Blinkous Galadrigal, usually called Blinky, is the chief Troll advisor to the Trollhunters.
Grandoise in speech and with never-ending enthusiasim, Blinky is the chief Troll advisor to Jim and his friends. He views himself as a mastermind and diligent trainer, though the rest of Trollkind considers him as a crackpot for embracing Jim as the first ever human Trollhunter. Blinky sees potential in Jim even when almost no one else does, and he will do anything to help him succeed.
Blinky is a green-blue Troll with four arms, blue hair, and a set of short horns on the back of his head. He has three eyes on either side of his long orange nose, and patterns on his chin, arms, and chest. He wears brown shorts with suspenders, and a satchel.
Blinky previously trained a Trollhunter named Unkar the Unfortunate. However, Unkar died on his first night out, torn limb from limb. Also, several times in the past, Blinky has made conspiracy theories and tried to explain them to the Vendel and the other Trolls, sometimes causing a wide panic. Due to the several times his superstitions had no evidence and no result, many Trolls in Trollmarket, including Vendel, see him as unreliable and slightly paranoid.
Blinky had a brother who dabbled in the magic spells and hexes department, but Blinky lost his faith and trust in him after he turned over to the dark side, leaving Blinky with his brother's library of books.
Blinky arrives in the basement of James Lake Jr.'s house with his accomplice AAARRRGGHH!!! Jim is attracted by the noises they're making, and investigates. After switching off the light, and revealing themselves in the light of a fire, Blinky informs Jim that the significance of his possession of the Amulet of Daylight, means that he is now a Trollhunter. After Jim is knocked out, they disappear.
The next night, as Jim tells Toby about the Amulet, Blinky and AAARRRGGHH!!! burst into the house and reveal that they have been spying on him. The two trolls tell Toby and Jim more about the history of the amulet, including the dangers and eventual death. Toby talks Blinky and AAARRRGGHH!!! into delaying Jim's training for a day. Before departing, Blinky gives Jim a motivational speech about destiny, which Jim later uses in his audition for Romeo.
Blinky and AAARRRGGHH!!! encounter Jim and Toby once more as they flee from Bular, bringing the boys into Heartstone Trollmarket for the first time. They approach two trolls, Vendel and Draal, both of whom are shocked to see that the new Trollhunter is a human being. Blinky begins training Jim for his battle with Draal for the honor of being Trollmarket's new protector and teaching him the history of the magical world and how they all came to be. Unfortunately, Jim's inability to focus (due to his new double life) causes him to slack off on his studying.
Blinky is Jim's advisor as the Trollhunter and surrogate father figure. It was Blinky who encouraged him to become the brand new Trollhunter and protect the world from evil.
As Jim's best friend, Toby has many questions about Trolls, and Blinky is happy to answer them.
Blinky and AAARRRGGGHH!!! are close friends. They are rarely seen apart.
