A list of characters in the American television series Lost in Space (2018).
The matriarch of the Robinson family, shes a brilliant aerospace engineer and astrophysicist.
- Hot Scientist: She may very well be the most brilliant scientist in the expedition and she is attractive.
- Mama Bear: Do anything that might harm her children and she will come after you with everything shes got. She is even willing to face the Robots.
- Obsessed Are the Listmakers: Drifts near this with her trusty little whiteboard. Her children seem to be the main victims of her task lists.
- Omnidisciplinary Scientist: She describes herself as a rocket scientist, but over the course of the series she becomes the main overall scientist in the expedition. The first episode alone establishes that she's knowledgeable of chemistry and geology.
- O.O.C. Is Serious Business: Only a couple of times when she swears or seriously breaks down under stress.
- Suicidal Pacifism: Her opposition to having a gun is logical on Earth. But opposing her husband's attempt to get the Jupiter's 3D printer to make a gun for self-defense purposes when they're (as far as they know) the only humans on a hostile alien planet that has plenty of aggressive, carnivorous life forms? She might as well soak herself in marinade while she's at it. It also fails to take into account the possibility that they might need to hunt for food to stretch the rations stored on the ship, which requires a weapon of some sort.
The patriarch of the Robinson family, hes a relieved USMC Marine.
- Action Dad: He is extremely active in protecting his children once the expedition is stuck on the planet.
- Adaptational Badass: He was changed from a level-headed astrophysicist to an action-oriented ex-Marine.
- Audience Surrogate: Being one of the only adults who does not have special scientific (like Maureen) or technical (like Don) training, he can allow the others to explain such things without feeling out of place.
- Chronic Hero Syndrome: When civilization nearly collapsed after the Christmas Star meteor strike, John volunteered for active duty in the effort to stabilize the world's governments, because he just couldn't stand by and not do anything. Maureen finding out about this is the reason why they were headed for divorce back before leaving Earth.
- Elites Are More Glamorous: Was a Navy SEAL back on Earth, and it shows.
- Made of Iron: Takes an incredible amount of abuse in Season One alone but keeps going anyway. At one point he gets whacked in the head with a crowbar, completely No Sells it, briefly snarks at the attacker and then knocks him out with a single punch. When Will learns about his dad getting beaten with a crowbar, his first instinct is to ask if John hurt his attacker too badly. It's also a plot point that he can recover from being knocked unconscious faster than anybody else on the planet — a lot faster.
- Papa Wolf: He will not let anything stand in the way of his childrens safety and will put all his military training behind it.
- When You Coming Home, Dad?: He was often away from his family as a Navy SEAL, and he and Maureen were on the verge of divorce over it when the Jupiter mission came along.
The eldest child of the Robinson family, she's a medical doctor at 18 years old.
- Adaptational Intelligence: Judy was an aspiring stage performer in the original series, though she was a doctor in the 1998 film.
- Break the Cutie: The poor girl gets frozen in ice to the point of asphyxiation, then trapped under a huge pile of crates in the next episode. Both of which give her heavy trauma it takes her a while to get over.
- Heroic BSoD: She's left traumatized after being trapped in the ice in the first episode.
- The Medic: Despite her youth, she is a competent doctor. She becomes the main doctor of the survivors of the 24th Colonist Group.
- Puppy-Dog Eyes: Can break out an absolutely amazing pair if the situation demands it. Even Don, who's the most frequent target, can't resist them.
- Race Lift: Judy was played by a Norwegian-born white actor in the original series, but is played by an Afro-Canadian actor in this version. In-universe, she's from Maureen's previous marriage.
- Teen Genius: She is only 18 years old and already a fully trained medical doctor.
The middle child of the Robinson family.
- Audience Surrogate: In a family that consists of an aerospace engineer, a Navy SEAL, a teenage M.D. and a boy genius, Penny is an aspiring author and the one who asks all the questions the viewer might have, i.e. "How far off course are we?"
- Deadpan Snarker: For all of the first season, Penny is the single most sarcastic person in the galaxy.
- Jerk with a Heart of Gold: She's by far the most sarcastic of the Robinsons and is a bit on the lazy side, but she deeply loves her family and does her best to help out when emergencies arise.
- Kid Has a Point: During a flashback to Earth, Maureen comments on Penny purchasing John an expensive watch for Christmas, pointing out that John likely wom't be home for the holiday. Penny's rebuttal is that John is making sacrifices for his family (and the world) by being a deployed Marine and they should be willing to sacrifice for him, i.e. understand and accept the nature of his job, even if they don't like him being gone so often.
- Middle Child Syndrome: She seems to be aware that her siblings receive more attention than herself, however, she hardly holds her siblings responsible for this and has a good relationship with both. She's hardly neglected by her parents either.
The youngest child of the Robinson family.
- Age Lift: His age at the pilot was raised from 9 in the original to 11, for reasons unknown (possibly to closer match the age of his actor, who was 12 while filming the first season).
- Child Prodigy: Will is a genius, saving the day several times over the course of the series with nothing more than his knowledge of science.
- Face Your Fears: Will's core character arc in Season 1 is his belief that he isn't brave enough. He thinks he failed the stress test that was part of the colony screening process, and freezes up when asked to dive down to the Jupiter in "Impact" to retrieve a battery, leading to Judy getting trapped in the ice. The Robot catalyzes his growth as a character: finding a friend and coming to rely on it, being forced to give up that friendship when it proves too dangerous, and finally learning how to stand up for himself.
- Kid with the Leash: The Robot follows his every command. A Robot that could possibly kill everyone on the planet given the chance.
- Nice Job Breaking It, Hero!: Will is a kid, and despite being a Child Prodigy, he is bound to bouts of surprising stupidity, such as destroying the robot, freeing Dr. Smith and taking a loud radio to a stealth mission.
A roughneck mechanic who is also smuggling luxury goods on the side.
- Friend in the Black Market: He is smuggling Scottish whisky to Alpha Centauri.
- Fake American: Don was played by a white American actor in the original series, but by an Argentinian actor this time around.
- Foil: To Smith, best shown by them being the first characters to meet each other and thus getting developed at the same time. They're both amoral, self serving and greedy, but while Don tries to prioritize himself he cannot resist the urge to help others even when it's not to his benefit, whereas Smith will play at helping others but ultimately always chooses herself. Best shown in the way Smith convinces a very reluctant Don to save Angela after the crash, to sell her role as a caring person, but by the time it comes down to her or them Don is the one invested in Angela's safety while Smith responds to the deteriorating situation by playing on Don's soft side and ditching them both.
- Jerk with a Heart of Gold: He puts on the pragmatic smuggler persona most of the time, but when it comes down to it he can be relied on to do the right thing.
- Lovable Rogue: While always on the lookout to make money, cut deals, and smuggle items, Don can be browbeaten pretty easy into doing the right thing. He's also terribly worried about Debbie the Chicken.
- Morality Pet: Despite his initial comments implying that Debbie the Chicken was on the dinner menu, he goes out of his way to protect her, including using his body to shelter her during a diamond rainstorm. His last request to Judy before going on a highly dangerous trip was to make sure that Debbie was cared for if he didn't make it back.
- Noodle Incident: He claims to have a massive scar on his torso, but the incident that allegedly caused it remains nebulous at best thanks to the Robinsons giving their best to shut him up when he tries to tell Will about it.
- Only in It for the Money: The main reason he serves aboard the Resolute seems to be the tidy profit he makes running contraband to Alpha Centauri (he and Tag imply in the pilot that the crew of the Resolute aren't exactly getting rich from their wages, hence the choice to smuggle). When that's no longer an option, he still continues to try and make money off of everyone and everything.
- The Pollyanna: While Don has some downer moments, he seems to be upbeat, snarky and chirpy most of the time.
- Ship Tease: Has quite the chemistry with Judy.
- Wants a Prize for Basic Decency: He demands payment for pretty much everything, much to everyone's exasperation. That he never gets any but ends up helping anyway soon turns into a Running Gag.
June Harris / "Doctor Smith"
A petty criminal who cons her way into the Resolute and assumes the identity of Doctor Smith after being stranded on the planet.
- Adaptational Villainy: She is considerably nastier and more dangerous than the Dr. Smith of the original series. Yet, even that is an understatement. The writers did their homework and had her use brutal, real world tactics to break people.
- At Least I Admit It: When pressed by Maureen late in Season One, Smith makes no attempt to hide her being out only for herself, topped off by claiming that everyone else is just like her; she merely doesn't bother pretending.
- Cain and Abel: She and her sister Jessica do not get along. It's eventually revealed that June drugged Jessica and left her Bound and Gagged in her home after stealing her identity and I.D. chip.
- Chronic Backstabbing Disorder: She double-crosses just about everyone she meets, usually in the guise of helping them. It seems almost compulsive, as she does it even when it puts her at unnecessary risk.
- Critical Psychoanalysis Failure: She's pretending to be a psychologist, and once it furthers her plans she uses it to her advantage. When Angela, the woman she and Don saved in the storm who lost her family to the robot, comes to her in need of guidance, Smith intentionally drives her to an emotional breakdown in order to manipulate her into attacking the robot. There's an intensely creepy moment where she waits outside of Angela's room just to hear the moment where she collapses into sobs.
- Didn't Think This Through: Her Fatal Flaw, negative character traits aside. She rarely seems to plan long-term, or even consider any complications. She schemes to get the Robot destroyed so she can reboot and reassemble it, with no idea how that happened the first time. She wants to fly off in the alien ship even though she has no reason to assume it's spaceworthy. The only reason she manages to get the Robot working again is because of dumb luck.
- Dirty Coward: When backed into a corner or confronted with her duplicity, she will stoop to anything, say anything, do anything, to save her miserable skin.
- Even Evil Has Standards: Brutally averted. Her Mind Screw tactics are positively horrific.
- Evil Cannot Comprehend Good: She doesn't understand that people can be selfless and imagines several reasons as to why someone is doing something rather than for the good of someone else. In the season one finale, she says that Maureen would only save her family because her husband protects her and her children give her life purpose, rather than because she loves them.
- First-Episode Spoiler: "Dr. Smith" is an impostor. She stole the identity of the real Smith during the attack.
- Gender Flip: Played with. There was a male doctor Zachary Smith aboard the Resolute. But June left him for dead during the attack and assumed his identity.
- Hate Sink: Absolutely everything she does serves nobody but herself, consequences for everyone else be damned, and the total lack of remorse and the sheer assholery she displays makes it very hard not to hate her pretty much from the moment she's revealed for what she is.
- Hoist by Her Own Petard: By using the robot to ensure her safety, Maureen manages to create a danger that forces the robot to restrict her to a locked room.
- It's All About Me: Incredibly: from her point of view, everyone else is just insistently in the way of her right to benefit herself. She insists that all people are like this, but that she's just honest about it.
- Karma Houdini: For most of the series until the end. "Smith" gets out of the Robinsons confronting her with her lie of being alone when rescued, confronted by Don whom she left for dead, and even being confronted with evidence that she is not Dr. Smith near the end.
- Kill and Replace:
- While she doesn't directly kill Jessica, she leaves her tied up with everyone thinking she was leaving the planet, so unless she was able to get free on her own she probably ended up dead before the plot kicked off. June then takes Jessica's place on the Resolute.
- She does it again on the Resolute when she takes Dr. Smith's identity and leaves him to die of his wounds.
- Manipulative Bitch: She displays an uncanny ability to read people and zero in on the best angle to manipulate them into doing what she wants. For most of the first season she manipulates everyone on the planet... including the Robot.
- Misanthrope Supreme: She believes all Humans Are Bastards,and the only way to survive is to only rely on yourself.
- Never My Fault: She's shown to have a history of blaming everything that happens to her on other people and refusing to accept any responsibility for her own choices.
- Not So Different: Tries to pull this on Maureen in the Season One finale, with miserable results.
- Pet the Dog: Despite her incredible selfishness, she's occasionally willing to help people so long as it doesn't inconvenience her. This seems to play into her belief that she isn't a bad person, because she can choose to do good.
- The Resenter: "Smith" mainly resents her sister the most, but feels this resentment for the "beautiful people" around her, thinking that they got advantages she didn't and nothing is her fault.
- The Sociopath: She's constantly manipulating everyone around her in attempt to better her own lot in life, no matter how short-sighted, and is thoroughly convinced that no matter who she hurts, she isn't a bad person.
- Tragic Keepsake: The St. Christopher Medal. Subverted in that June let Don think it was in remembrance of a dearly beloved brother. This was a lie to manipulate him into helping her and eventually using it to divert him long enough to steal the flare gun and leave Don and Angela for dead.
- Traitor Shot: Constantly. Most scenes with her end with the person she's talking to leaving the room, and whatever emotion she was pretending to show falling off her face where only the camera can see.
- The Unfavorite: Apparently was this to her father, though we only have her word for it.
The 24th Colonist Group
The elected representative of the 24th Colonist Group.
- The Chew Toy: After being a jerk for most of the show, Victor tries to desert the colonists and leave with his family, taking the last remaining fuel available. Maureen and John stop him after which he moans "I suppose you are in charge now." thinking he's been overthrown for being colony leader. Sort of subverted in that he's back in the saddle in the final episode as the colony leader.
- Lawful Stupid: Victor demands unquestioning obedience from his wife and son and expects the colonists to follow the rules as he interprets them without question. He does not take anyone questioning his authority very well.
- Jerkass: The man is a dick. On has to wonder how he ever got elected to represent the 24th group in the Colony. Especially when everyone voted for the other guy.
- Jerkass Has a Point: While he does raise valid/pragmatic points i.e. it's better to sacrifice one person rather than risk stranding all the survivors, his general attitude and demeanor ensure that no one will listen to him, even when he's right.
- The Neidermeyer: "I voted for the other guy" seems to be the default reaction to Victor being the Colony representative.
Victors teenage son and Pennys love interest.
- Bitch in Sheep's Clothing: When it appears they have no fuel with which to leave, he betrays Pennys trust and reveals to his father the fact that the planet is doomed. Then he goes along with his fathers plan to ditch everyone else on the planet.
- Emo Teen: During the landing, when he thinks he is going to die, the last thing he does is write some truly godawful angsty teen poetry.
- Like Father, Like Son: When push comes to shove, he will ditch everyone else and think only of his family. Just like his dad.
- Love Interest: He is Penny's love interest for most of the first season, until the events of his family's attempted betrayal cause them to split.
- Painful Rhyme: His poetry is horrible and the circumstances under which it was written doesn't prevent Penny from mocking it.
Victors wife and Vijays mother.
- Satellite Character: She doesnt get much of a characterization beyond supporting her husband and son.
Another survivor of the crash, who becomes Victor's number two on the impromptu colony. His original ship is unknown, but he essentially becomes part of the Jupiter 4 crew after the disaster.
- Combat Pragmatist: When an intruder gets aboard the Jupiter 4, he attacks them from behind with a crowbar. Unfortunately, his opponent was John Robinson, a Navy Seal, who knocks Beckert out cold with a quip and a single punch.
- Number Two: De facto, anyway. So much so that he's the only person besides his own family Victor trusts to join him when he attempts to leave the planet.
- Satellite Character: Basically walks around after Victor and does whatever he asks. He has little in the way of personality outside of that.
The 24th Colony Groups preeminent xeno-biologist and a close friend of Maureens.
Hirokis wife, fellow biologist and experience pilot.
- Hiding Behind the Language Barrier: Gives her opinion of Don West's offer of help in a bit of Japanese which is not subtitled for the viewer. Mr. Watanabe translates for her with a simple "No, thank you..." which is obviously not what she said.
- Renaissance Man: On top of being a gifted biologist, she is also one of the best pilots in the 24th Colonist Group.
The Watanabes' only daughter
- Deadpan Snarker: Not on the same level as Penny, but she is quite snarky.
A survivor of the crash whose husband died in the disaster. Don and Dr. Smith find her in the desert, and Don subsequently saves her life when he reaches the other survivors.
- Anti-Villain: "Smith" drives her to try and shoot the Robot, which leads it to nearly retaliate with lethal force. Nobody holds it against her, especially after it comes to light what kind of person Smith really is.
- The Atoner: After she recovers from her breakdown, she becomes invested in helping the Robinsons in regret for what she did.
- Critical Psychoanalysis Failure: She is heavily traumatized by what happened on the Resolute. Sadly, the "doctor" she sees is a charlatan invested in driving her to a total breakdown.
- The Millstone: Initially. She was critically injured by the crash and has to be carried, slowing Smith and Don down when a deadly storm is bearing down on them.
- Not So Different: After everything is said and done, Will lets her know that he has no hard feelings about what Dr. Smith convinced her to do - given that Smith eventually did the same thing to him.
- Shell-Shocked Veteran: She personally witnessed the Robot murdering her husband, and that followed by the crash severely messed her up. She was at first catatonic, but even after that it was a long road to recovery - not helped at all by the presence of a (reformed) Robot and Dr. Smith's machinations. Then Smith gives her a gun...
A recurring survivor who goes with the team to get the remaining fuel left on Don's derelict Jupiter.
- Dying Moment of Awesome: He leaps onto the spokes of the Chariot to reattach the hydraulics to the fuel pod, and would've used his surfer skills to get out of it like a badass if not for the geysers.
- Fatal Family Photo: A variation. Right before he dies of his injuries, he talks about his family, and about the brothers he has waiting for him.
- Heroic Sacrifice: Jumps out of a moving vehicle in the middle of a geyser storm to make sure the fuel gets transported to base. He loses his life for it, and it becomes a Senseless Sacrifice when Judy sacrifices the fuel in an attempt to save him.
- My Greatest Failure: Losing him, and everything else that gets lost because of it, becomes this for Judy.
- Sacrificial Lion: His death marks the beginning of the survivors' long, steadily declining Darkest Hour.
An alien artificial intelligence that attacks the Resolute but later becomes the Robinsons friend.
- Adaptation Species Change: The Robot was Earth-made in the original series, but it is of alien origin this time around.
- A Form You Are Comfortable With: First introduced with a hunchbacked form, with four arms, each with three claws, and four legs, two on each side working in tandem. After saving Will, it scans him, and changes to a much more humanoid form.
- Blue Orange Contrast: Its neutral humanoid form with its blue face and bluish armor contrasts its original alien combat form with red face, reddish armor highlights and orange Energy Weapons.
- Cyber Cyclops: It doesn't seem to have actual eyes, but its big glowy "face" serves the same visual purpose.
- Good Thing You Can Heal: It can reassemble itself even after having been smashed into a dozen pieces under the right circumstances. Never assume it's gone for good just because you witnessed its destruction at some point.
- Grew Beyond Their Programming: After Will saved its life, it followed him wherever he went, and protected him from danger despite being the one responsible for attacking the Resolute and marooning everyone on the alien planet. This later came back into play when a second Robot shows up and attacks the Robinsons, only to be fought off by the first Robot when it nearly kills Will.
- Half the Man He Used to Be: It's introduced as a torso stuck in a tree while its legs try to reconnect to it. The separation nearly killed it, but Will sawed through the branch it was caught in to reunite the two halves, allowing it to recover.
- Multi-Armed and Dangerous: Its combat form, which also appears to be its default one, sports four clawed arms with integrated Energy Weapons.
- My God, What Have I Done?: Seems to be in this mode once it remembers slaughtering the Resolute colonists before the crash. Upon remembering, it rededicates itself to protecting Will (and the other colonists when told to) even to the point of 3D printing a gun for Will to use if the Robot ever goes combaticon again, although Angela proved that the gun is worthless against it.
- Not Evil, Just Misunderstood: Sort of. The robot wasn't attacking the ship just because it was a hostile alien monster, but because humanity stole a powerful engine from its people and, believing the colonists to be enemies, it took down the Resolute to get it back.
- Pokémon Speak: Its initial vocabulary consists of exactly three words that also form its Catchphrase: Danger, Will Robinson. The Season One finale adds three more to the list.
- Red Eyes, Take Warning: Its normally blue face switches to a menacing reddish orange when it goes into combat mode.
- Transforming Mecha: Of a sorts. It takes on two quite different shapes in the first season, and there's nothing to suggest it couldn't assume more if the situation demands it.
- Uncertain Doom: The last scene with the Robot is him flung into the vacuum of space, and that's BEFORE the Jupiter 2 warps to the new system. All evidence points to them having left the Robot light-years away helplessly floating in empty space.
