Blinky is a major character in the Tales of Arcadia franchise. He is a trainer of Trollhunters.
When he discovered that there is a teenager, Jim Lake Jr. who got a Trollhunter amulet and got chosen, he and AAARRRGGHH!!! met him and trained him as the next Trollhunter, since the previous one, who is a troll died. Blinky later brought Jim to the Troll Market in order to train him in the training ground.
He is a troll with blue skin, six eyes and four arms, which makes him very different from other trolls. He also appeared to have fangs and horns, which are typical for trolls.
He is a friendly type, since he is very nice to Jim. He is also wise, since he knows what it is like to be a Trollhunter, which is why he is a Trollhunter mentor. He also reads lots of books, which is why he had a library.
