Which superhero should go bad? (Patreon)

I feel like writing a classic "good guy goes bad" story with one of our favorite superheroes and it only made sense to have you guys pick the lucky hero! I haven't quite decided how or why they turn their back on the light side but potential options are possession, alien symbiotes, mind control or hypnosis. We'll see what inspiration leads me towards once you've picked out who's undergoing the change in alignment!
