11. Eric ‘Butterbean’ Esch
‘Butterbean’ is a true combat sports cult hero. This massive individual is a former boxer, kickboxer, and MMA fighter who competed in the heavyweight and super heavyweight divisions. You would not want to be responsible for feeding him. At his heaviest, Esch weighed an enormous 421 lbs. But he definitely wasn’t just a big target.

This larger-than-life fighter gained his nickname after his ridiculous diet for the Toughman competition. ‘Butterbean’ was an IBA Super-Heavyweight champion. Not only that, but he also fought in Japan for the likes of PRIDE and K-1. He was around for a long time, with a ridiculous 136 professional fights in all sports.
