I like fiction podcasts, and the main one I’m working through currently is The Magnus Archives. Each episode is a short first-person paranormal horror story, and they start out pretty standalone, eventually building more background and connections between the stories and adding more “frame story” about the people collecting these tales. I wouldn’t say it’s an SCP clone, but it’s kind of shaped similarly.

I think it’d definitely work that way for your more silly putty shapeshifters like Morph. Someone like Mystique could probably close up cuts and holes, but I’m not sure she could like siphon some mass from other areas to regrow a hand, say.

This just hurts my opinion of T-Pain.
