Coyote
From Tardis Wiki, the free Doctor Who reference
A coyote was an animal native to at least the western part of the United States. According to Loomis Teague, they posed a significant threat to humans, particularly those who got lost in the hills after nightfall. Despite — or perhaps because of — this reputation, the Doctor was known amongst the Pawnee as "Brother of Coyote". (NSA: Peacemaker)
