#3 Bret Hart
Bret Hart is known as the best there is, the best there was and the best there ever will be, and rightly so.
A technical wizard in the ring, Hart's ability was matched by his character, working crowds into a frenzy as both a face and as a heel.
In 2016, Hart made a public post where he announced his cancer, a shocking blow to all his fans.
Ever-resilient though, Hart battled the disease, revealing in March that year that he had beaten prostate cancer thanks to regular checkups.
Though he now has to have checkups every three months, this is a small price to pay for the legendary star, who recently received his second induction into the WWE Hall of Fame.
Nowadays, Hart is much healthier, and the Hitman makes occasional appearances for WWE.
