Miss Heinous' subalterns
See his folder here.
Miss Heinous' faithful manservant.
- Affably Evil: Always polite, smiling and ready to serve.
- Alas, Poor Villain: It's hard not to pity Gemini, since he was a subordinate who dutifully stuck by Heinous even after she lost everything, out of a sense of loyalty and love to her. She repays this loyalty by killing him, ripping out his heart to use to kill Rasticore for trying to walk out on her. Even then he takes her betrayal with no ill-will.Gemini: If you wanted my heart, all you had to do was ask...
- And Show It to You: A crazed Meteora rips his Heart Drive out and uses it to blow up Rasticore.
- Anti-Villain: He isn't all that villainous, and even has a secret adoration of "Princess Marco", even considering him a Worthy Opponent.
- The Dragon: He's Miss Heinous' lieutenant and enforcer in St. Olga's.
- Ignored Enamored Underling: In "Skooled!" it's made abundantly clear that he serves Miss Heinous out of love, yet she treats him with nothing but contempt. After Rasticore rejects her, Gemini offers her his own continued service, only for Heinous to rip out his heart and use it to blow up Rasticore.
- Killed Off for Real: He's killed in "Skooled" when Heinous rips out his robotic heart. He is not seen again since, though it's unknown if it's because the heart couldn't be replaced or if there was simply no one to replace it for him.
- No Respect Guy: Miss Heinous has no respect for the man no matter how much he does for her, and even makes him sleep in the trunk of her car. She even kills him in a fit of rage when he remains nothing but loyal to her.
- Only Sane Man: He clearly recognizes that Princess Marco's apology is intentionally backhanded and sarcastic, but Miss Heinous doesn't notice.
- Punch-Clock Villain: He's not a malicious individual, he's just working for Heinous, (he is a robot after all) whom he's implied to have feelings for.
- Punny Name: In his case, Gemini means "Gem in Eye".
- Robotic Reveal: He's revealed to be another robot when Miss Heinous rips open his chest plate and uses his heart to blow up Rasticore.
- Subordinate Excuse: Seems to serve Heinous because he has feelings for her.
- Undying Loyalty: To Miss Heinous. He offers himself to Heinous after she drained Smooshy of her powers to the point of unconsciousness. He remains loyal to her after she has a mental breakdown upon the discovery of her true identity.
- Doom Troops: The guards of St. Olga's are designed with maximum intimidation; deathly cold voices, show no mercy, masked faces, and the like. Seriously, they look like they stepped out of BioShock.
- Determinator: If a student escapes, they are very persistent and will stop at nothing to find them and capture them.
- Elite Mooks: Compared to Ludo's mooks, these guys are tough and scarily competent that fighting them is not recommended. Your only choices are to Run or Die.
- Evil Sounds Deep: These droids have deathly cold voices.
- HeelFace Brainwashing: By the time of "Skooled", they are shown to have been reprogrammed by the princesses after taking over St. Olga's.
- Knight of Cerebus: When they appear, there is absolutely nothing funny about them, spending their appearances bullying innocent bystanders, or casually abusing their power on the other princesses.
- Mecha-Mooks: They are robots that are quite numerous, aggressive, and have glowing eyes that spell death. Their "hearts" are actually their power cores.
- Suicide Attack: Instead of sacrificing themselves as is the usual case with this trope, their attack involves sacrificing what keeps them alive. They have a protocol that allows them to remove their power cores and use them as grenades in a desperate maneuver.
A robot tasked by Shastacan to raise Meteora. St. Olga's school is named after her.
- Ambiguously Evil: At the end of the day she was just doing her job. Still, it's ambiguous whereas she cared about Meteora or not; she was abusive to her (under orders), but she did think her "name" was pretty.
- Abusive Mom: Suppressed Meteora brutally, emotionally and verbally tormented her if she did anything wrong, and instilled some severe self-image issues. It was so bad that Meteora ended up relying on her parenting methods just to give herself some sense of normalcy. And when Meteora got her memories back and stood up to her years later, her response was to emotionally manipulate her again and guilt-trip her into being "thankful".
- Back for the Dead: St. Olga is reactivated after rusting for decades in the school. We get to see a bit of her backstory and how she raised Meteora... and then she destroys Olga after getting what she wanted.
- Foil: To Eclipsa. Both were mother figures to Meteora Butterfly. Eclipsa was Meteora's biological mother who was a genuinely caring parent who adored her daughter's monster features but was forcibly separated from her child, Saint Olga was Meteora's adoptive, abusive mother who emotionally manipulated Meteora to hide her monstrous nature and "raised" Meteora all of her life. Also, while Meteora loved Eclipsa and never hurt her, she killed Saint Olga when the android made one too many inappropriate comments.
- Karmic Death: Was eventually destroyed for good by the very person she raised and abused.
- Knight of Cerebus: Her appearance on-screen was when things started taking a very dark and tragic turn in Season 3.
- Literal-Minded: When Shastacan describes Meteora as "heinous", she thinks that's her actual name, and that's a pretty one at that.
- Machine Monotone: Her words sound like they were spoken separately and strung together into sentences, giving her a stilted mechanical voice.
- The Perfectionist: Meteora, as Miss Heinous, took it from her.
- Predecessor Villain: Considering that she was the original headmistress of St. Olga Reform School and that "Miss Heinous" was just a persona instilled into Meteora by her abusive parenting, St. Olga automatically becomes this to any episode that features the horrors of either Miss Heinous or the school itself (which Heinous controlled). A bit of a strange case as she's not an actual antagonist and just Ambiguously Evil.
- Prim and Proper Bun: Her robotic design has a bun, fitting her personality.
- Shadow Archetype: To Queen Butterfly. While Moon can be overbearing and very critical of her daughter's flaws, she does it because she wants her daughter to be prepared to take over as queen. With St. Olga, her constant verbal and emotional abuse of Meteora left her daughter with severe identity issues and stunted her development such that grew into a Womanchild with the inability to give or even comprehend love.
- Too Dumb to Live: You would think that being shut down and left to rust would leave someone wary of pissing off the one responsible. Instead St. Olga goes right back to her emotionally abusive and manipulative ways, a mistake that gets her scrapped for good.
- Walking Spoiler: It's impossible to talk about her role in the story without first revealing who Miss Heinous truly is.
Princess Patty Arms
A princess from an unnamed kingdom. She's a student of St. Olga's, taking control of the school after Heinous is kicked out and Pony Head abandons her initial leadership role in favor of partying.
- Action Girl: "Skooled" shows that she's not afraid of getting her (four) hands dirty, as she defends St. Olga's against Meteora from the frontlines.
- Authority Equals Asskicking: Being the leader of St. Olga's rebel princesses, she is the one who puts the best resistance against Meteora during her attack in "Skooled", confronting her in at least three different stances.
- Gag Nose: She has a long, pointy one.
- Hairy Girl: As shown in "Skooled", four arms mean four hairy armpits that she has to shave every now and then.
- Multi-Armed and Dangerous: Well, not exactly dangerous, but she does take a leadership role once Miss Heinous is ousted as the St. Olga's principal, so she definitely holds some respect among the other princesses there.
- In "Skooled", she is shown to be capable of punching down one of St. Olga's robot guards, which is quite the feat as those things have already show how tough they can be in previous episodes.
An ugly goblin-elephant princess that was on the run from St. Olga's. She tried to switch faces with Star so she would go instead of her.
- All There in the Manual: Her name isn't mentioned in the show.
- Calling Your Attacks: She narrates the actions she performs, such as "Camera Phone," "Nose Grab," and "Laser Finger."
- Catchphrase: "Camera phone." which she says whenever she takes a selfie.
- Face Stealer: She wanted to switch faces with Star's as part of a Zany Scheme to escape St. Olga's.
- Frickin' Laser Beams: She can fire a laser beam from her finger.
- HeelFace Turn: In her third appearance, she is no longer hostile to Star and Marco, and is a whole-hearted supporter for "Princess Turdina".
- Selective Obliviousness: She seems to be under the very wrong impression that she and Star are physically identical, save for their faces.
- Uncertain Doom: In "Princess Turdina" she's last seen being drained of magic by Heinous and presumably falls unconscious after Gemini releases her. She hasn't been seen since then. It is implied that Eclipsa's Depower spell returned her energy to her, as it did with all of Miss Heinous/Meteora's victims. However, she may have been abandoned in that dimension with no means of escape or survival.
