Ice Common eyes
Profily is a recommended character and a contestant who allegedly competed in Battle for BFB. They resemble a default YouTube profile picture. In "The Hidden Contestant", they debuted in the game and were eliminated shortly after; their elimination was made into the episode's challenge. They claim that they have been part of BFDI since the very beginning. It is not confirmed if these claims are true, although Announcer and themselves do recognize each other in B.F.B. = Back From Beginning, as they nicknamed him "Announcery Forfouncery" and he calls them by their main nickname and does not ask who they are. This may possibly mean their claims are true.
