Alright, I think can pick up what you're throwing down.
So as an example, I'd enter as Dr. Gregory House. I have no superpowers of any kind, just a crippling Vicodin addiction, a limp I offset with a cane, and a need to be extremely passive-aggressive and sarcastic when diagnosing patients.
Only now. Now there are greater devils working the spanner, such as Lyu'Zuklik the Prince of Torture. They are significantly less cool than cheating wives trying to convince their husbands they got pregnant asexually.
Unfortunately, my conditional release from prison
and my doctor's license depend on me helping stop the devil horde. You might think prison is better than fighting Beelzebub, but the devils in prison have a tendency to provide suppositories.
