I meant to unveil this on Halloween, but obviously I'm nowhere near done even with the preliminary sketching, so I'm just going to post it now and ask for feedback.
But first, a bit of an explanation:
I don't think many of you play Team Fortress 2. Most of you haven't even heard of it, probably. For those who'll have, you'll see why I couldn't resist the crossover. For those who haven't... well.
Team Fortress 2 is a video game set in 1968, in which two teams (RED and BLU) fight each other for no apparent reason except that it's their job and they all really like eviscerating people. It's full of the same wacky, cartoony humor that makes Girl Genius so wonderful, which is one of the reasons I think they mixed very well.
I have wanted to do a crossover for some time, but could never decide on who was what class (there are nine different types of fighter you can play in the game, depending on what you're suited to; online, you and other people would presumably each have varied enough tastes to make up a decent team with all nine classes). I finally have my lineup now, however, and so I present to you the extremely crappy, unfinished sketch of the official TEAM GENIUS 2 banner (it's rather large, so click the picture to see it in its full glory).
I could put a detailed explanation of why I chose which class for who (and why there are only seven instead of nine, meaning that I combined a few), but I'll save that for when I do a Meet the Team set of pictures (just like the developers of TF2 did! Gasp!). For now, know that, from left to right, the lineup is (and I'm using the tf2 class names because I haven't been able to think up sutiably Girl Genius-like class names yet): Higgs - Scout, Agatha - Engineer/Pyro, Tarvek - Spy, Klaus - Heavy Weapons Guy, Gil - Sniper (and the only one not really properly sketched, my bad), DuPree - Soldier/Demo(wo)man, Theo - Medic.
Plot-wise? These are the only seven that survived the second Other War. Lucrezia won, and forces them to battle copies of themselves (with slight coloration differences) daily for her own sick amusement. She hasn't told them how to work their weapons-- everything is guesswork, at the beginning, until they start to fall into a team mentality despite initial differences and feuds. I'm looking at YOU, Gil and Tarvek! Very heavy on action and battle sequences, very low on romance and fluff. You know the drill. The typical thing a college-age male would write.
I am VERY excited.
PS: For those that are interested, the official TF2 banner looks something like
this.
