Hellscreamer

Murdered by a rival, death-metal musician Kgosi “King Screamer” Bamalete was offered a second chance at life by agreeing to become an agent of supernatural retribution, punishing the wicked for their crimes. Now an unforgiving revenant, he battles criminals, cultists, and demons across Sub-Saharan Africa. His harsh methods often put him at odds with other superhumans, though he has teamed up with various supernatural heroes in the past when their goals aligned.
The identity of the entity that resurrected Hellscreamer and gave him superhuman abilities is currently a mystery. It could be a demon, forgotten god, or powerful mystical hero or villain. So far the anti-hero hasn’t been called on by his patron to do anything except punish the guilty; time will tell if this remains the case.
