One of the sets of characters I want to nominate for Phineas and Ferb is a group of seven characters. I haven't been able to trim things down to a point where I don't go over the character cap, but they have a group name-- Firestorm Girls.

That group name is unique to the 2nd Dimension setting, but the members aren't unique to the setting and so have to be tagged 2nd Dimension or some variant if I list them all. I got down to 204 characters, but that's still more than twice the maximum.

I've put them in as Firestorm Girls, but I'm willing to edit if there's a better way to structure the group.
