Squirtle is a surprisingly powerful fighter and especially once he transforms into Blastoise. Bowser may have his flames at the ready, but they wont do all that much to someone like Squirtle. Squirtle would speedblitz his way to victory. Bowser just doesn’t have the speed feats or long range techniques necessary for a victory in this round. Squirtle wins.
