Seriously, it is... I remember one, a crafty but under rated champion named Leo Cruz who gave Wilfredo Gomez all he could handle and won the WBA title in another war, his rematch with Sergio Palma in 1982. Who else?
George Foreman (unless you count "Big") Ken Norton Lennox Lewis Marvin Hagler officially changed his name to add Marvellous, so it's not a nickname.
I thought “Big” George was a classic? My family aren’t overly boxing people, they followed it (HW scene) in the 80s-90s and they exclusively refer to Foreman as “Big George” it’s actually one of my favourites lol.
Never heard him officially being called any of those. On boxrec he doesn’t even have an alias like other boxers.
