I'unno about whether or not we want to go heroic or villainous on the RP front, and from experience, what we present ourselves as on the team front are what we go by on the RP front as well-so the question of theme is somewhat more important for RPers like me.

We could always revive a theme from the WARs of the old times. The Cullen, Team Trainer, Team Aqua, and Nox all come to mind, though if we really need an original theme I have a few... Most of them are on the villainous side of things, though, or at least antiheroic.
