Greatest Fighter of all Time

Who do you guys (and gals) consider to be the greatest fighter of all time? Mo Ali? Rocky Marciano? Bruce Lee? Someone from the UFC? Even a wrestler?! (hmmm...)

Let me know what you think? Or is it too hard to pick just one?

I'll go with Rickson for a start. --------- Robsco! 'I'm sure your style is impressive on other planets, however, your weak link is that this is Earth'

Yo yo Little D,

It has to be HULK HOGAN. He rocked the wrestling world for 20 years, hahahahaha :o) 'Wing Chun 4 Life'

Ok, Ive changed my mind. The greatest fighter of all time is 'Kimbo Slice' 'Wing Chun 4 Life'
