-Goku's
Fusion's
Fusion names:Vegitto,
Gogeta
How:
Vegitto:This was done using the potara earings Goku originally wanted to fuse
with Gohan but Gohan got absorbed by buu, when everything seemed dull Vegeta
showed up and Fused with Goku. Each character puts an earing on seperate ears.
Gogeta:This was performed by using the Fusion Dance technique, this occurs whilst
fighting Janemba, Goku ssj 3 is no match for Janemba so him and Vegeta fuse
to form Gogeta.
