10. J.R. Martinez
We're guessing most of the DWTS audience is not going to be familiar with J.R. Martinez's story. The motivational speaker turned actor is a former U.S. Army infantryman who was injured while fighting in Iraq in 2003. He suffered burns over more than 40 percent of his body and has undergone 32 surgeries since then, including skin grafts and reconstructive procedures. He currently plays Brot Monroe on All My Children.
