[[folder: John Carter]]

!!John Carter, Prince of Helium, Warlord of Mars
Confederate veteran of the American Civil War, he finds himself transported to Mars through mysterious ways involving astral projecton. Due to the planet's atmosphere and gravity, he is much stronger there than he is on Earth. There, he encounters both formidable alien creatures and various warring Martian races, wins the hand of Martian princess Dejah Thoris, and rises to the position of Warlord of Mars.
* TheAgeless
* AmbiguouslyHuman: Well, he looks, acts, and considers himself human, but there ''is'' the little matter of the immortality...
* {{Badass}}
* BigGood: After becoming the Warlord of Mars.
* BloodKnight: He admits that he enjoys fighting a great deal, although he's quite pacifist compared to the Barsoomians.
* DualWielding: On Barsoom, he adopts the traditional paired long and short swords.
* GrayEyes: Like many other Burroughs' heroes (and pulp heroes in general).
* GuileHero / IdiotHero: An odd combination, depending on context. He's quite clever in a fight, but can often be clueless in social situations, particularly (and self-admittedly) around women.
* {{Heavyworlder}}: Of the second variety - an Earth-normal human on a light-gravity world.
* TheHero: Of the initial trilogy and some of the later books.
* HeroicBSOD: Has one at the end of ''The Gods of Mars''.
* MasterSwordsman: Considers himself one of the best swordsman on two planets; the books show that this is for good reason.
** Though there is one case where he discovers a master swordsman among the Yellow Men who ''was'' a superior swordsman. He had to get clever.
* MightyWhitey: Though he's a human among aliens, rather than a white man among non-whites; also [[HeavyWorlder the mighty part]] is unusually literal.
* NormalFishInATinyPond: On Earth, he's perfectly normal. However, due to lower gravity on Mars, he's superhuman by comparison.
* OutOfFocus: He's the main character of the first three books, then fades into the background for a while so that other characters can take the spotlight, then becomes TheHero again later in the series.
* OutsideContextHero: Carter is this for the rest of Barsoom; an monstrously-strong, nigh immortal juggernaut of a warrior that no one ever faced before in its history.
* SlasherSmile: his "fighting grin" is a heroic version.

[[folder: Red Martians]]
The Red Martians are the most predominant people in Barsoom, originated from the interbreeding between White, Black and Yellow Martians. They are organized into a system of imperial city-states such as Helium, Zodanga, Ptarth and many others. They resemble humans very closely, except for their red-copper skintone and laying eggs instead of giving birth.
!!Dejah Thoris
Princess of Helium and John Carter's LoveInterest. She is repeatedly captured through out the books.
* BreakoutCharacter: She is one of the most recognizable characters among Burroughs' creations and starred her own spin-off ''Warlord of Mars: Dejah Thoris'' under the Dynamite Entertainment's brand.
* {{Deuteragonist}}: In the first book, of which she is the eponymous character.
* DistressedDamsel / DefiantCaptive: She gets kidnapped ''a lot''. Still, while she doesn't usually fight her captors physically, she's generally quick to show her contempt for them. In ''Warlord'', she once has to be knocked out and carried by her captors, as there was no way they could drag her along with them.
* DamselOutOfDistress: Sometimes she can get herself out of trouble, or if nothing else, assist John in doing so.
* EverythingsBetterWithPrincesses
* HappilyMarried: With John Carter.
* HotScientist: Went on a scientific expedition to find and fix the atmosphere factory.
* IHaveYouNowMyPretty: Done to her constantly.
* InhumanlyBeautifulRace: Red Martians are said to be extremely attractive, and many of the villains she attracts belong to different races.
* InterspeciesRomance: With John Carter.
* MsFanservice: Like most female Martians. Hell, its even {{Lampshaded}} by Carter in her first appearance.
-->"She was destitute of clothes (...) save for her highly wrought ornaments she was entirely naked, nor could any apparel have enhanced the beauty of her perfect and symmetrical figure."
* NiceGirl: Dejah is a faithful wife, a caring mother and overall a empathetic and nice person. She managed to push a Thern, [[AlwaysChaoticEvil of all people]], who tried to kill her into perform a HeelFaceTurn.
* OnlySaneMan: By the time of the first book, all Martians are fully aware that the atmosphere will soon be unbreathable. Dejah Thoris is the only political figure interested in any truce to try to prevent this common problem.
* OutofFocus: She has little screen-time in later books than she does in the first book.
* PrincessClassic
* ProudWarriorRaceGirl: In attitude, though she isn't herself a fighter.
* [[GreenSkinnedSpaceBabe Red Skinned Space Babe]]
* RoyalsWhoActuallyDoSomething: She's an incredibly popular political figure in Helium, and she's introduced leading an expedition to test the conditions of Barsoom's decaying atmosphere.
* SoBeautifulItsACurse: Virtually every male BigBad in the first trilogy tries to force her into marriage or rape her.
* WorldsMostBeautifulWoman
* {{Xenafication}}: TheFilmOfTheBook gives her the fighting skills to back up aforementioned ProudWarriorRaceGirl attitude, making her a full-on LadyOfWar.

Son of John and Dejah. He was born the very day his father disappeared from Barsoom.
* AscendedExtra: A supporting character in ''Gods'' and ''Warlord'', he's one of the two leads in ''Thuvia''.
* GadgeteerGenius: Though he only seems to have invented one thing that gets used (essentially, an autopilot for airships). Otherwise an InformedAbility.
* HalfHumanHybrid
* TheHero: Of ''Thuvia, Maid of Mars''.
* LukeYouAreMyFather: In ''Gods'' with Carter, though it takes both an embarassingly long amount of time to realize they're father and son.
* MeaningfulName: Carthoris = Carter + Thoris.
* SuperStrength: Though not to the extent of his dad, he's still stronger and more agile than most Martians.

A young princess of Ptarth that was captured 15 years ago by the White Martians and made their slave. She is freed by Carter when he returns to Barsoom and develops an infatuation to the Earthman. She is the female lead of ''Thuvia, Maid of Mars''.
* AscendedExtra: After being a supporting character in ''Gods'' and ''Warlord'', she gets to be one of the two central protagonists of the fourth book, which is named for her.
* TheBeastmaster: she has the ability to command banths, and uses this frequently.
* DamselOutOfDistress: Somewhat more proactive than Dejah; she shoots and kills a Thern who had abused her and manages to throw off the influence of [[MasterOfIllusion Tario]], who while completely insane was still one of the strongest psychics on the planet. She also kills Salensus Oll along with Dejah and Phaidor.
* EverythingsBetterWithPrincesses: She's the princess of Ptarth, though this isn't immediately revealed.
* FriendToAllLivingThings: Well, all banths, anyway. Its said she always had a way to deal with them ever since she had one as a pet when she was a child. She doesn't understand this ability any better than everyone else.
* LoveFatherLoveSon: She initially showed attraction towards Carter, but eventually got over him when she realized he was faithful to his wife. She settled for their son, Carthoris, in her own spin-off book.
* LovingAShadow
* PsychicPowers: Beyond the usual subtle telepathy of Red Martians, she can communicate with and control banths.

!! Tara of Helium
Daughter of John and Dejah and younger sister of Carthoris.
* HalfHumanHybrid
* HelloNurse: She has inherited her mother's extreme beauty, and many men are willing to ignore her less than appealing personality flaws because of it.
* NervesofSteel: She inherited her father's resourcefulness and resolve.
* RoyalBrat
* SpoiledBrat
* SurvivalMantra: "I still live"--learned from her father.
* WellExcuseMePrincess

!! Kantos Kan
A Jedwar (Captain) in Helium's army.
* TheLancer: To Tardos Mors.
* TheReliableOne

!!Tardos Mors
Dejah Thoris' grandfather and Jeddak of Helium.
* BadassGrandpa
* BigGood: He served this role prior to John ascending as Warlord of Mars.
* TheGoodKing: He is regarded as the noblest and greatest of all Jeddaks among the Reds.
* MadeASlave: While under [[EvilOverlord Salensus Oll]]'s captivity.
* ProudWarriorRaceGuy

!! Tan Hadron of Hastor
The main protagonist in ''A Fighting Man of Mars'', Hadron is a officer in Helium's army who embarks in the search of his beloved Sanoma Tora.
* BadassNormal: Compared to [[OutsideContextHero John Carter]], [[HeavyWorlder Ulysses Paxton]] and [[HalfHumanHybrid Carthoris]], Hadron is just an average Red Martian soldier that lacks SuperStrength like other main protagonists of other books and also several times more vulnerable than they are, which makes all his feats of bravery even more impressive.
* ImpoverishedPatrician: Hadron is technically a prince of Gathol through his mother side, but he doesn't enjoy any special privileges, not that he minds it initially though it frustrates him because Sanoma Tora won't spare a thought about him due to his station.
* TheHero: In ''A Fighting Man of Mars''.
* HumbleHero: Hadron is quite comfortable with his humble life as a padwar in Helium's army.
* LovingAShadow: He is infatuated with a idealized version of Sanoma, projecting many virtues that [[RichBitch the]] [[DirtyCoward real]] [[UngratefulBastard deal]] lacks. He grows out of it when he sees
* ObliviousToLove: Hadron doesn't realize he fell in love with Tavia until late in the story.
* SheIsNotMyGirlfriend: He just considers Tavia a good friend. [[SarcasmMode No really.]]
* SurvivalMantra / BadassBoast: He also uses John Carter's "I still live."

!! Tavia
* ActionGirl: Compared to most Barsoomian heroines, Tavia is more hands-on, directed to combat and more likely to free herself if captured.
* BadassPrincess: The one most deserving of the title.
* BattleCouple: With Hadron.
* [[BettyAndVeronica Betty]]
* BoyishShortHair: She is described as having cropped, short hair.
* EverythingIsBetterWithPrincesses: In a unsurprising turn of events, Tavia reveals she is actually a princess.
* DamselOutOfDistress: In a sharp contrast to Sanoma Tora.
* {{Deuteragonist}}: In ''A Fighting Man of Mars''.
* DeadpanSnarker
* MadeASlave
* PluckyGirl
* SweetPollyOliver: She escaped from Tul Axtar's harem by disguising herself in male warrior trappings.
* TomboyPrincess: Though its not initially established she is an princess, Tavia is definitely a tomboy. In fact, she is deemed too masculine-looking for Axtar's tastes and he strands her alongside Hadron, rather than adding her to his harem (much to Hadron's relief).

!!Sanoma Tora
* AlphaBitch
* BeautyIsBad: Tora is extremely beautiful and alluring, but these are pretty much her only redeeming traits.
* DirtyCoward
* DistressedDamsel: Being captured by [[BigBad Tul Axtar]] and added to his harem is what kicks off the events of ''A Fighting Man of Mars'' as Hadron goes to rescue her. In a unusual turn of events, she betrays her rescuers and sides with her kidnapper.
* RomanticFalseLead: To Hadron.
* RichBitch: Her father is a NouveauRiche, who is merely distinguished by his immense wealth than any other quality.
* UngratefulBitch: Hadron spends the book searching for her out of love, to prevent her from being made Axtar's concubine and manages to save her and imprison her captor. How does Sanoma repays? She basically sells Hadron and Tavia out by siding with Tul Axtar when he promised to make her his Jeddara if she released him. In her defense, she convinced Axtar to merely maroon Hadron and Tavia in a savage land instead of outright kill them out of mercy.
* UptownGirl: She is this to Tan Hadron at first. While he has BlueBlood himself, he is neither rich or privileged - He is identified rather as a lowly, poor padwar (army officer) than a chieftain and as such Sanoma looks down on him, which is ironic given his background, he would stand higher than her due to him being a prince and her being merely a noblewoman from a recently ascended family.
* [[BettyAndVeronica Veronica]]

!!Tul Axtar
Bent on conquering the world, Tul Axatar caused several advanced war products to be developed which would make victory guaranteed; disentegrating rays, cloaking devices, millions of starving warriors. He also had a harem of thousands of women kidnapped around Mars, with Sanoma Tora as the newest addition.
* BigBad: In ''A Fighting Man of Mars''.
* DirtyCoward: Even compared to other villains in Barsoom, Axtar stands out. He postpones his conquest of Barsoom out of fear, despite having all advantages at his disposal such as superior weaponry that nobody can match and surprise. Whenever he is backed into the corner by [[TheHero Hadron]], he is utterly terrified.
* EvilOverlord: Rules his kingdom of Jahar with iron fist, regularly kidnaps beautiful women for his harem and has plans of conquering Barsoom.
* IHaveYouNowMyPretty: Does this to Sanoma Tora. Would have done it to Tavia too, but she took measures to make herself look unappealing enough for him to leave her alone.
* TakeOverTheWorld: His ultimate plan.
* WeCanRuleTogether: Makes this offer to Sanoma.

!!Phor Tak
Originally from Jahar, this ancient scientist fled Tul Axtar's oppressive influence and relocated at a white castle he named Jhama. He is the creator of the disentegrator ray, the invisiblity paint, and "the flying death," a smart bomb.
* TheDragon: He was originally this to Axtar.
* EnemyMine: He forms an alliance with Hadron to help against Axtar, though its clear that Phor Tak is just as evil and also wants to take over Barsoom.
* EvilLaugh: Has a very distinctive cackle that sounds like "Heigh-oo"
* MadScientist: He created fearsome disintegrating rays that are capable of dissolving ships effortlessly.

* AnimalMotifs: Spiders. He has then adorned in his inner quarters and then there is his nickname.
* BeardOfEvil: Unusual in Red Martians, since they are said to lack facial hair.
* TheCaligula: Even more so than Tul Axtar.
* ColdBloodedTorture: His favored pastime.
* KarmaHoudini: After the heroes escape him, Ghron is never mentioned again and therefore never faces any punishment or repercussions for his actions.
* TortureTechnician
* TheRedBaron: The Spider of Ghasta

!! Ras Thavas
* CreatingLifeIsBad: Ras Thavas discovers this the hard way when he creates the Hormads.
* GrandTheftMe: specializes in this, and has his student, Vad Varo, do it for him.
* GreyAndGrayMorality: he is one of the few charactes in the books who is not clearly good or bad, but rather somewhere in between. He does do morally quastionable things, yet he also uses his skills as a surgeon to help people.
* MadScientist: swaps peoples minds for money and later creates an army of synthetic creatures.
* TinMan: Ras Thavas, just like the Toonolians, appears to have reached this state from excessive desire to be TheStoic. He professes to be above such things as sentiment, but when he manifests it, and Ulysses Paxton calls him on it, he is in complete denial.
* TurnedAgainstTheirMasters: he falls victim to this with the Hormads.

!!Valla Dia
* GrandTheftMe: She falls victim to this.
* SoBeautifulItsACurse: Warriors used to fought over to claim her. She is perfectly fine with having her body switched with a old hag if it means no more people dying because of her.

* BigBad: In ''Master Mind of Mars''.
* EvilOldFolks: Just like Issus, Xaxa is extremely old and looks like it. Given how slowly Martians age, she must be centuries old.
* GodSaveUsFromTheQueen: She is said to have cruelly taxed and exploited her citizens and used the fear of their deity to keep them from rebelling.
* GrandTheftMe: She switched bodies with Valla Dia.

!!Sab Than
* AndNowYouMustMarryMe: Or you precious home will fall.
* ArrangedMarriage: With Dejah Thoris.
* BigBadEnsemble: With Tal Hajus in ''A Princess of Mars''. He is the final obstacle to be overcome in the first book.
* FlatCharacter: There isn't much to his character other than being a Prince of Zodanga (the rival city-state to Helium) and forcing Dejah to marry him and secure peace between the two.
* SpeakNowOrForeverHoldYourPeace: The marriage ceremony is crashed by Carter with an army of Tharks. According to Martian customs, a woman cannot marry the man who murders her husband or groom. [[spoiler: The problem is settled when Tars Tarks is the one to kill Than instead of Carter.]]


[[folder: Green Martians]]
The other most predominant race in Barsoom, the Green Martians are a nomadic, primitive race of green-skinned humanoids with two pair of arms. They are extremely warlike and brutal, pretty much being [[OurOrcsAreDifferent orcs]], as they frequently raid Red Martians and are [[TheUsualAdversaries the most common foes battled by the main heroes]], with the exception of the Tharks, who become allied to them from the end of first book on.
!!Tars Tarkas
A Thark warrior who is the first being to befriend John Carter when he first sojourns on Mars. He is Carter's most valuable ally and his blood brother, having become Jeddak of the Tharks with his help.

* AsskickingEqualsAuthority
* {{Badass}}
* BloodKnight: Like most Tharks.
* BashBrothers: He's Carter's best Martian friend and probably the best warrior on the planet after him- if they're fighting together, well, you don't want to be a {{mook}}.
* TheLancer
* KlingonPromotion: He becomes the new Jeddak by killing the previous one, [[CurbStompBattle not that it was that hard]].
* MultiArmedAndDangerous
* MySpeciesDothProtestTooMuch: He is noted for being too noble and honorable for a Thark. His daughter Sola shares the same trait.
* Out of Focus: From the third book onwards, Tars rarely appears again.
* ProudWarriorRaceGuy

!!Tal Hajus
Jeddak of the Tharks in ''A Princess of Mars''.

* AsskickingEqualsAuthority: Subverted. He must have been a powerful warrior in his youth to win his throne, but by the time he shows up in-story he's gone ''badly'' to seed.
* ArchEnemy: To Tars Tarkas
* BigBadEnsemble: With Sab Than in ''A Princess of Mars''. He is the initial antagonist during the book's first half.
* TheCaligula
* CurbStompBattle: When Tars challenges him, Burroughs doesn't even bother ''describing'' the fight. Tars wins ''that'' effortlessly.
* DirtyOldMan: He has absolutely no compunctions about forcing himself on Dejah or Sola.
* FatBastard
* OrcusOnHisThrone: He is too bloated and degenerated to even move, let alone fight.
* VillainousGlutton

!! Sola
* TheChick: for whatever weight the term holds on Barsoom.
* EstablishingCharacterMoment: when she provides a ComfortingComforter for John Carter.
* LukeYouAreMyFather: Tars Tarkas is her father. Most Green Martians don't know either parent.

!! Sarkoja


[[folder: Black Martians "The First Born"]]
Referred to as the very first race of men in Barsoom, the Black Martians trace their origins to 23 million years in the past, being the very first people to break from their egg shells. The First Born are a proud people who live to fight and are loathe to work, relying on slaves for nearly everything except warfare. They are also a very religious people who worship Issus, the Living Goddess, a deity that is honored throughout in Barsoom, but they are directly controlled by her. The Black Martians were infamous raiders that frequently targeted Valley Dor, capturing Thern and Red Martian females.
The Supreme Deity of Mars, she is in reality an very ancient female Black Martian.
* AGodAmI
* BigBad: Of ''The Gods of Mars''
* DoWithHimAsYouWill: Carter leaves Issus at the mercy of her subjects after exposing.
* ElderlyImmortal: Martians are said to be TheAgeless, yet Issus clearly shows signs of age. She is probably ''that old''.
* [[GodEmperor God Empress]]
* GodSaveUsFromTheQueen: Issus ruled over her kingdom with iron fist, had female slaves regularly sacrificed to her for no reason but to glorify her "divinity".
* HoistByHisOwnPetard: She was butchered by her own people after Carter revealed she was nothing more than an crazy old woman.
* IAmHumanitarian: After a year or so, Issus devours her handmaidens.
* TheManBehindTheCurtain: When actually confronted, she's revealed to be powerless.
* PsychicPowers: Part of how she maintains the fiction of her divinity; most Martians are mildly telepathic, but the ability is unknown among the First Born- except for her. Carter recognizes what it is almost immediately, though.
* TimeAbyss: How old is she said to be is not stated, but judging by how long Barsoom venerated her as a goddess, its believed she is over hundreds of thousands years old.
* VillainousBreakdown: Issus gradually looses her sanity after having her will defied by John Carter. When he has the crone at his mercy, she had gone so off the deep end that it even disturbed him.
-->''And then it was that she went mad. A screaming, gibbering maniac writhed in my grasp. It bit and clawed and scratched in impotent fury. And then it laughed a weird and terrible laughter that froze the blood. The slave girls upon the dais shrieked and cowered away. And the thing jumped at them and gnashed its teeth and then spat upon them from frothing lips. God, but it was a horrid sight.''


* DefectorFromDecadence: He renounces Issus once she realizes she is not all-powerful as he was lead to believe.
* DefeatMeansFriendship
* FireForgedFriends: He and Carter start out enemies, but become allies after being imprisoned in Issus' dungeons together.
* MySpeciesDothProtestTooMuch: At first, he's the only sympathetic Black Martian.
* NobleDemon
* ProudWarriorRaceGuy
* WorthyOpponent

!! Thurid
A First Born Dator that first appeared in the second book to humiliate Xodar after he had fallen from grace. John defends Xodar by knocking out Thurid and severely wounding his pride. He joined forces with Matai Shang in ''Warlord of Mars'', providing him with a secret entrance to the Temple of Issus where his wife Dejah Thoris is imprisioned, motivated to absolutely hurt the Earthman for humiliating him.

* AscendedExtra: In ''Gods'' he appears in one scene, where all he does is get badly beaten by Carter. In the next book, ''Warlord'', he's one of the main villains.
* BigBad: Of ''Warlord'', with Matai Shang and Salensus Oll.
* TheBrute
* MasterRace: He's a First Born. It's their thing. Not that it stops him from lusting after females from "lesser races".
* ProudWarriorRaceGuy
* RedOniBlueOni: With Matai Shang; he's red. He's a HotBlooded warrior motivated primarily by a desire for revenge.
* RevengeBeforeReason: He ''hates'' Carter for humiliating him in front of Issus' court.
* TeethClenchedTeamwork: With Matai Shang.
* YouHaveOutlivedYourUsefulness: He backstabs Matai Shang when the Thern's last plan goes belly-up. Of course, Thurid himself dies minutes later when Phaidor [[AvengingTheVillain Avenges the Villain]].
* VillainousCrush: Towards Dejah Thoris.

[[folder: White Martians (Therns)]]
The White Martians are the {{Precursors}} in Barsoom's history. Its said they ruled Mars over 500.000 years ago as a seafaring culture, but their empire degenerated over the years after the oceans started to dry up. Their descendants still live to this day as reclusive beings split into two races: the '''Therns''', who inhabit Valley Dor and keep an complex PathOfInspiration to lure other races to be enslaved and devoured, and the '''Lotharians''', a DyingRace of very powerful psychics who spend their time debating philosophy among themselves. White Martians resemble Caucasian humans with blonde hair, though the Therns are actually bald and wear wigs to cover themselves.
!!Matai Shang, "The Father of Therns"
Holy Hekkador (High Priest) of the Therns.
* AGodAmI
* ANaziByAnyOtherName: Strange aversion. He's a blue-eyed, blond-haired (well, blond-wigged), white-skinned man who believes himself superior to other races and therefore has the right to exploit them however he sees fit and has a cult of followers who believe the same- but at the time ''Gods'' and ''Warlord'' were written, nobody had heard of a Nazi. OlderThanTheyThink?
* BaldOfEvil / BlondGuysAreEvil: Like all Therns, he's naturally bald but wears a wig to cover it up.
* BigBad: Of ''The Warlord of Mars'', shared with Thurid and Salensus Oll
* TheChessmaster
* ColdBloodedTorture: He and Thurid agreed to inflict any vileness they could think on John Carter's princess.
* EvilGloating
* HeWhoMustNotBeSeen: In ''Gods'' he's mentioned a lot but never shows up in the flesh. This changes in the first chapter of ''Warlord''.
* ImAHumanitarian: A Thern of his rank only eats the flesh of Red and Green Martians.
* IHaveYouNowMyPretty: He says it to Carter's face this is what he intend to do with Dejah after killing him.
-->''(...) But that the death you die tonight may be doubly bitter, know you that when you have passed, your widow becomes the wife of Matai Shang, Hekkador of the Holy Therns, for a Martian year. At the end of that time, as you know, she shall be discarded, as is the law among us, but not, as is usual, to lead a quiet and honored life as high priestess of some hallowed shrine. Instead, Dejah Thoris, Princess of Helium, shall become the plaything of my lieutenants--perhaps of thy most hated enemy, Thurid, the black dator."''
* PriestKing
* RedOniBlueOni: With Thurid; he's the blue. He's a cold-blooded schemer who stays away from the action and is mostly motivated by a desire to maintain his power.
* SmugSnake
* TeethClenchedTeamwork: With Thurid; they hate each other, but hate Carter more.
* TryToFitThatOnABusinessCard: Matai Shang, Holy Hekkador of the Holy Therns, Father of the Therns, Brother of Issus, Master of Life and Death Upon Barsoom.

Matai Shang's daughter, she was introduced into being captured by the First Born.
* AGodAmI
* AlasPoorVillain: Carter and Dejah are legitimately moved and grieved at her death.
* AntiVillain: While she's not a very good person, and has all the character flaws of your average thern, she's genuinely in love with John Carter and ObliviouslyEvil for most of her life.
* AvengingTheVillain: Part of why she kills Thurid- at the very least, his murder of her father was the immediate provocation.
* BaldWoman / BlondesAreEvil: Like her dad, she's a Thern, and therefore naturally bald hidden by a blonde wig.
* DaddysLittleVillain: To Matai Shang.
* DrivenToSuicide: After her HeelRealization, invoking DeathEqualsRedemption.
* EvilCannotComprehendGood: About half her dialogue to Carter involves expressing bafflement about why he does the things he does (the other half is her admitting she's attracted to him anyway).
* HeelRealization: At the end of ''Warlord''. After seeing the lengths Carter is willing to go to rescue Dejah, she realizes how shallow and selfish her own life and love for Carter has been.
* MsFanservice
* ObliviouslyEvil: It's clear that, even more than your average thern, Phaidor simply does not get why being a [[ImAHumanitarian cannibalistic]] [[AGodAmI would-be goddess]] or attempting to MurderTheHypotenuse would be a bad thing. She suffers a HeelRealization when she can't deny it anymore.
* ShadowArchetype: To Dejah.
* VillainessesWantHeroes
* WomanScorned: Let's just say that princesses of races of creepy mystics with god complexes don't take rejection very well...

* AsskickingEqualsAuthority: Rather unusually for White Martians, Tario is regarded as the most powerful mind among the Lotharians.
* EvilOverlord: Of the Lotharians.
* HypnotizeThePrincess: Literally tried to pull this on Thuvia.
* IHaveYouNowMyPretty: Tario attempted this on Thuvia of Ptarth. It ended badly for him. Komak reveals that Tario was attempting to materialize a beautiful girl to serve as this purpose.
* MasterOfIllusion
* TheNeedless
* PsychicPowers: All Martians possess it to some degree, but the Lotharians have it to the extreme and Tario is considered the most powerful of them all.
* RealityWarper
* YourMindMakesItReal

!!Kar Komak
* TheLancer: To Carthoris during ''Thuvia, Maid of Mars''.
* MasterOfIllusion
* MySpeciesDothProtestTooMuch: He is the only fully sympathetic White Martian, unlike Phaidor who is introduced as a villain and performs a late HeelFaceTurn followed by RedemptionEqualsDeath, Komak on the other hand is heroic from beginning to end.
* NobleTopEnforcer: To Tario before rebelling.
* RealityWarper: He gains this ability later, being able to create his own construct-bowmen.


[[folder: The Yellow Martians]]
Believed to have been wiped out by the Green Martians thousands of years ago, the Yellow Martians of Okar still live as recluses in the North Pole. They kept themselves hidden using their technology to bring down any ship or vehicle that came near, and due to the extreme conditions of their land, travel on foot is considered impossible. They lived under [[DomedHometown domed cities]] that protected them from the extreme cold, and the only two know city-states to exist are Kadabra and Marentina. Yellow Martians are noted for being very large and powerfully built as well as sporting beards.
!!Salensus Oll
Jeddak of Okara, seated on the city of Kadabra.
* AndNowYouMustMarryMe: ''In Warlord of Mars'', he declares that Dejah Thoris shall become his queen after having her husband executed.
* AuthorityEqualsAsskicking: Defied. We explicitly never learn how good a fighter he is; Carter, motivated by ThePowerOfLove for Dejah, kills him before he even lands a blow.
* BigBad: Of ''Warlord'', with Matai Shang and Thurid.
* EvilOverlord: Of the Yellow Martians.
* EvilUncle: To Talu.
* LargeAndInCharge: He's a huge, imposing man.
* SuspiciouslySimilarSubstitute / SequelEscalation: In his role in the story, he's basically a bigger, meaner version of Sab Than from the first book.
* ZeroPercentApprovalRating: His own people largely hate him, except for his warriors who are loyal.

Oll's rebellious nephew, he is the Jed of Marentina.
* RebelLeader: Against his uncle's rule.
* TheWisePrince: He provides Carter his support into helping rescuing his wife. The Okarans prefer him over his uncle as well.

Though he appears to be nothing more than a mere, old Yellow Martian lackey, Solan is a fearsome swordsman, arguably the best challenge faced by Carter in ''any'' of the books.
* BadassGrandpa: He's a tiny old man, but don't underestimate him.
* EliteMook: What he amounts to story-wise, though it doesn't quite do him justice.
* MasterSwordsman: Considering he's able to overcome the advantage of Carter's super-Martian strength, he's probably the more skilled of the two by a fair margin. ''Let that sink in''. He was almost certainly the best swordsman on Mars.
* WorthyOpponent: Carter himself regrets that no one witnessed their duel because of how impressive they both were.

[[folder: Other Characters]]

* AllAnimalsAreDogs: Woola is a calot, the Barsoomian equivalent to a dog.
* BadassAdorable
* BecauseYouWereNiceToMe: Woola used to be an guard dog for Tharks and mistreated all his life. After Carter saved him from a white ape, Woola became fiercely loyal to the Earthman.
* BigFriendlyDog
* UndyingLoyalty: To John Carter and his family.

* AliensAreBastards: Bandolian is a invader from Jupiter (or as Martians call it, Sasoom) and quite the {{Jerkass}}.
* BigBad: Of ''Skeleton Men of Jupiter''.
