I'm going to give the nod to Perry Saturn.
In 2004 still wrestling after a release from WWF in 2002, Saturn would have to face one of his hardest journeys back to the ring yet. He was driving his girlfriend to work when he saw two men trying to rape a girl. He wasted no time stepping out of his car and coming to the rescue. He fought with the men and saved the girl but it wasn't all good news. Saturn felt a burning sensation in his neck; he had been shot 3 times there.
He now has a steel plate along with three stainless steel screws where his C-5, C-6 and C-7 vertebrae are. Now under these conditions alot of men would call it quits but not Saturn. Against all odds he began training extensively to get back into the ring after his huge injury. How incredible is that? After 3 gun shots in the neck not only is he standing he's ready to get back into the ring and continue what he loves to do.
And let's not forget Ric Flair, who survived a plane crash.
