Lets see. Im gonna list a few and will state the reason: Julian Jackson -the power Wilfredo Gomez- the power Salvador Sanchez - the non finishing stamina Julio Cesar Chavez- the undefeated record Time for you to add some to the list
F. Mayweather - Defense Gene Tunney - Footwork O. Usyk - Ring I.Q. B. Hopkins - Longevity Joe Calzaghe - Workrate Roy Jones Jr - Speed James Toney - Counterpunching
Roberto Duran = The Devil himself. Dwight Qawi was intimidating at lightheavyweight. Gerald McCellan- Knocking out a man was better than sex. He said that. He really did.
Mike Tyson was seen as invincible at one point, his aura was like no other. Not hard to read Spink's mind in his ring walk. Sonny Liston and George Foreman too. They all came to really fight.
Joe Louis was making grown men crumble before fights, even tho he wasn't even trying to intimidate them at all.
Carlos Monzon, the heartless machine who just walked you down inevitably, made all the more terrifying by his out of the ring persona.
Larry Merchant called Joe Frazier a truth machine. Always liked that. Prime Papino Cuevas Jack Dempsey Carlos Zarate James Scott was the boogeyman of the division for a while The toughness of Matt Franklin
Jack Johnson beat up his opponents and in the process provoked them because back then they didn't like him because of racism, he was quite scary at that time...
Iran Barkley looked like a caveman. Scary to me. I like a story Ray Leonard related about Thomas Hearns for their first fight. On the press tour, Hearns would wear baggy t-shirts and kind of slump his shoulders and stoop a bit. He did not come off as big nor as tall as he really was. Gave the impression he was just lanky and maybe weak. Then he gets in the ring and they pull off the robe and the Motor City Cobra flexes his cobra-shaped back and he’s ripped to shreds and Leonard said he looked twice as big as he did leading up to the fight. That would intimidating. I be Emanuel Steward was playing some mind games to get Tommy to not show his hand until they were in the ring.
Crawford is pretty damn intimidating. You can see it in his eyes that the only reason he's in a boxing ring is so he doesn't kill somebody. And you know he's there to kill you.
Gerald McClellan looks straight up intimidating and someone you wouldn't want to see inside or outside the ring.
