is this based off of Steelheart? or is it just a coincidence

fucking loved those books

some ideas i had involve an age-related immortal who can't die from age or sickness, and can modify their outward age at will, or maybe just a general shapeshifter, but i'm flexible

a different idea is an epic who constantly keeps their weakness on them so they seem to be a normal person, either because they dont want to be an epic or because they're being stealthy until the right moment
