About Michael Dawson

Michael Dawson is a fictional character played by Harold Perrineau on the ABC television series Lost. Michael is one of the survivors of Oceanic Flight 815 who crashes on the show's island. After losing a custody battle with Susan Lloyd, Michael does not see his son Walt for almost ten years. They reunite when she dies, but on their journey home, their plane crashes on a mysterious island in the South Pacific. Here Walt is kidnapped by the Island's previous inhabitants, the Others, and Michael spends his time trying to retrieve him. He is eventually successful, and they leave the Island together, but the guilt over the murders he had to commit to achieve this leads him to an estrangement with his son and a suicide attempt. He returns to the Island on a freighter, but is killed when a bomb on it explodes. Michael reappears as a ghost, and apologizes to Hurley for killing Libby.
