Jacob is a fictional character of the ABC television series Lost played by Mark Pellegrino. He was first mentioned as the true leader of the Others by Ben Linus and was described as a "great man" that was also "brilliant", "powerful" and "unforgiving".[1] He made his first appearance in the final episode of season five. Despite being killed in that episode, he continued to appear as a spirit, as well as in flashbacks in the episodes "Ab Aeterno" and "Across the Sea".
Being an unseen character for much of the series, Jacob is revealed to have been responsible for the plane crash in response to a conflict with his nemesis and brother, The Man in Black. He has been the protector of the island for millennia and has been referred to as "the man in charge." In some of his appearances, Jacob has shown supernatural powers including immortality, healing, omniscience, and changing peoples' destiny to suit his goals. Due to these powers, he has had a considerable influence on the lives of several main characters including Jack Shephard, Kate Austen, John Locke, James "Sawyer" Ford and Hugo "Hurley" Reyes.
