Man, I did have an idea but then I lost the dibs lol. My supermutant idea is a mutant who named himself Grognak after breaking off from his gang. He retained enough intelligence to still be able to read and enjoyed reading Grognak comics which got him booted out of his gang. Now he tries to emulate Grognak since he sees Grognak as the strongest human there is and if he goes down the same path he’ll be the strongest there is. That’s the only idea I have at the moment but I’ll try to come up with some others.
