Accountant AU! Frank is an accountant, Gerard is an artist. Romcom ensues

It's the high seas at an indeterminate point in history. Gruesome Gerard and Lyn-z face off in a contest of who will be the dominant do-gooder, with Ray the cook, Mikey the first mate, Pete the stowaway, Frank the failed ninja, and assorted others falling over in the background. In short: pirate AU! Thanks to all the usual suspects.

Frank is a late night DJ, Gerard is an avid listener.

Desolation Row AU. The Tipper Laws have consumed the nation; more and more freedoms are being restricted every day. After getting thrown in jail for causing a riot with their illegal punk show, My Chem decides to do the logical thing: cause even more trouble.

Superhero AU written for the Porn Battle Prompt "sidekick"

Great Pumpkin!AU (yes, from Charlie Brown)

Gerard is dressed like a girl and decides to pay Frank a visit.

It's not so much the turning into a girl that's a problem; that's happened before. It's the fact that Frank doesn't turn back.
