Main

• Anton Yelchin (episodes 1–41) and Emile Hirsch (episodes 42–52) as James "Jim" Lake Jr. / Trollhunter,^[1][2] the first human Trollhunter and a reluctant hero dealing with the pressures of leading a double life. He has a talent for cooking and eventually sword-fighting, and cares deeply for his mother and friends. Yelchin provided the voice of Jim from Part 1, through portions of Part 3 before his death. Hirsch assumed the role and replaced him.
• Charlie Saxton as Tobias "Toby" Domzalski,^[17] Jim's best friend and confidant. Dorky and excitable, he fully embraces the secret world of trolls and aids Jim in his quests. His weapon of choice is a warhammer.
• Lexi Medrano as Claire Maria Nuñez,^[17] Jim's best friend/girlfriend. She is a feisty, kind, jolly, sarcastic, curious, and intelligent tomboy who enjoys books and is a talented martial artist and gymnast. She obtains the Shadow Staff (Skathe-Hrün), a staff capable of creating portals activated by the user's emotions.
• Kelsey Grammer as Blinkous "Blinky" Galadrigal,^[2] Jim's six-eyed four-armed troll mentor. A wise and scholarly troll with a heart of gold, he serves as the brains of the Trollhunters and eventually becomes a sort of father figure to Jim.
• Jonathan Hyde as Waltolomew ‘Walter’ Stricklander ‘Strickler’,^[17] Jim's history teacher who is actually a Changeling. When Jim discovers the truth, in Young Atlas, he loses all respect for him and the two become bitter enemies. However, he remains affable toward Jim and has redeeming qualities.
• Fred Tatasciore as Aarghaumont "AAARRRGGHH!!!",^[17] a burly troll and close companion of Blinky, who forms a deep bond with Toby. He was kidnapped by the Gumm-Gumms as a child from the Krubera (a race of troll that lives deep in the earth) which stunted his vocabulary. Tormented by the atrocities he committed, he deserted Gunmar to live a life of peace (as shown in Wizards). However, he will still fight to protect those he cares about.
• Victor Raider-Wexler as Vendel, the leader of Trollmarket. An ancient and wizened troll, Vendel is at first suspicious of Jim and often comes across as a pessimist, but shows a softer side and eventual faith in Jim. At the end of Part 2, he is killed by Usurna after she reveals herself to be working for Gunmar, but not before recording the act to warn the Trollhunters.
• Ron Perlman as Bular,^[2] the son of Gunmar. A brutish and powerful troll warrior, he is obsessed with freeing his father from the Darklands. He holds a special disdain for Changelings, whom he considers "impure", putting him at odds with Strickler and other Changelings who seek to free Gunmar. He is killed by Jim in the first half of season 1, but later makes appearances in the season 1 episode "Where Is My Mind?" and the season 2 episode "Unbecoming".
• Clancy Brown as Gunmar, the iron-fisted leader of the Gumm-Gumms who reside in the Darklands. He is powerful and ruthless, and will readily dispose of loyal minions and allies who can no longer serve him. He has no qualms about enslaving or killing his fellow trolls to accomplish his goals. However, he cares deeply for his son, Bular. Despite his apparent main antagonist role, Gunmar in fact serves Morgana.
• Amy Landecker as Barbara Lake,^[17] Jim's protective and overworked mother. Her husband left the family when Jim was five years old. Her doctor job means she's often away from home, which lets Jim pursue his Trollhunter duties.
• Steven Yeun as Steve Palchuk,^[1] a narcissistic bully who frequently harasses Jim. Suspicious of Jim's unusual behavior, he eventually discovers the truth and teams up with Eli Pepperjack becoming the Creepslayerz to help Jim in Part 2.
• Cole Sand as Eli Pepperjack, a nerdy classmate of Jim who believes in the paranormal. In Part 2, he teams up with Steve Palchuk to investigate the strange creatures they both have seen and to help Jim.

Recurring

• Matthew Waterson as Draal, the son of previous Trollhunter, Kanjigar. He is originally jealous and suspicious of Jim but later befriends him – acting as Jim's fighting tutor. During a battle in the museum, Draal sacrifices his lower right arm while removing the Trollhunter amulet from the Killahead Bridge to close the portal, and later obtains a mechanical prosthetic. Draal explains that his father kept a distance from him as he grew up, and he had hoped to become the next Trollhunter that he might earn his father's approval. He was killed by Angor Rot in season three.
• Lauren Tom as Nomura, the Changeling museum curator and a colleague of Strickler. Originally an antagonist, she was pulled into the Darklands and imprisoned by Gunmar for her failures. When Jim is captured in the Darklands, the two form a connection and escape together.
• Jimmie Wood as NotEnrique, the Changeling swapped with Claire's baby brother Enrique. While troublesome and self-serving, he isn't actively malicious and even helps the Trollhunters from time to time (usually after being bribed). He forms a rocky but brotherly connection with Claire.
• Tom Hiddleston and James Purefoy as Kanjigar the Courageous, Draal's father and the noble Trollhunter prior to Jim. His ghost tutors Jim, often worrying about Jim's team fighting style, believing that the Trollhunter must work alone to avoid endangering those he cares about – this leads to Jim's guilt and decision to venture into the Darklands alone. Hiddleston provided the voice acting for Kanjigar during the series premiere, while Purefoy was cast to assume the role for the rest of the series.
• Ike Amadi as Angor Rot, an ancient troll assassin who hunts down Trollhunters and takes their souls. In medieval times, Angor made a deal with Morgana, surrendering his own soul in return for his mystical powers.
• Rodrigo Blaas as Gnome Chompsky, a Gnome adopted by Toby. He started out as a "rogue Gnome" causing trouble, but after he was finally defeated by Jim he became friendly when he was given a dollhouse to live in and a plastic doll to be his companion.

• Anjelica Huston as Queen Usurna, the queen of the Krubera, AAARRRGGHH!!!'s race of trolls who lives in the Deep Caverns, and a member of a council of troll leaders known as the Tribunal. She initially seems to be a kind queen concerned for AAARRRGGHH!!!'s well-being. As a Tribunal member, she is strict and judgmental and leads the Tribunal to act against Jim and his friends. Late in Part 2, she reveals herself to be a traitor who works for Gunmar and helps him take over Trollmarket.

Development

Initially, del Toro envisioned the idea as a live-action television series; however this was deemed impractical due to budgetary concerns, and as a result he instead turned the idea into a book. DreamWorks Animation optioned the book to develop as an animated feature film, to be directed by Guillermo del Toro and Rodrigo Blaas. Eventually, Netflix greenlit the project as a high-end animated series instead, eager to work with del Toro and expand their slate of original animated programming. Rodrigo Blaas became an executive producer and supervising director on the series.^[18]

Del Toro modeled the show's sensibilities after shows he grew up with such as Jonny Quest, identifying them as "really earnest and emotionally beautiful".^[19] To this end, he sought to make the main character of Jim "in that '70s mold," and "really a very good boy" with del Toro noting that this was a constant struggle for him to express.^[20] Eventually he came across Anton Yelchin, who embodied those qualities although by del Toro's estimate it still took him a few sessions to fully understand the character.^[20]

Writing

When creating the show's narrative, Guillermo del Toro do noted that he and the writers wanted a "bittersweet journey" for the main character dealing with issues that most such "power fantasies" failed to address, telling Indiewire, "... I wanted to say, 'Look, you can be in high school and you can have your problems. Then you get all these powers and then you have a different set of problems. There is not such a thing as a final, great outcome.'"^[19]

The writing team remained small and consistent throughout its entire fifty-two episode run, allowing Marc Guggenheim, The Hageman Brothers, Aaron Waltke, Chad Quandt, and A.C. Bradley to build out all three seasons in advance of the show's premiere without interruption. This provided the writers a rare opportunity for an unusual amount of intricate planning and plot serialization to be woven throughout the series, including details planted for secrets that wouldn't be revealed until seasons later, sometimes even hinting at storylines for future installments of Tales of Arcadia that wouldn't be announced until years afterward.^[21]

Cast

The show serves as one of Yelchin's final projects as he died shortly after recording most of his character's dialogue. Producer del Toro refused to replace his recordings,^[22] which del Toro noted was a challenge for the show's recording engineers.^[20] Of his decision, del Toro stated that the actor "was proud of what he did, and we were so proud of how he did it." Del Toro added that his experience as a father and Yelchin's young age were also factors that led to the decision.^[18] Some roles were written specifically for the actors who eventually portrayed them. In the earliest sketch for the series in one of del Toro's notebooks, the character of Blinky was drawn with Kelsey Grammer's name next to it, who accepted the role when the series was eventually greenlit.
