ah cmon...brolli = 3 movies...thats almost a saga...and his moves would look uber with the effects in ESF, specially his energy ball =) and hes got transformations to go along with the others...normal brolli, ssj, and lssj so balance would be just fine, just make his PL around buu's starting PL and make his transformation PL higher than the others
back to topic...ya a good skin of brolli would be good, ive only seen 1 worthy of acctually looking at, hes a hard char to model tho, no shirt so you have to show all the features
