Either of those are great, but I'd love to start with a per person thing (I am... very fond of this sort of AU, no matter who ends up as what ahah). And if Zack's the pet, whether Cloud picks up a stray with more wolf content in him than he'd expect, or it's a sort of police dog with partner thing within ShinRa, and ShinRa being slightly less questionable here but still messing with their 'special' forces and Cloud is not expecting a wolf? Or got some other thought?
