Chris Jericho
Like many wrestlers, Chris Jericho began in the WWE and had a fruitful career through the 1990s. But as time went by, he shifted to another organization, Japan Pro-Wrestling, where he’s still active even now. Throughout his WWE years, Chris won a few titles including the World Heavyweight Championship. Although still competing today, he was now an investor and one of the founders of D1 Sports Training and Therapy.
Ken Shamrock
Ken Shamrock would be the first boxer to win the UFC Superfight Championship belt since fighting in both the WWF and TNA. Nevertheless, he left pro wrestling to start a career in martial arts, where he has had a successful career. Shamrock’s two sons appeared in the MMA but were not as successful as one had not had many wins, and the other had to stop because one of his kidneys had been removed due to cancer.
