Debuting in episode 39 the first series as a baby Jewelpet born through Raku Majo's magic, she's a genius child who has the Super Crystal Class ranking, which means that her magic is always powerful and successful.
In Twinkle, Labra is introduced in episode 3 spying on the classes of the Magic Academy and pranking its students. She wishes for her own human partner, but everybody she asked turned her down. She's incapable of using magic, although she releases a great deal of power when placed under stress. Because of this, Nicola accuses her of not being a Jewelpet, which drives her over the edge and makes her break Moldavite's statue. Akari then requests to be her partner and fixes the statue with her help, awakening Labra's dormant powers in the process. Labra is capable of amplifying the power of the spells cast by Ruby and Akari. She doesn't stay as often as Ruby (who acts like her big sister) in the human world.
In Sunshine, she is part of the Plum class and shares a room with Angela. She is gifted with immense power, but has too little common sense to use it wisely. She has visions of Jewelina more frequently than any other Jewelpet.
In Kira Deco, she, alongside Angela, is a patrol officer of Jewel Town. Despite her cute looks, she is a licensed police officer who can sentence anyone to jail for more than 600 years. She accepts high amounts of Deco as bail, which is how Pink and Blue escape imprisonment in jail.
In Happiness, she is one of Ruby's friends who is given a mission to make friends and run the Jewel Cafe. She works as a waitress. She has a bit of a rivalry with Rosa.
- Amplifier Jewelpet: Twinkle, where her power is to optimize the pre-existing magical capacity of her partner(s).
- Baby Talk: Since Twinkle. She couldn't talk at all in the first series.
- Bears Are Bad News: If she gets angry or upset, she will bust out her reality-warping magic, or cry supersonically at best.
- Beary Friendly: She's adorable and cuddly in a good mood.
- Berserk Button: In Twinkle, she's not very amused by people who think she's a dog.
- In Sunshine, say that she's too young to do something and magic will hit the fan.
- Betty and Veronica: A friendship variant in Happiness. She's the Veronica to Rosa's Betty.
- Breakout Character: While she is introduced late in the first series, she doesn't come into her own as a major character until Twinkle.
- The Chick
- Children Are Innocent / Kids Are Cruel: Presents both tropes, though in the first two seasons she only shows the first one. Starting with Sunshine, she becomes more driven by her own desires, which is reflected in her selfish treatment of the people around her, but most of the time she doesn't really know that she's hurting people with the things she does, just like a real baby.
- Child Mage: She's a baby, the youngest of the Jewelpets, but she has larger magical potential than any other and sometimes demonstrates reality-warping abilities that few other pets have.
- The Chosen One: One of the Wise Ones (seven people fated to save Jewel Land in its darkest hour) in Sunshine.
- Cool Crown: Wields one in the movie's climax.
- Demoted to Extra: She has consistently been a major character since breaking out in Twinkle, but is reduced to appearing in only one episode of Lady as little more than the object of an exam. Her major character status is restored in MC though.
- Friend on the Force: She's a cop in Kira Deco, and becomes an ally of the Kira Deco 5 after misundertandings are cleared up.
- Get a Hold of Yourself, Man!: In a late episode of Sunshine, she hits Angela in the face with a blowdryer when she's doubting her partnership with Shouko.
- Goo Goo Godlike: She's the youngest Jewelpet and the most powerful. She even represents Hidden Powers for Jewelina's sake.
- Great Gazoo: Possesses cosmic-grade powers and loves using them to play around.
- Heart Symbol: On her ears and hindpaws.
- Improbable Age: Sunshine; she's a toddler but is already in the last year of high school? Whoa.
- Innocent Blue Eyes: Her eyes have a blue edge to them, as in "baby blues".
- Innocently Insensitive: Much like an actual child she can say some awful, self-centered things.
- It Amused Me: She'd rather use magic to amuse herself than to do good (or bad) by others.
- Jerk with a Heart of Gold: She becomes brattier as the anime goes on, but is still firmly on the good guys' side.
- Kawaiiko: She rivals Ruby at this.
- Kid-Appeal Character: Tiny, fluffy, childlike.
- Killer Rabbit: While she is a baby and adorable, she has hardcore magical power that usually manifests in her cries (supersonic and potentially catastrophic). Jewelina says in Sunshine that her power is that of the universe, so yeah.
- Make Me Wanna Shout: Her famous screams are implied to be powered by her immense magic, and not rarely have scared enemies away.
- Meddlesome Patrolman: Kira Deco.
- Overranked Magician: She becomes an improbably high-ranked magician at Jewelina's direct service in the epilogue of Sunshine, despite still acting like a baby.
- Reality Warper: Her magic allows her to change the laws of physics as she pleases. Shown in Sunshine when she manages to turn precisely an entire classroom upside down and shift gravity upwards.
- Robe and Wizard Hat: Epilogue of Sunshine. It's a symbol of her mastery of magic. See here◊.
- Her Puroland version, also seen in episode 27 of Twinkle and episode 40 of Kira Deco.
- Star Power: Her power is that of the universe, after all. When she casts a spell, the incantation scene will usually show planets, stars and the like around her. She also has her Saturn necklace to drive the point further home.
- Tag Along Kid: Usually forms a team with Ruby, Garnet, Sapphie and Angela (add Rosa or replace everyone but Ruby with Luna and Larimar depending on the season). Despite her power, since she's a brat she hinders more often than helps though.
- Those Two Girls: Constantly seen with Angela as of Sunshine. Turns into a Power Trio with the addition of Rosa in Happiness.
- Took a Level in Jerkass: Becomes meaner with each passing season.
- Un-Sorcerer: At her introduction in Twinkle, she's incapable of casting magic, which isn't normal for a Jewelpet. It turns out that she can only unlock her powers by becoming someone's partner, and that her power of spell amplification is one that no other Jewelpet has.
- Verbal Tic: Labu~. Translated in some dubs as Gugu~.
- Vitriolic Best Buds: With Rosa.

In the first series, he's awakened by Hattori in episode 7, when Diana's curse causes him to fall ill. Because of his Acrylic Class rank, his healing power is very painful to those who go through it, but Hattori is strong enough to manage. Later, he reveals that he's in search of Lapis, who he's in love with. When it turns out she's under Dian's possession, he half-heartedly joins him to be with her.
In an episode of Twinkle, Ruby dresses up as King to pass for male and to try to become Nicola's partner. King himself appeared on episode 43 as one of the judges of the Jewel Star Grand Prix.
In Sunshine, he's a small-time villain of sorts and appears alongside Brownie and Alex, who function as his lackeys.
In Kira Deco, he is a Con Man selling items made of jewels which he claims to have magical properties. Seeing Pink and Ruby feuding, he convinces Ruby to give him the Deco Stones in exchange for his items. Though at first he cares little for Ruby and Pink's relationship, Ruby's determination ends up touching his heart and he gives her some advice (masked as a 'jewel of courage') for free. However that doesn't stop him from getting arrested and giving back the Deco Stones.
In Happiness, he is the new, popular student at Jewel Academy. He becomes Red Mooned over his demeaning thoughts about Machiko's isolation and becomes a delinquent. Machiko believes he's still good at heart and draws a manga to prove it. It touches King's heart and he recovers, forming a Magic Gem.
In Magical Change, he serves as Sumire's pet dog, under the name "Monohime". He is the least popular Jewelpet in Jewel Land and his magic isn't very good. He is also one of the Jewelpets to achieve their human form.
- Because You Were Nice to Me: King becomes lonely Sumire's pet dog in MC because she was kind to him when everyone back home in Jewel Land treated him poorly.
- Butt-Monkey: King is considered in-universe the most unpopular of all Jewelpets and tends to be treated accordingly by the plot, if not the characters.
- Canine Companion: In MC, he passes himself for a regular (non-magical, non-speaking) dog owned by Sumire.
- Coat Cape: King's very manly human form wears a pink coat with the arms free from the sleeves.
- Combat Commentator: His role in Twinkle is to offer commentary on the Jewel Star Grand Prix and be an arbiter of it.
- Cool Crown
- Corrupt Corporate Executive: He owns a fruit-selling company called Donbikiya in Sunshine and is a money-grubber who's completely ruthless towards his clients.
- Dark Is Evil: Sunshine. Forced to in the first series.
- Dark Is Not Evil: Twinkle. Is in some sort of grey area in Kira Deco.
- Dogged Nice Guy: First series, to Lapis. He's very nice to her and is determined to bring her back, even when she treats him like crap.
- Era-Specific Personality: An ally in the first series, a Large Ham in Twinkle, a jerkass in Sunshine and a travelling Con Man in Kira Deco.
- Female Feline, Male Mutt: With Lapis in the first series.
- Forced into Evil: First series, for Lapis' sake, in episode 36. Gets better in episode 46.
- Gender-Blender Name: Sumire from MC calls him Momohime (Princess Peach) after a dog she used to have. It's all the funnier that she keeps calling him that in his human form.
- Healing Magic Is the Hardest: First series. He's the only known Jewelpet capable of performing healing magic. Thanks to his Acrylic rank, it's not only extremely improbable that it'll work at all, but when it actually works, the healee is forced to go through unimaginable pain.
- Heroic Sacrifice: First series. When Rinko's team loses the Jewel Game of episode 35, he lets himself get captured instead of her.
- Idiot Ball
- Interspecies Romance: First series. King's love interest is Lapis and he will do anything to get her back from Dian's clutches, to the point of being captured twice.
- Machiko is implied to be crushing on him in episode 43 of Happiness.
- Iron Butt Monkey: First series.
- Japanese Delinquents: The Red Moon turns him into an over-the-top one in episode 43 of Happiness.
- Jerkass: Sunshine, alongside Alex and Brownie.
- Jerk with a Heart of Gold: Kira Deco.
- Magic Feather: The 'jewel of courage' that he gives to Ruby in order to make peace with Pink. They mend their relationship because of their sincere apologies; the jewel was simply a placebo.
- The Medic: His role among the Jewelpets in the first series and meta, as the one who performs healing magic.
- The Millstone: In the first series, he's frequently why Dian's group loses the Jewel Games. Thing is, he's not even doing it on purpose.
- New Transfer Student: In Happiness. He transfers into Jewel Academy in episode 43 and is the focus of it.
- Odd Name Out: The one pet not named after its eyes.
- Rated M for Manly: His human form in MC is very big and rugged and not bishonen like the other male Jewelpets (he still keeps his pink colors but see below).
- Real Men Wear Pink: He IS pink, and his human form in Magical Change pegs him as one of the manlier Jewelpets.
- Sinister Shades: Sunshine.
- Snake Oil Salesman: Kira Deco. He sells such things as a tickler, a pepper flask and a mallet claiming that they have magical properties and will help mend the relationship of Pink and Ruby. All of them backfire spectacularly.
- Spanner in the Works: Helps Mikage figure out the Dark Queen's weakness by screwing with his singing to her.
- Take Me Instead: Intentionally gets himself captured by Dian to compensate for losing the Jewel Game and to spare Rinko.
- Taking the Bullet: His Heroic Sacrifice involves him diving in front of Dian's spell meant to capture Rinko.
- Token Good Teammate: Though forced to defect to Dian's side in the first series, he doesn't ever turn genuinely evil.
- Undying Loyalty / Conflicting Loyalty: First series. He is very loyal to Rinko and Lapis, so he often feels divided and hates the thought of betraying either of them. Even Diana brainwashing him worsens his conflict instead of tipping him to one side.
- Vocal Dissonance: His male-but-squeaky voice doesn't match his big, brawny, not pretty at all human self in MC.
- White Mage: First series, being a healing Jewelpet.

In the first series, she's the first real villain that Rinko has to contend with, as she's the one responsible for casting the curses starting in episode 4; through them, she hopes to awaken and capture Jewelpets. In episode 19, it is revealed that she was awakened during the events of episode 2 by taking in Rinko's magic. She is technically bonded to Sage, but treats the Phantom Herb Thieves as nothing more than disposable lackeys; they follow her anyways because of her promises of a better life for them. Later, it is revealed that her purpose is to awaken her brother Dian, which she achieves in episode 33. She gets relegated to second-in-command from there on. She hates any girl who becomes too close to Dian, and her jealousy often interferes in his plans.
In Twinkle, she is Alma's partner, and they are the main villains of the season. She is very playful and enjoys cruel pranks, while boasting about how powerful she and her partner are compared to everyone else.
In Sunshine, she is a student from the Rose class and Garnet's rival. She is the idol of her class and looks down on the Plum section like nobody else. She once dated Dian and managed to get back with him after much drama involving Garnet.
She primarily functions as a gag character in Kira Deco. She wears a bald wig, never speaks, and characters keep running into her in odd situations. Late in the season, she reveals herself to have watched over the KiraDeco 5's actions and decided to take them to Smooth Land to force the group to make her laugh.

- For the Evulz: In Twinkle, she says that magic should be used for fun. Cue humiliation of Akari and co..

Debuting in episode 33 of the first series, he's the main villain of the season. In ancient times, because he thought the humans were taking advantage of the Jewelpets' powers, he lead a rebellion against the Four Great Magicians, who put a stop to it and sealed him in an iceberg on Earth. After Diana unseals him, he decides to take revenge against those who did him wrong and to try and conquer both worlds. He corrupts eight powerful Jewelpets, the Jewel Eight, and challenges Rinko to the Jewel Games, betting the Jewelpets he corrupted against Rinko herself. He desires the Jewel Stick; however, only Rinko can make use of its power. When this doesn't go as planned, he resorts to turning into Rinko's dream Prince Charming in an attempt to seduce her.
In Twinkle, he's Leon's partner. They first met when Leon's dog died, and Dian told him to live with his head raised high and to not let its death go to waste. When the season starts, Dian's suffering from muteness, which is later explained to be caused by him having seen something he shouldn't have (specifically, Diana's creation by Alma). He gets healed after confronting what he saw again.
In Sunshine, he is in the Rose class and is a TV star. In episode 25, he noticed Garnet when she helped him mend his outfit for one of his gigs and they started dating. However, Diana, his former girlfriend, was still in love with him, and fought with Garnet over him. Garnet ended up giving up on him for Diana's sake, though he did inspire her to try harder to chase her dream of being a star. He appears a couple of times afterwards, with Diana.
In Kira Deco, Dian is part of Decoranian's Four Heavenly Kings, the highest ranking agents in the organization. He wreaks havoc in Jewel Town in episode 35, turning the denizens into cards. He nearly defeats Angela and Retsu in a card duel, only to commit the mistake of summoning Labra and Midori as his last cards, enraging Retsu and Angela, who disregard the game and attack Dian directly, breaking through his barrier and defeating him.
In Happiness, Dian is the host of a famous show about cooking vegetables, and works for Jewel Academy by providing the cafeteria with the best vegetables. The Red Moon influences him and he loses his sense of smell, which helped him with his job. With his gift gone, he falls into a depression. After the cooks discover that they committed a mistake in a dish which even Dian's numbed nose could detect, he regains his confindence and his sense of smell, and creates a Magic Gem with everyone present.

Coal debuts at the end of episode 2 of Kira Deco, working with the Decoranain, the group responsible for plunging the human world into darkness using Dark Magic, as an assassin. He is bossy, very boastful and impatient, though he tries to keep up a cool front around his allies Opal and Io. His goal is to find the Deco Stones and give them to his shrouded master while making sure the Kira Deco 5 are out of the way. He and his lackeys get beaten every episode.
In Happiness, he works various jobs in search of a Magic Gem. In episode 37, he loses all of them and becomes depressed. He finds a doll, possessed by the Red Moon, who pampers him with supportive words. He discovers that the doll belongs to a little girl named Yumika, but refuses to give her back. When the doll expresses that she misses Yumika very much, breaking away from the Red Moon, he yields and forms a Magic Gem with the girl, beginning the 3rd stage of the Jewel Box.

- Ambiguously Gay: As Coarumi, he doesn't do anything to stop Jewelpets from fawning over him and even seems to encourage them on some occasions (as when he went to buy lingerie with Io). That said, the whole thing could just be to make his guise more convincing, hence the ambiguity.

She debuts in Lady, where she's Lillian's partner and Ruby's rival.
In Magical Change, she's partnered with Laura Fukuouji.
- Alpha Bitch: In Lady, she loves to put down the other pets with the knowledge that her partner is the best-ranked Petit Lady.
- Anti-Villain: She's an antagonistic force in Lady, but isn't evil so much as extremely misguided. Despite plotting to expel Momona and being in cahoots with Joker, all she wants is to not be abandoned again and she genuinely cares about Lillian.
- Beauty Mark: The heart under her left eye.
- The Cracker: In Lady. She makes a habit of hacking into the school's computer system to check for things that can hinder or further her plans, and in the past inserted an illegal student, revealed to be Lillian, in the student body.
- Cynicism Catalyst: In Lady, Diana's bolting left her significantly less happy and trusting than before, not to mention it made her meaner to her rivals.
- Dark Is Not Evil: This black-themed Jewelpet can be a jerk and occasionally do some morally questionable things, but she's not really evil, just kind of a reckless woobie.
- Foil: She's a bunny Jewelpet like Ruby, and the partner to Ruby's partner's rival (Lillian and Laura are rivals to Momona and Airi respectively). While Ruby is Dumb Is Good incarnate and optimistic, Luea is more intelligent, more easily tempted by the dark side and more prone to obsess with bad things that have happened to her.
- Irony: She's the Jewelpet of Truth, but spends most of her debut season lying and concealing the truth.
- It Was a Gift: Her butterfly hairclip was a gift from Lillian in Lady.
- Jerk with a Heart of Gold: Like Diana with Alma, she's a Jewelpet who likes to put the others down but truly loves her partner (be it Lillian or Laura).

- Little Miss Snarker: Spends most of her screentime in Lady being sarcastic with Ruby and co..
- Lonely Doll Girl: She animated Diana's doll into Lillian to cope with her abandonment by the former.
- Never Be Hurt Again: She's possessive of Lillian because she doesn't want to be abandoned again like she was by Diana.
- Noblewoman's Laugh: Tends to let out haughty "oooh-ho-ho-ho" laughs. Not inappropriate considering her partners are a Proper Lady and a Rich Bitch.
- Please Don't Leave Me: In Lady, her flashbacks feature this phrase heavily. It is an indicator of her tragic past (Diana leaving her) and it underlines her resulting severe abandonment issues.
- Red Oni, Blue Oni: Blue to Ruby. She's cerebral and sophisticated.
- The Rival: To Ruby.
- Significant Birth Date: It's exactly 30 days/1 month after Ruby's.
- Tsurime Eyes: Luea has pointed eyes in her human form, suiting her arrogant character.
- Undying Loyalty: In Magical Change, because Laura took her in, Luea is completely devoted to her and does her best to help her get Sakutaro to be her big brother.
- Woobie, Destroyer of Worlds: In Lady, Diana's abandonment inspired her to join forces with Joker, become possessive and controlling of her next Petit Lady, and be ruthless to the competition.
