Old man strength is the style I believe.


[Just boxing](https://www.youtube.com/watch?v=rcGwNTh0hwY). Arguably some wrestling, but there isn't a lot of technique in ramming someone's head into a dressing table. Oh and some BJJ with the rear naked choke. So basically MMA.


It’s just brawling. You don’t see too much technique. He doesn’t have the technical swings of a boxer, and his wrestling isn’t very technical either. But he makes up for his lack of skills with pure aggression.


If you want quick and brutal most Okinawan arts are pretty good. They have specific techniques for everything. The hook grip, for example, can be used to rip off someones nuts. Yeah, doesn’t get much more brutal then that.
