Ken Shamrock – $1.5 Million
Even though Ken Shamrock joined WWF and TNA, he was a lot more successful as a mixed martial artist. Did you know that he was the first fighter to claim victory at a UFC Super-Fight Championship? His two sons also tried to make it in the world of MMA, but Ryan has not been very successful. On the other hand, Sean had no choice but to quit after a cancer diagnosis.
Owen Hart
Born into a wrestling family, Owen Hart was guaranteed to be good at it as well. He was declared the winner of the WWF European Championship, the WWF World Tag Team Championship, and the WWF Intercontinental Championship. Sadly, he died in a freak accident in 1999. While he was being lowered into the ring, he fell to his death. It had been a quick and painless death, apparently. There are people who claim that he continues to haunt the ring.
