Name:
Gotenks
Characters
combined:
Goten, Trunks
Gotenks
was formed when Goten and Trunks did the fusion dance. Gotenks
is a powerful fighter but could not really show his full
potential due to the fact that he is an arrogant person. After
first being formed he heads over to fight Buu where he gets
beaten up. Gotenks makes most of his moves with stupid names
like 'Rolling Thunder Punch' and 'Ultra Buu Buu Volley Ball etc.
He was able to reach SSJ3 but he was also absorbed by Buu. After
DBZ finished we no longer saw Gotenks any more.
Name:
Vegetto
Characters
Combined: Vegeta, Goku
Vegetto
was formed when Goku and Vegeta used the Potarra Earings. He is
probably one of the most powerful characters in DBZ since the
two best fighters are combined. Originally Goku was supposed to
fuse with Gohan but since he was absorbed by buu Goku had to
fuse with Vegeta. They kicked buu's ass pretty badly and got
absorbed purposely to save Gohan, Trunks, Goten, and Piccolo.
Name:
Gogeta
Characters Combined: Vegeta, Goku
Gogeta
was formed when Goku and vegeta did the fusion dance. Gogeta is
even more powerful than Vegetto. He was first seen in movie 12
to battle Janemba. At first Vegeta screwed up on the fusion
dance and they transformed into fat Gogeta. They got beaten up
pretty badly but 30 minutes later the fusion wore off and they
did it right and kicked janembas ass. Gogeta also appeared in GT
but for one episode only
I think.
