Wrongfully sentenced ex-con who underwent an experimental procedure in prison. One of the guards who hated him tried to sabotage the experiment, but it ended up making Cage super strong and resiliant.
He hit his hay-day back in the 70's as Marvel's chief Blaxploitation character, what with his afro, chain belt, yellow shirts with massive collars etc..
Later partnered up with Iron Fist for awhile. Was a member of the Heroes for Hire team. Was hired by Moon Knight as part of the original Marvel Knights team awhile back. Had his own mini-series in 2002 I believe. Recently he's been appearing in Daredevil off and on as a supporting character. As he is one of Bendis' pet characters, he's going to be in New Avengers starting in a bit. He is also currently appearing in the Pulse (prior to that he guested in Alias a lot, again by Bendis) and Secret War (more Bendis, yay!)
His skin is steel hard--lending itself to bullet proof resiliance and is nigh-unbreakable. His super-strength has never been approximatly gauged. It wavers from 4 ton range, to trading blows with the Thing unfazed.
Marvel is discrediting Sabretooth. Bad wiriting is seriously weakening his character. He is a big wuss in Ultimate X-men (can barely fight Wolverine). He gets wailed by Agent Zero (Why God? Why?). It's a sad day for anyone when one of their favorite characters is getting turned into a less than crap support character (who gets his ass kicked to show how cool other crappy characters are) *SIGH* ❌ ❌ Am I going crazy or does anyone else notice this?
