mission, "Recover the Precious Egg!". Once completed, a Manaphy Egg could be transferred to Pokémon Diamond and Pearl and hatched. Pokémon Ranger's sequel games, Pokémon Ranger: Shadows of Almia and Pokémon Ranger: Guardian Signs have similar downloadable missions where Manaphy Eggs can be transferred to not only Diamond and Pearl but Pokémon Platinum and Pokémon HeartGold and SoulSilver as well. Manaphy has since been released through distribution as most other Mythical Pokémon.
Darkrai is a Dark-type Mythical Pokémon. It chases people and Pokémon away from its territory by causing them to experience deep, nightmarish slumbers. However, it is merely protecting itself and means no harm. It is particularly active on moonless nights.
Darkrai is heavily connected with the sleep status condition, as reflected by its signature Ability, Bad Dreams, and its signature move Dark Void. It also learns related moves, such as Nightmare. From Generation VII onward, Dark Void fails if used by any other Pokémon.
Darkrai has appeared with an antagonistic role in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness and Pokémon Mystery Dungeon: Explorers of Sky, specifically as an enemy of the Legendary Pokémon Cresselia. In Pokémon Diamond and Pearl, and Pokémon Platinum, the player must also cure Sailor Eldritch's son of a nightmare using a Lunar Wing from Cresselia. The two Pokémon's relationship is further cemented in the anime episode Sleepless in Pre-Battle!, in which Cresselia is revealed to actively drive Darkrai away from Canalave City. Collectively, the two Pokémon are known by a fan designator, the lunar duo.
Darkrai was officially revealed in February 2007, and was first made available to those who owned Pokémon Diamond and Pearl and watched Pokémon: The Rise of Darkrai in Japan from release to September 9, 2007. Other distributions were made available afterward. Notably, in Pokémon Platinum, an event gave the Member Card to players over Nintendo Wi-Fi Connection, activating an in-game event which allowed for capture of Darkrai on Newmoon Island.
Shaymin is a Grass-type Mythical Pokémon. Shaymin live in flower patches and avoid detection by curling up to look like a flowering plant. Shaymin are able to dissolve toxins in the air to transform ruined land into a lush field of flowers. When sensing gratitude, the flowers all over its body burst into bloom.
When exposed to the blooming Gracidea flower during the daytime, Shaymin becomes Sky Forme Shaymin. Sky Forme has altered stats from its original Land Forme and takes on the Flying type as a secondary type. Shaymin will revert to its Land Forme at night, while frozen or, before Generation VII, when deposited into the Pokémon Storage System.
Shaymin was officially revealed in February 2008 as a star of Giratina and the Sky Warrior, and in early June 2008, its Sky Forme was revealed. Shaymin was first made available to owners of Pokémon Pokémon Diamond and Pearl during the theatrical showing of the movie in Japan from July 19 to September 30, 2008. Other distributions were later made available, but a notable distribution occurred for North American and PAL players from September 28 to November 8, 2009, through the distribution of the Key Item Oak's Letter. This item allowed players to access Seabreak Path and capture a Shaymin in Flower Paradise.
Arceus is said to have created the regions of Sinnoh and Ransei, and may have created the entire Pokémon universe. According to legend, Arceus also created two Legendary trios. First, it created the creation trio: Dialga, Palkia, and Giratina, to balance time, space, and antimatter. Then, it created the lake guardians: Uxie, Mesprit, and Azelf, and created spirit, and has since been residing in the Hall of Origin, which will connect to Spear Pillar when the Azure Flute is played there. As their creator, it is both trios' trio master. It is unique in this regard, as it is the only Mythical Pokémon to be the master of a Legendary trio, and the only Pokémon to be the master of two.
Arceus is often referenced in Sinnoh's mythology as the "Original One". Both Canalave City's library and the Plates scattered across Sinnoh describe Arceus' creation of the universe. It receives more exposure in-game than Mythical Pokémon traditionally find. It is the titular character of the upcoming Pokémon Legends: Arceus, and a major focus of the Generation V spin-off game Pokémon Conquest.
Arceus was officially revealed on February 14, 2009, and first made available to players on July 18 of that year, the day when Arceus and the Jewel of Life premiered in Japan. Arceus was revealed to international audiences on August 3, 2009.
Four Mythical Pokémon were introduced in Generation V.
Victini is a Psychic/Fire-type Mythical Pokémon. It is said that this Pokémon brings victory and that trainers with Victini always win, regardless of the type of encounter. It creates an unlimited supply of energy inside its body, which it shares with those who touch it. When it shares the energy it creates, that being's entire body will be overflowing with power.
Victini was revealed in a preview for the fourteenth Pokémon movie which was shown at the end of Zoroark: Master of Illusions. It was made available in-game by use of the Liberty Pass, an event item which was distributed across varying time periods worldwide. The Liberty Pass allowed players to travel to Liberty Garden. Once there, the player would be challenged by members of Team Plasma and could find Victini in the basement of the lighthouse.
Keldeo is a Water/Fighting-type Mythical Pokémon and the fourth member of the Swords of Justice. Its initial appearance in Pokémon Black and White as well as the default in Black 2 and White 2 is its Ordinary Form. In Black 2 and White 2, Keldeo has a second form, its Resolute Form. After triggering an event in the Pledge Grove, the other Swords of Justice—Cobalion, Virizion, and Terrakion—will teach Keldeo Secret Sword. It will remain in its Resolute Form as long as it knows Secret Sword.
In The Crown Tundra, Keldeo can be found in Ballimere Lake after completing Sonia's sidequest to catch the other three Swords of Justice. Placing the other Swords of Justice in the player's party and cooking curry on the small island in the middle of the lake with the cooking pot on it will cause a wild Keldeo to appear, making it the third Mythical Pokémon available in regular gameplay without an event.
Keldeo debuted in the fifteenth Pokémon film Kyurem VS. The Sword of Justice, along with the other Swords of Justice.
Meloetta is a Mythical Pokémon with two different Formes, Aria Forme and Pirouette Forme. Aria Forme is Normal/Psychic-type while Pirouette Forme is Normal/Fighting-type. Legend says that it once played a song and danced so lightly, it filled people's hearts with joy. However, when sorrow darkened the world, it lost the melody. At the same time, its red shoes were lost somewhere. Using Relic Song changes its form.
Genesect is a Bug/Steel-type Mythical Pokémon. Originally an ancient insect Pokémon who was feared as the strongest of hunters more than 300 million years ago, Team Plasma revived it from a Fossil and altered it with cybernetic upgrades in an attempt to create the strongest Pokémon in existence. It uses special Drives to make variations to its signature move, Techno Blast.
Genesect had its anime debut in a group called the Genesect Army that had escaped from Team Plasma's P2 Laboratory. They were first seen in N's visions in The Name's N!, and later on starred in the sixteenth Pokémon movie Genesect and the Legend Awakened, in which they battled Mewtwo in New Tork City.
Three Mythical Pokémon were introduced in Generation VI.
Diancie appeared in Diancie and the Cocoon of Destruction, where it is the princess of the Diamond Domain. It is given the objective to create a new Heart Diamond for the domain, as the current one is faltering, and seeks Xerneas and its Fairy Aura to gain the power to do so. It is sought after by multiple thieves who desire its diamonds and ultimately gains the power to make a Heart Diamond in an attempt to protect its friends from Yveltal. It appears with three Carbink servants and an elder Carbink named Dace.
It is the only Mythical Pokémon with the ability to Mega Evolve, which allows it to transform into Mega Diancie.
Hoopa is a Mythical Pokémon that has two Formes. Hoopa Confined, the Mischief Pokémon, is a Psychic/Ghost-type Pokémon, while Hoopa Unbound, the Djinn Pokémon, is a Psychic/Dark-type Pokémon. It is said to be able to be able to use its gold rings to warp space in order to take things it likes and carry them away into alternate dimensions. It is also said to have carried away an entire castle in an attempt to steal all of its treasure according to some legends. Using an item known as a Prison Bottle, Hoopa Confined can transform into Hoopa Unbound and remain so for three days, after which it transforms back to Hoopa Confined. It will also transform back if deposited in the PC. Hoopa Unbound was first introduced in Pokémon Omega Ruby and Alpha Sapphire. Hyperspace Fury fails if used by any Pokémon other than Hoopa Unbound, such as if used by Hoopa Confined.
Hoopa appeared in Hoopa and the Clash of Ages in both its Confined and Unbound forms.
Volcanion is a Fire/Water-type Mythical Pokémon. It uses steam from arms on its back to disappear in fog and blow away mountains. It lives in mountains uninhabited by humans. According to the editor of the Lumiose Press, Volcanion may have an organ unique to it inside its body that is hot enough to instantly vaporize water into steam to use in attacks. There is also a report that suggests that Volcanion may have used its power to destroy a mountain range where Kalos was founded.
It made its anime debut in Volcanion and the Mechanical Marvel, in which it went on a mission to rescue Magearna from a power-hungry man named Alva. It initially did not trust humans, but it changed its mind after seeing how Ash was determined to protect Magearna.
Five Mythical Pokémon were introduced in Generation VII.
Magearna is a Steel/Fairy-type Mythical Pokémon. It was made by humans 500 years ago. Its body is entirely metallic and contains tricky machinery and a secret hidden inside. Its core, known as a Soul-Heart, is its true body.
It was first revealed in the March 2016 issue of CoroCoro. It is available via a QR Code event in Sun, Moon, Ultra Sun, and Ultra Moon, making it the only Mythical Pokémon available through an indefinitely active event.
Magearna has a second form known as its Original Color form. The difference in this form is purely cosmetic; it is gold and red. This form existed in the Generation VII games but was not distributed until Generation VIII, where it can be received as a reward for completing the National Pokédex in Pokémon HOME.
It acted as one of the main stars of Volcanion and the Mechanical Marvel. In the film, it is said to have been created by a brilliant scientist named Nikola five centuries ago. In the present day, it was kidnapped by Alva, a corrupt minister of the Azoth Kingdom who sought to use Magearna's powers for his own selfish purposes.
Marshadow is a Fighting/Ghost-type Mythical Pokémon. Its very existence is the stuff of legends, as very few people have ever seen it. Marshadow is known to travel through the shadows of humans and Pokémon in order to become stronger by copying the power of movements within said shadows. It has a form-like transformation known as Zenith Marshadow which is triggered when its fighting spirit starts burning.
It can utilize a unique Z-Crystal, the Marshadium Z, which allows it to use the Z-Move Soul-Stealing 7-Star Strike. This Z-Crystal came with a promotional Marshadow in Pokémon Sun and Moon but is also available in Pokémon Ultra Sun and Ultra Moon by showing Marshadow to a man in the Tide Song Hotel in Heahea City.
Marshadow was officially revealed on April 7, 2017.
Marshadow appeared in I Choose You! where it acted as a guide to Ash and his friends.
Zeraora is an Electric-type Mythical Pokémon introduced in Pokémon Ultra Sun and Ultra Moon. Zeraora can channel a powerful magnetic field trough the electric currents located in its paw-pads. The magnetic field allows it to levitate and fly through the sky and travel as fast as a lightning strike.
It was revealed on April 8, 2018.
Zeraora was again made available for a limited time to celebrate the release of The Isle of Armor Expansion Pass for Pokémon Sword and Shield. If one million players defeated Zeraora in Max Raid Battles on the Isle of Armor, players would get a commemorative Shiny Zeraora in Pokémon HOME.
Zeraora appeared in The Power of Us.
Meltan and Melmetal
Meltan is a Steel-type Mythical Pokémon introduced in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!. It first appeared in Pokémon GO on September 21, 2018, by way of large numbers of Ditto disguised as Meltan. Meltan's identity was revealed on September 25, 2018. On October 24, 2018, it was revealed that Meltan can evolve into another Steel-type Mythical Pokémon, Melmetal.
Meltan is known to be curious and expressive. It is instinctively drawn to metal that it could absorb, as well as other Meltan, in order to combine and form Melmetal. Melmetal was worshiped in ancient times for creating metal.
Meltan can be caught when opening the Mystery Box in Pokémon GO, which causes many Meltan to spawn around the player for a limited time. Meltan can only evolve into Melmetal in Pokémon GO, requiring 400 Meltan Candies.
Meltan is the only Pokémon, and by extension the only Mythical Pokémon, that is only obtainable in Pokémon GO. Melmetal was once the same, but has since been distributed as a gift in Pokémon HOME given for transferring Pokémon from GO using the GO Transporter, this gift is a special Melmetal capable of Gigantamaxing in Pokémon Sword and Shield.
Unlike previous generations, there were no new Mythical Pokémon in the game data or code of Pokémon Sword and Shield when the games were released. However, a new Mythical Pokémon was added to the game in update 1.2.0.
Zarude is a Dark/Grass-type Mythical Pokémon. It can use the vines from its body for a variety of purposes such as healing. It is known to live in packs, residing in dense forests. Zarude has a quick wit which its uses in battle along with its claws and other means of attacking.
Zarude was heavily featured in Secrets of the Jungle.
