i know this has been done before but i haven't seen it on the topic list lately so i'll start it up again. all you do is create a name, the people the fusion consists of, 1 ultimate move and how many forms they have, as in super saiyan,etc.
Fused: Piccolo and Gohan
Move: special masenko cannon (he shoots it like a masenko but the masenko beam has coils moving around it like the special beam cannon)
Forms: super saiyan, super saiyan 2
