Avian Molina was one of the first three people to encounter Slender-man. He, along with David and Zachary, are the only characters to encounter Slender-man so far. His encounter consisted of three-four days in which he was missing, which then lead to him being found at Kieth-Weiss Park, claiming to have woken up there after Friday.
Avian is quite playful and adventurous. He is a lot more laid back than all the others.
