The Mishima family is immortal you fool.Kazuya is way to powerful with the devil gene.Did you see the opening for Tekken 5 Kazuya and Heihachi tore through like 30 metal Jack robots like wet tissue paper.Heihachi blown up with a bomb that knocked him 2 miles away and the bomb was right on top of him.Kazuya at the age of 12 survived being thrown of a mountain and climbed back up.He also survived 2 years in a volcano.Jin (Kazuya's son) survived being shot up by M4's then being shot in the forehead with a 24 magnum revolver then got up and killed two guards then through Heihachi through a wall.(as Heihachi said to Raven the Mishima's are immortal you fool!)Batman and Batgirl have little to no chance.
