To win easily, just press Square then X. You will punch, then deliver a heavy blow leaving your opponent defenseless for a short time. Note: Sometimes very good fighters, for example Android #15 or #12 in Ultimate Battle mode, will break this combo. If your character is fast enough (try increasing the speed stat on your character's Evolution Z to help) and your opponent is a big character that will not be affected by normal punches and kicks or normal Ki blasts, you can land up to one attack from your character's full combo ability (the maximum is about five), then press X. You can get 99 hits if you are skilled enough. It will not count any more after that, but the damage will still be rising.
