The UFC is full of devastating masters of combat who are dangerous standing, on the ground or in the clinch, and this capability to inflict punishment anywhere is downright scary.
Some fighters, though, are as physically terrifying as their skill sets would indicate, and for that I've compiled a list of the top 10 UFC fighters of all time who could make Chuck Norris quiver with fear without even raising a fist.
Jeff Monson has been in and out of the UFC throughout his MMA career and has a modest 4-3 record to show for it. He is a beast on the ground and has won the Abu Dhabi Combat Club Submission Wrestling World Championship twice in his storied grappling career.
More importantly, though, Monson looks like a dude who could mess you up, and with the shaved head, tattoos and history with the law, it's safe to say nobody is picking fights with Mr. Monson.
They don't call him "The Dean of Mean" for nothing.
Keith Jardine is a bad-looking man, and his awkward fighting style makes him all the more intimidating. Unfortunately, Jardine's career was plagued by a glass jaw and his run in the UFC came to a screeching halt after suffering four straight losses (two by KO/TKO).
That said, he's still scary as hell to look at, and for that he gets a spot on my list.
Is there any doubt that Tank Abbott is a man who will gladly throw down? Abbott looks like the kind of guy who gets in fights at biker bars for fun, and you never want to mess with someone with that kind of reckless abandon.
Plus, his goatee is pretty badass.
Even though he stands a mere 5'7" and weighs in at a scant 145 pounds, Jose Aldo is one scary dude. Between the scar on his face and his stoic, almost-too-calm demeanor, Aldo can intimidate any man.
Oh, and he also has knockout power in all eight limbs and a black-belt-level Brazilian Jiu-Jitsu game. Yeah, you probably should just avoid this guy.
Thiago Alves fights at 170, but he weighs closer to 200 pounds on fight night. He is a massive welterweight and is absolutely shredded. "The Pitbull" has brutal KO power in his fists and his legs, but you don't even have to know that; your eyes can tell you he's a dude you shouldn't mess with.
Crazy hair? Check. Crazy muscle tone? Check. Downright crazy? Check.
Between his musclebound appearance and ferocious attitude, Kevin Randleman was a master of intimidation during his run in the UFC.
Take it all in: the glare, the chain, the eyes that just want to destroy you. Yeah, I don't want to fight him either.
The legendary Don Frye is a terrifying man. Between the porn-star mustache and the ridiculously powerful upper body, Frye is the last man you want to meet in a dark alley. Render me intimidated, sir.
Rousimar Palhares is built like a tree stump on steroids, and that scares the hell out of me. He's the kind of guy who can snap off your leg or just throw you out of the Octagon, and for that, he gets the No. 2 position on my list.
That's because of...
At 6'5" and 263 pounds of chiseled physique, Alistar Overeem is one of the few men who has dwarfed Brock Lesnar inside the Octagon.
His build is so ridiculous that he is constantly embroiled in steroid controversy despite regular drug testing that proves he is clean. It's hard to blame them, though—the man doesn't look human, and he is the epitome of an intimidating physical specimen.
I'll just leave this here.
