THEWICKEDSEVEN appears to be a group with seven members, all taking part in a contest of some sort. There are two teams, Plague's Team , consisting of Plague, Puppeteer and Monis (Blacky was previously a member) and He's Team consisting of He, The King in Yellow and Angel. They all seem to refer to The Slenderman as "Father."
They, like most proxies, are bad at hiding when they post things to the youtube channel. At this point, every video uploaded by them has had strange capitalization in the title, breaking the usually non-capitalized titles that Simon uses.
