whatever people accepts "Badass Normals that eats people are sharing the world with superpowered beings" as a thing, they're tends to be nothing but Fallout characters
in this Scenario, we drop the Lone Wanderer from Fallout 3(particularly when he's totally normal human cannibal here) into either DC or Marvel Universes(Post-crisis-pre-new52 for DCU and Earth-616 for Marvel universe)
how far he goes? what's the reaction of DC or Marvel characters here? and more consequences?
