"Hoodie" is the fan-given nickname of a character in MarbleHornets, first appearing in Entry #41. Not much is known about him/her. Hoodie has been seen in a several entries, the first time in Entry #39 where he first appears, stalking Jay while he sleeps in his car. In Entry #61, Hoodie is confirmed to be at least one of the people posting to the Totheark account.
In Entry #83, Hoodie fell, potentially to his death. Entry #84 confirmed the identity of Hoodie as Brian. During the entry, an audition is shown which depicts Brian wearing the same outfit as Hoodie. Tim later confirms this fact.
Connections and Motives:
Hoodie's connections and intentions are not yet known or clear, although it is known that he was trying to kill Alex.
It is also debated that the figure leaning against a tree in Entry #40 and Totheark's YouTube admission, "Intermission" is Hoodie. Sharing the same distraught face, the text in Intermission states "Did you see me?", then displaying the figure at the tree. If one looks close enough, they can see a figure leaning against a tree in several other entries.
It is shown in entry #73 that Hoodie regularly consumes pills, since he has several empty containers of them in his living space. The fact that he has stolen pills from both Alex and Tim supports the theory that Hoodie is suffering similar symptoms as those experienced by Tim.
It is important to note that since the MarbleHornets crew has stated they do not use any parts of the myths that have arisen since the creation of the series; they do not use the term proxy. Therefore, Hoodie is not a proxy. Hoodie also does not suffer Slender Sickness.
