Emeka was a warlord leader, much like Eko once was, who blackmailed Yemi's village into giving them profits from vaccine shipments in exchange for protection, from the gang itself. He had blackmailed Yemi into doing the same, however, Eko claimed that he was not afraid of him and would not comply. Emeka shot a blind woman selling Virgin Mary statues outside of the church to prove to Eko that he was serious. Later on The Island, an apparition of Emeka appeared to Eko.
