Benjamin Linus is a fictional character portrayed by Michael Emerson on the ABC television series "Lost". Ben was the leader of a group of island natives called the Others and was initially known as Henry Gale to the survivors of Oceanic Flight 815. He began as the main antagonist during the second and third seasons, but in subsequent seasons, becomes a morally ambiguous ally to the main characters. Other characters frequently describe him as loyal only to himself, though it is also often hinted that he may be driven by some higher purpose.
