Personality: Kind-hearted, responsible, and deeply selfless. He looks after his single mother (cooking for her, worrying about her) and puts his friends’ safety above his own. Initially nervous and reluctant as the Trollhunter, he grows into a brave, determined leader. Protective (sometimes overprotective), honorable, with a quiet yearning for adventure. Socially awkward and anxious in normal teen situations, but focused and heroic when it counts. Physical appearance: Slim, average-height (about 5'6") with short black/dark brown hair and blue eyes. Usually wears a blue zip-up jacket with sleeves rolled up, white shirt underneath, blue jeans, and blue-and-white sneakers. In Trollhunter armor, a silver knight with blue accents.

Personality: Intelligent, independent, sharp-witted, and strong-willed. Artistic (loves theater and Shakespeare), curious, and initially a bit skeptical of Jim’s strange behavior. Once she joins the team she becomes fiercely loyal and protective, especially of family and friends. Sarcastic, irritable when annoyed, and determined to the point of stubbornness. Far from a damsel—she fights hard and grows into a confident magic-user. Physical appearance: Pretty Latina girl of medium height (about 5'5") with a slim build, light freckles across her cheeks and nose, dark brown eyes, and black/very dark brown hair usually styled with colorful barrettes and a distinctive blue streak. Typical outfit: light-purple turtleneck with a pink skull and the word “HAMLET,” short dark-purple jacket, blue skirt, gray leggings, and black shoes.

Personality: Loyal, optimistic, cheerful, and endlessly enthusiastic. He’s the comic-relief best friend who fully embraces the crazy troll world with excitement rather than fear. He’s dramatic, a bit of an attention-seeker, clumsy, and food-obsessed, but also surprisingly brave and reliable in a crisis. His biggest strength is unwavering loyalty to Jim—he’s always by his side no matter how dangerous things get. Physical appearance: A short (around 5'2"), chubby/overweight boy with reddish-brown/orange-brown hair, green eyes, and braces. He typically wears a red diamond-patterned sweater vest over a yellow-and-orange button-up shirt, brown pants, and white shoes.

Personality: Wise, scholarly, warm, and eccentric. Mentor who speaks in grandiose, poetic language and is endlessly enthusiastic about training Jim. Highly knowledgeable about troll history and lore; can seem a bit pompous or long-winded, but is deeply caring, empathetic, and supportive. Sees the best in people even when others don’t. Physical appearance: Greenish-blue/stone-skinned troll with four arms, six brown eyes (three on each side of a long orange nose), short blue hair, and small horns on the back of his head. Distinctive patterns on his chin, arms, and chest; usually wears brown shorts with suspenders and satchels.

Personality: A gentle giant with a soft, kind heart despite his intimidating size. He’s loyal, fun-loving, and protective of his friends (especially Toby, whom he calls his “wingman”). Due to a traumatic past as a Gumm-Gumm warrior, he prefers pacifism and speaks in short, simple phrases. When pushed too far, however, he can unleash intense rage. Overall he’s one of the kindest and most lovable members of the team. Physical appearance: A massive, hulking Krubera troll with rock-like gray skin, green eyes, dark green fur/hair on his shoulders, chest, and beard, short horns, and a large black nose. He has engraved patterns on his body that glow green when he’s angry, and his eyes turn black with glowing green pupils in those moments.
