yea so, trunks has one normal atack, burning atack, and wolf fang fist is right click on melee, hold it down and it charges. if you wanted to activate it, before you swoop, hold down right click and it comes up with a charge bar, the same rules aplsay, when it gets to the strength you want it, swoop into the person you want to hhit it with and caboom. it hits them, it isn't exactly strong, but it is better than any other normal melee atack and sword atack (unless you are adding a slash atack). and his kamahama is not very weak, it isn't as strong as gokus as goku has done every possible aspect of it, it is about three quaters of the strength of gokus camhama. and his spirit ball is the strength of a special beam cannon fully powered. he is kwl and he used solar flare so he could have that, already he has more attacks than trunks so his stats would be;
speed; 100
health; 100
starting powerlevel; 650
transformation (power up and change of clothes) ; 3,000,150
pretty good now.
