Pacman, once he has got u in the ring. Outside, he seems like a really nice guy. He is like nite and day. Awesome.
Right now Vitali and Kirkland stand out. At one point i found Cotto had an intimidating look as well.
i would be scared as well when i was in the ring with mike he looks like a pitbull with way too much testosteron. thomas hearns also. and vitali now ofcourse.
First version of Foreman, prolly Liston, Tyson, Tua. As for currrent fighters, Vitali Klitschko and Edwin Valero are extremely intimidating, as said so by their opponents. Kirkland is a bona fide bad-ass as well.
He was most intimidating imo in the Zab Judah fight. That's when I became a big fan of his. I'll never forget that moment when Judah was down and Judah looked over at Cotto in the other corner and when their looks met, Judah looked down and away, like he were scared. After that fight, even in the Mosely win, he seemed to lose some of his "Terminator" aura.
