Ken Shamrock
Known as the first-ever fighter to have earned a UFC Superfight Championship title after competing in both the WWF and TNA, Ken Shamrock left the wrestling scene to pursue a martial arts career in which he also had a successful run. His two sons also appeared in the MMA, but not as successful as him as one did not have many wins, while the other had to quit due to one of his kidneys being removed due to cancer.
