James Lake, Jr. is the main protagonist of Trollhunters

Official Description

"On the surface, Jim appears to be an average 15-year-old student. He goes to school, stays out of trouble, looks after his mom, and selflessly puts others above himself. But there's a piece of him that yearn for a life of adventure outside the doldrums of suburbia. When destiny calls and a magical amulet chooses Jim to be the first human Trollhunter, the protector of a secret world of Trolls living beneath his hometown, Jim is thrust into the greatest adventure of his life. Whether it's rogue gnomes, mischievous goblins or Trolls of the worst kind, Jim has a lot to learn if he wants to live to see graduation."



Around his fifth birthday, Jim's father walked out on their family. His mother then told him that they needed to take better care of each other. Jim has cared for his mother ever since.

Part One

Finding the Amulet

Jim finds the Amulet of Daylight in the rubble of Kanjigar's body. After Blinky and AAARRRGGHH!!! find him and reveal his duty as the Trollhunter, Jim immediately goes to tell Toby. That night, Blinky gives Jim a speech encouraging him to accept his destiny as the Trollhunter.

The next day at school, Strickler causes the Trollhunter armor to activate, and Jim uses the Romeo and Juliet play auditions to attempt to hide the true nature of the armor. Forced to audition, Jim uses Blinky's speech about destiny, and winds up getting the part. Unfortunately, Stickler has also found out and is actually working for Gunmar.

First Arrival in Trollmarket

Jim and Toby are taken to the land of Trollmarket and are very intrigued by the environment and all of it's inhabitants. However, the trolls do not take kindly to the arrival of humans in their town, much less having a human as their protector, especially Draal the Deadly, Kanjigar's son. 

When Jim starts his training, Jim begins having difficulty with the dangerous and fearful tasks. Then, Draal decides to battle Jim for the honor of being the Trollhunter, which Jim has no choice to but accept. Jim tries to get rid of the amulet, but it won't leave him alone. Jim has no choice but to accept his newfly found fate. 

The Double Life Begins

For his first task as the Trollhunter, Jim is sent to stop a gnome named Chomsky, who is stealing everything in Trollmarket. Using a shrinking spell, Jim and Toby capture him. However, Jim is still shrunken on the same day that he is supposed to give his Spanish report. Jim and Toby then come up with a plan to give the report while the shrinking wears off. 

Jim decides to give his Spanish report via web cam, but runs into some trouble when Chompsky starts rampaging through Toby's house and he starts going back to his normal size. Luckily, Jim gets a passing grade and nobody becomes suspicious. Unfortunately, Jim starts neglecting rehearsals for the school play.

Discovering the Killahead Bridge

Jim and Toby go on a field trip with their class to a museum of ancient history. During that, Toby discovers that some goblins are on the loose and informs his friends about it. They arrive at Eli's house, where the goblins last attacked to stop them. Unfortunately, the goblins get away and leave with Toby's watch.

The next day, Jim and Toby find out that

Physical Appearance

Jim is a rather tall, slim young man of fifteen (later, sixteen), with blue eyes and short dark brown hair. He wears a blue zip-up jacket with the sleeves rolled up to his elbows, and a white shirt underneath. He has blue jeans and blue and white sneakers.

While using the Amulet of Daylight, Jim wears a silver suit of knight's armor, complete with breastplate, pauldrons, blue trimmings, greaves, and sabatons. Underneath the armor, he wears a sort of black undershirt, although this inner layer has never been fully shown. While wielding the Amulet of Eclipse, this armor is black with red trimmings. Both armors have their respective amulets mounted on Jim's left chest and their swords stowed on the backs of the armors.


At the start of the season, he is shown being the caretaker around the house, cooking meals for himself and his mom, Barbara Lake. Despite it being Barbara's job to take care of him, he likes taking care of her because of how much work she does as a doctor. Jim can get nervous often, as he didn't want to accept his new position of the Trollhunter, never been in a fight before, or was to nervous to ask his crush, Claire, to the dance. However, when he perseveres and tries, despite his fear, he can succeed in his job which proves how brave and hard-working he is. After getting used to being the Trollhunter, he is braver than ever that he took on Bular and the changlings. 

Jim is protective of his loved ones, to the point that he might be over-protective. To keep his loved ones safe, like his friends Toby, Claire, Blinky, and AAARRRGGHH!!!, or his mom, that he'll try to keep them out of a fight and finish it alone. Another sign of his over-protectiveness is that he's willing to lie to his mom to keep her from worrying. Jim kept it a secret, but he didn't keep it hidden because Barbara is aware of Jim's lies and kept demanding him to tell the truth, but Jim kept lying to protect her, despite it only straining their relationship even further. He's definitely willing to keep lying for his loved ones' safety no matter what the consequences are, even when they spoil his "good boy" reputation toward the people he knows like his teachers, Claire, and especially his mom. Most of all, when his mom finally found out he is the Trollhunter, she had her memory erased and she made him promise to tell her again later. Jim did promise, however, he chooses to brake his promise again so she wouldn't worry. Despite being protective, he knows when he can't accomplish things without help from his team.



After being chosen by the Amulet of Daylight, Jim is able to summon the sword Daylight and his armor by chanting "For the glory of Merlin, Daylight is mine to command!" Jim is able to manipulate the armor any way he desires, such as causing his sword to return to his hand in combat or switching hands, or summoning one of the alternate weapons provided by the armor. Sometimes, he is shown activating the amulet without speaking the incantation.

Enhanced Strength and Durability

Thanks to the Amulet of Daylight, Jim is slightly stronger and more durable than an average human. He has been seen taking hits that would have almost certainly broken an ordinary person's bones, as well as withstanding Bular's crushing grip. Jim has even withstood a high-altitude lightning strike, which was sufficient enough to kill a Stalkling and would have severely injured if not killed an ordinary human.


Jim is an accomplished cook, making meals for himself and his mother while she works. Toby Domzalski and Mr. Strickler have both praised his cooking.


After training with Draal, Jim is an accomplished swordsman, able to hold off Nomura, Strickler, and even Bular himself. Jim's fighting style is somewhat chaotic, but he uses his agility to outsmart larger and stronger foes and get behind their guard. Jim's proficiency has extended beyond Daylight as well, as he is able to parry Angor Rot's attacks with his newly discovered daggers and even hold off Nomura using a frying pan in his house.

Martial Arts

Although Jim had no formal training in martial arts, he was instructed in the art of hand-to-hand combat by Blinky and Draal. While he relies on his sword for most attacks, Jim has been shown to improvise punches and kicks in combat, and was even seen knocking out Steve Palchuk with one punch.


As the de facto leader of his Trollhunters group, Jim is usually the one who comes up with the group's strategies. Although his plans have been foiled, such as when Strickler anticipated his attempt to send Toby, Blinky, and AAARRRGGHH!!! into his office, Jim has a knack for improvising situations to complete his missions.


Amulet of Daylight

The chief weapon of Trollhunters, the Amulet of Daylight called out to Jim in the voice of Kanjigar and chose him as the first ever human Trollhunter. By chanting "For the Glory of Merlin, Daylight is mine to command!" Jim can encase himself in a medieval knight's armor, complete with the Sword of Daylight. The sword is harmful to trolls, vaporizing them on contact and blinding them with its presence. The amulet itself lets Jim translate Troll into English and vice versa, and it will return to Jim if separated, as seen when he tries to dispose of it early on and later, when it escaped the clutches of Strickler and Bular. The amulet can be opened and upgraded with special stones, including the Triumbric Stones and the Eye of Angor Rot.

Amulet of Eclipse

A new amulet that summons black armor and the black sword Eclipse. Eclipse's capabilities are currently unknown, but it can be assumed that its basic qualities are similar in nature to that of Daylight. This amulet is activated with the incantation: "For the Doom of Gunmar, Eclipse is mine to command!"


Jim's bike is his primary form of transportation in Part 1, and his main way of getting to and from school. Jim uses the bike to escape from foes including Bular and the Stalkling. After he receives a Vespa on his 16th birthday from Blinky, the bike is no longer used.

Vespa 150 G.S.

Jim's Vespa 150 G.S. was a birthday gift from Blinky and Jim's most desired birthday present. The scooter is Jim's primary form of transportation and seats 2, with Toby Domzalski and Claire Nuñez being its most common passengers.


Toby Domzalski

“Sure, I did. You had no problem sneaking into the Darklands when it was to save Claire’s brother, but now that Kanjigar says you’ve got to face Gunmar, you’re having nightmares about him and are freaking out that you’re way out of your league. I can multi-task, Jimbo! -Toby to Jim in "Mudslinging"


Toby Domzalski is Jim's best friend and "sidekick". He really loves tacos and has a crush on the school mascot (later revealed to be Darci Scott). He is always by Jim's side during battles. It is noted that Toby likes to be the only one at Jim's side. In the episode Airheads, he is seen arguing and competing with Claire Nuñez for the position of Jim's sidekick.

Claire Nuñez

"You mean WE are gonna find him... together."

-Claire to Jim in "The Battle of Two Bridges"

At first, Jim merely crushed on her from afar, until he attempted to woo her with quickly learned Spanish and she invited him to audition for the school play, Romeo and Juliet. Although he doesn't actually want to act, he auditions to get closer to Claire. However, due to his tardiness and absence from several rehearsals, their relationship begins to turn sour. After a last minute attempt to win back her trust, he agrees to babysit her little brother, Enrique, who is actually a changling, who they dubbed as NotEnrique. After causing a mess in her house, she says she never wants to talk to him again. Before he and Draal have their to-the-death rematch, he leaves her a letter, confessing all of his feelings and what has been going on with him. She forgives him, thinking it's metaphorical, but then grows suspicious and, after NotEnrique endangers her and she learns the truth, the two grow closer as she joins in on the adventures, and prepare to go to the Spring Fling together. They ultimately decide to skip the Fling, and instead dance near a cliff overlooking the city, almost kissing.


"Jim, Dance like nobody is watching, and love like its never gonna hurt..."

-Blinky, to Jim, in "The Shattered King."

He Jim's mentor and is very loyal to him. He calls him "Master Jim" and is often accompanied by his friend AAARRRGGHH!!!. Blinky helps with problems that Jim faces and looks up remedies to help him fight the rogue trolls and goblins. In later episodes, it is revealed by Walter Strickler in a fight with Jim, that Jim sees Blinky as his surrogate father.


When first entering Heartstone Trollmarket, Draal goes to Jim, demanding that he prove he's the new Trollhunter. After donning the armor, Jim grows frightened of Draal once he learns that Draal is Kanjigar's son, the last Trollhunter, and believes he himself is the amulet's rightful heir. Saying it's "training", he challenges Jim in the Hero's Forge with Vendel watching. Jim quickly loses and this causes him to question whether the amulet chose correctly. After his doubt settles and with his confidence restored, he asks Draal for a rematch. However, he grows fearful again once it's explained that a rematch would be to-the-death. In their match, Jim, using the knowledge he gained from reading A Brief Recapitulation of Troll Lore, wins the match, but ignoring the chants of the other trolls, doesn't kill Draal and instead helps him to his feet. Draal, exiled out of shame, takes refuge in Jim's basement, and vows to protect his house. He trains Jim how to fight and continues to live with Jim for the remainder of season 1, even after he is welcomed back into Heartstone Trollmarket.

Barbara Lake


“I want you to know something. Even before you found this amulet- way before all this- you were always my hero. My beautiful boy…”

-Barbara, to Jim in "A Night to Remember"

After Jim's father left them around his 5th birthday, they vowed to always take care of each other. To the present day, Jim has continued to care for his mother, doing all of the cooking and cleaning in the house. When Jim became the Trollhunter and met his new trolls friends, he was determined to keep it all a secret from her just to keep her from worrying. Unfortunately, she got worried either way. After Jim gets more involved in his occupation as a Trollhunter, his mom grows more worried, as he's begun to return home at late hours, argue, and keep secrets from her. He expresses discomfort that he must do such things, but continues to, and heatedly tells her that he doesn't want her to see Mr. Strickler again after she invited him over for dinner, even though she's fond of him. Their relationship continued to strain and only seemed to worsen until, while waiting for Angor Rot to enter his house, she comes home early. Unable to make up a lie in time, he quickly reveals the truth to her and after Mr. Stickler is injured, causing Barbara to receive the same injury due to their intertwined fates, he brings her to Trollmarket to heal her. Vendel tells him the only way for Barbara to heal properly is to unbind her from Mr. Strickler, however, she would also lose her memories in the process. Barbara begs several times for Jim to remind her of his life as a Trollhunter when she comes to and promises that he will. Once she loses consciousness, he rushes her to a hospital in the human world so she can heal properly. After she reawakens, she asks Jim what happened, he lies and tells her that she was in an accident, breaking his promise.

Eli Pepperjack

Jim and Eli don't hang out much, but they get along well. Jim will often help Eli when Steve is pushing him around or give him advice on how to act cool. Eli wants to be Jim's best friend, but Jim has yet to tell Eli of his secret life.
