I know one martial art that can kick everyone asses... its MUAY THAI(BORAN)
Muay or muay-boran,,, it's the same thing actually, but Boran include grappling in training and locks, used alot from the old war of Siam.
Muay train mostly for thier strenght for the basic kicks, punch, elbow and knees, and how to take a beat ofcourse. It's like facing a OokTree with gloves but sometimes they also train grapplings for selfdefene but not in the sports. Some just don't train at all about grapplings that they focus more on the strenght and the bones. I mean not many servive a real MuayThai kick or elbow with one blow(if you are unlucky). But that is how it is, what this art is good at - kick, knees, and elbows and sometimes on the punches. That's why they are the god of all arts.
