Floyd Mayweather and Bernard Hopkins are serpents they're very deceptive and strike with the right out of nowhere. Both are vicious and won't let you get away with any dirty fighting Floyd has this serpentine like trick where he'll square up and drop his hands to bait the opponent. It's like a cobra raising itself before it strikes
Cotto's face to me looks like a lion, I could put some mane right on him, or a bear. His demeanor is sometimes that of a wounded dog. Tentative, but very dangerous.
