I wonder if Brook knows Special K is street slang for ketamine, he's not exactly a boring fighter that'll make you drowse so it's not an apt nickname.
He does, he's called "Luke" Fury in real life. "Tyson Fury" is a stroke of genius though. "Pretty Boy" is the best current nickname but he's not the first boxer to carry that moniker. SOG is at least fairly original, I think. GGGis also solid. "Homicide Hank" and "Hands of Stone" are the ATG names, they don't make them like that anymore.
''The Fighting Pride of the Philippines'' Pacman ''The Unsolved Riddle of Grand Rapids'' Mayweather ''The Golden Beast of East LA'' Oscar ''The Merciless Curse of Karaganda'' Golovkin ''The Befouled Beehive of Santa Fe'' Maidana ''The Horrible Hunger of Hyde'' Hatton ''The Meditating Mortar of Clearwater'' Thurman ''The Flame-haired Pallbearer of Guadalajara'' Canelo
The best nicknames are the ones where fans use it as their name. So, Money, Pacman, Canelo, Golden Boy maybe...who else has a nickname that fans can use solely by themselves?
