How do you fuse in Dragon Ball Z budikai tenkaichi?

Answer 1

first of all the people fusing have to both be in there normal form they cant be super sayan it will tell u on the command list who that person(if any) can fuse with. i think the only fusion characters are trunks(kid form), goten,goku,and vegeta another thing is that u need 3-5 blast stocks to preform it (depending on what fusion)and the person your fusing with has to be the person on standby for instance if u wanted gogeta u would have to be playing as goku or vegeta and have the other person(whicever one u arent)on standby
