Goku first learned about fusion while in the
land of the dead. (For he was dead himself.) Fusion is what to fighters of
the same species, about same stature, and about same powerlevel perform to
become one being whos powerlevel is alot stronger than before. It is where
the two fighters fly up into the air, and copy each others moves like a
mirror in a sort of ritual dance. It lasts for a half hour, and cannot be
undone until the half hour is over, then the fusion becomes unpermanant
anyway. And after unfused, you cannot perform the fusion dance for an
hour. If one of the fighters even does one tiny mistake, the whole fusion
can turn out wierd. Like the fused fighter can be too fat or too skinny.
Namics can fuse also. These fusions are permanant. Piccolo fuses with Nail
and Kommie.
Gogeta and Gotenks
Gogeta is formed by
Goku and Vegeta. They can go up to SSJ4 Gogeta. This stage is
very powerful, but not their strongest fusion, as you
will soon learn. Gotenks is formed by Goten and Trunks. They can go up to
SSJ3. They originally can go up to SSJ2, but Gotenks by himself went SSJ3.
This stage is pretty powerful also.
Vegetto
Vegetto is a special fusion between Goku and
Vegeta. Although Gogetas personality is mostly Gokus, Vegettos isnt, and
he's cocky, but he has a reason to be. Vegetto is formed with a special
dance which involves two earings, which they both have to ware on opposite
ears. Vegetto is legendary, and his strength is unmatched. He can only go
up to Super Saiyan. But in regular form, he can beat Buu, a very powerful
alien who he ends up beating SSJ. I'm not sure if he went SSJ for kicks or
what, but he's very powerful. Unlike normal fusing, this fusion is
permanant. Which lies unexplained in the fact that he later turns back to
Goku and Vegeta.
