I'm Marvel's Superman...Except I'm a Viltrumite!

I died - and then I woke up, falling from the sky. I somehow stopped myself from falling into an orphanage - except I was still surprisingly hurt, so I still fell unconscious when I hit the grounds of the orphanage. When I awoke, I was inside a room, with a nun cleaning my legs. ...What kind of weird situation had I found myself in now? (A/N - If you don't like hero MC's, don't read. MC is gonna be like an anti-hero-ish Superman.)
