A Ficathon Walks Into A Bar

This is the best idea I don't have time to participate in that's come across my desk lately, so here's signal boosting. Basically, it's a crossover ficathon: one submits a character from Fandom A and Fandoms B,C,D,and E, and sabinelagrande will pick a character from B,C,D or E for the character from A to interact with.

... to be honest, I'm really tempted by this. I don't have time, right?
