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.
