Fair enough, But When I think of the most intimidating fighters ever i think of guys who would have their opponents shook before the fight even began. Liston with Patterson, Tyson with Spinks, Hearns with Duran, etc. Guys who were intimidating in demeanor aswell as in style.
Tyson of course, Imagine how scary he would be if he was slightly taller like 6'2 and had a deep voice.
Gerald McClellan. Guy was a bloodthirtsty savage in the ring who took pleasure in hurting and knocking his opponents out.
