Matthew Abaddon was an agent of Charles Widmore. His "mission" is to bring people to the place where they should be.
Matthew Abaddon recruited Naomi Dorrit to lead a group of four people, Daniel Faraday, Charlotte Lewis, Miles Straume, and Frank Lapidus, on a mission to the island. Naomi is wary, convinced that the group is not suited for the job and is concerned what to do if she encounters crash survivors. Abaddon tells her there are no survivors and to just do as she is told. (Confirmed Dead)
Matthew visits Hurley at the Santa Rosa Mental Health Institute and claims to be a lawyer working for Oceanic Airlines, and states that they feel terrible about what has happened to him and offer to upgrade him to a better hospital. As Hurley requests a business card, Abaddon shifts the conversation, and asks Hurley "Are they still alive?" Hurley suddenly becomes very worried, and calls for orderlies to help him. (The Beginning of the End)
