Gregory

Gregory is a joke character created during a now-deleted livestream. They were created when someone accidentally called Gerald "Gregory" during a game of Gartic Phone. After that, he became a running gag for the rest of the stream, and would even be added into SR 1 during the stream after many requests as a cameo, and would later become somewhat of a running gag throughout the show, appearing hidden somewhere in every episode.

Will is the main character, or "star of the show", of SR, or Sub-Space Reality. He was also the very first character created out of anyone.
