Before becoming an established heavyweight boxer, Dillian Whyte ventured into two other combative realms including a successful stint in kickboxing.
He was a professional kickboxer, becoming a two-time British heavyweight kickboxing champion - so certainly no slouch.
And on Friday night old footage of Whyte competing a Muay-Thai fight emerged on Twitter.
As you can see in the video below, Whyte held nothing back in the brutal scrap against Will Riva.
In Muay Thai, punches, kicks, knees and elbows can all be thrown and it turns out Whyte is pretty devastating when attacking with any part of his limbs.
The fight eventually came to a close when Whyte landed a big knee clean to Riva's face which sent him flying backwards.
In case you needed any further prove of the Body Snatcher's pure love of fighting that was it, he was certainly in his element even then.
Of course, these days Whyte is better known for the damage he can cause using just his fists.
He made his professional boxing debut in 2011, and has since compiled an impressive 25-1 record, with that one defeat coming to world champion Anthony Joshua.
And after knocking out Dereck Chisora just before Christmas he's now got his heart set on a rematch with Joshua.
"It's a good fight, a good champion," he said. "I believe this time around I'll knock him out, because I'll take the fight to him. Last time I sat back and waited, I was trying to box, and trying to wait for him to get tired.
"This time I'll take the fight to him and I know I've just got to hit him once. I proved that already on two separate occasions, and this time I'm in better shape, physically I'm stronger. More boxing IQ, better speed, everything."
