[The Italian Stallion]

Either Liston, Foreman, or Tyson

[joho]

tyson he looks scary

[Imira]

Liston, obviously. Not only did he stare right through his opponents, but his mob ties also had them shook.

Tyson. He had that aura of invincibility for a while. Coupled with his attire and unpredictable attitude.

Klitshcko? I'm not sure. Just because he's big doesn't mean he's intimidating. Daunting, yes. Intimidating, not so much.

liston and tyson tops my list....

[Floydmayweather]

Tyson until Douglas goes who fought Tyson would nearly crap their pants when he came foward.

Tyson and the early Foreman. Just the mention of their names and their stares sent shivers down the spine of their opponents. The pre-Ramble-In-The-Jungle Foreman had a very fearsome aura.
