So I'm re-reading the bio's while writing my post (to make sure I get the details right), and I noticed that Kitsune's punching force is only half a ton. Professional MMA fighters can hit more than twice that hard. If the goal was to make kitsune slightly more potent than a human, I recommend we allow him to up the punching power to 2 tons and the kicking power to 3. He should also probably double the iron tails impact force resistance (if not triple it), as one mundane punch from Ahven could currently break the ability and force the tails to revert, and he's not even the boss.
