But no: There are an awful lot of awesome pseudonyms still left, and Jesse Gissen lists his favorites on XXL: Sirius Black: “This bad ass dude from the Harry Potter series is known for practicing black magic, breaking out of prison and being able to turn into a werewolf.

Apparently, there are already a few Kid Viciouses out there. Apollo Creed: Surely some Philly rapper wants to pay homage to this boxer from the Rocky films. Sergeant Slaughter: Whether you’re naming yourself after the wrestler or the GI Joe character, either way you have a built-in beef with rapper Slaughterhouse. It’s perfect!
