His first appearance is at the beginning of the series where it is shown that he is the main character for Marble Hornets, but is constantly annoyed and confused by Alex's attitude. When the tapes that Jay got from Alex, it was unclear as to where Brian was or what happened to him. In Entry #51, Brian innocently wanders about and gets several thought-provoking shots of himself wandering a burned-down building that Alex plans to claim is Brian's old school. During the shooting, Brian gets very uneasy and asks Alex to hurry up, only to be assaulted by The Operator shortly afterward. When the camera turns back on, Brian runs all over the building for Alex and stumbles across Tim who is coughing in the corner of a burned room. When Brian turns, The Operator is behind him and the video cuts again. When the video comes back, Brian is dragged off-screen by an unknown figure believed to be Alex, while another figure (or possibly the same) picks up the camera and leaves him behind. Entry #54 features Brian once again. However, considering the fact that he was fine in the tape (as is Tim), this tape must come before Entry #51. Here he waits with Alex in Tim's apartment while Tim goes off to turn the power back on. He is at the apartment to discuss what the movie trailer's music should be. He attempts to shoot a scene, and talks with Alex and Tim about a potential shooting spot in Entry #55. In Entry #83, Tim attacks Hoodie, causing him to fall from a windowsill, seemingly killing him. Tim collects a tape from his pocket, which is shown, during Entry #84, to be the footage of Alex's auditions for Marble Hornets before he encountered The Operator. Brian is shown to be wearing the same hoodie during the auditions as Hoodie always wore, leading Tim to believe they were one and the same. This theory was later proven to be true in Entry #86, which also confirmed that Hoodie was indeed killed by the fall. In an interview for Marble Hornets, Troy Wagner, Joseph DeLage, and Tim Sutton confirmed Brian to be Hoodie. Additionally, Hoodie and Masky are the alternate personalities of Brian Thomas and Tim Wright.
