Krax was a hidden antagonist of Trollhunters, featured in the Part Two episode "Mistrial and Error".

He was a Changeling spy that infiltrated Heartstone Trollmarket under the orders of Usurna.


Trollhunters (Part Two)[]

Krax is a Changeling that was put under the orders of Usurna by Gunmar. When Usurna infiltrated Trollmarket, Krax also arrived. He then purchased all the Gaggletacks from RotGuts so no one could reveal his human form.

He also made a cameo appearance (in human form) at the Nuñez barbecue party in the episode "Hero with a Thousand Faces". He was most likely there to keep an eye on the Trollhunter's activity.

When Blinky and Claire were searching for evidence of a spy in Trollmarket, they convinced Rot and Gut to reveal that Krax had bought all their Gaggletacks, which led them to deduce that he was a Changeling. While investigating Krax's house they found the Gaggletacks. Krax appeared and Blinky used a Gaggletack to reveal him as a Changeling. Blinky then tried to convince him to reveal who he was working for by activating a detonator stone, but Krax died in the resultant explosion.

Physical Appearance[]

In his troll form, Krax was a huge troll with blue skin, brown eyes and two spiraled horns in the head.

In his human form, he was a slender man with blonde hair and a beard.


Despite being a changeling spy, Krax demonstrated a surprising lack of tact, foresight and even intelligence. His purchasing every gaggletack from RotGut's to prevent others from using them to expose changelings easily made him suspect, and he clearly had no plan on what to do if he were confronted or even exposed, as he was caught completely off guard once he was revealed as a changeling by Blinky and Claire.

Powers & Abilities[]





  • Gaggletacks: Krax brought off the whole stash of gaggletacks to prevent anyone from revealing what he really was (which turned out to be counterproductive when Blinky and Claire discover his true nature).


Queen Usurna[]

Queen Usurna is Krax's mistress. She used him to spread rumors and deceptions within Trollmarket to have the Troll Tribunal sentence the human Trollhunter to the Deep as punishment for releasing Gunmar from the Darklands.

  • Some viewers have observed the human form of Krax bears a resemblance to Trollhunters staff writer and Wizards co-executive producer Aaron Waltke, and speculate he was the inspiration for the character model.
    • He even shows a comparison between himself and Krax's human form on his Twitter page, implying that his character design was indeed modeled after him.
