Yeah, it is...
Uh... for actual new teams...
"Outsider" is something I've seen over at mafiascum, but it doesn't really have a base type like most of the other alignments do. The basic idea is that it's vaguely aligned with one side (generally town) but instead of having the normal wincon, they have to gain a certain number of points by the end of the game. They can earn points through, for instance, being on the wagon when a mafia member is lynched or successfully using their abilities against scum. They could also lose points for doing anti town actions (blocking town PRs or helping to lynch townies, for instance).
Note that if they're a roleblocker and they get/ lose points for blocking people, their current amount of points must be hidden to them (otherwise they become a cop too).
Alternatively, they could be scum aligned (and win points for helping with mislynches or blocking PRs) or self aligned with some strange goal.
Point-based? That could work, so long as they weren't scum-aligned. Being scum-aligned causes certainty in their actions, making winning easier. Self or town-oriented (as they aren't aligned) or even scum-oriented could be doable. It'd be kind of like the Diviner, but on a bigger scale with more flexibility.
So far, that would make:
Town
Mafia
Mafia-Ally - See Brother for renaming issues.
SK
Survivor
Cult
Jester
Lyncher
Martyr
Brother - Might require a newer name. Perhaps Ally, since it works like Mafia-Ally. However, if that's the case, I think renaming Mafia-Ally to Ally would work, since they should be allowed to have a Cult-Ally or an SK-Ally or even a Jester-Ally! Mostly, this is all aesthetic.
Outsider
Watcher - This might need a new name, since the very idea was stolen from Paranormal. I would say it falls under Doomspeaker, but he kills them all, so that falls directly under SK.
Maybes:
Kidnapper - This one is still debatable. It could fall under the region of Outsider if taken to an extreme.
Seeker - Again, this could fall under Outsider. It also is a lot simpler than the Lyncher's goal, unless he isn't given a kill. In which case, it's now very difficult. Perhaps their target is Town.
That's 11 Teams with 2 Maybes. I approve.
