Some people may now when you go to challenge or zbattle u can choose ur character by going up and down but if u go left or right u can choose there levels (1 2 3) u can change buu into evil form, goku super sayian, freeza mechanical, and vegeta super sayian, and gohan into his older form by doing this and when you do this to almost every character its moves will get better to. and when u press a and b at the same time (not with holding L or R) u will do a special move this adavnces as well thru the levels BYE _BYE SYANARA ADIOS SEE YA LATER "ILL BE BACK" LOL
