"The Incident"

Jacob (Iacob in Latin) 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". He made his first appearance in the Season 5 finale "The Incident". He was killed in this episode, but 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, he caused all the events that take place, starting from the plane crash right to the end, in response to a conflict with his nemesis and brother, The Man in Black. Jacob has been the guardian and protector of the island for a very long time and has been referred to as "the man in charge." In some of his appearances, Jacob has exhibited supernatural powers such as having 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.
