Jim Lake Jr.

"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 yearns 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."

James "Jim" Lake, Jr. is one of the main stars in the Tales of Arcadia franchise, serving as the main protagonist of Trollhunters (and its upcoming film, Rise of the Titans), a major character of Wizards, and a minor character of 3Below.

He is the first human (briefly half-troll) Trollhunter (and the very last in general following the Amulet of Daylight's destruction), presumably implied to be the next potential wielder of Excalibur, a former student of Arcadia Oaks High, the leader of Team Trollhunters, co-leader of the Guardians of Arcadia (alongside Douxie), the mentee of Blinky Galadrigal, best friends with Toby Domzalski, the son of Barbara and James Lake Sr., and the current boyfriend of Claire Nuñez.

In his human form, Jim is about 5 foot 6 inches tall with a slim build. By his own admission and Krel, he has skinny legs. He has blue eyes and short dark hair. After regaining his human form at the end of Wizards, Jim now has two scars on his face (one on his left cheek and one over his right eyebrow, which was the result of AAARRRGGHH!!! trying to subdue him while in his corrupted beast form).

Unarmored, Jim 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's armor is a silver suit of knight's armor, complete with a breastplate (the chest area), pauldrons (the shoulder areas), vambraces (the forearm areas), gauntlets (the hand areas), cuisses (the thigh areas), poleyns (the knee areas), greaves (the leg areas), and sabatons (the feet areas) with blue trimmings. Underneath the armor, there is a black inner layer. While wielding the Eclipse Blade, this armor is black with red trimmings. Both armors have their respective amulets mounted on the left side of the breastplates and occasionally their swords (Daylight and Eclipse) stowed on the backs of the armors.
