Hunter's Moon is just what Sebastian's Father called a full Moon. It was not inspired by the preds in any way, shape, or form (that we know of). The clan wouldn't have been called "Huter's moon" anyway. It would be caled something in Predator language; I highly doubt theyu would have named their clan after an occurence on Earth. And for all we know, Scar, Celtic, and Chopper could have all been from different clans. The armor appeared to be for cerimonial reasons (considering they all wore the same type). It wasen't just them; it was all the Preds on the ship plus the Elder. For instance, when going to a funeral/wedding/party/social event/ect., you dress accordingly. Same with the Preds. The fact that Celtic and Chopper ignored the near-dead guy and Scar killed him supports this theory, at least in my oppinion. Different rules for different clans. Also, they didn't really act like they knew each other real well from what I saw. Anyhoo, just a theory.
Oh, and Cory?
"u have way for repeating"
Absolutly no need for that.
