Killer is Ryan's guard dog-bird. He got him when Ashes ran away and got taken by pigs. Once Ryan retrieved her, he decided to get a dog-bird to gaurd the house from the pigs. When Killer first met Ashes, they fell in love. Despite his vicious appearance, Killer is very tame, friendly, and he's only savage towards pigs (except Hamm, who he loves to play with). He has a red dot on his belly, possibly put as a collar to seperate him from Yellow Birds amd Evan, or it's just a birthmark.
