Koi, to a lot of young wolves, has a very unsettling presence. He holds himself high and knows he's great at what he does. He believes his coat is one of the most striking in the pack, along with his Mate, Dream. He believes he and dream go well together because of their display of colors to the other wolves. He loves to go swimming in the nearby lake to keep his coat glossy for all who look at him.
He got the scar on his right back leg because of a quarrel that he started in the middle of a hunt with Lunar. He's upset and hopes the scar doesn't ruin his coat's image.
