Tough call for me. Two of my modern favorites going head to head...

I'll go with "Tuaman" although if it were up to me he would be known as "The Terminator" and nothing else.

I always hoped for Tyson Vs. Tua. Something always told me that Tua would blister, bludgeon, pound, pummel, shellac, wallop, and whip Mike Tyson.

And once Tyson's speed was gone it would have surely been a slaughter.
