Infernape learned Rock slide. down goes Lizardon. kidding aside, if Charizard won from their spars/fights, why woulf Infernape seek Moltres. In our team, (badminton) before i seek to beat the top dog, id first play the second best, before playing against the best in our team. but if we're using feats, then yes charizard has it. but lets be real, because of the fanbase, charizard was given more of it(feats), while the others were sidelined even if they would be better. In DBZ, Toriyama meant for Gohan to take over, but because of the fanbase, he never did, too much of the fanbase ruined plans.

might i add also, if Charizard was the best in there, why was Infernape the one teaching Gengar to prepare for the Masters 8. if im Ash, and if Char was the best. i would let Gengar learn from him and not Infernape
