Pacman and Mexecutioner are pretty good. I think Manila Ice would be pretty cool as well, although it might be double dipping since he named a punch after that. Here's some other possibilities that didn't quite make the cut: Manny "The Manhattan Project" Pacquiao Manny "Nothing Personal" Pacquiao Manny "The Mule Renter" Pacquiao Manny "The Phantom with a Fat Man in His Hands" Pacquiao
hmm says... you do realize that this is a forum and you assume some of these folks like boxers instead of boxing........ if you don't like the topic then why bother to get in and read, post, and then criticize... oh wait it's called a forum..............and it's called shooting the shiet :-(
pacman is just about right...he eats his opponent whole.... he was nicknamed "the destroyer" in his US debut btw....
