Sam Uley

Sam Uley is one of the vampires mentioned in the Twilight series. He is the alpha of the La Push pack. He was the first wolf to phase and has a mature personality, given that he was abandoned by his parents at a young age. He dated Leah Clearwater for a while, but his transformation, as well as his imprinting on her cousin Emily Young ended their relationship. Over the course of the series, he has conflicts with fellow werewolf Jacob Black, although they seem to have reconciled by the end of the series, leading two separate packs.
