Fusion (フュージョン, Fyūjon) is the process of merging two separate beings into one to combine their attributes, from strength and speed to reflexes, intelligence, and wisdom. When properly fused, the single being created has an astounding level of power, far beyond what either fusees would have had individually. So far, it has been shown that there are at least six different ways to fuse.


Piccolo fusing with Kami.

Sync (同期, Dōki) is the first type of Fusion that appears in the series. A special technique unique to the Namekians, it is more of an Absorption than a Fusion as one Namekian absorbs the energy, strength, memories, and intelligence or thought pattern of another. Both participants must willingly consent to fuse in this manner and usually the pair agrees to the stronger of the two to serve their body as the host. The agreed host places his hand over the chest of the other and through unknown thoughts, a flash merges them.

This technique was used twice in the series. In both cases, Piccolo took the role of the absorber. The first time, Piccolo synced Nail, the last Warrior, before fighting against Freeza. The second time, Piccolo absorbed Kami before fighting against Imperfect Cell. On both occasions, the new Piccolo was strong enough to match or possibly beat the current villain. In Dragon Ball Z: Supersonic Warriors, Piccolo absorbed Piccolo Daimao (making him truly complete). The Assimilation is enough to increase his strength to the point of being equal with Super Boo.

The largest difference with this type is that once completed, it cannot be undone even by methods that can undo a Potara Fusion (such as being absorbed into Majin Boo's body, evidenced by the fact that Piccolo was found inside Super Boo's body, but not Nail or Kami). Both the host and his partner have separate consciences, where the host has control of the body while the partner just watches from inside the body, though they are capable of talking with the host's consent. Also, the non-host still retains his conscience; during his fight with Imperfect Cell, Piccolo gave Kami credit for coming up with the idea of playing possum in order to extract information from Cell. It is also possible to merge with more than two Namekians, though it seems the non-host ceases to exist as a body, seeing as how the Dragon Balls turned to stone when Kami and Piccolo merged.

It is named Yūgō (融合, Yūgō) in Dragon Ball: Daizenshū 7.

Fusion Dance

The Fusion Dance is a technique developed by an alien species called the Metamorans which Son Goku learned in the Next World. It was first introduced when the threat of Majin Buu emerged. The dance results in a completely new merged being with characteristics from both mergers. The newly fused body is dressed in Metamoran attire; a dark colored vest lined with light colored linen, white pants with a cloth belt and boots. The Fusion only lasts 30 minutes. There are certain requirements to the Fusion Dance as opposed to the Potara Earring fusion. The mergers have to be of the same species, i.e. two Saiyans, as well as having equal power and similar height.

Each character stands six paces from each other, side to side. They hold their arms out so each person's arms point away from their partner, palms open and facing forwards. While saying, "Fuuuu..." each person shuffles their feet sideways towards their partner. Both people must take exactly three steps at this time. While doing so, each person swings both arms over their head so each of the two sets of arms point to their partner's. Then, while saying, "sion..." each person swings their arms across their body, turning them so their palm faces the floor and closing their fists. At the same time, they must bring outer leg up so it is at a right angle, with their shin facing their partner and their foot level with their knee. Finally, each person shouts "Ha!" and leans their torso over so it is slanted towards their partner. They bring their arms up over their head so they point "upwards" (in relation to themselves) with their index fingers out. They must then fully extend their outer legs. At this point each person's fingers should touch their partner's fingers. If both characters do this exactly right, the fusion will be successful.

They must always mirror the other merger otherwise would result in a faulty version. The whole process is rather short despite the long description. The limits of the Fusion Dance is very great in comparison to others. For instance, the fusion only lasts 30 minutes at most and that can be cut down further to as little as about five minutes if too much power is needed to sustain the form or damage is taken in. Another weakness is its unreliability. Suppose in combat when you and your partner decide to fuse and your partner fails to mirror you, you would most probably find oneself desperately clinging to life as you both wait for the 30 minutes to end, as you result in an extremely weak obese version of the fusion with not even the ability to scamper around without catching his breath, or a sickly, skinny old version that can barely stand on his own two feet.

However, if the fusion does succeed, the new merged being will find the results are well worth the risks, though initially, to access advanced states such as Super Saiyan, the two fusees must first be transformed into the state prior to performing the dance, though with training they will learn the ability to transform even whilst fused, at will. The Fusion Dance creates a being that resembles both people pre-Fusion, but can have a dominant side in both their behavior or appearance. Once the fusion is successful and the fusion expires, the two fusees will not find themselves able to fuse again without an hourly resting period, as shown by Goten and Trunks' inability to resume their Gotenks state after they separated against Super Buu, which did not happen when the fusion failed and the two assumed their fat and skinny states. However, in Yo! Son Goku and His Friends Return!!, Goten and Trunks somehow de-fused themselves after accidentally fusing into Fat Gotenks, contradicting this.

In the manga, the only characters to use the Fusion Dance are Kid Trunks and Son Goten. Their first attempt results in a fat Gotenks, the second in an old Gotenks, but the third attempt produces the true Gotenks, who fights Majin Boo. He later fights against Super Boo in the Hyperbolic Time Chamber and again, as Super Saiyan 3, on Kami's Lookout. This quick unlocking of the state and its usage however shortened the time that they could stay fused tremendously.

In Fusion Reborn, Goku persuades Vegeta to do the Fusion Dance with him to form Gogeta and destroy Janemba. Their first attempt, however, results in a fat Gogeta named Veku, as Vegeta had his fist clenched when his finger was supposed to be extended, from just having seen the dance from Goku. The Fusion Dance was also used in Dragon Ball GT, when Goku and Vegeta fused into Super Saiyan 4 Gogeta to fight Omega Shen Long, though the fusion wore off before Gogeta could destroy him.

In Dragon Ball Z: Budokai 2, Yamucha and Tenshinhan can do the Fusion Dance and become Tiencha. This and all "what if Fusions" were strangely removed from its acclaimed sequel, Budokai 3.

Fusions can also be terminated by a sufficiently powerful force. Goten and Trunks fused to fight Hirudegarn in Wrath of the Dragon, and in the battle the monster hit Gotenks with sufficient force to seperate Goten and Trunks far before the 30 minute time limit had been reached.

Potara Fusion


A Potara Fusion (ポタラ 合体, Potara Gattai) was Fusion by use of the Potara Earrings that the Kaioshins normally wore. These earrings combined both users into a new being with complete attributes in the final product all the way down to their clothes. Supposedly, this Fusion would allow for advanced transformation states such as Super Saiyan forms to be accessed even after the Fusion, though the Old Kai commented that they could technically merge whilst at full power in the state, but it would shorten their lifetime significantly from being unable to fall out of the form as merged beings stays together forever and will never be able to break whether the two like it or not. The only exception was when Vegetto was absorbed into Super Boo's body, which had a completely different environment from the rest of the universe, its magical qualities dissolving the Fusion, which does not seem to affect the Fusion of Goten and Trunks into Gotenks.

Using the earrings is very simple, in comparison to the fusion dance. Each person puts on the earrings on the opposite ear of their partner. The orb on the earring glows and both users are thrown together. The new being emerges glowing in green light with the earrings still on each of the two ears.

So far in the Dragon Ball universe, only three of these fusions are accounted for: One with Vegeta and Goku to make Vegito, one with Kibito and the Eastern Supreme Kai to make Kibito Kai and another with Old Kaioshin with an Old Witch. All of these transformations gave the new merged being with powers from both mergers amplified beyond the Namekian version and the Fusion Dance, so much that a mere Super Saiyan Vegito found himself completely dominating against Super Buu with Gohan, Goten, Trunks, and Piccolo all absorbed into his body.

It would seem that in a fusion with a Kaioshin, the Kaioshin tends to be dominant. For example, when Old Kaioshin (who looked young at the time) accidentally fused with the witch, the only real changes to him were his age, his voice (which only sounds older), and the witch's magic powers. Also, with Kibitokai, the only real changes were his hair style (he adopted Kibito's hair), his clothing (he adopted Kibito's red Kaioshin uniform), and his abilities (he gained all of Kibito's and East Kaioshin's abilities). The way he looked back at Majin Buu's history, he is clearly more Supreme Kai than Kibito.

Another fact is that when someone uses the earrings, the fused being will often have a cross between the clothes of the two users (Vegito) or just one set worn by one of the users (Elder Kai, Kibito Kai) instead of the clothes worn by the Fusion Dance warriors.

It is possible that when two people fuse using the earrings, as opposed to the Fusion Dance, their voice sounds like one voice instead of two. However, in the FUNimation dub, Vegetto sounds like Goku and Vegeta speaking at once, much like Gotenks (which makes more sense). This is strictly in the FUNimation dub, however, as in the Ocean Group dub Vegito has one voice instead of two. The Japanese dub also has Vegito being voiced by the voice actor for both Goku and Vegeta, however, though neither the old Kai nor Kibito Kai had two voices.

Absorption is a bit different form of Fusion since it usually involves the consumption of an individual as opposed to a sharing of power. This is done by Cell and Buu. Cell uses his scorpion-like tail to absorb a helpless victim, while Buu uses his flesh to do the job. A similar technique is used by Naturon Shenron to take control of a body and multiply its natural abilities for his own destructive use. Artificial Human No. 19 and No. 20 also employ a form of absorption, though theirs only absorbs energy from a target, rather than the target's entire body.

Machine Mutant Fusion

The Machine Mutants Nezi, Ribet, Bizu, and Natt fused to become the Sigma Force Cannon in Dragon Ball GT. It was presented in such a way that suggested it was a racial ability of all Machine Mutants.

Later, during the Super 17 Saga, the Hell Fighter No. 17 fused with Artificial Human No. 17 to become Super No. 17.

Hypothetical fusions

Tiencha in Budokai 2.
The hypothetical Fusion between Goku and Dende as imagined by Goku.
The Fusion between Goku and Hercule as imagined by Goku. Also playable in Dragon Ball Z: Budokai 2.

Gotan is a Potara Fusion between Son Goku and Mister Satan (known as Gokule in non-Japanese releases of the game, using Satan's name in the edited FUNimation dub reversioning, Hercule). Gotan is actually based upon a scene from the anime where Goku has to choose with whom to fuse with before Vegeta arrives (thus forming Vegito, instead). The choices included Dende (which would form Denderotto) and Satan (which would form Gotan). A Piccolo-Goku Fusion was made imaginary when Goku and Dende demonstrated the motions for Fusion.

In Dragon Ball Z: Budokai, there was one quick Fusion in a what if sequence wherein Cell attempted to absorb Artificial Human No. 18, only to have Kuririn shove her out of the way. This resulted in Cellin, a Cell who took on the stature of a Cell Junior body with Kuririn's black and orange color scheme, Xiaolin forehead dots, and the Turtle School symbol across his back.

The Budokai series of video games features two imaginary (what if) fusions. Yamhan (Tiencha in non-Japanese releases) is a Fusion Dance between Tenshinhan and Yamucha. In a brief scene in the bonus stage of Z World (based on another of Toriyama's works, Neko Majin Z) featured exclusively in the Japanese version of Budokai 2, Goku meets Tien and Yamcha (who then fuse together) on the gameplay board.

Budokai 2 also featured imaginary absorptions for Super Boo. In the game, Super Boo could use his absorption technique as a normal attack capsule. If successful, he absorbed a random character and took on a new appearance and some of that character's attacks. While he could use his canon absorptions of Gohan and Gotenks, he could also absorb Freeza (giving him Freeza's purple studs and Death Ball finisher), Cell (giving him Cell's black chest stud and green spots as well as the Genki Dama), Vegeta (giving him Vegeta's Buu Saga blue muscle shirt and Final Flash attack), and a two-for-one absorption of Tenshinhan and Yamucha (giving him Tenshinhan's Cell Saga green sash, Yamucha's scars, and both Tenshinhan's Volleyball Fist and Yamucha's Sōkidan attack). Super Boo never absorbed these characters in the original manga or anime.

Piccolo used the Fusion Dance to fuse with Dr. Mashirito, a villain from Dr. Slump (also written by Akira Toriyama), in a "tag attack" in Jump Super Stars. This unnamed Fusion of Piccolo and Dr. Mashirito yelled at his opponent in order to deal damage.

In 1995, Weekly Shonen Jump (Issue #13) began a contest where fans were encouraged to come up with their own "dream fusions". To get fans started, Akira Toriyama drew a picture of a theoretical fusion of Piccolo and Kuririn. The result was a small warrior featuring Piccolo's ears and Kuririn's body structure. Written in the text is the explanation "Piccolo + Kuririn?! Could his name be 'PIRIRIN'?!"

Names of fused characters

Goku mistakenly calls the merging of Piccolo and Kami "Kamiccolo", while Piccolo mistakenly calls the fusion of Son Goten and Trunks "Trunkten". The fusion of Supreme Kai and Kibito is not given a new Fusion name (and also does not speak with the traditional dual-voices in the anime); this character is called both Kibitoshin and Kibito Kai in official Japanese and American merchandise after the series' end.

Within the North American releases of the series, a major inconsistency is held with the name of Goku and Vegeta's Potara Earring Fusion, Vegetto. With both FUNimation's and Viz's logical localization of Kakarotto to Kakarot/Kakarrot, the emphasized "to" syllable from the original romanized spelling makes little sense to include in a localized fusion-character's name. FUNimation's original spelling of the name can be seen as Vegetto (in old merchandise such as the PlayStation video game Final Bout), and later standardized to Vegito; no attempt to explain the name is over-analyzed in the English dub's dialogue. On the other hand, to explain the origin of the name, Viz's translation of the manga renames the fused character Vegerot (pulling in their localization of Kakarrot).

Fused warriors often tend to refer to their fusees in third person (ex: Gogeta saying, "I am neither Goku nor Vegeta, I am the instrument of your destruction!") possibly because they have their own personalities and consider themselves a completely different being. It could also be possible that Vegito, since his personality appears to take a bit more after Vegeta's, thinks of Goku the same way Vegeta does. However, Vegito obviously retains feelings for both Goku and Vegeta's families.


  • Vegeta seemed very hesitant to fuse with Goku during the battle with Buu, yet finally agreed to fuse using the Potara Earrings which was supposed to be a permanent fusion rather than do the Fusion Dance which would have only been a 30 minute fusion.
  • When Goten and Trunks did the Fusion Dance and became Fat Gotenks they said that they could not remember anything, but when they fused and became a Super Saiyan 3 and then defused Trunks remembered becoming a Super Saiyan 3.
