Ah, with Jigsaw Frank just redisfigures him out of spite everytime he manages to get his face fixed.
Still, he's faired better than Barracuda (stabbed in an eye, fingers cut off on one hand, shot in the face and left to be eaten by sharks, Frank biting a hole in his cheek, Frank connecting his junk to a car battery, his nose being cut off, one arm being hacked off with an axe and the hand of the other arm cut off before finally being shot repeatedly in the head).
