Mr. Eko - Eko, also known as Mr. Eko, was one of the tail section survivors of Oceanic Flight 815. He has also been referred to as Eko Tunde, although this may be an alias. He was a notorious war lord and drug smuggler in Nigeria before his brother Yemi's death. To get out of his country he pretended to be a priest, but after Yemi's death, he seemed to take his role more seriously. Eko survived on the Island for 72 days before he was killed by the Monster.
