Basically, characters you think it'd be fun (or scary) to see as Big Daddies. Or just because it fits. Or is funny. Or whatever. Little Sister partner optional but a nice touch.
I have three to start:
Lordgenome and Nia (This is the drill that pierces your innards!)
Chachamaru and Evangeline (It really fits, somehow.)
Vash (Trigun) and Flonne (Disgaea) (Because THIS WORLD... IS MADE OF... LOVE AND PEACE! Them doing that to any of the series' villains would be lolzy.)
Feel free to include any fic ideas you get to go with the pairs.
