its really simpel.. press the Z button to transform, and the X button to DEtransform. that is transforming back to normal.. you need a sertan Powerlevel to transform so goku need 1.750.000 , and gohan 1.000.000 and trunks 1.000.000. vegeta needs 2.000.000. and you see those in character menu.. then when you got that powerlevel press the Z button ( Z button is default. ) .. how to get a higer powerlevel? kill people. kick them whit melee or blasts. or wish for more power whit the dragon
