You grew up on the Island as a member of the Dharma Initiative (1977). You were directly responsible for the death of all of the members of it when you sided with the Others after Sayid shot you, causing the Oceanic 815 Survivors to bring you to Richard Alpert to be healed (which unfortunately destroyed your innocence).
After saving Alex Rousseau from her mother (and thus becoming her adopted father), you played a key role in the destruction of the Dharma Initiative. 58 days after the Oceanic Crash, you were captured by Danielle Rousseau and handed over to the survivors. At first you lied about your identity, claiming to Henry Gale. You used this as an opportunity to play mind games with the Survivors, turning Locke against Jack, warping Sayid to the point of violence and ultimately getting Michael to release him from Captivity.
It was then revealed that you were the leader of the Others, and as such, you became a primary antagonist (and thus comes your role as the GODFATHER
). You captured Jack so that he could perform surgery on you, saving your life.
Upon hearing of the Freighter's existence, you manipulated it so that Michael would be on board. You had him sabotage both the communications equipment and the engines so that you could prevent the crew from reaching the shore. Unfortunately, this didn't work, and it was revealed that the crew was looking for you, not just The Island.
After the Smoke Monster killed the hostile members of the Freighter crew, you knocked The Island out of time.
You were transported off island, where you spent your time trying to reunite the Oceanic Six. You manipulated Jack so that he did so for you, and returned to the Island. Upon finding Jacob, you kill him, causing the Man In Black to become the dominant force on the Island. After Jack kills him, you and Hurley together don the role of the "New Jacob", and protect the Island.
