Jacob Black
Jacob Black is Bella's best friend. He is a Quileute Native American and a werewolf, later revealed to be a shape-shifter as he doesn't transform on the full moon. In Twilight, Jacob plays a minor role, being a forgotten childhood friend of Bella's. In an attempt to learn more about Cullens, Bella flirts with Jacob, and he tells her tribe legends about them being "the cold ones", or vampires. After Edward leaves Bella in New Moon, Bella spends much of her time with Jacob, trying to heal her broken heart and move on. Though at first only a friend, Jacob later falls in love with Bella. Although he spends most of his time in Eclipse trying to win Bella, in Breaking Dawn he imprints —an involuntary process in which a werewolf finds their soul mate— on Bella and Edward's daughter, Renesmee.
Taylor Lautner played Jacob Black in the Twilight film.
Sam Uley
Sam Uley is the leader of the La Push pack. His father, Joshua Uley, abandoned him and his mother when he was very young. Before becoming a werewolf, he was romantically involved with Leah Clearwater, his high school sweetheart. His relationship with her started to fall apart after his transformation, because he was forbidden to tell Leah what he had become. Their relationship ended when Sam imprinted on Leah's second cousin, Emily, and went back on every promise he had ever made to Leah. According to Jacob, Sam feels guilty for betraying her and responsible for the bitter person Leah has become. When he phases, he is pure black and the largest wolf, until Breaking Dawn when it is noted that Jacob has grown taller than him. He is the pack Alpha, but not by blood; that role is Jacob's, but he allowed Sam to lead the pack until Breaking Dawn.
Solomon Trimble was credited as "Jacob's friend" in the Twilight film, but was widely recognized as playing the part of Sam.[11][12][13][14] In the New Moon film, Sam will be portrayed by Chaske Spencer.[citation needed]
The Quileute's
Werewolves/Shape-shifters
Werewolves in the Twilight universe do not age, as long as they regularly phase into wolves. They heal quickly, have enhanced physical speed and strength, and can communicate telepathically with each other while in their wolf forms. At the end of Breaking Dawn, it is revealed that the Quileute tribe "werewolves" are not true werewolves because they don't transform according to the lunar cycle. Instead, they are shape-shifters who take the form of wolves, while the "Children of the Moon" were considered true werewolves.
