14 Most Savage Celebrity Martial Artists

Ashton Kutcher might not be the most intimidating person this list, especially since he's mostly known for making major business moves and starring in terrible TV comedies. However, when he's not doing the things he's most famous for, he's usually pursuing his hobby of Brazilian jiu-jitsu

As fellow celebrity and martial art fanatic Joe Rogan explains in the video above, Kutcher's jiu-jitsu instructor is Rigan Machado, who in jiu-jitsu circles is a major legend alongside his brother, Jean Jacques Machado. While there doesn't seem to be any footage of Kutcher wrapping up any of his opponents like a pretzel, the fact that he's got this far in what many consider to be the hardest black belt to earn goes to show that he's certainly not one to be taken lightly.
