Pokémon fusion

Under rare circumstances, some Pokémon have been known to combine with other Pokémon or even people. This phenomenon, sometimes called fusion, has appeared across various Pokémon media, including the games, anime, and manga.

Multiple Meltan in the process of fusing to become Melmetal in the anime

A few Pokémon Evolutions are said to result from the merging of two or more Pokémon, with separation resulting in devolution in certain cases. Other Pokémon can combine as part of a form change. Furthermore, some Pokémon are actually themselves a combination of multiple Pokémon.

Additionally, Pokémon fusion has been a popular subject in the Pokémon fandom and is the focus of some notable fan projects and websites.

List of Pokémon fusions

Pokémon fusion was first introduced in Generation I, with several Pokémon that can evolve through fusion (though not actually possible within the core series games, only being mentioned in the Pokédex), as well as a few Pokémon that are actually composed of multiple Pokémon combined into one. Starting in Generation V, Pokémon that fuse via form change were introduced with the addition of Kyurem, a Legendary Pokémon capable of changing forms by fusing with Reshiram or Zekrom.

Some Pokémon's status as fusions may be inconsistent between official sources. Additionally, some Pokémon may be composed of entities that appear to be Pokémon themselves, but are not explicitly identified as such.


In the games, Dugtrio is often referred to as three Diglett triplets. However, the Pokédex also states that Dugtrio are actually three Diglett that emerged from one body. This is contradicted by the anime episode The Underground Round Up, which instead refers to Dugtrio as being formed when three Diglett combine.

Slowbro and Slowking

If a Shellder bites on to a particular part of Slowpoke's body, Slowpoke may evolve, causing Slowpoke and Shellder to combine and change in appearance. If the two are separated, they will devolve back into their components. Even after Evolution, Shellder is still considered a Shellder despite its changed appearance.

  • If Shellder bites on to Slowpoke's tail, Slowpoke will evolve into Slowbro.
  • If Slowbro Mega Evolves, the Shellder will grow and take over most of Slowbro's body.
  • If Shellder bites on to Galarian Slowpoke's arm while Slowpoke wears a Galarica Cuff, Slowpoke will evolve into Galarian Slowbro.
  • If Shellder bites on to Slowpoke's head while Slowpoke wears a King's Rock, Slowpoke will evolve into Slowking.
  • If Shellder bites on to Galarian Slowpoke's head while Slowpoke wears a Galarica Wreath, Slowpoke will evolve into Galarian Slowking.

This method of Evolution has only been shown outside of the core series games, though it is mentioned in the Pokédex.

Magneton, Magnezone, and Sandy Shocks

Three Magnemite link together to evolve into Magneton, and stay merged as Magnezone.

This method of Evolution is only shown in Pokémon Snap. In the core series games, it is only mentioned in the Pokédex. Additionally, Pokémon Snap is one of the few times that two Magnemite have been shown bonding, similar to a Magneton. However, when a picture is taken, they are still called Magnemite. Two Magnemite are also seen linked together in Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team and Pokémon Mystery Dungeon: Rescue Team DX, but it was stated to be a failed Evolution, due to the lack of a third Magnemite.

Relatedly, the Paradox Pokémon Sandy Shocks appears to be an ancestor of Magneton composed of three units that resemble ancient versions of Magnemite.

Exeggcute and Exeggutor

Exeggcute consists of a cluster of six Exeggcute. If separated, they use their telepathy to quickly gather again. Until the six are gathered, Exeggcute is not able to maintain balance. The Exeggcute combine after evolving into Exeggutor. Eventually, one of Exeggutor's heads will fall off and become a single Exeggcute, which will telepathically communicate with others in order to quickly join and form a new cluster of six.


Two Koffing fuse together to evolve into Weezing, which has been referred to as a "twinned Koffing".

This method of Evolution has never been shown in any Pokémon media, though it is mentioned in the Pokédex. The Pokédex similarly states that triplet Weezing have been found, but this has also never been shown.


Kangaskhan holds a baby in its pouch. The baby rarely leaves its pouch unless it is safe to do so, at least until it is three years old and has learned to find food and survive on its own. When Kangaskhan Mega Evolves, the baby leaves its pouch and temporarily transforms, seeming to have grown up slightly, now able to fight alongside its mother. When the mother sees the back of her Mega-Evolved child, it makes her think of the day when her child will inevitably leave her.


Mantine is often seen with a Remoraid attached to its fin, treated as part of Mantine itself. Mantine evolves from Mantyke when leveled up with a Remoraid in the party, though the Remoraid is not removed from the player's party when this occurs. Since Generation IV, Remoraid is no longer included in Mantine's sprites and models, except in Pokémon HOME.

A Shiny Mantine in Pokémon HOME will also have a Shiny Remoraid attached to it.

Metang and Metagross

Two Beldum fuse together to evolve into Metang, and two Metang fuse to evolve into Metagross. When Metagross Mega Evolves, it temporarily links up with two more Beldum and a Metang.

This method of Evolution has never been shown in any Pokémon media, though it is mentioned in the Pokédex. In Saved by the Beldum, the only anime episode to date to show a Beldum Evolution, when Morrison's Beldum evolves into Metang, it "creates" another Beldum and newly developed main body to evolve, instead of fusing with another Beldum. Despite this, in The Synchronicity Test!, the Pokédex claims that "Metang is created from the union of two Beldum."

Combee and Vespiquen

Combee is a trio of three Pokémon that joined together to become one. Additionally, many Combee can cluster together to form a beehive. The bodies of the three Pokémon comprising female Combee appear to merge after evolving into Vespiquen.


When two Vanillish get stuck together, they evolve into Vanilluxe.

This method of Evolution has never been shown in any Pokémon media, though it is mentioned in the Pokédex.

Klink, Klang, and Klinklang

Klink consists of two twin minigears. Klang is composed of a minigear and big gear; if the minigear it launches at a foe doesn't return, it will die. Klinklang is composed of a minigear and big gear; dialogue between the two faced gears in the Pokémon Mystery Dungeon series suggests that both gears are independently sentient from one another.[1] However, the spiked gear and red core it gains after evolving do not appear to be alive.


Kyurem is a Legendary Pokémon that is stated to await a hero to fill its body with either truth or ideals. When using the DNA Splicers, Kyurem can undergo a process called Absofusion (Japanese: 吸収合体(きゅうしゅうがったい) Absorb Union) to absorb either Reshiram or Zekrom into itself, fusing into either White Kyurem or Black Kyurem. The fusion is stated to be result of Kyurem's genes being similar to that of Reshiram or Zekrom. The fusion will end if Kyurem is defeated or the DNA Splicers are used again.

The "original dragon" of Unova legend was a single Pokémon that eventually split into Reshiram, Zekrom, and Kyurem.

In Kyurem VS. The Sword of Justice, Kyurem can swap between all three of its forms without need of Zekrom or Reshiram.

If Kyurem is Shiny, its fusions will also be Shiny. The coloration of Reshiram or Zekrom will not affect the coloration of their respective fusions.

Doublade and Aegislash

When Honedge evolves, it divides into two swords to become Doublade, which cooperate via telepathy to coordinate attacks and slash their enemies to ribbons. These swords appear to recombine into one large sword when Doublade evolves into Aegislash. It is not stated whether Doublade's two swords are themselves considered Pokémon.

Binacle and Barbaracle

Binacle is frequently referred to as two Binacle that live together on one rock, and it is stated that when they fight, one of them will move to a different rock.

Some Pokédex entries state that Barbaracle is formed when two Binacle multiply into seven. However, Barbaracle's entry in Pokémon Sword states that Barbaracle is formed when seven Binacle come together.


Zygarde and its various forms are all composed of multiple Zygarde Cores and Zygarde Cells. It is unclear if the Cores and Cells are themselves considered Pokémon, as they cannot use moves or battle on their own. The composition of forms are called an assembly. Zygarde can be assembled either with usage of the Reassembly Unit found at the Aether Base on Alola's Route 16SMUSUM or with usage of a Zygarde CubeSwSh.


Multiple Wishiwashi can school together to change forms into their School Form.


Necrozma can forcibly fuse itself with Solgaleo or Lunala as body armor to become Dusk Mane Necrozma or Dawn Wings Necrozma, respectively, taking complete control of both the body and mind of the host. The fusion can be achieved by using the N-Solarizer for Solgaleo or N-Lunarizer for Lunala. Necrozma uses this fusion to help maintain and store the necessary light to become Ultra Necrozma. The fusion will end if Necrozma is defeated or the respective items are used again.

If Necrozma is Shiny, its fusions will also be Shiny. The coloration of Solgaleo or Lunala does not affect the coloration of their respective fusions.


Stakataka appears to be made up of many life-forms stacked up on top of each other. It is not stated whether these life-forms are themselves considered Pokémon.


Many Meltan combine to evolve into Melmetal.

This method of Evolution has been shown in a promotional video,[2] as well as in the anime, and is referenced in the Pokédex in Pokémon HOME. Meltan cannot evolve in the core series games, instead evolving in Pokémon GO after using 400 Meltan Candy.


Falinks consists of six units that work together as one Pokémon. Five of them are troopers, and the one that stands at the front is the brass. They constantly change formations as they battle, and are capable of being separated and reunited.

Dracozolt, Arctozolt, Dracovish, and Arctovish

The fossil Pokémon of Galar, Dracozolt, Arctozolt, Dracovish, and Arctovish, each appear to be hybrids of two extinct Pokémon spliced together from two different fossils.

Drakloak and Dragapult

Drakloak consists of Drakloak itself and a Dreepy that it carries on its head. It battles alongside Dreepy and dotes on them until they successfully grow up and evolve. If a Drakloak is defeated in a battle, its Dreepy will wander off without a second thought. Without a Dreepy to place on its head and care for, it gets so uneasy it'll try to substitute any Pokémon it finds for the missing Dreepy. Similarly, outside of battle, Dragapult keeps Dreepy in the holes on its horns. Once a fight starts, it launches the Dreepy like supersonic missiles. Shiny Drakloak and Dragapult will also have Shiny Dreepy.


Calyrex can use the Reins of Unity to unite with either Glastrier or Spectrier to form Ice Rider Calyrex or Shadow Rider Calyrex. Unlike the fusions of Kyurem and Necrozma, this fusion appears to simply be Calyrex riding the Legendary Pokémon, instead of involving the Pokémon's bodies physically merging. Calyrex gains a cape and crown-like bud that constantly glows with power. The fusion will end if Calyrex loses power or the Rein of Unity are used again.

If Calyrex is Shiny, its forms will also be Shiny, though this only alters the coloration of Calyrex's body, not the bodies of Glastrier or Spectrier. The coloration of Glastrier or Spectrier does not affect the coloration of Calyrex's forms when combined.

Tandemaus and Maushold

Tandemaus consists of a pair of Pokémon. When it evolves into Maushold, one or two babies appear.


Wugtrio was once considered to be a regional form of Dugtrio, before it was found to be a completely different Pokémon. Like Dugtrio, it has three bodies, two more than it had as a Wiglett.

Dipplin and Hydrapple

Dipplin and Hydrapple consist of two wyrms and seven syrpents, respectively. Dipplin's eyes and horn belong the "fore-wyrm" while its tail belongs to the "core-wyrm". Hydrapple's middle syrpent is the commander, the four around the apple are mostly hidden and the last two ones serve as Hydrapple's tails. It is not stated if these creatures are themselves considered Pokémon.

Similar examples

In the core series games

A few unique Pokémon fusions debuted in the core series games, later appearing in various game adaptations such as the anime and manga.

Various Pokémon and Bill

In the Kanto-based games, Bill is seen in his Sea Cottage fused with a Pokémon, temporarily taking on its appearance while retaining the ability to talk. He asks the player to help him use the Cell Separation System to turn back to normal.

The specific Pokémon that Bill fuses with differs across media. In Generation I, he is fused with an unknown Pokémon. In Pokémon FireRed and LeafGreen, he is fused with a Clefairy. In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, he is fused with a Nidorino. In the Pokémon Adventures manga, he is fused with a Rattata. In the Pokémon Zensho manga, he is mixed with a Nidoran♂. In the anime, he is simply trapped in a Kabuto costume.

Nihilego and Lusamine

Nihilego taking control of a host

Nihilego is an Ultra Beast who hails from the Ultra Deep Sea. Dubbed as UB-01 Symbiont, Nihilego possesses the ability to latch onto a host in order to protect itself. It can exaggerate the host's own capabilities and emotions by injecting them with a neurotoxin, stimulating their excitement and disabling their inhibition. As such, Nihilego can take control of its host, whether they are a person or Pokémon, and make them think improperly for themselves. Guzma, a victim of being a Nihilego's host, claims that this is quite unpleasant for the host. He states it felt as if his mind and body were in control of their own as if he had become somebody else, leaving his own consciousness to feel nothing but fear.

During the climax of Pokémon Sun and Moon, Aether President Lusamine had sent herself to Ultra Space, a location inhabited entirely by Nihilego. After confrontation with her daughter, Lusamine calls a Nihilego with a Beast Ball, and willingly allowed Nihilego to latch onto her head and battle the player. While in most scenarios, Nihilego will simply latch onto their hosts' head, latching onto Lusamine had caused a sudden transformation in both her and the Nihilego, giving the two a black and purple color scheme. When fused, Nihilego grows much larger, enveloping its host inside its bell, and losing the star-like pattern. Nihilego's tentacles change shape with the four in the front gaining fingers, which Lusamine has control over, including being able to use Poké Balls. Like normal Nihilego, this fused state has caused Lusamine to be violent and aggressive, lashing out towards Lillie and the player, who had been protected by Nebby. Nebby had split Nihilego from its host, returning the two to their normal states visually. This form and fusion has no official name; however, internally, it is called MOTHERBEAST.

While no longer attached to the Ultra Beast, the neurotoxins remained in Lusamine's body, causing her to fall ill. She had fallen unconscious after the events that took place. The cause of this fate is unknown, however Lillie and Wicke had narrowed down three possibilities: the amount of toxins that Nihilego had injected into Lusamine, the overwhelming amounts of Z-Power surrounding her and her Pokémon, or the stress of the fusion with Nihilego itself. Worried for her mother's health and safety, Lillie had left Alola to go to Kanto with Lusamine and seek Bill, who had previously fused with a Pokémon himself, to see if he could remove the remaining neurotoxins from her body.

Nihilego's parasitic behavior is also shown in multiple media. The fusion between Lusamine and Nihilego also appears in Pokémon the Series: Sun & Moon and Pokémon Adventures.

Spoiler warning: this article may contain major plot or ending details.

In Detective Pikachu Returns, it is revealed that Mewtwo had saved Harry Goodman's life by transferring his mind into his Pikachu's body. During the climax of the game, Charles Merloch fuses his mind with the body of a Deoxys. The fusion is eventually undone by Pikachu, restoring Merloch's mind to his body. Harry's mind is also returned to his own body shortly afterwards by Mewtwo.

In the anime


In The Ghost of Maiden's Peak, a Gastly, who had the ability to create illusions that were tangible enough to attack people, created a fusion of Venusaur and Blastoise to scare Bulbasaur and Squirtle, calling it a "Venustoise" (Japanese: フシギックス Fushigix).

Mismagius and Rayquaza

In Malice in Wonderland!, a real Mismagius merged with a Rayquaza illusion it created, giving Rayquaza the color palette and some features of Mismagius. It then attacked Ash and his friends.

Pokémon RéBURST

Main article: Burst

Burst is a special technique in Pokémon RéBURST that allows a human to combine with a Pokémon, gaining its powers and immunities while increasing the user's physical and defensive strengths.

In order for one to perform Burst, they will need a special item known as a Burst Heart, a small, pocket-sized jewel that actually holds a Pokémon inside of it, sealed so that its power can be used by anyone wishing to fuse with it. Once Burst is activated, the user will have their physical traits increased greatly. Whatever abilities the user will get depends on the type of Pokémon used to combine. Additionally, a person can be sent inside of their Burst Heart in order to better connect with the Pokémon inside.

For a list of known Burst Warriors, see here.

In POKÉMON Detective Pikachu

During the climax of POKÉMON Detective Pikachu, Howard Clifford merges his mind into the body of Mewtwo. He then uses Mewtwo's powers to fuse the bodies of the people of Ryme City with their partner Pokémon, including fusing Lucy Stevens with her Psyduck and Lieutenant Hide Yoshida with his Snubbull. Eventually, the neural link headband is removed from Howard Clifford's head, causing his mind to return to his body. Mewtwo, now free, separates the people and Pokémon. At the end of the film, it is revealed that Detective Pikachu is a fusion of Harry Goodman and his Pikachu, created by Mewtwo to save Harry's life.

In the fandom


Splicing is the process of taking existing Pokémon sprites and combining them to create new and unique sprites. These sprites may represent literal fusions of the component Pokémon, or other ideas, such as entirely original Pokémon or altered versions of existing Pokémon. These sprites may be created as fan art or to be added to fan games, as well as to be shared in online communities and forums.
