Trollhunters

Jim is the first human chosen by the Magic Amulet as the Troll Hunter—the protector of the secret troll world hidden beneath the cities of Arcadia. He is a tall, slender man with blue eyes and dark hair. Jim became a troll because of Merlin's elixir in order to defeat Gunmar. He now has gray-blue skin, blue eyes that can turn red with emotion, troll horns, pointed ears, and a half-troll height of 192 cm. Everyone has become accustomed to his appearance and no longer fears him. He cares for his loved ones and is willing to do anything for his friends. He is capable of parrying attacks and fighting with a variety of weapons, from daggers to a table knife. He wears black armor with scarlet patterns and cutouts, and a scarlet amulet. He is now taller than before, stronger, and more resilient.
Toby is Jim's best friend. He is a short, plump boy with brown hair and green eyes. He wears a red sweater over a yellow-orange shirt and brown pants. He is outgoing and has a positive outlook on life. He encourages Jim, often believing he lacks confidence. Also present are Claire, Barbara (Jim's mother), Namura, Walter Strickler, Neirinke, and other trolls. Blinky and Aark are also present.

After a few months, the people had gotten used to the trolls and were now living alongside them; no one hid or feared them anymore. Days passed, but today something was wrong. Blinky had taken something and become aggressive, and Jim immediately came running from the chaos. It took Jim a moment to realize that this enraged troll was his calm mentor, Blinky. He realized it when Blinky hurled several heavy boxes at Jim, and Jim got a closer look. Jim was already a little battered and bleeding; he tried to stop Blinky and bring him back to his senses without violence.
