History Characters / LostMainOtherCharacters

* IslandOfMystery: Caves, ancient ruins, castaways, physical anomalies, weird creatures, angry natives, secret research stations, doomsday devices, the Island has it all.

* {{Cult}}: Over the years, Jacob cultivated a group of inhabitants who worship him as a deity.

[[caption-width-right:350:''"The Island is not done with you yet."'']]

A mysterious island supposedly somewhere in the South Pacific. It was settled as far back as the age of antiquity, was colonized by the DHARMA initiative, and is the location of the crash of Flight 815.

* UncannyVillage: The DHARMA Initiative built a small village to house their workers and their families. After the purge, the Others moved in.

* ElaborateUndergroundBase: Many of the DHARMA Initiative's stations were exclusively underground bunkers.

* VillainProtagonist: The BigBad was also a main cast member in the final season. He was also a [[HiddenVillain Hidden]]VillainProtagonist in season 5, as the audience believes he's John Locke until the season finale.

* TravelingLandmass: The Island is constantly moving due to the mystical energy it sits upon.

* AbsenteeActor: While all characters have missed several episodes, Desmond is notable for missing enough in season 4, 5 and 6 that several recurring guest stars were in more episodes than him. ''Especially'' season 5, when he wasn't even in the finale (which usually every living character is in).

* [[BreakHisHeartToSaveHim Break Her Heart To Save Her]]: For his wife, Lara.

* DisappearedDad: To Miles.
* HappilyMarried: Or he was, to Lara Chang.

* DisappearedDad: Implied by Desmond's mention of having to take care of his brothers, but nothing is ever made of it.

* DemotedToExtra: While a recurring character throughout most of the show's run, Penny had a central part in several episodes due to her prominence in Desmond's flashbacks and storylines. In Season 6, however, her part is greatly reduced, with her only appearing in one episode prior to the finale (the Desmond-centric "Happily Ever After") and only showing up in the Flash-Sideways for all of her appearances, never in the present. Her last appearance in the show's present timeline actually occurs in Season 5's "The Variable". And while Sonya Walger was promoted to the main cast list for the series finale, even then, she wasn't given a speaking line.

* BadassBeard: Des sports a scruffy beard from time to time.

* NotSoDifferent: As much as he disdains John Locke and everything he stood for, the Man in Black shares a lot of Locke's self-destructive qualities, which become all the more pronounced when he is trapped in the form of Locke. Like Locke, his obsessive quest for fulfillment leads him to violence and ruin, and he even finds himself repeating Locke's {{Catchphrase}} at one point: "Don't tell me what I can't do!" Not that he would ever acknowledge this, of course.

* MaybeMagicMaybeMundane: When Daniel talks to Desmond during the time flashes in season five, the buzzing that heralds the time jumps begins. Unlike the other characters who aren’t time traveling, Desmond can clearly hear the buzzing and looks around trying to figure out what it is.

->'''Played By:''' Creator/TitusWelliver, Ryan Bradford (child), Carlton Cuse, Simon Elbling, Rob Kyker, Adetokumboh [=McCormack=], Tania Raymonde, Creator/TerryOQuinn, Mirelly Taylor & John Terry

* YourCheatingHeart: He has a second family, and it's strongly implied he frequently has affairs.

* AFateWorseThanDeath: His existence as the Monster. He is physically prevented from leaving the Island, which he'd already been trapped on and trying to escape while still human. The lack of humanity doesn't help. He's spent nearly two thousand years as a cloud of black smoke, capable of imitating life, but unable to truly live or die. Of all the characters who view the Island as Hell, he's the only one

* ItsAllAboutMe: He's ridiculously self-centered, and will gladly destroy everyone and everything that stands in the way of him escaping the Island. If the claims that his escape would cause TheEndOfTheWorldAsWeKnowIt are true, he becomes even more selfish, willing to doom the entire world just to get what he wants.

* StrawNihilist: Despite his obsession with escaping the island to the world "across the sea", The Man in Black really looks down on humanity. Even what he knows of life outside of the Island from looking into people's memories doesn't impress him, as he considers the lives that the Oceanic survivors left behind to be "pitiful."

* HappilyMarried: Eventually, to Desmond.

* SpoiledSweet: Despite being the daughter of an incredibly rich, well-connected and downright evil man, she's kind, smart and perfectly happy to live with Desmond in his downscale flat.

* TheConstant: Desmond and Daniel are the [[TropeNamer Trope Namers]]. Daniel notes that Desmond will be his Constant if anything goes wrong.
