!!! '''Species:''' Human
!!! '''Played By:''' Shaun Sipos

A human who has travelled through space and time to warn Seg about Brainiac's coming and tell him about [[Franchise/{{Superman}} his future grandson]].
----
* AdaptationalVillainy: To save Superman, [[spoiler: Adam will have to do whatever it takes to ensure his existence. Even if it means allowing Brainiac to steal Kandor, which would eventually lead to Krypton's destruction. Downplayed in that he is genuinely regretful about the necessity, and it becomes clear that he was right to be worried about the future being changed by Krypton surviving]].
* AmbiguouslyBi: Episode 1x05 has him checking out a male Sagitari guard's ass.
** He also says Seg has "dreamy eyes" and "legs for days".
** "Savage Night" hints at a failed romance with Alanna of Rann.
* CompositeCharacter: In backstory and the fact that he is a time traveler, he more closely resembles ComicBook/BoosterGold than his comic counterpart.
* FishOutOfWater: His clothes from Earth don't go unnoticed.
* FlippingTheBird: Gives his middle finger to Kem when the latter chases him away from behind his bar and asks the money for the drink he [Adam] stole. Kem likely doesn't understand the gesture, not being from Earth.
* HeroicSacrifice: [[spoiler:Just when Ona, having recently been turned into a living bomb, is about to kill Seg and his friends, Adam jumps in at the last second and blocks the explosion with his Zeta Beam, all while vanishing at the same time. Subverted in that he survives.]]
* NiceHat: His UsefulNotes/{{Detroit}} Tigers baseball cap. Seg mistakes the "D" for a guild emblem. He reluctantly trades it away on Kem's advice so they can investigate a meteor impact outside the dome, complaining that the Kryptonian he traded it to isn't even a fan.
* NotWearingTights: He dresses in plain streetwear from Earth at first, then starts wearing a Rankless Kryptonian garb to blend in. He wears ''much'' more [[https://vignette.wikia.nocookie.net/marvel_dc/images/a/ad/Adam_Strange_05.jpg/revision/latest?cb=20100206014933 garish outfits]] in the comics. [[spoiler: After being paralyzed by falling rubble in the penultimate Season Two episode, Val-El gives him the classic red suit and jetpack, along with leg braces, so he can keep fighting.]]
* OminousMessageFromTheFuture: Warns Seg about the threat of Brainiac, and about what it's doing to Superman on Earth in the future he comes from. He also gives Seg Superman's cape.
* StatusQuoIsGod: He travelled back in time to preserve history and Superman's existence. [[spoiler:However, this means that Krypton will die anyway for Superman to come to Earth as the infant Kal-El. He doesn't tell Seg about this, which causes a rift between the two.]]
* TeleportersAndTransporters: Superman sent him because he can use a Zeta Beam to warp himself to Krypton's past from Earth, and he came alone because the Zeta Beam doesn't allow passengers.
* TokenHuman: Pretty much the only Earthling of the main cast, as well as the only human in the series.
* UnwittingInstigatorOfDoom: In their brief first meeting, he gives Seg a House of El sunstone from the future - Superman's own. Seg later blames him for his parents' deaths because of that sunstone.

[[caption-width-right:300:''"Krypton, your world is at an end!"'']]
!!! '''Species:''' Coluan cyborg
!!! '''Played By:''' Blake Ritson

Brainiac is a super-intelligent alien android who has existed for thousands of years, possessing the intellectual plunder of countless advanced civilizations. He feeds his insatiable appetite for information by collecting worlds, putting billions of lives in stasis in the process.
----
* ArchEnemy: To Superman, to the point where he goes back in time to destroy his world and prevent his birth. [[spoiler: Except, as it turns out, he never went back in time; his arrival was part of history all along.]]
* BlackEyesOfEvil: His eyes are a solid black with MatrixRainingCode when seen up close.
* BigBad: Of Season One. He was indicated to be this in early [[https://screenrant.com/krypton-tv-show-brainiac-actor/ promotional]] material. [[spoiler: He forms a BigBadEnsemble in Season Two with General Zod and Lobo.]]
* CityInABottle: The first live-action appearance of his city-stealing gimmick. A shrunken city is visible on his ship in one of the first trailers.
* CompositeCharacter: Visually, he's very much based on his post-2008 incarnation (including in the design of his equipment), but apparently he's supposed to be an android like the pre-Crisis incarnation.
* TheCollector: Collects shrunken cities.
* EnemyMine: In the Season Two premiere, he tries to team up with Seg, reasoning that they're both injured and need each other's help. Seg points out that Brainiac would try to kill him as soon as it became convenient, a fact Brainiac doesn't deny, and so decides to just skip the pretense and beats Brainac's body into pulp using a stick. [[spoiler: Unfortunately for Seg, Brainiac survives by putting his mind into Seg's body.]]
* EvilOldFolks: He looks and sounds like an older version of the post-2008 version. [[https://www.youtube.com/watch?v=0WxikiYSnc0 Johns even notes]] that it was important that he appear "ancient".
* EvilSoundsRaspy: His voice is ''very'' raspy and weathered, fitting his incredible age.
* FateWorseThanDeath: He claims that the inhabitants of each city he collects would live forever. That is technically true, however, his idea of eternal life in one of his "bottles" is pretty horrific. Everyone trapped inside is kept in a living stasis, unable to move, never aging, never dying, but trapped in the moment when time froze for them, stuck in place for all eternity...[[AndIMustScream while still completely conscious and fully aware of their surroundings]].
* MakeWrongWhatOnceWentRight: He's come back in time to destroy Krypton and avert Superman's birth. [[spoiler: In fact, Adam Strange is wrong about this. Brainiac was always meant to steal Kandor, which in turn caused the destabilization of Krypton and eventually led to Kal-El being sent to Earth.]]
* OutsideContextProblem: The society of Krypton puts a strict ban on even teaching the possibility that other life exists in the universe. Naturally, they are completely caught off guard when he finally arrives, especially because even for all its advanced technology, Krypton is in the Stone Age compared to the technology Brainiac possesses.
* RoboticPsychopath: An advanced android who destroys planets.
* SatanicArchetype: Fits the role as a harbinger of destruction who is obsessed with having everything under his rule by keeping worlds in bottled containers, essentially creating a "hell" for countless worlds. He also fits in with the Revelations take on Satan: a powerful entity whose arrival brings out the end of a planet's days and is obsessed with ruling his own private collection.
* SuperIntelligence: Standard for Brainiac, and he likes gloating about it.
* TakingYouWithMe: [[spoiler: As he's sucked into the PhantomZone, Brainiac uses his tendrils to drag Seg along.]]
* WhereIWasBornAndRazed: He wiped out his own people after they created him.

!!! '''Species:''' Czarnian
!!! '''Played By:''' Emmett J. Scanlan

-->''"Name's Lobo!"''

A space bounty hunter Seg and Adam Strange bump into.
----
* AmbiguouslyBi: When he's not threatening Seg and Adam, he is commenting on their general attractiveness. He seems to like Adam in particular, referring to him as "a cutie" and "the hot blond". Adam seems genuinely flattered.
* BadassBeard: He sports his iconic goatee.
* BadassBiker: His biker look, which harkens back to his 1990s appearance.
* BigBadEnsemble: He forms this in Season Two with [[spoiler: Brainiac, whom he wants to defeat out of a personal grudge, and General Zod, whom he doesn't care about]] However, he [[DiscOneFinalBoss disappears from the plot]] after [[spoiler: Seg and Adam escape, leaving the expelled Brainiac behind for him to kill]], and when he resurfaces in the finale, [[spoiler: arriving on Krypton after Zod has already been overthrown, he [[EnemyMine forms an alliance with Seg to hunt down Brainiac for good]]]].
* DreadlockWarrior: He sports impressive dreads.
* EeriePaleSkinnedBrunette: True to the comics, his skin is stark gray-white to contrast with his black leather.
* GenreRefugee: ''Krypton'' is a pretty serious sci-fi show overall. Enter Lobo, ''THE'' BloodyHilarious AmusingAlien, in Season 2.
* GutturalGrowler: His voice is usually rather soft and high-pitched, which has never been the case for Lobo before, but it drops into the more familiar growl when he gets especially angry.
* HandCannon: His blaster handgun is ''huge'', yet he's human-sized and uses it with one hand.
* HealingFactor: Getting a basketball-sized hole blown through his torso is a mere inconvenience, as it takes him only a few minutes to regenerate. In the following episode, he shoots his own head off so his body will regenerate from a severed arm on the other side of a forcefield.
* HooksAndCrooks: As in the comics, he uses a chain with a hook.
* RedEyesTakeWarning: He always has them and is most definitely ''not'' someone to be underestimated.
* SkeletonsInTheCoatCloset: He has a skull ornament on his crotch.
* WhereIWasBornAndRazed: He destroyed his own species for laughs. Brainiac then blew up his planet after stealing a city, which really annoyed him because he had the place just to his liking.

[[folder: Doomsday]]
!!''Doomsday (formerly Dax-Baron)''
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/doomsdaykrypton_3.jpg]]
!!! '''Species:''' Mutated Kryptonian
!!! '''Played By:''' Staz Nair (original form)

Doomsday is a monster (or rather, a living weapon of mass destruction) that was created a thousands cycles before the series' present-day as a result of deeply unethical and painful experiments performed by scientists from both the House of El and the House of Zod on a male Kryptonian, Dax-Baron. They initially did so in order to protect Krypton, but then the need faded away and the monster was put into cryostasis due to how extremely dangerous and invulnerable he was. Dru-Zod was convinced Doomsday was the only thing that could stop Brainiac and sought to release him from his prison.
----
* BrainwashedAndCrazy: [[spoiler:Dru-Zod uses a combination of Black Mercy toxin and somatic reconditioning to make him into a loyal tool.]]
* EvilVersusEvil: General Dru-Zod wants to use Doomsday to defeat Brainiac and save the planet, but when Adam Strange reveals that he would kill everyone he finds, Seg convinces Dru-Zod not to use him (or so he thinks).
* HumanPopsicle: Was kept frozen for hundred of years.
* LivingWeapon: Created by the Houses of El and Zod for the purpose of protecting Krypton. Suffice it to say it didn't quite work out that way.
* OmnicidalManiac: It is stated that, if released from stasis, he would kill every living thing on Krypton. After all, he is ''[[NamesToRunAwayFromReallyFast Doomsday]]''.
* NighInvulnerable: His skin soaks up blaster fire with barely a reaction.
* SealedEvilInACan: Let's just say there was a reason Houses El and Zod sealed up their creation instead of using him. He eventually escapes from his containment in the Season 1 finale.
* WasOnceAMan: He was once a Kryptonian soldier named Dax-Baron. He had a unique genetic trait that the Houses of El and Zod exploited to turn him into a living weapon.

!! Sagitari

[[folder: In General]]
!!''The Sagitari''

The military guild and army/law enforcement force maintaining order in the city of Kandor.

* AsskickingEqualsAuthority: The Kandorian Duel allows a Sagitari to contest his/her squad leader's command and earn it if he/she wins said duel.
* BrainwashedAndCrazy: During the failed coup attempt, the Brainiac-possessed Voice of Rao uses his tentacles to corrupt a small group of them, giving them super-human abilities as part of his "Red Shard" personal guard.
* LoweredRecruitingStandards: They greatly increase in number under the dictatorship of General Dru-Zod in Season 2. They do so by recruiting former Rankless like Kem.
* PoliceBrutality: Not quite to Comicbook/JudgeDredd-[=esque=] levels, but they're still seen as brutal oppressors by many Rankless Kryptonians, particularly under the command of individuals like Quex-Ul. Lyta-Zod intends to change things in that department.
* RedShirtArmy: At least one of them dies in almost every episode of Season 1. By Season 2, Dru-Zod's dictatorship turns them into {{mooks}}.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/dev_em.jpg]]
%%[[caption-width-right:300:some caption text]]
!!! '''Species:''' Kryptonian
!!! '''Played By:''' Aaron Pierre

A Sagitari who has always relished his role as a protector of Kandor.

* AdaptationalHeroism: In the comics Dev-Em is a dangerous criminal, although the pre-Crisis version was just a troublemaker who later had a HeelFaceTurn.
* AnArmAndALeg: He's taken over by Brainiac and Lyta is forced to shoot his arm off to protect her mother.
* ArrangedMarriage: He is bound to Lyta-Zod. He's loved her since childhood, but she still loves Seg.
* ArtificialLimbs: He gets a cybernetic limb after losing the flesh and blood one.
* ChildhoodFriendRomance: Seems to be the case... until Lyta kisses Seg again.
* ChildhoodFriends: He was Lyta's friend when they were children.
* DentedIron: His back is covered with scars.
* FreudianExcuse: His parents were killed by Black Zero, who left him with a back full of scars.
* ItsAllMyFault: [[spoiler: After seeing Lyta killed, Dev confessed that he should have tried to save her when he noticed something different about her. But Seg tells him to stop blaming himself, as they all "lost her before she was even killed".]]
* NotQuiteDead: He's shot by Lyta and assumed dead, but manages to survive in the cold until Lyta comes looking for his body as a way to get to Brainiac.
* {{Pornstache}}: He has grown one such by Season 2.
* RaceLift: Like the Zods, the normally white Dev-Em is black.
* UndyingLoyalty: To Jayna-Zod, [[spoiler: even when she's no longer head of the Sagitari.]]

%%[[caption-width-right:300:some caption text]]
!!! '''Species:''' Kryptonian
!!! '''Played By:''' Gordon Alexander

The commander of the 4th Sagitari Squad in which Lyta-Zod and Dev-Em serve.

* NeckSnap: How he meets his demise, courtesy of Lyta-Zod.
* NoHoldsBarredBeatdown: He pulls absolutely no punch in the [[DuelToTheDeath Kandorian duel]] against Lyta-Zod.
* PoliceBrutality: He embodies this in his squad, having no problem brutalizing or killing Rankless people. Which is why Lyta challenges his authority.
* WouldHitAGirl: Justified whe he fights Lyta, as she's a Sagitari like him (there's no gender discrimination in their ranks) and asked for a duel to the death against him.

[[folder: Kol-Da]]
!!''Kol-Da''

%%[[caption-width-right:300:some caption text]]
!!! '''Species:''' Kryptonian
!!! '''Played By:''' Andrea Vasiliou

A Sagitari who has troubles abiding by the new rules Lyta-Zod enforced regarding violence against the Rankless.

* CowboyCop: She flatly ignores Lyta's orders not to indiscriminatingly use violence against the Rankless.
* RabidCop: She has troubles adjusting to Lyta's orders to treat the Rankless with minimal brutality. During the Rankless Initiative, she goes as far as killing an unarmed and shackled prisoner out of fear of being attacked in addition to considering him as a Black Zero sympathizer without any solid proof, which puts her under arrest by Lyta.
* WeHardlyKnewYe: She's killed in her cell shortly after retracting her fake testimony against Lyta-Zod.

!! High Council

[[folder: The Voice of Rao]]
!!''The Voice of Rao''
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/voiceofrao_5.jpg]]
!!! '''Species:''' Kryptonian
!!! '''Played By:''' Blake Ritson

-->''"May Rao's light forever guide your way."''

The deified supreme authority and central religious figure presiding over the High Council of Kandor.
----
* BiblicalMotifs: The gold writing on his robe is Malachi 3 from the Geneva [[Literature/TheBible Bible]], with slight modifications ("Krypton" instead of "Judah" and "Jerusalem") written in Kryptonian script.
* CorruptChurch: He's the central religious figure in Kandor, and its ''de facto'' ruler who maintains a class inequality on purpose. He has no trouble asking for a [[TheScapegoat scapegoat]] for his PR campaign to keep the Rankless quiet as he knows their discontent could turn into outright revolt against his rule.
* CreepyMonotone: He always speaks in the same tone, which makes him kind of creepy. He screams in agony as Brainiac's sentry infects him however.
* TheDreaded: Even Daron is wary of displeasing him.
* TheFaceless: He never takes off his mask, at least when anyone is around. He finally does after being infected by Brainiac.
* GodGuise:
** Seemingly a part of his power rests in that he controls the polarization of Kandor's dome.
** A far more direct and impressive one happens after being infected by Brainiac and seemingly turning into the avatar of the Sun in front of a crowd.
* GoldAndWhiteAreDivine: He wears a white robe with sacred Kryptonian writings, has a quasi-divine status (Rao is the red sun and TopGod for Kryptonians) and his mask representing the faces of Krypton's gods is gilded.
* GoldMakesEverythingShiny: His gilded mask surely shines.
* HighPriest: He presides over public ceremonies to Rao.
* HiddenDepths: Before being assimilated by Brainiac, he’s seen holding and staring at the offering Ona gave him, implying that he was genuinely touched by it.
* IgnoranceIsBliss: Seems to maintain his power by keeping Kryptonians ignorant about other forms of life and civilizations in the universe.
* MalevolentMaskedMan: He wears an elaborate golden mask depicting the faces of Krypton's gods and maintains a form of scientific MedievalStasis by forbidding Kryptonians to research about other worlds and other forms of intelligent life in the universe. It's safe to say Krypton's society, and particularly the Rankless, is ''far'' from being enlightened and happy under his "guidance". Then he is turned into a Brainiac sentry...
* MouthOfSauron: After he is made one of Brainiac's Sentries. Compared to Rhom, who was taken over to gather information, it's his job to subdue the populace for Brainiac's eventual collection.
* MythologyGag: When possessed by Brainiac, he begins to resemble the likewise possessed Milton Fine Brainiac from the comic, as a goateed, mutating man turning green with a growing cranium.
* NoBodyLeftBehind: After being stabbed in the neck with the sunstone key by Nyssa-Vex, his body disintegrates.
* ObstructiveZealot: He's a religious authority figure who holds dominant sway over Krypton's society, religion and government.
* PetTheDog: He seems genuinely impressed with Ona's faith, and is interested in the Rao statuette she gives him. Unfortunately, this leads to his downfall, as the statuette had been infected by Brainiac, and it jumps to him.
* PhotoOpWithTheDog: His on-the-spot invitation and then presentation of Ona, a Rankless child, as a new acolyte before an awestruck crowd of Rankless. The acolytes accompanying him don't appear to be very happy about it.
* PuppeteerParasite: He's infected by Brainiac's Sentry at the end of "Word of Rao".
* VoiceOfTheLegion: After he is transformed into a Sentry.
* WouldHurtAChild: As Brainiac's sentry, he turns Ona into a living bomb so she'll kill Seg and his friends.

[[caption-width-right:300:''"Death to the Voice of Rao!"'']]
!!! '''Species:''' Kryptonians

Black Zero is a clandestine organization that seeks to overthrow the Voice of Rao.
----
* TheScapegoat: They do exist as a serious threat to Krypton's rulers, but fingers are conveniently pointed at them to throw people off-trail, such as Charys-El and Ter-El declaring themselves Black Zero members to protect Seg while they're on trial or Daron-Vex [[BlatantLies poorly justifying]] his intent to search for Val-El's Fortress of Solitude to Jayna-Zod by saying it contains weapons Black Zero could use. Sentry!Rhom's rampage is also blamed on them (due to a lack of information), although Seg informs Lyta-Zod soon enough about it. Then Daron-Vex plans to frame them for an attack he prepares on the Voice of Rao.
* SuicideAttack: A Black Zero member infiltrated the High Council's room with a bomb hidden in his arm. He tried to detonate it on the Voice of Rao, but Seg prevented him from doing so, since his father was in the room and would have been killed as well.
* YourTerroristsAreOurFreedomFighters: To the reigning order in Kandor, they are clearly terrorists. Meanwhile, they consider themselves as LaResistance against said oppressive order.

%%[[caption-width-right:300: ]]
!!! '''Species:''' Kryptonian
!!! '''Played By:''' Creator/HannahWaddingham

The leader of Black Zero.
----
* AdaptationalHeroism: This version of Jax-Ur is a former healer who fights for equality on Krypton (even though she seems to have no problem with using terrorism as a means to get it) and she aids Seg-El in trying to stop Brainiac. [[spoiler:She also appears to want to help Val-El get Seg back from the Phantom Zone]]. The comic book version of Jax-Ur is a MadScientist and the worst mass murderer in the Phantom Zone.
* AntiVillain
* DefectorFromDecadence: She used to be a member of the council alongside Daron-Vex, but fled when he had Val-El killed, fearing she would be next.
* EyeScream: [[spoiler:In Season Two, Jax-Ur's right eye is replaced with a robotic one that shoots lasers.]]
* GenderFlip: The normally male Jax-Ur is played by the very much female Hannah Waddingham here.
* ProperlyParanoid: Her work on the Genesis Chamber made it sustainable for the foreseeable future, but she also knew that in the wrong hands her methods could be used to further the divide between the Rankless and the Guilded by separating the bloodlines. Sure enough, Daron-Vex did exactly that as soon as he got his hands on her work.
* ThatManIsDead: When Daron calls her "Sela-Sonn" she tells him "My name is Jax-Ur now."
* TortureTechnician: She implants Daron-Vex with a device that causes intense pain at the push of a button, even over vast distances.
* UncertainDoom: After being expelled from the Resistance by Val-El, she's last seen wandering alone in Wegthor's tunnels. It's unknown if she perished with the moon's destruction, or escaped with the others or escaped another way.
* WeUsedToBeFriends: She considered Daron-Vex to be one of her closest friends. However, considering that he tried and executed her mentor Val-El and corrupted her work on the Genesis Chamber to achieve a form of immortality for the Ranked, one might assume that friendship is pretty much dead by now.
* YourTerroristsAreOurFreedomFighters: Black Zero ''has'' resorted to terrorist acts--such as an attempted suicide bombing that would kill innocents just to assassinate the Voice of Rao--but their end goal is to establish true equality on Krypton, free of the caste-based society currently in place.

* NiceHat: His UsefulNotes/{{Detroit}} Tigers baseball cap. Seg mistakes the "D" for a guild emblem. He reluctantly trades it away on Kem's advice so they can investigate a meteor impact outside the dome, complaining that the Kryptonian he traded it to isn't even a fan.
* NotWearingTights: He dresses in plain streetwear from Earth at first, then starts wearing a Rankless Kryptonian garb to blend in. He wears ''much'' more [[https://vignette.wikia.nocookie.net/marvel_dc/images/a/ad/Adam_Strange_05.jpg/revision/latest?cb=20100206014933 garish outfits]] in the comics. [[spoiler: After being paralyzed by falling rubble in the penultimate Season Two episode, Val-El gives him the classic red suit and jetpack, along with leg braces, so he can keep fighting.]]
* OminousMessageFromTheFuture: Warns Seg about the threat of Brainiac, and about what it's doing to Superman on Earth in the future he comes from. He also gives Seg Superman's cape.
* StatusQuoIsGod: He travelled back in time to preserve history and Superman's existence. [[spoiler:However, this means that Krypton will die anyway for Superman to come to Earth as the infant Kal-El. He doesn't tell Seg about this, which causes a rift between the two.]]
* TeleportersAndTransporters: Superman sent him because he can use a Zeta Beam to warp himself to Krypton's past from Earth, and he came alone because the Zeta Beam doesn't allow passengers.
* TokenHuman: Pretty much the only Earthling of the main cast, as well as the only human in the series.
* UnwittingInstigatorOfDoom: In their brief first meeting, he gives Seg a House of El sunstone from the future - Superman's own. Seg later blames him for his parents' deaths because of that sunstone.

Brainiac is a super-intelligent alien android who has existed for thousands of years, possessing the intellectual plunder of countless advanced civilizations. He feeds his insatiable appetite for information by collecting worlds, putting billions of lives in stasis in the process.
----
* ArchEnemy: To Superman, to the point where he goes back in time to destroy his world and prevent his birth. [[spoiler: Except, as it turns out, he never went back in time; his arrival was part of history all along.]]
* BlackEyesOfEvil: His eyes are a solid black with MatrixRainingCode when seen up close.
* BigBad: Of Season One. He was indicated to be this in early [[https://screenrant.com/krypton-tv-show-brainiac-actor/ promotional]] material. [[spoiler: He forms a BigBadEnsemble in Season Two with General Zod and Lobo.]]
* CityInABottle: The first live-action appearance of his city-stealing gimmick. A shrunken city is visible on his ship in one of the first trailers.
* CompositeCharacter: Visually, he's very much based on his post-2008 incarnation (including in the design of his equipment), but apparently he's supposed to be an android like the pre-Crisis incarnation.
* TheCollector: Collects shrunken cities.
* EnemyMine: In the Season Two premiere, he tries to team up with Seg, reasoning that they're both injured and need each other's help. Seg points out that Brainiac would try to kill him as soon as it became convenient, a fact Brainiac doesn't deny, and so decides to just skip the pretense and beats Brainac's body into pulp using a stick. [[spoiler: Unfortunately for Seg, Brainiac survives by putting his mind into Seg's body.]]
* EvilOldFolks: He looks and sounds like an older version of the post-2008 version. [[https://www.youtube.com/watch?v=0WxikiYSnc0 Johns even notes]] that it was important that he appear "ancient".
* EvilSoundsRaspy: His voice is ''very'' raspy and weathered, fitting his incredible age.
* FateWorseThanDeath: He claims that the inhabitants of each city he collects would live forever. That is technically true, however, his idea of eternal life in one of his "bottles" is pretty horrific. Everyone trapped inside is kept in a living stasis, unable to move, never aging, never dying, but trapped in the moment when time froze for them, stuck in place for all eternity...[[AndIMustScream while still completely conscious and fully aware of their surroundings]].
* MakeWrongWhatOnceWentRight: He's come back in time to destroy Krypton and avert Superman's birth. [[spoiler: In fact, Adam Strange is wrong about this. Brainiac was always meant to steal Kandor, which in turn caused the destabilization of Krypton and eventually led to Kal-El being sent to Earth.]]
* OutsideContextProblem: The society of Krypton puts a strict ban on even teaching the possibility that other life exists in the universe. Naturally, they are completely caught off guard when he finally arrives, especially because even for all its advanced technology, Krypton is in the Stone Age compared to the technology Brainiac possesses.
* RoboticPsychopath: An advanced android who destroys planets.
* SatanicArchetype: Fits the role as a harbinger of destruction who is obsessed with having everything under his rule by keeping worlds in bottled containers, essentially creating a "hell" for countless worlds. He also fits in with the Revelations take on Satan: a powerful entity whose arrival brings out the end of a planet's days and is obsessed with ruling his own private collection.
* SuperIntelligence: Standard for Brainiac, and he likes gloating about it.
* TakingYouWithMe: [[spoiler: As he's sucked into the PhantomZone, Brainiac uses his tendrils to drag Seg along.]]
* WhereIWasBornAndRazed: He wiped out his own people after they created him.

----
* AmbiguouslyBi: When he's not threatening Seg and Adam, he is commenting on their general attractiveness. He seems to like Adam in particular, referring to him as "a cutie" and "the hot blond". Adam seems genuinely flattered.
* BadassBeard: He sports his iconic goatee.
* BadassBiker: His biker look, which harkens back to his 1990s appearance.
* BigBadEnsemble: He forms this in Season Two with [[spoiler: Brainiac, whom he wants to defeat out of a personal grudge, and General Zod, whom he doesn't care about]] However, he [[DiscOneFinalBoss disappears from the plot]] after [[spoiler: Seg and Adam escape, leaving the expelled Brainiac behind for him to kill]], and when he resurfaces in the finale, [[spoiler: arriving on Krypton after Zod has already been overthrown, he [[EnemyMine forms an alliance with Seg to hunt down Brainiac for good]]]].
* DreadlockWarrior: He sports impressive dreads.
* EeriePaleSkinnedBrunette: True to the comics, his skin is stark gray-white to contrast with his black leather.
* GenreRefugee: ''Krypton'' is a pretty serious sci-fi show overall. Enter Lobo, ''THE'' BloodyHilarious AmusingAlien, in Season 2.
* GutturalGrowler: His voice is usually rather soft and high-pitched, which has never been the case for Lobo before, but it drops into the more familiar growl when he gets especially angry.
* HandCannon: His blaster handgun is ''huge'', yet he's human-sized and uses it with one hand.
* HealingFactor: Getting a basketball-sized hole blown through his torso is a mere inconvenience, as it takes him only a few minutes to regenerate. In the following episode, he shoots his own head off so his body will regenerate from a severed arm on the other side of a forcefield.
* HooksAndCrooks: As in the comics, he uses a chain with a hook.
* RedEyesTakeWarning: He always has them and is most definitely ''not'' someone to be underestimated.
* SkeletonsInTheCoatCloset: He has a skull ornament on his crotch.
* WhereIWasBornAndRazed: He destroyed his own species for laughs. Brainiac then blew up his planet after stealing a city, which really annoyed him because he had the place just to his liking.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/doomsdaykrypton_3.jpg]]
!!! '''Species:''' Mutated Kryptonian
!!! '''Played By:''' Staz Nair (original form)

Doomsday is a monster (or rather, a living weapon of mass destruction) that was created a thousands cycles before the series' present-day as a result of deeply unethical and painful experiments performed by scientists from both the House of El and the House of Zod on a male Kryptonian, Dax-Baron. They initially did so in order to protect Krypton, but then the need faded away and the monster was put into cryostasis due to how extremely dangerous and invulnerable he was. Dru-Zod was convinced Doomsday was the only thing that could stop Brainiac and sought to release him from his prison.
----
* BrainwashedAndCrazy: [[spoiler:Dru-Zod uses a combination of Black Mercy toxin and somatic reconditioning to make him into a loyal tool.]]
* EvilVersusEvil: General Dru-Zod wants to use Doomsday to defeat Brainiac and save the planet, but when Adam Strange reveals that he would kill everyone he finds, Seg convinces Dru-Zod not to use him (or so he thinks).
* HumanPopsicle: Was kept frozen for hundred of years.
* LivingWeapon: Created by the Houses of El and Zod for the purpose of protecting Krypton. Suffice it to say it didn't quite work out that way.
* OmnicidalManiac: It is stated that, if released from stasis, he would kill every living thing on Krypton. After all, he is ''[[NamesToRunAwayFromReallyFast Doomsday]]''.
* NighInvulnerable: His skin soaks up blaster fire with barely a reaction.
* SealedEvilInACan: Let's just say there was a reason Houses El and Zod sealed up their creation instead of using him. He eventually escapes from his containment in the Season 1 finale.
* WasOnceAMan: He was once a Kryptonian soldier named Dax-Baron. He had a unique genetic trait that the Houses of El and Zod exploited to turn him into a living weapon.

!!! '''Played By:''' Creator/CameronCuffe, Nicholas Witham Mueller (as a child)

-->''"The story of my family is one of triumph and sacrifice, how we led a revolution against tyranny. Now it falls on my shoulders to save my world."''

The series' protagonist. He is the grandson of Val-El, the future father of Jor-El, and the future grandfather of [[Franchise/{{Superman}} Kal-El]].

* AdaptationNameChange: His name is spelled "Seyg-El" (or in some versions, he's called Jor-El the First) in the comics.
* AmicableExes: He broke up with Lyta, but they still remain on relatively good terms, enough so that Lyta becomes a FriendOnTheForce for him.
* ArrangedMarriage: Daron-Vex wants him to be the husband of his daughter Nyssa.
* ClearMyName: He fights to redeem the honor of House of El after Val-El's actions caused the family to be ostracized and shamed.
* DoYouTrustMe: Seg constantly asks/declares this to almost everyone over the course of events. They generally do, at least enough to put aside their differences with others.
* HasAType: He explicitly declares that [[ActionGirl Lyta]] will never be more attractive than when she’s punched someone out, right after showing more attraction to Nyssa when he sees that she’s also an ActionGirl.
* TheHeart: Ends up being this for the anti-Brainiac alliance that forms; when the Zods are unable to trust Nyssa, they accept her on Seg’s word. He’s good enough at this that Jayna begins to trust him more than her daughter or grandson.
* HeroicBystander: He inadvertently helps save the Voice of Rao from a suicide-bombing terrorist, as he was actually trying to save his father who was in the vicinity. This act prompts Daron-Vex to express his gratitude, by integrating him in the guilds (he was an outcast up to this point due to House of El being shamed and deemed rankless).
* HeroicLineage: Seg is Superman's grandfather and Jor-El's father, and he is bound to become a hero himself. And his grandfather Val-El himself was a hero for trying to enlighten Kryptonians about civilizations and threats from other worlds.
* {{Homage}}: Seg-El's name is a modified version of Jerry ''Siegel'', one of Superman's creators.
* IKnowYoureInThereSomewhereFight: Pushes Rhom to fight off the will of Brainiac's Sentry while she's about to strangle him. It's enough to release him from the cable-tentacle she was strangling him with and allow him to activate Lyta's EMP grenade.
* RebelliousSpirit: Regularly gets himself in trouble with law enforcement forces, and starts questioning the extreme determinism of Kryptonian society in regards to its DesignerBabies. Then he rebels against the attempt of House Vex to integrate (read: control) him.
* RelatedInTheAdaptation: [[spoiler: Dru-Zod is his son, meaning that similar to the AlternateContinuity series ''ComicBook/SupermanEarthOne'', Zod is Jor-El's half-brother -- and Superman's uncle (though there he was Zod-El).]]
* ShedTheFamilyName: Not out of his own will. He's been forced to drop the use of "El", going by simply "Seg" since his House has been ostracized from Krypton's guilds.
* StarCrossedLovers: He is in a clandestine love affair with Lyta when the series starts (although, it's a poorly-kept secret; their respective families know already), but breaks up with her after her mother Jayna-Zod killed his parents.
* SuperStrength: When he has Brainiac in his body in early Season 2, he can go toe-to-toe with Lobo.
* UndyingLoyalty: He ultimately rejects Daron's offer to join the House of Vex out of loyalty to what was his family.

[[caption-width-right:300:''"We are not alone in the universe!"'']]

!!! '''Played By:''' Creator/IanMcElhinney

Seg's grandfather. He was a staunch believer in space exploration and found out about the existence of other worlds and forms of life in the universe, as well as great threats to Krypton. For simply trying to enlighten Kryptonians about all of this, which meant going against the will of the Voice of Rao, he was condemned to death and his family was ostracized.

* AdaptationNameChange: His name is "Don-El" in the comics.
* BigGood: He serves as Seg's mentor throughout Season One via his VirtualGhost, and after coming back from the PhantomZone, he becomes a key figure in [[spoiler: Jax-Ur's rebellion against Zod's dictatorship in Season Two; he even winds up wresting control from her after she goes too far by executing Lyta]].
* CelebrityParadox: The ''Franchise/StarWars'' movies exist on Earth in the series' universe (they're mentioned by Adam Strange). Creator/IanMcElhinney played Jan Dodonna in ''Film/RogueOne''.
* DisneyDeath: He didn't actually die; he managed to hide in the PhantomZone after jumping.
* GenerationXerox: Prefigures his great-grandson Jor-El, another (and the last) scientist the Kryptonian High Council will ignore, in addition to leaving a VirtualGhost behind before dying. Also, he's the creator of the original Fortress of Solitude. [[spoiler: As if to drive the point home, it turns out late in Season Two that his own father was named Jor-El and was a brilliant scientist devoted to his family; the Jor-El we know is named after him.]]
* IgnoredExpert: His claims about discovering other worlds and threats to Krypton were not only ignored, but also condemned as heresy. It caused the House of El to be ostracized, shamed, and even deprived of its right to have a name.
* LaResistance: He becomes part of one in Season Two against [[spoiler: General Zod's dictatorship over Krypton and plans to conquer the galaxy]].
* OlderAndWiser: The elder of House El, and the boldest Kryptonian scientist in ages.
* TheSmartGuy: Being a VirtualGhost doesn't prevent him from being helpful to Seg and Adam Strange through his immense technological knowledge and knowledge of Brainiac. It also doesn't prevent him from using the technology inside the Fortress of Solitude, thanks to its interface being virtual as well -- Seg and Adam would be pretty clueless with it otherwise.
* VirtualGhost: His Fortress of Solitude holds an AI hologram patterned after himself in a manner that's very similar to Jor-El in ''Film/ManOfSteel''.
* WalkThePlank: He was condemned to the Kryptonian equivalent, that is walking on a bridge which ends at a chasm outside the energy shield of Kandor (which protects the city from the cold environment of that part of the planet), then being dropped in said chasm through the [[TrapDoor retractable end]] of said bridge. However, he wound up surviving by opening a portal to the PhantomZone, from which Zod frees him in the Season One finale.

* SuicideByCop: She very likely knew what was going to happen when she took the blaster gun Ter drew seconds earlier in the court room.

* MythologyGag: His cape is almost exactly the same as the one worn by Creator/ChristopherReeve's Superman, down to sporting the yellow S-shield.
* RetGone: His cape is slowly vanishing from existence, which means it's also happening to him. [[spoiler: In the Season One finale, the defeat of Brainiac by way of PhantomZone projector, and Seg-El getting sucked in with him, causes Superman's symbol to be replaced by Zod's on the cape.]]

!!! '''Played By:''' Elliot Cowan

The chief magistrate of Kandor, charged with defending Krypton's oligarchy.

* BadLiar:
** Claims he wants to find Val-El's Fortress of Solitude so the terrorists of Black Zero won't find potential weapons to Jayna-Zod. She doesn't buy it.
** Brainiac seems insulted by how bad his alibi for the coup attempt is.
* DirtyCoward: If he wasn't always already one all along, he definitively sinks himself into that abyss when he tries to kill his own daughter to save his own neck.
* FreudianExcuse: Along with his RagsToRiches background, according to his own telling, he came from a family of Cythonnites (worshippers of Cythonna, instead of Rao) and were victims in the religious purges decades past. Hence, supposedly why he's an ambitious, scheming (and secretly atheistic) social and political climber one moment, and a simpering sycophant the next.
* HowTheMightyHaveFallen: [[spoiler: In the Season Two premiere, he's been reduced to scraping out a living as a laborer on Wegthor, far from the powerful position he once held.]]
* ItsAllAboutMe: He admits to Jayna-Zod that he's primarily self-motivated, but insists that he still offers a better future for Krypton than the Voice of Rao, who has no interest in anything other than maintaining the status quo.
* TheJudge: Pronounces the sentences for whoever commits major crimes against the Kryptonian society (according to the High Council anyway).
* KilledMidSentence: [[spoiler: He gets shot in the head by Lyta before he can reveal the truth to Nyssa. Lyta believes he was going to lie to her again.]]
* NumberTwo: The main pawn of the Voice of Rao.
* OffingTheOffspring: Once he allies with Brainiac, he reluctantly tries to execute his own daughter personally rather than subject her to a public execution. She expected he might try this and tricked him into shooting a hologram.
* PetTheDog: He decides to reintegrate Seg into Krypton's guilds, albeit by making him a Vex and a TrophyHusband for his daughter, and he only does so to prove that the House of El can be "tamed." Seg ultimately rejects this offer, much to Daron's dismay.
* TheQuisling: Once Brainiac foils his coup, Daron is quick to pledge himself to Brainiac, rationalizing that life as his underling is better than death against an implacable foe.
* RagsToRiches: According to Jayna-Zod, he married into the House of Vex and quickly set about turning it into one of the most important houses in Kandor.
* SmugSnake: A self-admitted "selfish bastard" with numerous schemes and plots, but one who clearly lacks the patience and the discipline to adapt to your everyday SpannerInTheWorks and suffering from some degree of EvilCannotComprehendGood. It especially contrasts with his more skilled and moral daughter.
* TheStarscream: He's plotting a coup to take power from the Voice of Rao.
* UncertainDoom: He tries to flee Kandor in a skimmer after losing everything, but Jax-Ur triggers a torture device in his neck that causes him to crash. It's not clear if he survived the crash or found shelter if he did. [[spoiler: He is shown to have survived in Season Two, scraping by in his old hometown, [[BackForTheDead until Lyta shoots his head off]].]]
* VillainRespect: He condemned Val-El to death, helping the Voice of Rao to maintain his power over Kryptonian society, but still admired him as he was undoubtedly Krypton's greatest scientist.
* VisionaryVillain: He wants to take over so he can broker alliances with the other cities on Krypton, ultimately allowing Kryptonian society to advance beyond the stasis it's currently in.

* HeelFaceTurn: She winds up turning completely against her father's plans in favor of helping Seg, and come {{the reveal}} that [[spoiler: she's actually a clone of the original Nyssa-Vex, she becomes so disillusioned with her life that she rejects the Vex name for her son, wanting him to be an El instead]].

** While manipulative and ambitious, she seems to show some integrity and pragmatism. Definitely moreso than her father.
** She's also a hidden ActionGirl, thanks to a former lover who was a combat instructor.

* MsFanservice: She wears alluring dresses and makeup, and has a nude scene.
* PerfectlyArrangedMarriage: How she sees the union between her and Seg that her father planned. She claims that her father thinks it was he who chose Seg to marry her, implying she influenced him for that choice. She also compliments Seg by telling him how he's "[[{{Hunk}} not completely repellent]]".
* ProperlyParanoid: She knows her father well enough to know he might sell her out to save his own skin. When the coup fails, she has a hologram set up in her room just in case he might try to blame the coup on her.
* ReasonableAuthorityFigure: If her actions regarding Seg and Lyta can be taken at face value.
* TomatoInTheMirror: Jax-Ur reveals that [[spoiler:she's not the original Nyssa-Vex. The original was mortally wounded in a skimmer crash as a child, and her mind was uploaded into a clone body. This destroys whatever lingering loyalty she had to her father]].

* HonorBeforeReason: Honor is SeriousBusiness for the House of Zod. She's devastated when Lyta is framed for the killing of a Rankless during the Rankless initiative instead of Kol-Da. Though by Season Two, she doesn't care about honor anymore.
* FreudianExcuse: Her...issues with expressing her love for her daughter and her general HonorBeforeReason obsession come from her father not just making her and her brother fight each other ruthlessly to be worthy of the name Zod, but also deliberately arranging their final trial so that one of them would be required to abandon the other to a cruel, cold death.
* MercyKill: How she sees the killing of Ter-El and Charys-El by her hand.
* [[AFatherToHisMen A Mother To Her Troops]]: It deeply pains her at having to abuse the trust and loyalty of her Sagitari, and is in tears when forced to kill one of them herself.
* MumLooksLikeASister: She doesn't look old enough to be Lyta's mother.
* MyGreatestFailure: A flashback reveals that years ago she left her brother to certain death in the Outlands for her own survival, which gained her their father's praise as being worthy of a Zod, but has haunted her ever since. Later subverted when she's found by her still-alive brother, who bears her no ill feeling and helps her get safely away from Lyta and Dru-Zod, after Lyta shoots her. [[spoiler: Subverted again when it's revealed that she was imagining her brother still alive, rescuing and forgiving her.]]
* ReasonableAuthorityFigure: While Daron-Vex and the Council come off as (somewhat fearful) stooges to the Voice of Rao and she comes off as a hardass, she's also the most relatively sympathetic of Krypton's leaders so far.
* TheSmartGirl: She's more than just a "blunt instrument", as Daron is quick to call her following the death of Seg's parents by her hand. For instance, she isn't fooled by Daron's claims to find Val-El's Fortress to prevent the Black Zero terrorists from getting their hands on potential weapons. She also figures out Charys and Ter sacrificed themselves to avoid the same punishment as Val and to protect both their son and the fortress's location.

A Sagitari cadet and the daughter of Primus Jayna-Zod. After challenging her squad commander Quex-Ul in a duel and killing him, she succeeds him as commander of the 4th Squad.

* ActuallyADoombot: [[spoiler: She's killed by Jax-Ur at the end of 2x05, only for Dru-Zod to reveal three episodes later that the real Lyta is being kept in a coma by the Black Mercy. The one Jax-Ur killed was a clone he made who was programmed to not object to his plans.]]
* AmicableExes: Seg broke up with her, but they still remain on relatively good terms. Enough so that she becomes a FriendOnTheForce for Seg.
* BrainwashedAndCrazy: [[spoiler: It's revealed in "Danger Close" that she's been reconditioned by her own son, though Zod asserts in the following episode that he only put her through it to alleviate her guilt over shooting her mother. Then it turns out in "Mercy" that was actually a clone of Lyta, and the real one is being held in a Black Mercy coma.]]
* CanonForeigner: She's a new character who didn't appear in the comics.
* DefiantToTheEnd: [[spoiler: Before she was killed by Jax-Ur, she told Zod not to give in to Jax-Ur's demands to save her.]]
* FaceHeelTurn: [[spoiler: Becomes a willing supporter of her future son's regime, going as far as shooting her mother and brutally torturing dissidents. Played with when it turns out she was brainwashed, then subverted when it turns out that wasn't even Lyta, just a clone Zod had made; the real Lyta, upon being freed from the Black Mercy, vows to help stop him.]]
* FollowInMyFootsteps: She became a Sagitari like her mother.
* FriendOnTheForce: She's this to Seg, helping him while knowing full well her hierarchy would disapprove.
* InternalReformist: Tells Seg she wants to change things, and given her attempts to put a stop to police brutality, she seems as good as her word.
* IronicEcho: She reprises her mother's "The ability to divorce oneself from emotion" words... and puts her own spin on it when briefing her squad for the Rankless Initiative.
-->'''Lyta:''' The ability to divorce oneself from emotion is what separates a successful mission from failure.
* KlingonPromotion: By killing Quex-Ul without mercy in a [[DuelToTheDeath Kandorian duel]], she becomes commander of his Sagitari squad.
* LoveInterest: Of Seg, until he breaks up with her because her mother killed his parents.
* ReasonableAuthorityFigure: What she becomes in her squad after taking Quex-Ul's place. She does her best to ban needless violence against the Rankless.
* TheScapegoat: Following the orders of the Voice of Rao, who wants a higher up [[TheScapegoat scapegoat]], Daron-Vex frames her for the killing of a Rankless during the Rankless initiative (while Kol-Da actually did it).
* StarCrossedLovers: Her love affair with Seg is forbidden since Seg's family has been shamed and its name deemed to disappear. It is no longer an issue once Seg breaks up with her.
* TookALevelInBadass: She goes from bumbling trainee begging for mercy when subdued to killing her own commander (who's much stronger than she) in a duel to the death, putting her mother's "no mercy" teachings in practice surprisingly fast and efficiently.

-->''"Our existence is at stake, and if you fail to understand that then you are just another idealistic El without the stones to affect real change."''

A member of the Black Zero terrorist organisation, said to be a fast riser in their ranks. He takes Seg prisoner and tortures him for information on Brainiac (and to see if Seg was a Sentry). It is revealed that he is Dru-Zod, Lyta-Zod's son from the future, better known as "General Zod" in most ''Superman'' media.

* ActuallyPrettyFunny: His reaction to being accused of being aligned with Black Zero is to laugh.
-->'''Dru-Zod:''' If Black Zero knew about Brainiac, do you think they'd be wasting time battling that six-faced liar and his unraveling theocracy?
* AntagonisticOffspring: To Seg and Jayna.
* ArchEnemy: Adam Strange outright labels him Superman's greatest enemy in "Civil Wars." Later, Zod all but confirms Adam's accusation by explaining to Seg that he simply disapproves of his grandson.
* TheBadGuyWins: By the end of the Season One finale, [[spoiler: Krypton is successfully saved from Brainiac, but Seg ends up trapped in the PhantomZone and Dru-Zod takes over the planet as a dictator]].
* BaldOfEvil and BeardOfEvil: Gee, I wonder if he's a good guy or not?
* BigBad: He is this in Season Two [[spoiler: due to having conquered Krypton in the wake of Brainiac's defeat and apparent death. However, it's more of a BigBadEnsemble, as Brainiac is still hanging on inside Seg's mind and Lobo is now on the hunt]].
* CanonCharacterAllAlong: He's introduced as a mysterious Commander in Black Zero pursuing his own agenda; only at the end of Episode 1x05 and beginning of 1x06 is he revealed to be ''the'' General Zod.
* ColdBloodedTorture: Used a particularly nasty parasite that burrowed into Seg's head to see if he was one of Brainiac's Sentries.
* DisappearedDad: He doesn't know who his father is, only that he died fighting Brainiac in the Battle of Kandor. [[spoiler: Then he deduces this was a lie -- his father is none other than Seg-El. Even so, Seg hasn't been part of Zod's life growing up.]]
* EvilSoundsDeep: His voice is a suitably authoritarian and menacing baritone.
* EvilVersusEvil: Not taking into account that he is one of Superman's greatest enemies, Zod had a plan on how to save Krypton from Brainiac. That plan's name is [[spoiler: Doomsday]]. Fortunately, he is convinced by Seg and Adam not to go through with it.
* KidFromTheFuture: It is revealed in "House of Zod" that he is Lyta's son.
* KnightTemplar: He will do ''anything'' to protect Krypton, even if it means unleashing Doomsday to fight Brainiac.
* LukeYouAreMyFather: He reveals to Lyta that he is her future son. [[spoiler: Then he figures out that Seg is his father.]]
* MetaphoricallyTrue: Everything he tells Seg about his grandson is true, but he conveniently leaves out that he was friends with Jor-El until he attempted a coup, Kal-El was a baby when he was shipped out so of course he knew only a fraction of his Kryptonian heritage, and Zod attempted to conquer Earth.
* RaceLift: The usually white Dru-Zod is played by Colin Salmon here.
* RelatedInTheAdaptation: [[spoiler: He's the son of Seg-El and Lyta-Zod, meaning that similar to the AlternateContinuity series ''ComicBook/SupermanEarthOne'', Zod is Jor-El and Zor-El's half-brother--and Superman and (presumably) Supergirl's uncle (though there he was Zod-El)]].
* SecretTestOfCharacter: He has Seg tortured just to see if he was still Kryptonian because Sentries don't respond to torture. It isn't until he stops torturing Seg that Zod reveals his intent.
* TokenEvilTeammate: In the team that forms in the struggle against Brainiac. Even with none of their hands being clean as Seg put it, compared to Seg, Lyta, Jayna, Nyssa, and Kem, General Zod is definitely this.
* TyrantTakesTheHelm: In the Season One finale, [[spoiler: with Brainiac gone and Kandor's leadership splintered, he takes control of Krypton as a dictator, conscripting the Rankless into his army]].
* WellDoneSonGuy: [[spoiler:Growing up without a father, Zod always wanted his approval from Seg. But seeing what Seg is like (more like Jor-El and Kal-El), he no longer needs ''anything'' from him anymore.]]
* WellIntentionedExtremist: He would happily work with (or perhaps more accurately he is using) a terrorist organization, torture Seg with parasites, and unleash ''Doomsday'' if it meant he could stop Brainiac's conquest of Krypton. [[spoiler: However, he proves to be a NotSoWellIntentionedExtremist when he conquers Krypton and seeks to expand it into a galactic empire, laying waste to the future and ensuring Superman never exists.]]
* VillainsNeverLie: He's quite upfront about his attempted coup and history with the El family when Jayna confronts him about how he survived Krypton's destruction. Though he frames it as rebelling against weak leadership just as she had in the present, she suspects his true motive is to conquer Krypton in the past after saving it from Brainiac. [[spoiler:She's right on the money.]]

* AsskickingEqualsAuthority: The Kandorian Duel allows a Sagitari to contest his/her squad leader's command and earn it if he/she wins said duel.
* BrainwashedAndCrazy: During the failed coup attempt, the Brainiac-possessed Voice of Rao uses his tentacles to corrupt a small group of them, giving them super-human abilities as part of his "Red Shard" personal guard.
* LoweredRecruitingStandards: They greatly increase in number under the dictatorship of General Dru-Zod in Season 2. They do so by recruiting former Rankless like Kem.
* PoliceBrutality: Not quite to Comicbook/JudgeDredd-[=esque=] levels, but they're still seen as brutal oppressors by many Rankless Kryptonians, particularly under the command of individuals like Quex-Ul. Lyta-Zod intends to change things in that department.

-->''"May Rao's light forever guide your way."''

The deified supreme authority and central religious figure presiding over the High Council of Kandor.
----
* BiblicalMotifs: The gold writing on his robe is Malachi 3 from the Geneva [[Literature/TheBible Bible]], with slight modifications ("Krypton" instead of "Judah" and "Jerusalem") written in Kryptonian script.
* CorruptChurch: He's the central religious figure in Kandor, and its ''de facto'' ruler who maintains a class inequality on purpose. He has no trouble asking for a [[TheScapegoat scapegoat]] for his PR campaign to keep the Rankless quiet as he knows their discontent could turn into outright revolt against his rule.
* CreepyMonotone: He always speaks in the same tone, which makes him kind of creepy. He screams in agony as Brainiac's sentry infects him however.
* TheDreaded: Even Daron is wary of displeasing him.
* TheFaceless: He never takes off his mask, at least when anyone is around. He finally does after being infected by Brainiac.
* GodGuise:
** Seemingly a part of his power rests in that he controls the polarization of Kandor's dome.
** A far more direct and impressive one happens after being infected by Brainiac and seemingly turning into the avatar of the Sun in front of a crowd.
* GoldAndWhiteAreDivine: He wears a white robe with sacred Kryptonian writings, has a quasi-divine status (Rao is the red sun and TopGod for Kryptonians) and his mask representing the faces of Krypton's gods is gilded.
* GoldMakesEverythingShiny: His gilded mask surely shines.
* HighPriest: He presides over public ceremonies to Rao.
* HiddenDepths: Before being assimilated by Brainiac, he’s seen holding and staring at the offering Ona gave him, implying that he was genuinely touched by it.
* IgnoranceIsBliss: Seems to maintain his power by keeping Kryptonians ignorant about other forms of life and civilizations in the universe.
* MalevolentMaskedMan: He wears an elaborate golden mask depicting the faces of Krypton's gods and maintains a form of scientific MedievalStasis by forbidding Kryptonians to research about other worlds and other forms of intelligent life in the universe. It's safe to say Krypton's society, and particularly the Rankless, is ''far'' from being enlightened and happy under his "guidance". Then he is turned into a Brainiac sentry...
* MouthOfSauron: After he is made one of Brainiac's Sentries. Compared to Rhom, who was taken over to gather information, it's his job to subdue the populace for Brainiac's eventual collection.
* MythologyGag: When possessed by Brainiac, he begins to resemble the likewise possessed Milton Fine Brainiac from the comic, as a goateed, mutating man turning green with a growing cranium.
* NoBodyLeftBehind: After being stabbed in the neck with the sunstone key by Nyssa-Vex, his body disintegrates.
* ObstructiveZealot: He's a religious authority figure who holds dominant sway over Krypton's society, religion and government.
* PetTheDog: He seems genuinely impressed with Ona's faith, and is interested in the Rao statuette she gives him. Unfortunately, this leads to his downfall, as the statuette had been infected by Brainiac, and it jumps to him.
* PhotoOpWithTheDog: His on-the-spot invitation and then presentation of Ona, a Rankless child, as a new acolyte before an awestruck crowd of Rankless. The acolytes accompanying him don't appear to be very happy about it.
* PuppeteerParasite: He's infected by Brainiac's Sentry at the end of "Word of Rao".
* VoiceOfTheLegion: After he is transformed into a Sentry.

----
* TheScapegoat: They do exist as a serious threat to Krypton's rulers, but fingers are conveniently pointed at them to throw people off-trail, such as Charys-El and Ter-El declaring themselves Black Zero members to protect Seg while they're on trial or Daron-Vex [[BlatantLies poorly justifying]] his intent to search for Val-El's Fortress of Solitude to Jayna-Zod by saying it contains weapons Black Zero could use. Sentry!Rhom's rampage is also blamed on them (due to a lack of information), although Seg informs Lyta-Zod soon enough about it. Then Daron-Vex plans to frame them for an attack he prepares on the Voice of Rao.
* SuicideAttack: A Black Zero member infiltrated the High Council's room with a bomb hidden in his arm. He tried to detonate it on the Voice of Rao, but Seg prevented him from doing so, since his father was in the room and would have been killed as well.

* EyeScream: [[spoiler:In Season Two, Jax-Ur's right eye is replaced with a robotic one that shoots lasers.]]
* GenderFlip: The normally male Jax-Ur is played by the very much female Hannah Waddingham here.
* ProperlyParanoid: Her work on the Genesis Chamber made it sustainable for the foreseeable future, but she also knew that in the wrong hands her methods could be used to further the divide between the Rankless and the Guilded by separating the bloodlines. Sure enough, Daron-Vex did exactly that as soon as he got his hands on her work.
* ThatManIsDead: When Daron calls her "Sela-Sonn" she tells him "My name is Jax-Ur now."
* TortureTechnician: She implants Daron-Vex with a device that causes intense pain at the push of a button, even over vast distances.
* UncertainDoom: After being expelled from the Resistance by Val-El, she's last seen wandering alone in Wegthor's tunnels. It's unknown if she perished with the moon's destruction, or escaped with the others or escaped another way.
* WeUsedToBeFriends: She considered Daron-Vex to be one of her closest friends. However, considering that he tried and executed her mentor Val-El and corrupted her work on the Genesis Chamber to achieve a form of immortality for the Ranked, one might assume that friendship is pretty much dead by now.
* YourTerroristsAreOurFreedomFighters: Black Zero ''has'' resorted to terrorist acts--such as an attempted suicide bombing that would kill innocents just to assassinate the Voice of Rao--but their end goal is to establish true equality on Krypton, free of the caste-based society currently in place.

* TokenHuman: Pretty much the only Earthling of the main cast, as well as the only human in the series.
* UnwittingInstigatorOfDoom: In their brief first meeting, he gives Seg a House of El sunstone from the future - Superman's own. Seg later blames him for his parents' deaths because of that sunstone.

Brainiac is a super-intelligent alien android who has existed for thousands of years, possessing the intellectual plunder of countless advanced civilizations. He feeds his insatiable appetite for information by collecting worlds, putting billions of lives in stasis in the process.
----
* ArchEnemy: To Superman, to the point where he goes back in time to destroy his world and prevent his birth. [[spoiler: Except, as it turns out, he never went back in time; his arrival was part of history all along.]]
* BlackEyesOfEvil: His eyes are a solid black with MatrixRainingCode when seen up close.
* BigBad: Of Season One. He was indicated to be this in early [[https://screenrant.com/krypton-tv-show-brainiac-actor/ promotional]] material. [[spoiler: He forms a BigBadEnsemble in Season Two with General Zod and Lobo.]]
* CityInABottle: The first live-action appearance of his city-stealing gimmick. A shrunken city is visible on his ship in one of the first trailers.
* CompositeCharacter: Visually, he's very much based on his post-2008 incarnation (including in the design of his equipment), but apparently he's supposed to be an android like the pre-Crisis incarnation.
* TheCollector: Collects shrunken cities.
* EnemyMine: In the Season Two premiere, he tries to team up with Seg, reasoning that they're both injured and need each other's help. Seg points out that Brainiac would try to kill him as soon as it became convenient, a fact Brainiac doesn't deny, and so decides to just skip the pretense and beats Brainac's body into pulp using a stick. [[spoiler: Unfortunately for Seg, Brainiac survives by putting his mind into Seg's body.]]
* EvilOldFolks: He looks and sounds like an older version of the post-2008 version. [[https://www.youtube.com/watch?v=0WxikiYSnc0 Johns even notes]] that it was important that he appear "ancient".
* EvilSoundsRaspy: His voice is ''very'' raspy and weathered, fitting his incredible age.
* FateWorseThanDeath: He claims that the inhabitants of each city he collects would live forever. That is technically true, however, his idea of eternal life in one of his "bottles" is pretty horrific. Everyone trapped inside is kept in a living stasis, unable to move, never aging, never dying, but trapped in the moment when time froze for them, stuck in place for all eternity...[[AndIMustScream while still completely conscious and fully aware of their surroundings]].
* MakeWrongWhatOnceWentRight: He's come back in time to destroy Krypton and avert Superman's birth. [[spoiler: In fact, Adam Strange is wrong about this. Brainiac was always meant to steal Kandor, which in turn caused the destabilization of Krypton and eventually led to Kal-El being sent to Earth.]]
* OutsideContextProblem: The society of Krypton puts a strict ban on even teaching the possibility that other life exists in the universe. Naturally, they are completely caught off guard when he finally arrives, especially because even for all its advanced technology, Krypton is in the Stone Age compared to the technology Brainiac possesses.
* RoboticPsychopath: An advanced android who destroys planets.
* SatanicArchetype: Fits the role as a harbinger of destruction who is obsessed with having everything under his rule by keeping worlds in bottled containers, essentially creating a "hell" for countless worlds. He also fits in with the Revelations take on Satan: a powerful entity whose arrival brings out the end of a planet's days and is obsessed with ruling his own private collection.
* SuperIntelligence: Standard for Brainiac, and he likes gloating about it.
* TakingYouWithMe: [[spoiler: As he's sucked into the PhantomZone, Brainiac uses his tendrils to drag Seg along.]]
* WhereIWasBornAndRazed: He wiped out his own people after they created him.

-->''"Name's Lobo!"''

A space bounty hunter Seg and Adam Strange bump into.
----
* AmbiguouslyBi: When he's not threatening Seg and Adam, he is commenting on their general attractiveness. He seems to like Adam in particular, referring to him as "a cutie" and "the hot blond". Adam seems genuinely flattered.
* BadassBeard: He sports his iconic goatee.
* BadassBiker: His biker look, which harkens back to his 1990s appearance.
* BigBadEnsemble: He forms this in Season Two with [[spoiler: Brainiac, whom he wants to defeat out of a personal grudge, and General Zod, whom he doesn't care about]] However, he [[DiscOneFinalBoss disappears from the plot]] after [[spoiler: Seg and Adam escape, leaving the expelled Brainiac behind for him to kill]], and when he resurfaces in the finale, [[spoiler: arriving on Krypton after Zod has already been overthrown, he [[EnemyMine forms an alliance with Seg to hunt down Brainiac for good]]]].
* DreadlockWarrior: He sports impressive dreads.
* EeriePaleSkinnedBrunette: True to the comics, his skin is stark gray-white to contrast with his black leather.
* GenreRefugee: ''Krypton'' is a pretty serious sci-fi show overall. Enter Lobo, ''THE'' BloodyHilarious AmusingAlien, in Season 2.
* GutturalGrowler: His voice is usually rather soft and high-pitched, which has never been the case for Lobo before, but it drops into the more familiar growl when he gets especially angry.
* HandCannon: His blaster handgun is ''huge'', yet he's human-sized and uses it with one hand.
* HealingFactor: Getting a basketball-sized hole blown through his torso is a mere inconvenience, as it takes him only a few minutes to regenerate. In the following episode, he shoots his own head off so his body will regenerate from a severed arm on the other side of a forcefield.
* HooksAndCrooks: As in the comics, he uses a chain with a hook.
* RedEyesTakeWarning: He always has them and is most definitely ''not'' someone to be underestimated.
* SkeletonsInTheCoatCloset: He has a skull ornament on his crotch.
* WhereIWasBornAndRazed: He destroyed his own species for laughs. Brainiac then blew up his planet after stealing a city, which really annoyed him because he had the place just to his liking.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/doomsdaykrypton_3.jpg]]
!!! '''Species:''' Mutated Kryptonian
!!! '''Played By:''' Staz Nair (original form)

Doomsday is a monster (or rather, a living weapon of mass destruction) that was created a thousands cycles before the series' present-day as a result of deeply unethical and painful experiments performed by scientists from both the House of El and the House of Zod on a male Kryptonian, Dax-Baron. They initially did so in order to protect Krypton, but then the need faded away and the monster was put into cryostasis due to how extremely dangerous and invulnerable he was. Dru-Zod was convinced Doomsday was the only thing that could stop Brainiac and sought to release him from his prison.
----
* BrainwashedAndCrazy: [[spoiler:Dru-Zod uses a combination of Black Mercy toxin and somatic reconditioning to make him into a loyal tool.]]
* EvilVersusEvil: General Dru-Zod wants to use Doomsday to defeat Brainiac and save the planet, but when Adam Strange reveals that he would kill everyone he finds, Seg convinces Dru-Zod not to use him (or so he thinks).
* HumanPopsicle: Was kept frozen for hundred of years.
* LivingWeapon: Created by the Houses of El and Zod for the purpose of protecting Krypton. Suffice it to say it didn't quite work out that way.
* OmnicidalManiac: It is stated that, if released from stasis, he would kill every living thing on Krypton. After all, he is ''[[NamesToRunAwayFromReallyFast Doomsday]]''.
* NighInvulnerable: His skin soaks up blaster fire with barely a reaction.
* SealedEvilInACan: Let's just say there was a reason Houses El and Zod sealed up their creation instead of using him. He eventually escapes from his containment in the Season 1 finale.
* WasOnceAMan: He was once a Kryptonian soldier named Dax-Baron. He had a unique genetic trait that the Houses of El and Zod exploited to turn him into a living weapon.

!!! '''Species:''' Kryptonians

Black Zero is a clandestine organization that seeks to overthrow the Voice of Rao.

* TheScapegoat: They do exist as a serious threat to Krypton's rulers, but fingers are conveniently pointed at them to throw people off-trail, such as Charys-El and Ter-El declaring themselves Black Zero members to protect Seg while they're on trial or Daron-Vex [[BlatantLies poorly justifying]] his intent to search for Val-El's Fortress of Solitude to Jayna-Zod by saying it contains weapons Black Zero could use. Sentry!Rhom's rampage is also blamed on them (due to a lack of information), although Seg informs Lyta-Zod soon enough about it. Then Daron-Vex plans to frame them for an attack he prepares on the Voice of Rao.
* SuicideAttack: A Black Zero member infiltrated the High Council's room with a bomb hidden in his arm. He tried to detonate it on the Voice of Rao, but Seg prevented him from doing so, since his father was in the room and would have been killed as well.
* YourTerroristsAreOurFreedomFighters: To the reigning order in Kandor, they are clearly terrorists. Meanwhile, they consider themselves as LaResistance against said oppressive order.

The leader of Black Zero.

* AdaptationalHeroism: This version of Jax-Ur is a former healer who fights for equality on Krypton (even though she seems to have no problem with using terrorism as a means to get it) and she aids Seg-El in trying to stop Brainiac. [[spoiler:She also appears to want to help Val-El get Seg back from the Phantom Zone]]. The comic book version of Jax-Ur is a MadScientist and the worst mass murderer in the Phantom Zone.
* AntiVillain
* DefectorFromDecadence: She used to be a member of the council alongside Daron-Vex, but fled when he had Val-El killed, fearing she would be next.
* EyeScream: [[spoiler:In Season Two, Jax-Ur's right eye is replaced with a robotic one that shoots lasers.]]
* GenderFlip: The normally male Jax-Ur is played by the very much female Hannah Waddingham here.
* ProperlyParanoid: Her work on the Genesis Chamber made it sustainable for the foreseeable future, but she also knew that in the wrong hands her methods could be used to further the divide between the Rankless and the Guilded by separating the bloodlines. Sure enough, Daron-Vex did exactly that as soon as he got his hands on her work.
* ThatManIsDead: When Daron calls her "Sela-Sonn" she tells him "My name is Jax-Ur now."
* TortureTechnician: She implants Daron-Vex with a device that causes intense pain at the push of a button, even over vast distances.
* UncertainDoom: After being expelled from the Resistance by Val-El, she's last seen wandering alone in Wegthor's tunnels. It's unknown if she perished with the moon's destruction, or escaped with the others or escaped another way.
* WeUsedToBeFriends: She considered Daron-Vex to be one of her closest friends. However, considering that he tried and executed her mentor Val-El and corrupted her work on the Genesis Chamber to achieve a form of immortality for the Ranked, one might assume that friendship is pretty much dead by now.
* YourTerroristsAreOurFreedomFighters: Black Zero ''has'' resorted to terrorist acts--such as an attempted suicide bombing that would kill innocents just to assassinate the Voice of Rao--but their end goal is to establish true equality on Krypton, free of the caste-based society currently in place.

* GenreRefugee: ''Krypton'' is a pretty serious sci-fi show overall, or at least was in Season One. Enter Lobo, ''THE'' BloodyHilarious AmusingAlien, in Season Two.
