Yuuo, the alpha bitch. Primarily works in the Fullmetal Alchemist fandom. Certifiably insane for this.
Krill, the unwilling beta. Eagerly awaits the new world order, and uses fandom to fulfill her own megalomaniac fantasies.
Ani likes the letter Delta, even if it has nothing to do with the whole pack thing. Plays around in the FMA fandom, and has also been spotted in the Charmed fandom, although when asked she will vehemently deny such accusations.
Joni, the omega if we're gonna keep using the pack metaphor. Dabbles in all kinds of stuff.
The Mounts of the Apocalypse. Because riding the kittens would be difficult, even if we were to find the power of Greyskull.
Death: Needs to get back to her subordinates about what she actually wants to ride. After long discussion, we tentatively say a Paso Fino, being that they are strong, intelligent, and decidedly pale. But Death has to agree first.
Plague: Shall ride a white andalusian stallion in state functions. With a supplemental stable of less obvious horses, of course. Possibly including a few mules.
War: Strong, smart and sturdy, the Russian Don is her chosen battle horse. She'll have a stallion available at all times for battle, and a gelding for when she's mapping out enemy terrain. In addition, she'll keep a small stable of other horses, including a deep chestnut Arabian stallion for state functions.
Famine: The lucky girl, she doesn't need to supplement. Her breed, the Friesian, has it all. Brains, beauty, stamina. Big and black, she cuts an imposing image as she rides through the night to perform her duties.
