Prince Krel Tarron is one of the main stars in the Tales of Arcadia series. He first appears as a minor character in Part Three of Trollhunters and the deuteragonist of 3 Below.



Prince Krel lived on the planet, Akiridion-5 with his sister, Princess Aja and their parents, King Fialkov and Queen Coranda. While Aja often snuck off to have fun in the kingdom, Krel spent most of his time experimenting and studying Akiridion technology. The two often received lectures from their parents about their responsibilities they will have when they take over the planet, to which they often fell asleep.

On the day of Krel's coronation ceremony, he was assigned to battle their best fighter, Varvatos Vex, to show the kingdom his battle skills. Unfortunately, the battle is interrupted by General Morando and his evil henchmen, whom have come to take over the kingdom.

Part Three (Trollhunters)

Meeting the Trollhunter

Señor Uhl then brings Jim to the classroom to show them around the school if he wants to make up for his many absent days. Jim takes Aja and Krel to Claire and Toby, who reluctantly agree to include them in their Trollhunting mission for Merlin

They take them to the wrecked Janus Order, which they pass off as a "teen hangout." While they search for Changeling remains, Krel goes into the control room and starts to use the system to play music and show off his dancing skills. When Jim turns the music off, some footage of AAARRRGGHH!!! fighting Gunmar starts playing on the monitors, which he instantly turns off. The Trollhunters claim it to be a movie and decide to take the siblings to see Claire's house, while Krel takes something he brought out of the control panel. 

Jim and Toby go to the roof to collect some lightning in a jar, so Aja and Krel decide to use their vast intergalactic knowledge to help them do it. Krel makes a capacitor from some parts of the microwave to hold the lightning in, and Aja hacks into Arcadia's power grid to make lightning appear in fifteen minutes. Using Jim's sword, they manage to capture the lightning and put it in the jar. The siblings then bid their friends goodbye and go home. 

Part One (3 Below)

Morando's Attack

Krel calls Aja to check if she's going to their joined coronation, she explains that she has no intention of becoming Queen-in-Waiting. King Fialkov comes by to tell him that Aja will not be attending the coronation but he already knows. Krel finishes the device he makes to win the duel then his father gives him advice about being King and how nobody is ever ready.

Physical Appearance

In his alien form, Krel has electric teal blue skin, light-blue hair that spikes up, four arms, and a neon blue jumpsuit. He also has blue eyes and black sclera.

In his human form, Krel has tanned skin and fluffy dark brown hair. His outfit consists of a blue t-shirt with a light-blue squiggle, navy blue sweatpants, white sneakers, and a watch on his left wrist.


Unlike his older sister, Krel appears to be more stoic and introverted, often making snarky comments to his sister and everyone around him. Despite this, he appears to be an excellent disc jockey and loves to dance, and he is also quick-witted and curious about Earth. Krel often criticizes Earth's more primitive technologies, as they don't match his own. He's also shown impatience and frustration when he asks people about a Daxial Array, but they mistaken it as a band.

Krel seems like a loyal type, as he ventured with Eli to find the Billycraggle, despite his dislike of outdoors and annoyance to Eli's conspiracies, and felt deeply hurt and betrayed by Vex when he learns that he helped Morando invade Akiridion-5. Krel also willingly gives up his "A+" for Seamus after overhearing his and his father's argument.

While Krel's shown confidence in his ability to invent and understand technologies, he can doubt himself as he admits to Aja if he could ever fix the mothership by himself after it was damaged during their fight with Omen.

Powers & Abilities

Akiridion Physiology

As an Akiridion, Krel is stronger, durable, agile and much more intelligent than a normal human. He was shown durable enough to easily withstand a single punch from Steve (who is stronger than most of his classmates, but has no powers) without being knocked out cold, only managing a nosebleed (which is neon blue instead of human red). His agility and reflexes are more limited than Aja's, but is almost as fast as her.

Intelligence & Inventing

While Aja is more of a warrior, Krel's greatest strength is his intelligence and ability to invent new technology and weapons. He was able to craft special glasses designed to read minds with emoji-like figures over their heads and create a new Daxial Array for the Mothership with a few Earthly components.

He is also smart enough to ace every single test in his human classes with perfect scores. He even uses his own serrated shield to deflect all of the laser grids in Area 49-B instead of evading them like Vex did.


He is not as skilled in combat like his sister, but is clearly able to hold himself off against more experienced alien fighters with a serrator (mainly when it's a shield and a blaster).

Disc Jockey

Krel is considerably skilled with music, dancing, and DJ-ing, even blowing away the residents of Arcadia during the Battle of the Bands with his own music style.



A serrator is an Akiridion's most common weapon, being able to form into a nearly impenetrable shield, a blaster, a blade, and a two-pronged spear.

Mind Reader

In "Mind Over Matters", Krel invents his own mind reader in order to convince Eli that he and Aja are not aliens. Aja later uses this to find an alien imposter, but she accidentally damages the glasses, much to his dismay.

Krel's mind reader appears like some sort of virtual reality glasses. When in use, he is able to hear the target's thoughts while an emoji-like sign appears on their head. It can also be adjusted from hearing only one person per-time to hearing the whole town of Arcadia (which could cause the user to experience a small, brief migraine).



Aja is his older sister, who he cares deeply for. When they become stranded on Earth, he always remarks how he'll never be afraid as long as he has his older sister with him.

Varvatos Vex

As Krel's guardian and his father's friend, he sees Vex as a close friend. However, once he learns on Vex's betrayal, he immediately becomes enraged and hurt for his bad deeds jeopardizing his people's planet and almost executes him. Before Vex sacrifices himself to stop their mothership from leaving Earth, he apologizes to him and Aja for his actions and tells them that they are unstoppable together.

After Vex goes missing, Krel presumably seems to have shrugged off his grudge and becomes worried for his guardian's safety.


Luug is the royal family's pet. Krel clearly loves his loyal dog.

Queen Coranda

Coranda is Krel's mother. They have little to no interactions alone, but it's clear they have a loving relationship. He becomes greatly concerned when she was put into stasis and currently awaits her revival so they could return home.

King Fialkov

Fialkov is Krel's father. When Krel feels reluctant to become king-in-waiting, his father gives him fatherly advice about his choices. After Fialkov is put into stasis, he becomes worried and currently awaits his (and his mother's) restoration.

Eli Pepperjack

When Eli witnesses Krel and his sister in their true forms, he was against torturing Eli and decides to convince him he was only cosplaying, using a mind reader. Krel seems to tolerate Eli as a good person and friend, but is clearly annoyed and skeptic by his stereotypical conspiracies. Despite his annoyance, Krel decides to venture with Eli in the forest to find a Billycraggle and then tries to protect him from Zeron Omega when he attacks. In "Bad Omen", unaware to Krel or Aja, Eli takes a clear photo of them in their alien forms after the Eternal Night ends.
