This isn't really an idea I'm afraid to pitch, more one that I don't see myself GMing for a while, so I figured I'd throw it up here. 

Anyone who's roleplayed with me will know that my niche is the superhero genre, so it goes without saying that this is one such RP. In it, players would control pre-existing Marvel or DC characters -- but that's about as similar as this gets to the Ultimate/Singular/All-Star Universe games that have popped up on the site.

The world is different. It's not the place of freedom your characters remember. Doctor Doom/Lex Luthor/Vandal Savage/Insert Overlord Here governs the US/world with an iron fist, policing everyone, lest they disobey him. Your character remembers that this isn't how the world always was, but no matter who they ask, everyone always tells them to stop being stupid, that it's always been this way. But most of all... your character doesn't have their powers anymore.

Essentially, this RP would follow characters from mainstream/alternate DC and Marvel universes who wake up one day in a world they don't recognise. A big bad rules everything in a dystopian setting, and they don't have their powers or their resources. For example, one player could control Peter Parker, who remembers getting bitten by a spider and swinging around as Spider-Man, but no longer has those powers. Over the course of the RP these characters would get involved in/be thrown into/start a resistance movement, potentially regain their powers, and eventually overthrow the big bad and maybe/maybe not return the multiverse to its previous state.
