I have a few packs which I use for stories, I've never gotten around to sorting them all into groups though. They're all based in different parts of the same world, and some of their stories intertwine and overlap. One that I have gotten around to sorting is the
Vamp Pack (Creative, I know...) It's a small group of wolves in which the adults are all pretty much on the same level of control, but Diablo has a slightly higher status within it. His second-in-command is Dreams. They're noctournal and live in a city, where they enjoy hunting the humans who stray too long in the darkness. Diablo found Sentri and descovered his gift for seemingly flicking in and out of existance, making him an almost perfect theif (I believe he's part ghost, I never really figured it out).
I also have a cat clan (I never read Warriors), named Butterfly Clan, in which Nekko is the founder/leader. He came from a human home, and now lives deep in the center of the woods near a long flowing river full of butterflies. He's all white, with black sock-markings on all four paws + his tail. He has overly long whiskers over his eyes, giving his face a veeeeeerrrrrrry faint resemblance to a butterfly. He finds strays to welcome into the pack, which has grown from 1, to 2, to now 27.
Other groups I have scattered throughout my groups are the Mother/Son duo of Jess and Skell (they're in the No Touchie group if you wanna see 'em.), plus Angel, Mikko, and my OC Cane, plus more (as I said, they're scattered).
Might edit later if I think of more...
