Black pack

Jacob Black's Pack is formed when Sam Uley and his pack planned to kill Bella and Renesmee in Breaking Dawn. Jacob was ready to kill Renesmee, but could not do so with Bella for he still had. Seth Clearwater soon joined, not thinking it was right to attack their allies with no warning nor provocation. His sister Leah joined soon afterwards to get away from Sam Uley and the memories of their failed relationship, and wound up becoming the pack's Beta. They were instrumental in helping the Olympic Coven protect Bella during her pregnancy. Jacob and Sam's packs resolved their tension when Jacob imprinted on Renesmee.

Afterwards, Jacob's pack claims the protection of Forks and the Cullens as their jobs. While Jacob originally wanted to live as a wolf for a while and Leah decided to join him, the rest of the pack was bound to return to La Push; The plan vas canceled when Jake imprinted on Renesmee.

This pack stood beside the Cullens during the confrontation with the Volturi. They were also joined by Sam's pack which had grown since Jacob left. On this occasion, it was revealed that the pack was actually composed by shapeshifters who could change into wolves, instead of actual werewolves.
