There is a high school wrestler (real, scholastic wrestling, not WWE three-count fake wrestling) with both arms cut off above the elbow and both legs chopped off above the knee. So far he has had, incredibly, a pretty good season. He gets no special handicap.
Owen hart was supposed to perform a high wire antic at some WWE show but the rope snapped and he died from the fall.
Brock lesnar had a fight with WWE and split up with them. He now wrestles in Japan and is the champion out there.
