List of Lost characters

The characters from the American drama television series Lost were created by Damon Lindelof and J. J. Abrams. The series follows the lives of plane crash survivors on a mysterious tropical island, after a commercial passenger jet from the fictional Oceanic Airlines crashes somewhere in the South Pacific. Each episode typically features a primary storyline on the island as well as a secondary storyline, a flashback from another point in a character's life.

Out of the 324 people on board Oceanic Flight 815, there are 71 initial survivors (70 humans and one dog) spread across the three sections of the plane crash.

Partial cast of Lost, from left to right: Daniel, Boone, Miles, Michael, Ana Lucia, Charlotte, Frank, Shannon, Desmond, Eko, Kate, Jack, Sawyer, Locke, Ben, Sayid, Libby, Sun, Jin, Claire, Hurley, Juliet, Charlie, Richard, Bernard, Rose and Vincent

Casting and development

Many of the first season roles were a result of the executive producers' liking of various actors. The main character Jack was originally going to die in the pilot, and was hoped to be played by Michael Keaton; however, ABC executives were adamant that Jack live. Before it was decided that Jack would live, Kate was to emerge as the leader of the survivors; she was originally conceived to be more like the character of Rose. Dominic Monaghan auditioned for the role of Sawyer, who at the time was supposed to be a suit-wearing city con man. The producers enjoyed Monaghan's performance and changed the character of Charlie, originally a middle-aged former rock star, to fit him. Jorge Garcia also auditioned for Sawyer, and the part of Hurley was written for him. When Josh Holloway auditioned for Sawyer, the producers liked the edge he brought to the character (he reportedly kicked a chair when he forgot his lines and got angry in the audition) and his southern accent, so they changed Sawyer to fit Holloway's acting. Yunjin Kim auditioned for Kate, but the producers wrote the character of Sun for her and the character of Jin, portrayed by Daniel Dae Kim, to be her husband. Sayid, played by Naveen Andrews, was also not in the original script. Locke and Michael were written with their actors in mind. Emilie de Ravin, who plays Claire, was originally cast in what was supposed to be a recurring role. Kimberley Joseph's character, an unnamed flight attendant, was originally scripted to be killed off in the pilot, but was brought back in Season 2 with the name Cindy and continued to make guest appearances through to the final season, becoming one of the last handful of Flight 815 survivors.

After accidentally killing a greedy doctor while seeking medicine for his wife, he was sold into slavery just minutes before his planned execution. He was imprisoned on the Black Rock as it set sail for the New World. However, a raging storm caused the slave ship to be beached on the island. The Man in Black attempted to trick him into killing Jacob, but Richard was instead recruited by Jacob as an advisor. Jacob also granted Richard eternal youth. Richard has since acted as advisor to the many leaders of the Others, including Ben Linus and Charles Widmore. At the end of the series he is once again able to age and leaves the Island on the Ajira Flight.

Evangeline Lilly After killing her abusive stepfather (later revealed to be her real father), Kate goes on the run and is eventually captured by a federal marshal while in Australia after being taken in by a farmer, Ray Mullen, who planned and carried out his idea of handing her in for the $23,000 reward after seeing her mugshot. Kate works on his farm for nearly three months before being handed over to the US Marshall. On the island, Kate is helpful and participates in leadership alongside Jack. Even though her fugitive status is revealed to the survivors, she still earns their trust. Kate finds herself attracted to Jack and Sawyer, both of whom love her. They each represent a side of her duality and inner conflict. And while circumstances allow for Kate to confront her feelings for Sawyer first and they have an affair, it very quickly unravels due mutual distrust and Kate's deeper and unrelenting feelings for Jack. After escaping the island, she is put on trial for murder, Jack is a character witness at her trial and perjures himself to protect Kate in the hope of jury leniency. Jack's testimony sways Kate's mother from testifying against her and Kate subsequently makes a highly favorable plea bargain that does not require prison time. Kate and Jack eventually move in together and become engaged. They raise Claire's son Aaron as their own, with Kate pretending to be his biological mother as part of the Oceanic 6 cover story. Jack's guilt over raising his nephew while leaving Claire, his sister, and the others behind eventually overwhelms him. He succumbs to bouts of paranoia, jealousy that eventually makes him turn to alcohol and prescription drugs, behaviors that will undo his engagement and send him into depression. At first, Kate resists returning to the island, but eventually decides that she will. She arrives on the island in 1977 and joins the Dharma Initiative, along with Jack and Hurley. Along with them she returns to the present time and searches for Claire. She mortally wounds the Man in Black during his fight with Jack. She pleads with Jack to let the island sink and return home with her. But Jack knows he is mortally wounded and cannot abdicate his responsibility to protect the island.

She defies Ben's orders to infiltrate the survivors' camp, and she has clear romantic feelings for Jack. She is left behind when the Oceanic Six leave the island, and when the recurring time flashes leave Juliet and the others in the mid-1970s, she becomes a mechanic for the Dharma Initiative and starts a relationship with Sawyer.

He cannot leave the island as long as Jacob or one of his successors is still on the island and we are told that if he does leave the island, everyone on earth will die. He first appears as a cloud of black smoke, but can apparently take on the appearance of anyone who is dead. In his Locke avatar, which we are told he cannot now change, he takes offense when Ben calls him a Monster. He claims that he is not evil, and just wants to escape the island.

Name	Actor	Season(s)
Jacob	Mark Pellegrino / Kenton Duty (young)	5, 6
Jacob is The Others' highest authority and has resided on the island for nearly 2,000 years, most recently in a chamber in the foot of the statue of Tawaret, which is the statue's only remaining component. The backstory of Jacob is revealed in the episode "Across the Sea", which, according to the episode's script, took place in A.D. 44; it also revealed the mysterious Man in Black (a.k.a. the "smoke monster") is his fraternal twin and assumed his current supernatural form after an altercation with Jacob. Jacob is the protector of the Island and is able to visit various Flight 815 survivors prior to their arrival, speaking to and conspicuously touching several of the main characters. It seems he granted Richard Alpert's agelessness by touching him on the shoulder (episode "Ab Aeterno"). Ben initially claims to John Locke that he can communicate with Jacob but later reveals he is lying out of embarrassment for his inability to do so, despite being leader of The Others. The figure in the mysterious cabin, who reacted violently to John Locke's flashlight and later is heard by Locke to say "Help me", is at one point presumed to be Jacob; however, it is later implied it may have been his brother, trapped on the island in his "smoke monster" form by Jacob's presence and, as such, has been scheming to ensure Jacob's downfall. The Man in Black is able to assume the appearance of deceased bodies on the island and, through an elaborate series of events involving him arranging the death of, and subsequently impersonating, John Locke, eventually manipulates Ben into killing Jacob; this represents a "loophole" from the apparent "rule" the two brothers could not harm one another.

Eventually, the ghost of Jacob ceded control of the island to his successor, Jack Shephard.

Geronimo Jackson
Geronimo Jackson has been referenced in six episodes of Lost as well as in The Lost Experience. The producers of Lost have asserted that Geronimo Jackson was a genuine, but obscure, 1970s rock band, which released one album entitled Magna Carta. Aside from sources relating to Lost, there is no evidence for the existence of this band. A search of the US Patent and Trademark Office online database lists "Geronimo Jackson" as a word mark owned by Disney Enterprises, valid for all types of housewares, school supplies, stationery, etc. The mark was filed on January 22, 2009. In "The Hunting Party", a Geronimo Jackson album is found by Charlie and Hurley while they are going through all of the gramophone records in The Swan. The band is also referenced in the episodes "The Whole Truth", "Further Instructions", "This Place is Death", "LaFleur", on a poster in John Locke's locker in "Cabin Fever" and at Hurley's birthday party in "There's No Place Like Home". There is a Geronimo Jackson poster in the backgroup when Jack, Kate and Hurley are in the dining hall in He's Our You. A single on iTunes called "Dharma Lady" has surfaced by the band and appears as a song in the film Dear John. "Dharma Lady" was made available to players of the video game series Rock Band through the Rock Band Network, shortly after the airing of the Lost series finale. Geronimo Jackson is actually San Diego–based band, The Donkeys.

Reception

Entertainment Weekly praised the show's fourth season for its "captivating minor characters (tortured Sayid, scheming Juliet, savvy Ben)". In May 2006, McFarlane Toys announced recurring lines of character action figures and released the first series in November 2006, with the second series being released July 2007.
