Wow, it seems there's a lot of interest in a multifandom roleplay. :D
I've brainstormed a bit and came up with an idea. It's an exceptionally weird idea, but I might as well share it with all of you.
In a nutshell; due to some strange distortion in the space/time continuum, various fictional characters are stripped from their universe and land directly in an apocalyptic/post-apocalyptic Earth (still deciding which would be better). Of course, at first they're shocked, confused, angry or a mixture of all three and demand that they return back to their world, but then they realize how much of a dilemma the Earth is in, and how much danger they themselves have gotten into. Eventually, they are forced to confront that they have to learn to adapt to this world, get along with each other and perhaps help out the survivors on this ruined planet in order to survive, while in the meantime they struggle to find a way to return home.
Of course the entire thing will be literate.
It's 2 am here where I live so I apologize for any errors or potholes I've overlooked, and I'm still deciding what kind of apocalypse the world would be in, but generally, how does it sound? Any suggestions to make?
