Voiced by: Miyuri Shimabukuro (JP), Nai Br.XX (Singing), Jeannie Tirado (EN), Harumi Nishizawa (MEX)
An outgoing orphaned girl trying to survive in Alba City doing multiple (and short-lived) part-time jobs. She meets with Tuesday when playing keyboards in the streets.
- Ambiguously Brown: She's black and is from Earth, but her exact ethnicity is unknown.
- Bare Your Midriff: Some of her outfits, including in the first ending credits, show off her waist.
- Berserk Button: Calling her ugly. Even as a kid, she would beat people up for that.
- Beware the Nice Ones: Carole is a sweet girl but doesn't take shit from people who try to look down on her, over-spicing the food of a customer at her restaurant who tries to have her "serve" him with obvious lewd intentions and is ready to throw down with a group of guys harassing Tuesday.
- Evil Chef: How she lost her job as a waitress at "Big Jump Burger": One of the customers made an unreasonable complaint about the coffee's bitterness in a rude way and another was demanding she'd service him sexually and called her ugly when she refused, so she served them both hamburgers with a giant overdose of some kinda sauce that made them scream with disgust or pain.
- Doorstop Baby: She was abandoned by her parents on the steps of a church.
- Generic Cuteness: She is supposedly rather plain, and is at times even referred to as "ugly", but her character design makes her look on par with Angela, who is a model. Maybe this is why she is hoisted in work overalls ever so often.
- Limited Social Circle: Carole doesn't seem to have a lot of friends, if any (outside of Tuesday), which is a bit odd considering her bright and outgoing personality.
- Meaningful Name: Her name is "Carole" and she was born on Christmas Day.
- New Job as the Plot Demands: Played for Laughs. Her first appearance shows her being fired from a fast food restaurant after sabotaging the orders of two rude customers. She spends most of her time trying to hold down another job before promptly losing it.
- Nice Girl: She is overall nice, inviting and patient, which largely contributed to her bonding with Tuesday.
- Odango Hair: Flashbacks show that she used to have this hairstyle as a child, and a boy even teased her by calling her "odango atama" ("dumpling head") in the Japanese track.
- Starving Artist: Along with Tuesday, while successful, the girls never seem to catch a break. Even after winning Mars Brightest, Gus declines the contract they're offered and even by the series end when they're nominated for a Grammy, are still living in Carole's landlord's former storage room. The landlord's comments near the end suggest that Carole can afford to move out of the old storage room but just wants to stay a bit longer.
- Tomboy and Girly Girl: The outgoing and feisty tomboy to Tuesday's sweet and timid girly girl.
- Tomboyish Ponytail: She typically wears her hair in a ponytail, distinguishing her as more tomboyish than Tuesday.
- Tomboy with a Girly Streak: While she is often depicted wearing her trademark overalls, she also dresses up in more "girly" attire like short skirts, knee socks and shoulder-baring blouses, especially when performing.

The daughter of a rich family (her mother is a famous politician) who ran away from home in the hope of becoming a musician in Alba City. Unlike Carole, she's rather timid and clumsy. She plays an acoustic guitar she calls Hummingbird.
- 10-Minute Retirement: Forced into one when her mother has her kidnapped and forced back home in an attempt to stop her from undermining Valarie's political career. Carole and her brother Spencer make a point of breaking Tuesday out within an episode.
- Affectionate Nickname: Carole takes to calling her "Tue". So does Cybelle.
- Ambiguously Bi: Tuesday is clearly attracted to Kyle and is very upset when she discovers that he has a girlfriend, but she has a plethora of Ship Tease moments with Carole as well, referring to feeling alive being with and performing music with the latter and is comforted about Kyle with a Cooldown Hug from her, crying into her shoulder.
- Beware the Nice Ones: While she is overall very nice, when she and Carole go to meet Ertegun who insults their music without even listening to it, Tuesday quietly burns her letter... inside Ertegun's house, activating the sprinklers with everyone still inside. Like Carole, she's shocked at what she did.
- Fish out of Water: Has never been to the big city before, and shortly after she arrives, her suitcase with most of her belongings gets stolen. Later when Carole goes off to find another job, she tries to clean up, only to make the place even messier than before. She also knows very little about the music industry, frequently reacting to Gus' mentions of legendary figures with, "Never heard of them".
- Generic Cuteness: Described as plain-looking, she still makes a striking impression with her slender frame, long hair and fashion sense. Even her Youthful Freckles can't hide the fact that she would be considered rather dashing in real life.
- Girly Run: Tuesday runs this way when trying to get the Mars Brightest Stage on time in episode 12.
- Lonely Rich Kid: Heavily implied to not have had any meaningful friends or relationships when growing up as a rich girl, to the extent her first song with Carole is even named "The Loneliest Girl".
- Love Hurts: She finds herself utterly shocked when she realizes her crush on Kyle is unrequited since he already has a girlfriend.
- Meaningful Name: Her name is Tuesday, and the series is set on post-colonization Mars. In numerous cultures, the day Tuesday is associated with the planet Mars.
- Not a Morning Person: Tuesday clearly isn't used to waking up early.
- Pimped-Out Dress: While she does have some casual outfits, cute or elegant, frilly Lolita-style dresses are a big part of her wardrobe. Give her a nice parasol and she wouldn't look out-of-place showing off in Harajuku.
- The Runaway: In the first episode, she runs away from home to Alba City since her family doesn't approve of her dream to become a musician.
- Starving Artist: Along with Carole, while successful, the girls never seem to catch a break. Even after winning Mars Brightest, Gus declines the contract they're offered and even by the series end when they're nominated for a Grammy, are still living in Carole's landlord's former storage room.
- Sheltered Aristocrat: Unlike the streetwise Carole, she starts off as being very sheltered, both due to her background as the daughter of a rich politician and her extreme shyness preventing her from getting out much before she decided to run away.
- Shrinking Violet: Unlike Carole, she's timid and doesn't have much self-confidence. She mentions that her shyness eventually became too much for her and she stopped going to school because of it.
- Tender Tears: Tuesday is easily overwhelmed by stress or despair, which leads to plenty Cry Cute moments.
- Tomboy and Girly Girl: The sweet and timid girly girl to Carole's feisty and outgoing tomboy.
- Youthful Freckles: Has very faint freckles, and she's naive and is one of the youngest of the cast.

A successful model who decides to take up singing to add more to her fame.
- Addled Addict: After Dahlia gets hospitalized and she finds out they aren't actually related, Angela turns to drugs, and rapidly grows unstable. During her Grammy performance, she has Exhausted Eyebags under her eyes as she sings, and everyone in the audience seems to notice something's off about her. Within seconds of finishing her song, she collapses onstage and is quickly wheeled to the hospital.
- All Love Is Unrequited: Seems to have a crush on Tao, who remains coolly professional and impassive.
- Ambiguously Brown: She is dark-skinned (possibly black), but she has no particular ethnicity mentioned in-series.
- Attention Whore: The real reason Angela wants to be a singer is for the popularity, implied to be a means to make up for her tragic childhood. This may be why she tries to flirt with Tao.
- Bad Boss: Angela goes through a lot of managers, either by firing them at the drop of a hat or bullying them until them quit. She refuses Dahlia's suggestion that they use AI managers, specifically saying she wants a person to boss around.
- Bare Your Midriff: Her casual clothes occasionally show her navel, fitting her role as a popular and attractive model-turned-singer.
- Dark and Troubled Past: Episode 7 heavily hints that Dahlia was physically abusive to her when she was younger. Angela even says being in her old house feels like she is suffocating.
- Earn Your Happy Ending: Angela was abused by Dahlia as a kid and seems to have largely grown up friendless. In the last episodes, she is put through the emotional ringer: Dahlia passes away after revealing they're not related, and Angela has to be hospitalized from a drug overdose. It's only after she has lost the will to sing that Angela overcomes her pride, and performs at Carole and Tuesday's illegal concert. By doing this, Angela makes new friends and gains the love she always wanted.
- Even the Girls Want Her: Each time she enters the stage the focus is on her female fans.
- Everyone Has Standards: She might wish to win Mars' Brightest and claims to hate Carole and Tuesday's music, but is incensed when she finds out someone tried to sabotage Tuesday. So much that she even fires Katy, believing she's responsible, and stands up for Carole and Tuesday when the judges initially refuse to let them perform since they arrived late.
- Former Child Star: She had a very prolific career as a child, but is now in a bit of a rut as she moves into adulthood.
- Freudian Excuse: It's heavily implied she's got her own history and issues which makes her difficult personality sympathetic.
- Hero of Another Story: Where the main pair of protagonists are fighting their way to the top, Angela is a former child star with a lot of baggage, surrounded by frenemies, working to keep from getting tossed aside by society. She even gets her own impressive victory scenes.
- Jerk with a Heart of Gold: She's rude and can be conceited, but she wants to play fair and respects her opponents, preferring to beat them at their best.
- Nice Character, Mean Actor: Angela puts on a perky façade for the camera, but she's really jaded and cold.
- Not So Different: It's incredibly difficult not to sympathize with her as much as the main characters. Both her arc and the main pair's arc mirror each other in a lot of ways.
- The Resenter: Admits to having resented Carole and Tuesday in the finale, but has gotten over it by that point.Angela: I figured out why I hate your music so much. It reminds me of the time when I could still enjoy singing.
- Teeth-Clenched Teamwork: She clearly dislikes working for the callous Tao (and even after she's warmed up to him she still finds him annoying at times), but because of his success at promoting other artists, she sucks it up and agrees to his demands. Her patience does have limits, though.
- The Ugly Guy's Hot Daughter: Well, Dahlia used to be better looking, but their daughter Angela looks a lot more lovely.
- Worthy Opponent: She comes to see Carole and Tuesday as good rivals by the finals of Mars' Brightest.

A man struggling in the music business who used to manage a couple of musicians. He immediately goes to Carole and Tuesday after watching a viral video of their performance of "Loneliest Girl", making himself their manager in hopes of helping them become big.
- Alas, Poor Villain: Downplayed with a rival that Gus doesn't get along with. He is noticeably upset when Dahlia passes away, to the point that he can't even bring himself to attend the funeral, although he does visit their grave later and laments that they won't get to see Carole and Tuesday's underground concert.
- The Alcoholic: Not having a new success in years led him to spend most of his days drinking at a bar. Him ordering a cola is enough for his bartender to quickly become very concerned.
- Alliterative Name: Gus Goldman.
- Formerly Fit: In pictures and flashbacks, he was quite lean and good-looking a couple of decades ago.
- Papa Wolf: Despite all the comedy with his incompetence handling the girls, he genuinely does care for them. When someone burns Tuesday's hand with dry ice, he angrily says he'll punish whoever is responsible.
- Sitcom Archnemesis: Develops an almost immediate dislike of Dahlia, and two interact in hilariously petty ways.

An acquaintance of Gus. His video recording of Carole and Tuesday's performance of "Loneliest Girl" goes viral after he uploads it. Afterward he joins Gus in helping Carole and Tuesday become professional musicians.
- Brainy Brunette: Brown-haired and is much more technologically savvy than Gus.
- Butt-Monkey: Usually gets the short end of the stick when it comes to Gus' schemes.
- Hyper-Competent Sidekick: Technically, Gus is in charge of getting Carole and Tuesday's career off the ground, but Roddy's usually the one getting them equipment, publicity, and gigs.
- Meaningful Name: Roddy's name sounds like "roadie". It does not quite apply, since he's actually a sound engineer, but it's close enough.
- Otaku: Hinted at. He has a collection of mech figurines that he treasures, and when thinking of ideas for Carole and Tuesday's first music video, he's insistent that it be animated.
- Peek-a-Bangs: His hair always covers his right eye, perhaps to portray his shyness.

Angela's parent and agent. Has been pushing their daughter in their career since she was a child.
- Ambiguous Gender: While Dahlia refers to themselves as Angela's mother and Angela calls them "Mom", Tao reveals in episode 5 that they have a condition called "Martian Androgyny", which probably explains their surprisingly deep voice. Word of God on the anime's website is that the Martian environment gives Dahlia shifting characteristics of both sexes, and the site refers to them with gender-neutral pronouns. A photo from Angela's old room shows them with a much more masculine appearance (minus their current hair, dress, and heavy makeup).note
- Character Death: Dies in Episode 22, after being hospitalized for a heart attack.
- Gonk: Dahlia is huge, overweight, and looks less appealing than other characters.
- Spell My Name with an "S": Although Dahlia is the official spelling from official sources, a vitals monitor in the hospital spells it "Dharia".
- Troubled Abuser: Episode 7 implies Dahlia's stress over their Male-to-Female transition as well as poorly prescribed medicine drove them to verbally and physically abuse Angela as a child. While Dahlia is contrite and the mother and daughter's relationship has gotten better by the present, Angela still can't abide the memories in her childhood home.
- Vicariously Ambitious: Dahlia was a child star that fell into obscurity by their twenties. Now they're pushing Angela to achieve the stardom they dreamed of. Angela has always been aware of what drove her mother's encouragement, and finally calls them out for it in episode 20.
- You Gotta Have Blue Hair: Purple hair. It used to be brown.

A successful music producer. He helps kick-off Angela's music career by writing her songs with his A.I.
- Aloof Big Brother: Behaves this way towards Angela, who constantly seeks his approval after he takes her under his wing while he acts caring bus distant towards her and the finale reveals they are both designer babies created by the same scientist.
- Brutal Honesty: When he first meets Angela, he wastes no time telling her that working with him means becoming his puppet. He is also very open about how he prefers the company of A.I. over people and how he doesn't care about what Angela thinks of him.
- The Cracker: After Schwartz has him arrested, Tao takes revenge by hacking his company files to expose all of the latter's illegal dealings and have him imprisoned.
- Improbable Age: Tao's expertise covers multiple fields and he has yielded success in the sciences, technology and music. As the last episode reveals, he's only 25.
- Long-Lost Relative: In a convoluted way; Tao and Angela are Professor Zeeman's test tube-grown Designer Babies. They're (probably) not biologically siblings, but were created by the same man.
- Not Good with People: Tao prefers the company of his A.I. than other people, as Angela notes with annoyance at his indifference.
- OOC Is Serious Business: Both Angela and Dahlia are very surprised when he suggests Angela switches songs right before performing at Mars' Brightest based on a Gut Feeling.
- Rei Ayanami Expy: He doesn't look like one, but his icy personality and status as a genetically-altered designer baby fit the Rei Ayanami persona to a T.
- Renaissance Man: Tao is an expert programmer, researcher in the field of neuroscience and renowned music producer.
- The Social Expert: While claiming to dislike having to interact with people, Tao is quite adept at reading them and their reactions, at one point correctly predicting which kind of song will win Angela the round in Mars Brightest and at another assessing the behavior of her stalker to intercept and incapacitate him.
- Stoic Spectacles: Wears glasses and is a generally cold and inexpressive person.

Tuesday's older brother. He helps his mother out with her presidential campaign.
- Alliterative Name: Spencer Simmons.
- Cool Big Bro: Not only does he try to comfort Tuesday after she's brought back home, he even holds off the security robots so Tuesday can escape.
- Establishing Character Moment: When he sees his sister for the first time on stage, he immediately drops any plans to retrieve her.
- Honest Advisor: Unlike the slimy Jerry, he tries to advise his mother the best way he can, trying to convince her the ideas Jerry proposes will only bring disaster to her and the people of Mars.
- The Dutiful Son: Is willing to follow his mother Valerie's demands, whether it be things with her campaign or tracking down his little sister Tuesday. He will draw the line when he thinks it's appropriate, such as leaving Tuesday alone after seeing how much she is enjoying singing and helping her escape their home after she's forcefully taken back.
- Not So Different: He admits to his younger sister that, when he was younger, he also wanted to be a musician but gave up.
- Sugar-and-Ice Personality: Spencer doesn't emote very often, but he's a caring brother to Tuesday, and he worries what Valerie's anti-immigration platform will do to both her and innocent people of Mars.

A presidential candidate for Mars, and also Spencer and Tuesday's mother.
- Even Evil Has Standards: Valerie is hardly a good person, that's for sure, but finding out Jerry was the one behind the weather plant bombing prompts her to fire him and withdraw her candidacy for president.
- Fantasy-Forbidding Mother: She doesn't approve of Tuesday's desire to be a musician. She initially tries to overlook her running away from home at first (since bring attention to it will make her look bad), but she later takes her back home by force while Mars' Brightest is still running. She gives up entirely when Tuesday successfully runs away again.
- It's All About Me: If it's to advance her political career, she will lock up her own daughter at home and advocate to revoke Earth and Mars' trade agreement, which will most certainly ruin relations between both planets.
- Trumplica: It's not very difficult to see the similarities between Valerie - a blonde-haired politician spouting anti-immigrant, isolationist rhetoric - and a certain US president. The signs held up by some of her supporters in episode 15 look very similar to some Trump lawn signs-red, with the name of the candidate in the middle surrounded by a thin white rectangle with stars at the top and bottom.
- Toxic Friend Influence: In her desire to ensure her triumph as presidential candidate, she agrees to advocate her advisor Jerry's self-destructive policies that are certain to cause conflict between Earth and Mars.

- Beleaguered Assistant: She realises in the matter of minutes that working for Angela won't be a dream come true.
- The Bus Came Back: Katy gets cruelly fired by Angela half-way through the series after the latter accuses her of harming Tuesday. Katy later returns to the series near the end to start supporting Angela after she had a drug overdose due to Dahlia's death.
- Early-Bird Cameo: Look closely in Episode 1 and you can see her in the crowd watching Angela arrive. She makers her proper debut a couple episodes later.
- Meganekko: Wears glasses and is relatively soft spoken.
- No Good Deed Goes Unpunished: On Tao's instruction, Katy decides to scout out Carole and Tuesday's dressing room in order to get information for Angela. Unfortuantely, Cybelle's dry ice stunt that ends up injuring Tuesday not long afterwards and Katy vaguely matching the description of the culprit leads to her getting suspected by Angela and fired.
- The Scapegoat: With only Roddy's vague description of the perpetrator to go on, Angela assumes Katy is behind Tuesday's injury and shows her the door.
- Warts and All: Katy is Angela's number one fan, even in spite of all of Angela's negative qualities. Even after getting fired by her after a false accusation, Katy still returns to support her during her darkest hour following Dahlia's death.

An... odd old man, who turns out to be the famous music producer Tobe. He helps Carole and Tuesday out per Gus' request, albeit via Training from Hell.
- Birds of a Feather: Starts to get along with Gus very quickly because both are alcoholic, Texas-born old-school musicians.
- Bunny-Ears Lawyer: He's foul-mouthed, alcoholic, reclusive, and he first appears waving an axe around while babbling incoherently... but he's an excellent producer, and has the respect of everyone in the industry who knows him.
- Defrosting Ice King: While still brash, he confesses towards the end of production that he believed the girls were the real deal from day one and even joins up to play the organ for their song with Crystal. He's also proud when the two propose to organize an illegal concert to protest the crackdown on artists.
- Grumpy Old Man: Cranky and foul-mouthed, but considered a legendary old-school producer.
- Nice Hat: Fittingly for a Texas native, he owns a cowboy's hat.
- Shout-Out: A brilliant music producer who is mentally unstable, insists on perfection and threatens artists with weapons? Why hello there, Phil Spector!
- Sink-or-Swim Mentor: He is incredibly demanding of Carole and Tuesday, requiring dozens upon dozens of takes and rejecting about a hundred of song proposals of theirs after hearing half a note. He's like that because
- Sir Swears-a-Lot: Says the word "shit" quite a lot, for both insults and compliments.

- Perma-Stubble: Has the unshaven style, and it goes with his laid-back approach to stories.

An IT guy who helps out Angela set up security for her house amongst other things.
- Professional Butt-Kisser: Tao describes Aaron to be someone who likes to kiss up to his clients in order to get stuff in return, which is why he tries to cozy up to Angela.
- Red Herring: Despite suspicions, he's not Angela's net stalker Black_Knight. In fact, he's attacked by the real stalker.
- Replacement Goldfish: Hired to replace Katy. Subverted when he is injured in a car crash and quits, and by Episode 23, Katy has apparently been hired back.
- Saying Too Much: While trying to assure Angela, Aaron says he wants to be her "knight", which Angela notices is similar to the creepy messages she's been getting on social media.
- Screw This, I'm Outta Here!: After nearly getting killed by Black_Knight, Aaron decides he wants nothing more to do with Angela.

DJ Johnny Ertegun
Voiced by: Mamoru Miyano (JP), Ray Chase (EN), Ricardo Méndez (MEX)
A famous DJ who Roddy works for. He later guest stars on Mars' Brightest to judge, which is unfortunate for Carole and Tuesday due to the... rough first meeting they have with him beforehand.
- Break the Haughty: Has a crisis and becomes self-deprecating, thinking he is washed up, after his AI manager steals his identity and causes him to go bankrupt. He turns back around to his usual self quickly.
- Catchphrase: Prone to saying "Fire!" during his performances, and a rhetorical "Who am I?" when he goes into speeches about himself.
- Dumbass DJ: A DJ who is also a self-absorbed jerk.
- Good Angel, Bad Angel: Has a variation of the angel/devil imagery after his bankruptcy. Ertegun hallucinates a version of himself that mocks him, calling him a washout and saying that everyone is laughing at him, and another version of himself that encourages him and tells him he's an awesome DJ.
- Hidden Depths: He initially plans to make his speech when announcing the Best New Artist Grammy about himself. He ends up criticizing the government for rounding up artists and interfering with freedom of speech. He subsequently doesn't need much convincing to get in on Carole and Tuesday's illegal concert.
- It's All About Me: He's so self-absorbed, anything not related to him or his career may as well not be worth dirt. What makes this so delusional is that he doesn't even write his songs. They're all written by A.I. algorithms.
- Odd Friendship: "Friends" might be a stretch, but he gets along with the rather shy and unassuming Roddy.
- Performance Anxiety: Subverted at the fall Cydonia Festival, his first concert after the aforementioned Break the Haughty moment. He immediately curls up beneath the spotlight, whining that his fans will have forgotten him, and Carole and Tuesday think he's relapsed... but it's just a ploy to goad the audience into calling his name, and he rises to his feet in a matter of seconds to tremendous cheers.
- Pet the Dog: He tears up and genuinely praises Carole and Tuesday after their performance at Mars' Brightest finals. Even before that, he doesn't press charges when they set off the fire sprinklers and alarm with a fiery prank. He also calls Tao a friend who helped him during a rough time at the Grammy's, appalled that he was arrested.

- Bare Your Midriff: Her performing clothes show her midsection.

- Nice Girl: She congratulates Carole and Tuesday for their efforts at Cydonia's festival despite being booed by the crowd, and even hugs them to motivate them.

- The One That Got Away: Their interactions imply Crystal is the subject of Skip's song, "Unrequited Love".
- Rapunzel Hair: Crystal's hair goes past her waist.

A musician Carole and Tuesday meet at the Cydonia Festival.

- Gentle Giant: Skip may be introduced as a Scary Black Man, but he genuinely compliments Carole and Tuesday for writing their own songs and willingly helps provide them backup when recording their music.
- Singing Voice Dissonance: His speaking voice is deep and intimidating, but his singing voice is much higher and soft.

Voiced by: Kōichi Yamadera (JP), Marker Starling (Singing), Patrick Seitz (EN)
A legendary musician who stopped appearing in public at one point.
- Ambiguous Gender: Similarly to Dahlia, Mars' radiation has altered their hormones, meaning that while they were born male, they now feel like something in-between.
- Disney Death: Appears to pass away peacefully after their final song in their feature episode. They are later shown to be in a coma on life support, but they open their eyes in Episode 23. They finally leave their mansion and sings along with everyone else in Episode 24.
- Facial Markings: Desmond has a purple triangular marking just under their mouth.
- Finger-Twitching Revival: In Episode 23, their finger is seen twitching. This reveals that not only are they comatose and Not Quite Dead, but they're about to wake up from said coma. Sure enough, they join Carole and Tuesday for their big performance in the finale.
- The Lost Lenore: The only man they ever loved passed away years ago, leaving them with only his songs as comfort.
- No Celebrities Were Harmed: Desmond's glam rock-inspired singing calls to mind David Bowie and they look like one of the singer's personas such as Ziggy Stardust.
- Reclusive Artist: An In-Universe example; they've spent 20 years without making public appearances, with only their plants and A.I. butler as company, although they have occasionally invited rising artists to their home.

A former singing star who was discovered by Gus before signing a contract with a big label and cutting ties with him. Gus, Carole and Tuesday find her 20 years later, homeless and broken.
- Broken Bird: After years in the music industry without anyone to really trust, she sank in a depression and lost the will to sing.
- Dark-Skinned Redhead: Has tanned skin and red hair.
- I Was Quite the Looker: Downplayed; Flora's not completely without her good looks, but years of depression and substance abuse have done a number on them.
- My Greatest Failure: Firing Gus as her manager resulted in her left without anyone to trust in the music industry, something she deeply regrets. Gus, for his part, feels that letting her go so easily was his greatest failure.
- No Celebrities Were Harmed: Flora's backstory, music, and appearance is based off of Whitney Houston who also had a history of drug addiction that eventually lead to her death. Flora's story, thankfully, ends on a much brighter note.
- The One That Got Away: Clearly she and Gus felt something for each other, but she chose to cut ties with him to continue her career. She comes to regret it in the present.
- A Tragedy of Impulsiveness: Flora grew up poor, so she dropped Gus in favour of professional managers as a quicker path to stardom and wealth when her chance came. If she had stuck it out with Gus, Flora probably could have had a happier and fuller career.

Famous rapper and childhood friend of Carole, back when they lived on Earth.
- An Immigrant's Tale: Like Carole, he lived on Earth before emigrating to Mars. But he had a much harder time than her surviving as an illegal immigrant.
- Break His Heart to Save Him: He tells Carole to stay away from him so she won't risk getting condemned by association for his anti-government music.
- Childhood Friends: Has known Carole since they were small, but ten years of separation have made him distant towards her. The song he writes for her while he's in jail implies he may have had feelings for her.
- Masculine Girl, Feminine Boy: According to Carole, he was the sensitive one while she protected him. Not so much the case in the present, where he has more of a gangster attitude.
- Political Rap: His style of predilection, which doesn't bode well during a presidential campaign where anti-immigrant sentiment is surging.
- You Gotta Have Blue Hair: Has bright purple dreadlocks, though, flashbacks to his childhood make it obvious they're dyed.

- Freudian Trio: The ego among the judges. Benito is more emotional and the other two are more clinical or detached, while she acts as the center of the group.
- You Gotta Have Blue Hair: Has lilac hair.

A judge for Mars' Brightest.
Voiced by: Hiroyuki Yoshino (JP), David Vincent (EN)
An A.I and judge of Mars' Brightest.
- Freudian Trio: The superego among the judges. As one would expect from a robot, he makes it clear that he doesn't have the same feelings as others. All of his judgments come from logical conclusions based on his programming.
- Ridiculously Human Robots: He's an A.I. using the body of a robot dog, but advanced enough to give judgement for the contest.
- Robot Dog: He's an A.I who takes the form of a small robotic dog.
- Running Gag: Saying to the audience that, as an A.I., he doesn't entirely understand how humans feel.
Voiced by: Shouta Aoi (JP), J R. Price (singing), Erik Kimerer (EN), Marc Winslow (MEX)
A social media star and contestant for Mars' Brighest.
- Agent Peacock: He might exude Camp Gay stereotypes, but he's certainly a good singer and dancer.
- Ambiguously Gay: His backstory reads like a Coming-Out Story, and his song was basically a knock-off version of Lady Gaga's "Born this Way". Notably, the backstory resonated extremely well with Benito.
- The Bus Came Back: Roddy reveals in Episode 23 that Pyotr has formed a duo with GGK called Losers; the duo properly appear the next episode to help Carole and Tuesday with their project.
- Camp: The guy sure is campy, although his sexuality isn't confirmed.
- Catchphrase: He likes to say an enthusiastic "Pow!"
- Crouching Moron, Hidden Badass:
- Everything about his character development before he hits the stage sets him up to be a shallow, dumb, purely irritating character. Once he hits the stage, his skill is terrifying. Once he finally gets defeated (at the hands of Carole and Tuesday), he reminds everyone his whole goal was to boost his existing fan base, which he accomplished. Then he congratulates the winners and exits the stage like a total boss.
- Despite only taking part in the competition to gain more followers on social media, Pyotr ends up developing a real passion for music through the experience and ends up forming a musical duo with GGK afterwards.
- Graceful Loser: Pyotr has no hard feelings about his loss to Carole and Tuesday, telling them their music touched him as well. Besides, just appearing on the show got his channel tons of new followers, which is what he wanted most!
- Hidden Depths: He seems like a total clown and show-off, but he's very serious about his music. Also, he spent years stifling his true self to fit in. Only after being true to himself was he able to love himself.
- Nice Guy: He acts warmly with Carole and Tuesday before their match and assures them that the competition between them is friendly and fair. He's also a very good sport when they eventually beat him.
- Singing Voice Dissonance: On the opposite side of Skip. His speaking voice is high and girly, but his singing voice is deeper and more masculine.
- Xanatos Gambit: His goal the whole time is to boost his viewership. Win or lose, this boosts his numbers, so he benefits just by virtue of showing up and posting videos of his experiences.
- You Gotta Have Blue Hair: His hair is mint-green. The lowlights underneath imply his natural color is brown.

A contestant for Mars' Brightest who takes an immediate liking to Tuesday.
- Ambiguously Gay: Her sexuality is unknown, but her devotion to Tuesday implies she's at least attracted to women. She even gives her a playful bite on the neck.
- Bifauxnen: Has Boyish Short Hair, gender-neutral clothing, and speaks in a tomboyish voice. She also uses the masculine pronoun "boku".
- Entitled to Have You: She views Tuesday as hers, citing that she "claimed" Tuesday when she bit her neck.
- Everything Sounds Sexier in French: She chooses to sing in French because it's a "beautiful and elegant language", and she does with a very whispery and sensual voice.
- Expy: A creepy, wildly aggressive, manipulative fan girl with an unhealthy fixation on a female musician main character? Check. Their conflict takes place in a colorful world dominated by technology, where the AI is a crapshoot? Check. She's Sybil from Transistor. Their names even sound the same!
- Fangirl: A big fan of Tuesday, though apparently not Carole.
- Hoist by Their Own Petard: Cybelle's If I Can't Have You... stunt in which she seriously burns Tuesday's hand not only gets her arrested, but leads her to destroying any potential friendship she could have had with her. Particularly notable at the end of the series where Carole and Tuesday end up collaborating with majority of the artists they've met.
- If I Can't Have You...: After Tuesday turns down Cybelle's offer to become a duo, Cybelle decides to try and sabotage her and Carole's performance on Mars' Brightest by burning Tuesday's hand with dry ice.
- No Sense of Personal Space: She greets Tuesday in a way too casual manner when first meeting her. She even hugs her without waiting for her response, and even goes to ask for a kiss before Carole interrupts.
- Sanity Slippage: Cybelle was already a bit unhinged due to uncomfortable hero worship of Tuesday, but then she ends up completely losing it when Tuesday turns down her offer of becoming a duo act with her, viewing the snub as a betrayal.
- Stalker with a Crush: She's apparently a big fan of Tuesday, and assumes they have some kind of bond even before meeting. When Tuesday summons the spine to tell her she's not interested in forming a duo with her, Cybelle gets angry and displays a frighteningly possessive side.
- Surprisingly Good Foreign Language: Her song in French is pretty good despite it (presumably) not being her first language in-series. The real-life singer behind Cybelle, Maika Loubté, is half-French.
- Yandere: Displays frighteningly possessive behaviour towards Tuesday. For Tuesday's "betrayal" of going back on her promise that they'll form a band together (something that didn't happen to begin with), Cybelle sets up Tuesday to burn her hand on dry ice.

99-year-old twins and the oldest contestants in the history of Mars' Brightest.
- Cool Old Guy: How often do you see ninety-year-olds playing the electric guitar and singing rock?
- Feeling Their Age: Being as old as they are, they're both very hard of hearing and they're clearly exhausted after their performance.
- Only Known by Their Nickname: Their actual names are never mentioned.

A contestant for Mars' Brightest, and Carole and Tuesday's first opponent.
- Face of a Thug: He looks like a gangster, as one would expect. But as his grandmother tells us, he's actually very timid and would never commit a crime.
- Hidden Depths: Despite his thug appearance and brash behaviour, his song is a combination of rap with classical opera.
- Hoist by His Own Petard: It's implied that had Bulldog been honest about his background, he might have actually made it to the next round instead of Carole and Tuesday. His lie getting exposed only caused further suspicion of how much his music was legitimate.
- Paper Tiger: He might look threatening, but in reality he's a huge softie who loves his grandma.
- Starter Villain: While not really a villain, he's the first person Carole and Tuesday have to directly compete with.

A group of siblings and contestants of Mars' Brightest.
- Ambiguous Gender Identity: Three out of four of them wear frilly dresses and they claim to be part of a new race that transcends gender, but it isn't made clear what any of them actually identify as.
- Berserk Button: They attack the show judges for "disrespecting" (read: not liking) their lyrics.
- Lyrical Dissonance: The lyrics of their song is nothing more than a long string of curses, which doesn't go at all with the peppy rhythm. This is the reason Catherine kicks them out before they could even finish.
- Only Known by Their Nickname: Their actual names are never mentioned.
- Same-Sex Triplets: They seem to be quadruplets, but only one of them isn't dressed as a woman.

A whimsical contestant on Mars' Brightest.
- Ambiguously Brown: She is black but she has unknown ethnicity. The bindi suggests Indian descent.
- Bunny-Ears Lawyer: As weird as she is, her singing is actually quite good.
- The Bus Came Back: Episode 23 reveals GGK formed a duo called Losers with Pyotr; the two properly reappear the next episode to help Carole and Tuesday with their project.
- Cloud Cuckoolander: The woman is rather weird, believing she's connected to the universe, hence why she lists her age as the age of the universe and 22.
- Graceful Loser: She clearly has no hard feelings after losing to Angela.
- Hidden Depths: We learn from her backstory that she was stifled and felt dead in her old life. She came to the city to find a place where she belonged, and found her calling through music. Her whole "at one with the universe" schtick seems to an expression of how she feels now that she's truly living and happy.
- Loon with a Heart of Gold: Unbelievably off her rocker, but she seems to be a friendly person besides.
- Vocal Dissonance: Her soft, childlike speaking voice doesn't match her angular features at all.
