Ken Shamrock
Net Worth: $1.5 Million
Ken Shamrock is the first-ever fighter to have earned a UFC Superfight Championship title after competing in both the WWF and TNA. However, he left professional wrestling to pursue a career in martial arts, where he also had a successful journey.
Shamrock’s two sons made appearances in the MMA but have not been so successful as one didn’t have many victories, and the other had to quit too due to one of his kidneys being removed due to cancer.
