Royal family and associates

Royal Family, The House of Tarron

  • Blue Is Heroic: All Akiridions are blue, Krel is also this in his human form which sports a blue tee-shirt.
  • Brother–Sister Team: Aja and Krel are siblings, and are noted to work well together.
  • Foolish Sibling, Responsible Sibling: Aja had a habit of neglecting her royal duties, unwilling to face the responsibility, and was known to be quite rash. Krel, despite his fears of the same duties, would fulfill them when needed and is more level-headed than his sister.
  • Irony: When the series begins, Krel hates Earth and is eager to get back to Akiridion-5, while Aja is running away from responsibilities and eager to experiment life as a normal person. By the end of the series, Krel has decided to stay on Earth as he considers it his new home, while Aja goes back to Akiridion-5 to serve as queen.
  • Light 'em Up: This trope applies to the Akiridions in general. They are beings of light whose corporeal bodies are formed by their cores. And the bulk of their gear is based around hard-light constructs.
  • Nice, Mean, and In-Between: Aja is the Nice, Varvatos Vex is the Mean, and Krel is the In-Between.
  • Red Oni, Blue Oni: Aja is the more outgoing red oni and makes an effort to not just adapt but participate in life on Earth, while Krel is the blue oni who adapts only grudgingly, and prefers to spend time with his sister over Puny Earthlings.
  • Savvy Guy, Energetic Girl: Krel's the level-headed, somewhat grumpy Savvy Guy; Aja is the rash, excitable Energetic Girl.
  • Strong Girl, Smart Guy: Aja is a warrior-in-training, while Krel is a tech wiz-kid.

    Aja Tarron 

Princess Aja Tarron
Click here to see her true form. 
Voiced by: Tatiana Maslany

A teenage alien princess disguised as a human girl who appears in Season 3 of Trollhunters and is one of the main protagonists along with her brother in 3Below.

  • Action Girl: She's got some impressive combat skills, especially after being trained by Vex.
  • Big Sister Instinct: Aja is older than Krel and will kick anyone's ass if they threaten him in any way.
  • But Now I Must Go: She decides to return to Akiridion-5 as acting queen, as her parents died and her brother decided to stay on Earth.
  • Catch Phrase: "Lively".
  • Character Development: At the series' start, all Aja wanted to do was run away from any kind of responsibility and be normal. However, as she grows in skill, patience, and maturity throughout the series, she also comes to realize why her responsibilities matter. And at the series finale, she decides to leave Earth in order to rule Akiridion-5.
  • Character Witness: Aja saving Izita's daughter from falling rubble during the coup led the older woman to become a member of the rebellion to restore the Tarrons to the Akaradian Throne.
  • Contrasting Sequel Main Character: To Jim from Trollhunters. Jim is a responsible, only child, that always steps up to occasion, whereas Aja is much more rebellious and emotional than he ever was. Jim wanted something amazing to happen in his, but Aja just wanted to be normal.
  • Desperately Looking for a Purpose in Life: She feels unfulfilled as a princess and has spent most of her life trying to find something else. Eventually, she realizes that her calling is on the battlefield.
  • I Just Want to Be Normal: Aja wishes she could just be a normal person on her own planet and sees going to Earth as a chance to do that, but the fact she has to hide who she really is while fighting bounty hunters leaves her frustrated that no matter where she is she can't be normal.
  • Long-Distance Relationship: Having returned to her home planet, she and Steve decide to try a really long-distance relationship.
  • My Greatest Failure: She's wracked with guilt over delaying her parents' escape from Morando's attack, leading to them being forced into their cores.
  • Nature Lover: Unlike Vex and Krel, Aja loves the organic nature of everything she comes across. She especially loves trees.
  • Nice Girl: A sweet, friendly, good-natured girl who cares deeply about her planet and the people she loves.
  • Rebellious Princess: She spent her whole childhood trying to get out of being a princess, and was actually in the middle of her latest escape attempt when Morando's attack came.
  • Red Is Heroic: Aja is this in human form, which gives her a red button-up shirt.
  • Rightful Queen Returns: Once Morando is defeated, Aja accepts the Akiridion throne.
  • Strong Family Resemblance: Inverted. The fact that she doesn't resemble her brother at all is a clue that her human form is just a ruse. Played straight in their true forms, where they could easily be mistaken for Half-Identical Twins.
  • Unaffected by Spice: Being an alien allows her to eat the Diablo Maximus Breakfast Burrito without flinching, which astonishes Toby, who can eat it but had to build up a tolerance for spicy food to be able to enjoy it.
  • Uptown Girl: Being a princess, Aja counts as this for Steve.

    Krel Tarron 

Prince Krel Tarron
Click here to see his true form. 
Voiced by: Diego Luna

A teenage alien prince disguised as a human boy who appears in Season 3 of Trollhunters and is one of the main protagonists along with his sister in 3Below.

  • Alien Arts Are Appreciated: Subverted, much to his chagrin. He uses some remixed dolphin noises as music before realizing the humans don't get it and then dials it down to "easy listening", which translates to rave music in Earth terms.
  • Annoying Younger Sibling: Downplayed. He and Aja get along fine and are quite close, but he does have a tendency to annoy her.
  • Badass Bookworm: He's a Teen Genius, and can fight for his own self-worth, although he isn't as good as his sister, but makes up for it with his skills with tech.
  • Character Development: Krel starts off as being the most desperate between him and Aja to return home as he finds Earth to be nothing more than a "mudball". As he bonds with his human friends and grows to love music, he quickly grows an appreciation toward the planet, even dubbing it his home. He even decides to stay in the series finale.
  • Fantastic Racism: He doesn't think much of humanity at first, but gradually grows to respect it as the series goes on.
  • I Choose to Stay: Ultimately decides to stay on Earth, declaring it his new home.
  • Insufferable Genius: His haughtiness and impatience with Earth's lesser developed sciences don't endear him very much to his fellow students and the season ends with him having barely made any friends.
  • Jerk with a Heart of Gold: Krel is much more haughty than his sister and has much lower opinion of Earth, but he is capable of showing care for others, even those outside of his family.
  • Living Emotional Crutch: Aja is often overwhelmed by her emotions and needs the calm, balanced mind of her brother to help her.
  • Non-Action Guy: Played With, he's not useless in a fight, but compared to Vex and Aja, he's only just barely able to defend himself. Often while Aja and Vex are doing the fighting, Krel will be doing tech stuff, like disarming a self-destructing evil robot.
  • Playful Hacker: He uses alien tech to turn the Janus Order's secret hideout into a rave.
  • Puny Earthlings: Hardly an episode goes by where Krel doesn't degrade humanity or their technology. In season 2, he is shown to grudgingly accept Earth and show that his greatest fear is losing his new home to Morando.
  • Teen Genius: Even by the standards of his race, Krel is considered a technological genius with no equal.

    King Fialkov Tarron and Queen Coranda Tarron 

King Fialkov Tarron and Queen Coranda Tarron

Fialkov Voiced by: Andy García
Coranda Voiced by: Tatiana Maslany

The king and queen of Akiridion-5 and the parents of Aja and Krel Tarron. Following an attack on their home by General Val Morando, they are both injured and spend the majority of the series in regeneration pods to heal while their children work to protect them.

  • Action Dad /Action Mom: They are both skilled with serrators and use them with great skill.
  • Big Good: They are both this, being the beloved rulers of Akiridion-5.
  • Dissonant Serenity: Used to great dramatic effect. When their cores are finally revived, the first thing they do is calmly walk into a battlefield over to the cannon aimed at Morando, and power it with their cores.
  • Good Parents: Fialkov is this by supporting his son's interest in inventing while Cordana shows that she doesn't hold it against Aja for not wanting to become Queen in waiting
  • Heroic Sacrifice: In the final episode of the series, they use their cores to power the weapon to defeat General Morando.
  • The Good King /The High Queen: They are both beloved by their people for being just and fair rulers.
  • Royals Who Actually Do Something: When General Morando and his troops are outside their palace, they are at the front lines of defense, ready to fight them off to protect their children.


Akiridion Allies

    Varvatos Vex 

Varvatos Vex
Click here to see his true form. 
Voiced by: Nick Offerman

The zealous and battle-hungry commander of Akiridion-5's military force the Taylon Phalanx and Aja and Krell's bodyguard. On Earth, he is disguised as an elderly human man who acts as a protagonist along with the royal siblings in 3Below.

  • Alliterative Name: Varvatos Vex.
  • The Atoner: He is the one who allowed General Morando to attack Akiridion-5 by lowering the shields, though he had been promised no one would be hurt. His guilt over this action has led him to protect Aja and Krel with even more zeal than normal.
  • The Big Guy: In his normal form.
  • Blood Knight: If it's not about killing, maiming, or torture, he's not interested. He does, over time, gain an interest in the strategy of chess and becomes very supportive of Aja and Krel's Earth hobbies, even if they aren't for him.
  • Boisterous Bruiser: Varavatos Vex is almost always boisterous and loud regarding absolutely everything.
  • Broken Pedestal: He's on the receiving end of this when Aja, Krel, and Zadra discover he was the traitor who lowered the planet's shields, allowing General Morando and his forces to take over the planet.
  • Brought Down to Badass: By his own admission, he's not as strong in his "feeble human form" as he is in his original self, but he's still capable of fairly absurd feats of strength (like stopping a moving car with his bare hands).
  • But Now I Must Go: He returns to Akiridion-5 alongside Aja and Zadra.
  • Catch Phrase: "Glorious."
  • Extra Eyes: He has four eyes in his true form, but has a normal pair while in human form.
  • Death Seeker: He speaks often about his hope for an honorable death in combat and meets the potential of dying with glee. It's unclear if he's always been so eager for it or if the loss of his family and his guilt over betraying the royals has just pushed him further towards seeking it.
  • Didn't Think This Through: An usurper known for being murderous offers to let him avenge his family if he just betrays the royals whom he serves. Vex actually believes Morando when he says no one will be hurt in the coup. Guess how well that turns out.
  • Heroic Sacrifice: Vex is obsessed with "dying gloriously" for the Royal Family, which would entail this. He attempts to do this in the finale of Part 1, but survives and is taken away by Zeron Alpha.
  • Karmic Transformation: In hindsight, this applies when we learn he betrayed the royal family. His earth disguise is being an old man that isn't taken seriously by anyone on Earth. Vex feels the disrespect but has to use his head to think through situations.
  • Large Ham: Everything he says and does is ridiculously over the top and loud.
  • Laughing Mad: His bloody threats are usually punctuated by maniacal laughter. He also tends to laugh when fighting.
  • Mars Needs Women: Develops a crush on Toby’s Nana, Nancy Domzalski, whom he refers to as a “silver-haired temptress”. Seeing her for the first time even triggers a Fantasy Sequence.
  • No Indoor Voice: He tends to shout most of what he says at the top of his lungs.
  • Revenge Before Reason: Out of bitterness over the King's and Queen's decision to fortify Akiridion-9's defenses in response to the Zeron Brotherhood's attack that killed Vex's family instead of allowing him to pursue the bounty hunters in retaliation, Vex is tempted by Morando's promise of an opportunity to avenge his slain relatives in exchange for helping him take control over their planet.
  • Smart People Play Chess: Varvatos uses it as an outlet for his bloodlust, but does get to make the comment or two on his relative place on the chessboard. Namely, as a sacrificial pawn to save the King and Queen.
  • Scatterbrained Senior: Trying to be a seasoned warrior in an old man's body invokes this image. Detective Scott overrides him saying he's in charge of Aja and Krel because Vex's antics— trying to lift a shop building and later a bench — make him think that Vex is too incompetent to care for them.
  • OOC Is Serious Business: The only time he drops his Third-Person Person shtick is when he's at his most somber.
  • Phrase Catcher: "That guy is intense."
  • Third-Person Person: Oddly enough the only one of the race who does it. The only time he doesn't use it is when he wants to be very serious in his words.
  • Will Not Tell a Lie: He insists on maintaining honesty at all times. However, that doesn't stop him from doing so if he feels it is necessary to fulfill his duties.
  • Younger Than They Look: Invoked; he's actually a fairly seasoned warrior but is given the disguise of an old man with back problems.

    Lieutenant Zadra 

Lieutenant Zadra

Voiced by: Hayley Atwell

Commander Vex's second in command. She stayed behind in order to give the royals a chance to escape.

  • Action Girl
  • All Women Love Shoes: Accidentally orders a pair of red boots, upon seeing them in person its love at first sight and she never takes them off despite not actually having feet.
  • Ascended Extra: Her scenes are largely regulated to the political situation on Akiridion-5 but joins the main party on Earth at the end of season 1, stranded like the rest of them.
  • Broken Pedestal: Her faith in Vex shatters when she discovers that he was the traitor who lowered the planet's shields.
  • But Now I Must Go: She returns to Akiridion-5 alongside Aja and Vex.
  • Heroic Sacrifice: She attempts one in the pilot, but the villains manage to capture her alive.
  • Honor Before Reason: Subverted. She was prepared to die fighting off Morando's men to save the children. Later, she makes no bare bones of her hatred for Morando as he asks her to join him and that is not a request. Zadra, however, is scared that the kids are in danger and decides the best way to save them is to find out what Morando knows and sabotage him.
  • Iconic Outfit: Season 2 has this with the red boots she bought.
  • Join or Die: Morando tells her to do this — become his lieutenant, or he will torture her to death until she agrees. Her doctor tries to smuggle her out as thanks for Aja saving her child, but Zadra realizes that pretending to work for Morando is the best way to rescue the kids and stop him. She instead agrees to work for the Resistance as a deep-cover mole.
  • Mama Bear: Part of the reason she agrees to be a Reverse Mole is to try and find Aja and Krel to keep them safe and sabotage Morando.
  • Red Herring: It's implied at first that she is the mole when Zadra stays behind to fight off Morando's men. It turns out her loyalty to the royals has never been in doubt and she pretends to be a mole to save the kids.
  • Refuge in Audacity: Zadra takes advantage of this. Morando believes that due to her willingness to die for the royals that he would be able to break her will into agreeing to serve him. He underestimates that she would pretend to agree and stand by his side so as to sabotage his quest.
  • Reverse Mole: She agrees to work for Morando as the new commander of the Taylon Phalanx, but only so she can gather intel on the whereabouts of Aja and Krel, as well as finding out who the traitor that lowered the shields is. She wears the Resistance ring as a Trust Password.
  • Sinister Scythe: A good person, but her main weapon is a double-ended scythe.
  • Spin to Deflect Stuff: She can spin her weapon to deflect attacks, be they physical or energy.
  • Sword Beam: Her scythe can fire projectiles when swung.
  • Undying Loyalty: An utmost devout ward of the Royal Family.

Voiced by: Frank Welker

Princess Aja's alien dog. On Earth, he is disguised as a Corgi.



Voiced by: Glenn Close

The A.I. for the most high tech ship in the galaxy.

  • Benevolent A.I.: Mother is very protective and helpful to Aja and Krel.
  • Brainwashed and Crazy: Omen takes control of Mother in the series premiere's climax.
  • Grew Beyond Their Programming: Much like the blanks studying earth culture made her more emotional than she was at the beginning, especially in season 2.
  • Heroic Sacrifice: She eliminates herself in order to save Aja and Krel's parents.
  • Team Mom: Mother is caring, sweet and mindful of everything the family is doing and trying to help them and keep them safe.

    Dadblank and Momblank 

RK-Y and LU-C / Ricky and Lucy Blank

Voiced by: Tom Kenny (Ricky) and Cheryl Hines (Lucy)

Blank robots reformatted by Krel into fake parents.

  • Grew Beyond Their Programming: After taking a hit, Ricky starts pondering about his existence, this leads him and Lucy to eventually become a little more than just robots but do actually develop some emotions for each other and the kids.
  • I Choose to Stay: After Krel decides to remain in Arcadia, Ricky and Lucy deide to stay as well.
  • Mama Bear: In the first instance of Grew Beyond Their Programming, Lucy interrogates Stuart about threatening her "kids".
  • Papa Wolf: Ricky, following Lucy's example, interrogates Stuart about what he knows about the children.
  • Shout-Out: Their names are a nod to Ricky and Lucy Ricardo, a famous 1950's sitcom couple from the hit show I Love Lucy.

Voiced by: Jennifer Hale

A member of the rebellion. Her daughter was saved by Aja during Morando's attack.

  • Heroic Bystander: She's the doctor treated a captive Zadra and offers to smuggle her out to get her to the Resistance. When Zadra says she needs to sabotage Morando from the inside out, Izita gives her an insignia ring that serves as a Trust Password so the Resistance knows what Zadra is doing.
  • I Owe You My Life: She stays loyal to the royals thanks to Aja saving her daughter from collapsing rubble during Morando's attack.

    Loth Soborian 
Voiced by: Chris Obi

A seemingly non-Akiridion alien who is the royal adviser of House Tarron. Following General Morando's hostile takeover, he is coerced into helping Morando in his tyrannical endeavors.

Earth Allies

    Steve Palchuck 

Steve Palchuck
Voiced by: Steven Yeun

The resident bully, suspicious of the weird things Jim does.

  • Abusive Parents: It is implied by Coach Lawrence that Steve's hostility was a result of a verbally abusive dad.
  • Adaptation Name Change: Goes from "Steve Jorgenson-Warner" from the book to "Steve Palchuck" in the show.
  • Adaptation Species Change: By the end of the original novel, Steve was revealed to be a changeling. In the show, however, he is fully human, proven when he was hit in the head with Jim and Toby's horseshoe onstage and didn't change.
  • Amazon Chaser: Immediately falls for Aja after she kicks his ass.
    Steve: [Internally] Woah! She's like a ninja-kicking angel. I mean, she— she kicks ninjas, but she's an angel.
  • Arbitrary Skepticism: Even after the Season 2 finale of Trollhunters brought him face-to-face with the supernatural, he scoffs at Eli's claims that extraterrestrials might be living among them.
    • Lampshaded in the 3Below series finale: when approached by a talking cat warning about the doomsday, Steve's first reaction is to ask why he wears glasses. When Toby asks why he doesn't question how the cat can talk in first place, Steve answers he has already seen weirder things happen.
  • An Axe to Grind: In Wizards, he gets an axe made from one of Nimue's teeth. There's nothing special about it aside from it being a giant monster tooth, but it's something at least.
  • Barbaric Bully: Within minutes of their first meeting, Steve's calling Jim out for a beating after school. When outright fighting Jim is out of the question, he employs increasingly esoteric and deranged methods to torment him.
  • Big Ol' Eyebrows: Has thick, brown eyebrows.
  • Bullying a Dragon: He torments and ridicules Jim constantly, more then a few times Jim has thought about decking him but is able to resist for the most part. It should be noted that Jim has more or less tempted Steve to bully him because whenever Steve went after kids actually weaker than him Jim would always step in.
  • Butt-Monkey: In Wizards he spends most of his screentime being humiliated in several creative ways.
  • Catch Phrase: "Butt-snack," his preferred insult.
  • Character Development: Steve, hands down, gets the most development of any character in the show. He starts off in Trollhunters as your typical Jerk Jock bully, picking on anyone he deems weaker than him. Slowly though thanks to the increasing weirdness of Arcadia we see him become friends with Eli, tone down his bullying ways significantly, and a secret protector of the heroes.
  • I Choose to Stay: Aja invites Steve to join her on Akiridion-5, but he decides to stay because he can't leave his family.
  • Curtains Match the Window: Steve has both brown hair and eyes.
  • Do Not Go Gentle: In the Bad Future, his last moments involve fighting a winged troll as it carries him off into the night.
  • Dumbass No More: A more mundane example; he starts off as a typical Dumb Jock and Jerk Jock, usually having no survival skills whatsoever. Realizing there's weirdness in Arcadia, however, motivates him to shape up to stay alive and take down supernatural threats. He goes from someone that tries to run Jim off the road to a quick-thinker that gets parasols and blankets to protect trolls from the sun.
  • Fire-Forged Friends: With Eli in "Creepslayerz" as they form the titular team while investigating the strange, possibly dangerous creatures in Arcadia. At the same time, they also form a genuine, if vitriolic, friendship.
  • For Want of a Nail: In the Bad Future that Jim saw, he ends up as Romeo and kissing Claire onstage. Jim witnesses Steve's last moments as taking down invading Gumm-Gumms and dying in the attempt.
  • Freudian Excuse: It's implied he's a jerk because his dad was an emotionally abusive deadbeat. He gets better about this when admitting that he prefers his mother dating Coach Lawrence and realizing that Jim isn't his enemy.
  • Genre Savvy: When Jim calls them for aide in protecting the evacuating Trolls from the sunlight, Steve candidly likens it to the same weakness shared by Vampires.
    Steve: Ah, like vampire rules!
  • Hidden Depths:
    • Dim as he may seem, he's got enough brains and acting ability to land the (understudy) role of Romeo in the school play. Furthermore, he has enough acting ability to completely con Jim in the Truck-a-thon, and when auditioning for Krel's role in Toby and Eli's movie his talent brings his audience to tears. It says a lot that even though the role was written for Krel, and Krel was already filming it, the Director was seriously considering recasting and starting again.
    • While he initially comes off as crybaby blowhard, Season 2 shows he has a noble, brave side.
    • While embarrassed by him, Steve confesses that he really does see Coach Lawrence as the good father-figure he never really had.
  • Jerkass: He's an unrepentant bully, though he eventually grows into a Jerk with a Heart of Gold as he learns to care for Eli and Aja and even Jim, to a degree.
  • Jerkass Has a Point: Wearing a diaper to the Touch-A-Truckathon might be disgusting and undignified, but it manages to give him a legitimate edge for much of the competition.
  • Jerk with a Heart of Gold: Season 2 proves that deep, deep down, Steve has the capacity to be brave and selfless and befriend others. He maintains a strong friendship with Eli in the rest of the series and starts dating Aja when they meet.
  • Long-Distance Relationship: As Aja returned to her home planet, they decide to try a really long-distance relationship.
  • Love at First Punch: Or kick in this case, but Steve falls head over heels for Aja after she kicks him several feet for hitting her brother.
  • Parent with New Paramour: His father is out of the picture and his mother is now dating Coach Lawrence, putting a strain on his relationship with his formerly favorite teacher. Steve eventually admits, however, that he prefers Coach Lawrence because at least the man tries to be his friend and is better than his real dad.
  • Seen It All: By the 3Below finale, it's clear that nothing out of the ordinary surprises him anymore.
  • Secret Keeper:
    • In "Creepslayerz", Steve is this in regards to Eli's Embarrassing Middle Name.
    • He promises to keep Aja's secret once she reveals her true form to him.
  • Secret Secret-Keeper: Becomes this in "Creepslayerz" as he and Eli realize that Jim is somehow connected to all of the weird activity in Arcadia, but keep it quiet because they know that whatever Jim's secret is, he's on the side of good. He graduates to a Secret Keeper with Eli in the season two finale, when Jim finally cuts the pretenses and asks Steve for help saving Trollmarket refugees.
  • Sensitive Guy and Manly Man: After forming a friendship with Eli in "Creepslayerz", they become this as Steve is the brash, insulting Manly Man to Eli's nice, polite Sensitive Guy.
  • Sixth Ranger: Steve becomes a helping hand for the Trollhunters when he and Eli find out the whole truth. He continues this role in 3 Below, helping the Royal Family, though that has a lot to do with his attraction to Aja.
  • Took a Level in Kindness: It doesn't happen until the second half of season two when he witnesses Jim fighting a monster and declaring he's protecting Arcadia. Realizing that he read Jim all wrong, Steve resolves to help in any way he can and reforms his character. What's more, he finally tells Coach Lawrence that he's happy to have him as a friend even if he's not ready for another father-figure.
  • Wounded Gazelle Gambit: During Jim and Steve's fight in "Airheads", Steve breaks down, claiming that Jim keeps winning over him and that he feels like he's losing everything. When Jim feels sorry for him and forfeits, Steve immediately snaps out of it and mocks him for falling for it.
  • Wrong Genre Savvy: When he, Aja and Krel are abducted by bounty hunters, he assumes that all aliens are the "brain-sucking/probing" kind, making Aja apprehensive when she decides to reveal herself.

    Elijah "Eli" Leslie Pepperjack 

Elijah "Eli" Leslie Pepperjack
Voiced by: Cole Sand

One of Jim's classmates who is out to prove the existence of Trolls.

  • Adorkable: He's nerdy, somewhat shy, wears Nerd Glasses, a Nice Guy, and has a love of the 1980s era.
  • All of the Other Reindeer: Eli is a frequent victim of Steve's bullying and doesn't seem to be well-respected among his peers.
    Eli: I have friends!
    Girl: No, you don't.
  • Badass Driver: He can't parallel park normally, but can do so via "Tokyo Drifting".
  • Because You Were Nice to Me: Eli is initially skeptical of Steve's theory that Jim is an evil shapeshifter with plans for world domination because Jim was one of the few people to be genuinely and consistently kind to him. He's relieved to find out that Steve was wrong.
  • Brainy Brunette: Eli has black hair and appears to be quite intelligent.
  • Butt-Monkey: He's picked on by Steve, not well-respected among his other peers, and sometimes is caught up in Jim's Trollhunter life.
  • The Cassandra: Eli is the only one who knew about the various supernatural anomalies that populate Arcadia, but of course nobody believes him until Steve manages to capture a goblin routing through his trash, and even then Steve does not believe him that there are aliens there as well. This finally gets averted in the Trollhunters season 2 finale.
  • Embarrassing Middle Name: His middle name is "Leslie".
    Steve: [Chuckles] Leslie? Guess we both have a secret.
  • Fire-Forged Friends: With Steve in "Creepslayerz" as they form the titular team while investigating the strange, possibly dangerous creatures in Arcadia. At the same time, they also form a genuine, if vitriolic, friendship.
  • Let's Get Dangerous!: If hero duty or Jim calls, Eli is always ready to help. When Gunmar staged his invasion of the human world, Eli suited up with wheelies and prepared to distract the Gumm-Gumms away from innocent people. It helped buy time for the Trollhunters to dive into combat.
  • Locked Out of the Loop: Played With, Eli isn't privy to the details but he is aware of the presents of Trolls, Aliens, and Wizards. At least for the former, he got to interview the trolls personally after helping to evacuate them. In fact, he is the only one aware of all three.
  • Mistaken for Gay: In season 2 of 3Below, it's suggested that Toby has mistaken Eli and Steve's friendship for dating at least once before.
  • Momma's Boy: Shows some hints of this - on more than one occasion he's talked back to his mom, only to be immediately contrite when she responds with a Full-Name Ultimatum.
  • Nerd Glasses: Wears big, black glasses.
  • Nice Guy: He's shown to be consistently polite and friendly.
  • Secret Keeper: In "Creepslayerz", Eli is this in regards to Steve's mother dating Coach Lawrence.
  • Secret Secret-Keeper: Becomes this in "Creepslayerz" as he with Steve realizes that Jim is somehow connected to all of the weird activity in Arcadia but keep it quiet because they know that whatever Jim's secret is, he's on the side of good. He and Steve later become full-blown Secret Keepers and Jim's allies in the season two finale.
  • Sensitive Guy and Manly Man: After forming a friendship with Steve in "Creepslayerz", they become this as Steve is the brash, insulting Manly Man to Eli's nice, polite Sensitive Guy.
  • Sitcom Archnemesis: Acts as one to the Tarrons in the first season's initial quarter as they're afraid he'll out their true natures to the rest of the town. They eventually realize that he's harmless and, more importantly, no one believes anything he says anyway.
  • Sixth Ranger It's safe to say they're finally in the loop after the Season 2 finale. They are ready to help the evacuation when Jim finally calls for their aide and is exposed to Trollkind.
  • Smart People Wear Glasses: Eli wears Nerd Glasses and is quite smart.
  • Throw the Dog a Bone:
    • After spending an entire episode in the middle of a fight between Steve and Jim, he manages to win the Truck-A-Thon just by avoiding their punches.
    • In the Trollhunters season 2 finale, Jim calls him and Steve for help in evacuating the trolls from Gunmar's coup. Eli is thrilled that he gets to be a hero and that he'll finally get answers to all of his questions.
  • Took a Level in Badass: In a Meaningful Background Event: he is shown easily climbing a rope in gym and then backflipping back to the ground.
  • Vocal Dissonance: Despite being a teenager, Eli has the voice of someone in middle school or earlier than that. This changes in 3Below season 2 when his voice deepens.


Stuart in alien form

Voiced by: Nick Frost

A helpful alien the three meet who has been living on Earth for 30+ years. He hails from the planet Durio, known for being the smelliest planet in the universe, and occasionally helps the heirs when they have an Earth problem.

  • Adorkable: He is a huge admirer of royal families of the galaxy and becomes endearingly giddy when he discovers who Aja and Krel are, as House Tarron is his favorite among royal dynasties.
  • Aliens of London: He has a very pronounced English accent.
  • Ascended Fanboy: He's a huge nerd over galactic royal families, but by far he loves House Tarron. He takes great delight that he is now friends with Aja and Krel and helping them on their mission to return home.
  • Crouching Moron, Hidden Badass: For all his goofiness, he apparently managed to break out of a heavily guarded military base, with walls wired with bombs among other threats. And then willingly goes back to break out his old friend Buster.
  • Extra Eyes: He has four eyes in his true form.
  • Meaningful Name: He's from the notably stinky planet Durio 3 and is, therefore, a Durian. Anyone who has been near the Durian fruit knows only too well just how pungent they are.
  • Nice Guy: Stuart is an amicable and pleasant alien who is always willing to help out the Royal Family.
  • Recurring Extra: For Trollhunters as the owner of the town's most popular Taco truck. He even gets his name-dropped, or at least his store does, in the second episode when Jim and Toby are running from Bular.
  • Shipper on Deck: Seems to be this for Steve and Aja.
  • Signature Scent: Despite being on Earth for 3+ decades, he comes from the stinkiest planet in the galaxy. Even he knows how bad it smells and has a metaphor about it.



A large, insect-like alien imprisoned at Area 49-B alongside Stuart until he (Stuart) escaped.

  • Fluffy the Terrible: Of all the names this alien could have, "Buster" is the last one anyone would think he would be called.

General Morando's forces

    General Morando 

General Morando
No place for the royals can hide as beyond my reach.
Voiced by: Alon Aboutboul

An evil, tyrannical dictator who takes over Akiridion-5 and serves as the main antagonist of 3Below.

  • 0% Approval Rating: Nobody likes him and he doesn't care. He doesn't want his subjects' love or loyalty, just their obedience.
  • Alien Invasion: Morando led a coup d'etat on his homeworld, and took over it for his own diabolical purposes. He also wants to invade Earth.
  • Bad Boss: When Krel and Aja escape, he kills the person that brought him the news.
  • Big Bad: He is the main reason that the main characters escaped to Earth and the one who directs the bounty hunters to hunt them.
  • Collapsible Helmet: He is seen wearing a helmet when he makes his introduction in the first episode, which he deactivates, causing it to disappear Star Lord style.
  • Deity of Human Origin: He manages to get a hold of Gaylen's core and become a god in the process. He, however, is destroyed before his power grows enough to recreate the universe as he planned.
  • Evil Overlord: He takes a very hard stance against the citizens of Akiridion-5; worship him or die.
  • The Exile: Was exiled before his coup at the start of the series.
  • Extra Eyes: Much like Vex, he has four eyes.
  • Faux Affably Evil: Whatever politeness he exudes does little to conceal the bastard that he is underneath.
  • Galactic Conquerer: Morando wants to make Akiridion-5 a galactic superpower with him at the helm.
  • Godhood Seeker: When he finds out that Gaylen's core is somewhere on Earth, he changes his motives to getting it with the intent of becoming a god and remaking the universe in his image, killing the royals and ruling over Akiridion-5 becoming mere perks in comparison.
  • Jerkass: He is, simply put, a massive and vicious asshole.
  • Knight of Cerebus: He's a power-mad dictator whose overthrow of house Tarron and Akiridion-5 is played completely seriously, and his attempts at ending the royal family make him just as menacing.
  • Manipulative Bastard:
    • Convinced Varvatos to betray the House of Tarron by telling him that no one would be hurt. In fact, to make sure Varvatos accepted his offer, it was HIM that hired the Zeron Brotherhood to kill Varvatos' family, causing Varvatos to be bitter at the royals who refuse to give chase to the ones who did it.
    • Convinced Kubritz that he would NOT harm the Earth as long as he gets what he wants, and even gave her some weaponry to protect Earth. It takes him rampaging across Arcadia at the size of a kaiju to make her realize he's going to destroy Earth along with the rest of the universe.
  • One-Winged Angel: In "A Glorious End, Part 1", Morando absorbs Gaylon's core and transforms into a giant god-like alien monster that is unstoppable.
  • Orcus on His Throne: In the first part of the series premiere, Morando is content to send bounty hunters after Krel and Aja while he solidifies his take-over of Akiridion-5 and builds new superweapons. This changes when his attempt to broadcast the deaths of the royals fails, and he plans to head to Earth soon.
  • Satanic Archetype: His primary color motif is deep, seething red, his head is shaped in a manner that evokes horn imagery, and his goal is to become a god and remake the universe in his own image. Morando's favorite cardinal sin seems to be treachery, as he betrayed his King and Queen to start a coupe and take the crown for himself under a fascist dictatorship, he convinced Varvatos to betray them for him (even having engineered his family's death to make him more willing) and he promises to help Colonel Kubritz defend the Earth by providing advanced weaponry with every intention to destroy the Earth when he is done with it. Even Kubritz's Sergeant describes their deal with him as "a Deal with the Devil."
  • The Sociopath: A cruel, power-hungry dictator who is Chronic Backstabbing Disorder incarnate and is willing to pursue his goals at any cost, even if it means screwing over his allies in the process.
  • The Usurper: An illegitimate ruler who usurped the righteous rulers of Akiridion-5.
  • What the Hell Is That Accent?: Morando speaks in an odd, hard to identify accent (a fruit of his VA's hybrid accent, originated due to being an Israeli with French-Algerian and Egyptian ancestry).
  • You Have Failed Me: He executes Tronos Madu for failing to take down the Royals.

Bounty Hunters

    The Zeron Brotherhood 

Voiced by: Darin De Paul (Alpha) and Ann Dowd (Omega)

A trio of ruthless bounty hunters who will stop at nothing to claim their prize, not even killing innocent civilians.

  • Cats Are Mean: Beta.
  • The Dreaded: Even Vex is wary about the thought of facing them.
  • Even Evil Has Loved Ones: Despite their evilness, they care deeply for each other and actually seek revenge for being hurt.
  • The Heavy: Morando is the one that commanded them to go after the royal aliens, but he is far away from Earth to actually act on anything, leaving the brotherhood to do most of the damage and be most of the problems faced by the royals.
  • No Kill Like Overkill: The Zerons once bombed an entire civilian building, killing hundreds of innocent people just to claim a single bounty.
  • Reptiles Are Abhorrent: Omega.
  • Shout-Out: Alpha's design and clothing greatly resemble several depictions of Anubis.
  • Theme Naming: They are all named after Greek letters. The wolf is Alpha, the cat is Beta, and the lizard is Omega.
  • The Unfettered: Nothing will deter them from fulfilling their contract, even if that means they leave behind a high body count

Voiced by: Fiona Shaw

A mysterious birdlike bounty hunter who infiltrates Arcadia in order to hunt down the royals.

  • Bird People: Halcon has several birdlike attributes such as flight, squawking when she speaks, and not being able to see glass. Her human disguise even uses "Birdie" as a nickname.
  • Cold Sniper: She is a deadly marksman who would've shot Krel's core out of his body had Dadblank not blocked her shot with his briefcase
  • Flight: She is capable of flying at fast speeds despite lacking any wings.
  • Foil: She is one to the Zeron Brotherhood in terms of how they pursue targets. While both are ruthless and willing to fulfill their contracts by any means necessary, the Zerons don't give a rat's ass about who or what gets in the way of collecting their money and are all too willing to destroy an entire civilized area just to take down one target, as shown by their bombing Commerce Guild that slew Vex's family. On the other hand, Halcon opts for the tactic of "research and destroy", studying her targets either from a distance or in disguise until she finds the right moment to strike.
    • She is also a foil to Vex, as both of them are blue-colored aliens and lethal warriors armed with serrators who pose as elderly citizens on Earth. But while Vex is a noble-natured yet zealous warrior who takes time to understand human customs, Halcon adapts to Earth culture much faster, posing as a strict member of the special advisor to the school board who uses her deception to learn where the royals are hiding out.
  • Racist Grandma: Her human disguise comes off as this, being scathing and suspicious of Aja and Krel due to them clearly not being from the United States to the point where Senior Uhl tells her to lay off them
  • Obstructive Bureaucrat: She gives Aja and Krel a ton of paperwork to fill out to prove they're U.S. citizens, but that's only so she can find out where they live to ambush them and take their parents' cores.

Voiced by: Fred Tatasciore

A large, violent, trash-talking bounty hunter who is a member of a race of mechanized, magma-fueled beings called Cindorites from the volcanic planet Cindor. He comes to Earth in hopes of collecting the bounty placed on the Tarron Family but faces resistance from Aja, Krel, Zadra, and their human allies.

  • Drop the Hammer: his signature weapon is a massive, double-headed hammer with jet thrusters built into each head to increase its blows and return to Magma-Tron if thrown
  • Hoist by His Own Petard: He's destroyed by being smashed between the two halves of his severed hammer.
  • Weaksauce Weakness: He's weak to water and easily stops in his tracks when a sufficiently big amount of water hits him.

    Tronos Madu 
Voiced by: Danny Trejo

An electrothermal lifeform from the planet Voltar that hunts for the royals partly out of a desire to win the bounty on their heads but also out of revenge because their mother and father would not come to his planet's aid when it was being destroyed by a civil war.

  • Heel–Face Door-Slam: Aja convinces him that they can be better than her parents. Since they didn't help him save his planet, she asks him to save Earth, now that their places are swapped. After helping Aja and Krel escape, he's recaptured and subsequently killed by Morando.
  • Impaled with Extreme Prejudice: He gets killed by Morando when he comes to Earth, being pierced by Morando's sword as soon as he figures out he helped the Tarron family.
  • It's Personal: Aja and Krel's parents refused to help him when his planet was being destroyed by civil war, he takes it personally to end Aja and Krel's lives, therefore.
  • Reptiles Are Abhorrent: His physical form resembles a large, menacing lizard.
  • Shock and Awe: His body is made out of electricity and it can spew lightning when attacking.

Voiced by: Kathleen Turner

A hulking bounty huntress from the planet Gorbon who is also Stuart's ex-girlfriend.

Voiced by: Tom Kenny (the Destroyer) and Matthew Waterson (all other Foo Foos)

A species of small, rabbit-like, mechanical beings. They reproduce quickly and are all bounty hunters working together.

  • Explosive Breeder: While no outright stated, it is heavily implied that they are this.
    Varvatos: How are there always so many of you? Varvatos destroyed scores of you on the moon
    Foo-Foo: You left two of us alive.
  • Killer Rabbit: They're cute, small rabbit-like beings that are dangerous bounty hunters.
  • Mr. Seahorse: They can reproduce even if there are only two males.
  • One Steve Limit: Inverted. All of the Foo-Foo's are named "Foo-Foo" in a Gang of Hats sort of way, differentiating by their "The Magnificent" titles.
  • Phrase Catcher: They're often questioned about how they reproduce so quickly.
  • Punny Name: All Foo-Foo's are named "Foo-Foo" the Adjective, and are experts at fighting. In other words, they are Foo Fighters.
  • Wild Card: They have loyalty only to who's currently paying them, while they spend most of the series fighting the royals for a bounty, just paying them is all it takes to make them allies.

Other Humans

    Phil and Jerry 

Phil and Jerry

Voiced by: J.B. Smoove (Phil) and Reginald VelJohnson (Jerry)

Two humans who are Varvatos' chess buddies.

    Colonel Kubritz 

Colonel Kubritz

Voiced by: Uzo Aduba

The colonel in charge of observing all the alien life of Area 49-B.

  • Absolute Xenophobe: Has a strong hatred for aliens and alien life, seeing them as potential specimens/test subjects at best or outright threats at worst. Interestingly, she knows of the existence of trolls but seems to pay no mind to it.
  • Acrofatic: She's not exactly overweight, but she's not thin either. Doesn't stop her from fighting hand to hand with Aja and winning.
  • Actor Allusion: Uzo Aduba is known for playing Bismuth from Steven Universe, a Well-Intentioned Extremist alien. Here she is cast as a Not-So-Well-Intentioned Extremist human who's agenda specifically targets aliens.
  • Asshole Victim: She dies in the finale, and no-one will miss her. She's so unpleasant that being Killed Mid-Sentence whilst pinned under a car and bleeding out seems like she got off light.
  • Ascended Extra: She only appears in a single episode in Season 1, but is a major villain in Season 2.
  • Ax-Crazy: Even before she allied herself with Morando, her sanity from her first debut was noticeably...not so good. She's definitely insane, insane enough to ally herself with the worst aliens in the galaxy, like Morando, just for more alien weapons and is willing to sell her planet to him just to get rid of the Tarron children. Costas even spells this out about how much Kubritz has completely sold herself to Morando's cause. After Morando presents her a battle suit of her own, her insanity reaches to the point where she open fires at innocent civilians when they stand against her accusations towards Aja and Krel.
    Costas: Colonel Kubritz has lost her mind!
  • Colonel Badass: She can hold her own against Aja after Vex had been training her.
  • Bad Boss: Sufficiently angry, she'll fire against her own men out of anger.
  • Black Boss Lady: Naturally.
  • Deal with the Devil: Invoked. Works alongside Morando in exchange for alien tech. Her lieutenant literally spells this out for her only for him to be ignored.
  • Double Standard: It turns out that she knew about the trolls that live beneath Arcadia - her predecessor having referred to Trollmarket as "the Underneath" - yet she seems to be completely unconcerned with it. Even after Gunmar and his armies broke to the surface and invaded the place, she seems to dismiss the trolls as irrelevant to her mission.
  • The Dragon: By season 2, to General Morando. She realizes he is likely to be or to become, the most powerful being in the galaxy, so she sides with him to protect her planet.
  • Expy: She takes some visual cues from Amanda Waller, a black, tough as nails government agent who isn't afraid to get her hands dirty.
  • Fantastic Racism: All aliens are, to her, evil invaders at worst and potential specimens at best. A couple of passing lines show she has a dislike for human aliens as well. Strangely enough, this does not seem to apply to trolls, Area 49-B having known about Trollmarket for a while but dismissing their presence as irrelevant to her mission.
  • Four Eyes, Zero Soul: She wears glasses, but is an Absolute Xenophobe.
  • Genre Blindness: Expects Morando to keep his promise to protect Earth and continues helping him despite it becoming increasingly clear that the guy is bad news. Aja even points out that he'll betray her once she's no longer useful, to which she insists that he swore to protect Earth.
  • Hate Sink: Given how she was willing to sell out her own planet to General Morando, it's clear that Kubritz was meant to be despised by the audience.
  • Heel–Face Door-Slam: Finally turns against Morando after seeing all the damage he was causing to Arcadia. After attacking him, she gets trapped under a car and subsequently killed by Morando's energy blast.
  • Horrible Judge of Character: She considers Aja, Krel, and Stuart to be "evil invaders" that need to be captured and imprisoned at all costs when really Aja and Krel are refugees and Stuart crash-landed there by complete accident. Yet she is willing to work with the Obviously Evil Morando and help him become a Physical God because he told her that he would conquer and/or remake the entire universe except Earth.
  • Hypocrite: For someone who claims she is just doing what's necessary to protect Earth from invaders, she is quick to side with alien criminals and power-hungry dictators just for the promise of weapons and tech.
    • Despite wanting to protect Earth, she's put Arcadia in danger multiple times searching for the twins and even threatens the citizens just for protecting them. Her claim as the "future supreme commander" of Earth also makes it clear she's just power-hungry.
    • She looks on in horror when Morando murders Tronos. The same Tronos that she imprisoned and tortured.
    • Despite reneging on every bargain she ever made throughout the series, she's visibly astounded that Morando would betray her. Apparently deals are hers to break... no-one else's.
  • Irony: Insists that all aliens are evil yet keeps teaming up with "bad" aliens like Tronos and Morando to go against "good" aliens like the Tarron twins. Aja even lampshades it.
    Aja: For a human who hates all aliens, you pick the worst ones to befriend.
  • Jerkass: Rude, crude, and downright abusive and hypocritical.
  • Karmic Death: She dies very very quickly in the finale. You don’t feel bad for her. She imprisoned, experimented on and tortured Stuart and Buster for decades, don't forget...
  • Killed Mid-Sentence: "It's never too late—"
  • Knight Templar: She is so paranoid at the idea of aliens coming to invade Earth that she considers all aliens on Earth to be Always Chaotic Evil, even if they simply crash-landed there by complete accident. Her narrow-minded desire to capture, contain and exterminate all of them is so bad that she is willing to declare martial law over a town of innocent civilians, willing to tear all of Arcadia apart (and the innocent civilians there) just because Aja and Krel are there.
  • Mistaken for Racist: Weaponized. When she corners Aja and Krel while they're in their human disguises, she spouts things that, regarding immigrants, sound incredibly racist. When the rest of the students threaten to record her talking and make the video go viral, she backs down and gives up tracking them down that day.
  • Never My Fault: She blames Aja for all the chaos at the movie theater when she was the one who attacked the theater in the first place. And again when she blames Aja for everything due to not surrendering in the first place despite the fact that she was the one attacking Arcadia's citizens. Aja even calls her out for it.
  • Not-So-Well-Intentioned Extremist: At first it just looks like she wants to protect Earth from any otherworldly presence that could potentially pose a threat. As the series progresses however, the lengths she goes to to capturing the Akiridions - cutting deals with more Obviously Evil aliens, breaking promises left and right, endangering Arcadia's human population - shows that she isn't interested in any common good and is just a sociopathic, opportunistic Hypocrite with government funding and a small army at her command.
  • Tautological Templar: She believes that she is helping keep the planet and humans safe, therefore, all her actions, even the ones where she harms humans or put the planet under the sight of Morando, are protecting humans. Aja calls her out on it.
  • Token Human: She is the only human antagonist in the series, as well as the first entirely human antagonist in the Tales of Arcadia franchise. Morgana in the previous series looks human, but Merlin states that she is something else.
  • Would Hurt a Child: Aside from being absolutely willing to kill an alien teenager, like Aja and Krel, she has no problems obliterating and torturing their human friends, like Steve, Toby, and Eli.

    Sergeant Costas

Voiced by: Oscar Nuñez

Kubritz's second-in-command.

  • Anti-Villain: He's nowhere near as despicable, prejudiced, or hypocritical as his superior.
  • The Cassandra: Costas tries to repeatedly warn Kubritz that joining forces with Morando is a Deal with the Devil, but she doesn't listen.
  • Everyone Has Standards: Costas assists Kubritz in capturing extraterrestrials no matter if they're dangerous or not, but he has far more decency than his superior. The first sign of this is his shock at Kubritz going back on her deal with the Tarrons despite the fact that they helped save Earth from the asteroid in "Asteroid Rage". Then his increasing discomfort with his superior working with Morando eventually pushes him to defect to the Tarrons.
  • Heel–Face Turn: At the beginning of "A Glorious End - Part 1", he defects to the Tarrons to help them defeat Morando and Kubritz.
  • Hidden Depths: Costas has a good knowledge of electronics, allowing him to help Stuart build the mega-blaster to kill Morando.
  • Only Sane Man: He's well aware that working with Morando does not bode well for anyone.

Other Aliens

    Gaylen and Seklos 
Two ancient god-like beings. Gaylen was the creator of Akiridion-5, but as he grew more powerful he also grew fearsome, and Seklos used her own core to stop him.
