Flash Punch Combo is a move used by Jinpachi Mishima since his introduction in Tekken 5
Unlike the normal 3 hit combo version, Jinpachi only comprises of two hits though he can delay the last hit like with the other Mishimas. In Tekken Tag Tournament 2, however, this ability to delay the second hit was removed, but Jinpachi's Flash Punch Combo will wall splat an opponent, a property that was removed for the other versions in Tekken 6: Bloodline Rebellion.
