My name is Aja Tarron of House Tarron, and I want to tell you a story. It's a good story. It is very lively, with lots of humors and excitements: It begins someplace very, very, very far from here, on an entirely different planet called Akiridion-5... my brother and I were forced to leave our home. We are not like you, but we are like you... and you welcomed us, and your world became our world. We made many, many friends. And together, we embarked on adventures we'll never forget.
―Aja to the people of Arcadia Oaks[src]

Aja Tarron is one of the main stars in the Tales of Arcadia franchise, serving as the main protagonist of 3Below and a minor character in Part Three of Trollhunters (major in its upcoming film, Rise of the Titans).

She is the current warrior queen of Akiridion-5, a foreign exchange student of Arcadia Oaks High, best friends with Darci Scott and Mary Wang, the daughter of Fialkov and Coranda Tarron, the elder sister of Krel Tarron, and the current girlfriend of Steve Palchuk.

Physical Description

In her alien form, Aja has blue skin, long electric-blue hair, blue eyes, black sclera, and has four arms. She also has a ridge on her forehead which marks her as queen-in-waiting, which she received at the end of "Terra Incognita Part Two".

She wears a black and blue jumpsuit with neon blue linings. In Rise of the Titans, she wears armored paldrons, similar to her parents' and a neon blue cape.

In her human form, Aja has long, platinum blonde hair (which she usually wears in a low bun with side braids) and pasty white skin with freckles over her nose.

Her outfit consists of a red checkered button-up shirt, jeans, and red sneakers.


Tired of growing up and living the life of a princess, Aja felt like she didn't belong in the royal palace, frequently sneaking outside to experience the lives of commoners though she needed to wear a disguise to avoid attention. Even when it was her own coronation day, she decided to run away again with Luug, not wanting to be queen-in-waiting either.

However, when General Morando led a coup to overthrow her and family, Aja immediately feels guilty, and blames herself for putting her parents in stasis and her own planet in danger. Desperate to set things right, she decides to follow the path of a warrior so she can protect her family and take back Akiridion-5 from the evil, tyrannical hands of Morando, ignoring the fact that princesses aren't born to be warriors.

Aja seems to be more extroverted than her introverted younger brother, Krel, and has been described by her family as a "free-spirit", which shows her independence. She's amazed by Earth's customs and technology, and even longs for adventure and fighting on the battlefield as a warrior princess. She appears to be very skilled in terms of hacking into computer systems and seems to be a great dancer and singer as well, most notably shown when she and Krel participate in the Battle of the Bands.

However, despite her bubbly, adventurous mindset and competence in battle, Aja has shown overconfidence and recklessness in her abilities, and even fears of getting herself hurt. She is also somewhat impatient, and is easily frustrated when things don't exactly go her way; she later openly admits that this is because she doesn't want to lose anyone close to her ever again, after what happened with her parents, which shows her more caring nature. She later comes to terms with the fact that, despite all the training in the world she could receive, she cannot prevent every tragedy, as such becoming more serious and responsible, with the newfound knowledge that making mistakes and getting injured is inevitable, even for a warrior. Despite this, she can be easily distressed and provoked into fighting when someone very close to her gets in harm's way.

In Part Two, Aja becomes more responsible and determined to protect Earth as she's come to accept it as her and Krel's new home. After learning about her parents' dishonorable actions in the past, such as what happened in Voltar, Aja decides to fix her parents' mistakes and be a better ruler. She, along with Krel, were even willing to sacrifice their royal life cores to prevent their parents from dying again. In the end, after the sacrifice of her parents, Aja finally accepts her status as a royal and decides to rule Akiridion-5.

Powers & Abilities


  • Royal Akiridion Physiology: As a Royal Akiridion, Aja is much more stronger, faster, durable, agile, intelligent, and has better reflexes than an average human.
    • Enhanced Strength: Aja is shown strong enough to hold a heavy moon rock with no strain (while Steve, a jock, showed visible strain). She was able to kick Steve several feet away with one kick, as well as climb a tree trunk and rope with incredible ease.
    • Enhanced Endurance: Aja can endure more than an average teenager.
      • Enhanced Durability: Aja is able to withstand many blows which would mortally wound an average human, as she has taken hits and blows from many alien bounty hunters.
      • Enhanced Stamina: Aja can physically exert herself for long periods of time without tiring before fatigue begins to wear her down.
    • Enhanced Agility: Aja is much more agile than most Akiridions. She was able to flip and leap over cars and walls without slowing down. In "Party Crashers", she hopped down off a tree while landing perfectly on her feet. She was also able to climb onto a god-induced Morando with little to no problem. She could even do backflips while attacking her opponents, despite having just a single day of training with the blankbots.
      • Enhanced Leaping: Like Zadra, Aja is able to leap higher and further than an average human or Akiridion.
    • Enhanced Speed: Aja is faster than an average human.
      • Enhanced Reflexes: Aja is able to evade many attacks with ease, but often struggles due to her impatience.
    • Hypermetabolism: As an energy-based being who doesn't require organic consumption, Aja was able to digest an entire Diablo Maximus burrito with no digestive problems (while Toby stated that it took him three years to build a tolerance for a single bite), as shown in "Terra Incognita Part Two".
    • Extra Arms: As a Royal, Aja has four arms, which prove to be useful for multitasking and providing additional strength.
    • Vacuum Adaption: As an Akiridion, Aja can adapt and survive in any atmospheric environment without any aid, but a planet's gravity does still affect her, as shown in "Moonlight Run".
      • Oxygen Independence: Aja does not require oxygen to live, as shown in "Moonlight Run"
    • Longevity: As an Akiridion, Aja can most likely live for hundreds of years, but she is still vulnerable to death and can fall in battle.
  • Hacking Intuition (limited): As shown in the episode "In Good Hands", Aja is able to hack into Arcadia's local power grid in mere moments. She appears to share this trait with her little brother, but hers is clearly more limited than his.


  • Swordsmanship: Under the training of Varvatos and her own terms, Aja is a remarkable swordswoman and possesses great skills with a blade, possibly rivaling that of Jim Lake. She is shown to have great dexterity on her serrator and is able to hold her own against more experienced alien bounty hunters, even better than Krel.
  • Marksmanship: Aja was also shown to have great aim with her serrator when in blaster mode, as she was able to destroy to Zeron Brotherhood ship's stabilizer with a single blast.
  • Martial Artist: In comparison with her serrator skills, Aja is a highly skilled warrior and is fairly knowledgeable with hand-to-hand combat. Even before training with Varvatos, she was able to stand her ground against Zeron Omega with little to no struggle. She even fought against and evaded Omen, despite the latter being an advanced robot. She is shown to even be able to hold off the god-induced Morando and blind one of his eyes with solely the use of her hoverboard and serrator.
  • Adaptor: Like Krel and Varvatos, Aja was able to easily adapt with humans, but is constantly still confused by earth metaphors and culture.
  • Leadership: Aja is shown to be a natural leader, much like her parents. However, she's not exactly a master tactician and mostly prefers to improvise throughout her battles.
  • Vocalist: As shown in "Last Night on Earth", Aja is a decent singer while she participated in the Battle of the Bands with Krel.


  • Physical Damage: Despite her enhanced durability, Aja could be forced to retreat into her royal core if she ever suffered too much physical damage.
  • Impatience: Despite her excellent combat abilities, her impatience can let her enter combats without thorough tactical preparation, giving her opponent an upper hand, as seen in her solo attacks on Porgon and Tronos that almost ended up losing her own life in "D'aja Vu" and "Mother's Day", respectively.


  • Serrator: One of Aja's most common weapons is an Akiridion serrator, an ionic energy-type weapon. It's able to form into a nearly impenetrable shield, a blaster or bazooka, a sword-like blade, and a two-pronged spear for combat. She received her serrator on her 10th birthday. In Part Two, Krel modifies and enhances her serrator so it can allow Aja to change between her Akiridion and human form at will, strengthen its blasters, etc.
  • Hoverboard: Aja uses a hoverboard as her mode of transportation. It can form into a portable chip and can fit only two people, with Krel being her most common passenger. It can be disguised as a regular skateboard, as shown in "Luug's Day Out".
  • Mind Reader (briefly): Aja barrows Krel's mind reader to help him find the presumed alien spy in Arcadia. When she discovers that it was Stuart, she chases him down the streets, until she accidentally crashes into a lamppost and breaks the glasses.

  • Aja is the first (and only) female protagonist in one of the Tales of Arcadia installments (in this case, 3Below).
    • Although Krel is almost just as important, Aja is (technically speaking) the true main protagonist of the second installment.
  • Aja's voice actor, Tatiana Maslany, also voices Aja's mother, Queen Coranda.
    • Also, like her mother, she speaks with a kind of Russian accent.
  • She first appeared in the Trollhunters episode "In Good Hands", alongside her brother, Krel.
  • As revealed in "Collision Course", Aja's bounty is higher than Krel's, most likely due to her status as a warrior princess and being the eldest.
  • Although not officially confirmed, the name "Aja" may be based on the song of the same name by the band Steely Dan.
  • As explained by Aaron Waltke on Discord, Aja's greatest fear is the destruction of Akiridion-5 and Earth in a war they cause with each other.
