List of Marble Hornets Characters

Jay Merrick
=== The main protagonist of the series, who runs the MarbleHornets YouTube channel. As he is the one filming most videos uploaded to the channel, he is rarely seen on camera. He and Alex Kralie were once friends who worked on Alex's student film together, but the two fell out of contact after production on the film was cancelled. Jay later began uploading Alex's taped footage to the internet, setting off a chain of events that resulted in him becoming a target of the Operator. ===

Alex Kralie
=== Approximately three years before the series began, Alex attempted to direct a student film titled "Marble Hornets". During his time on the set, Alex began encountering the Operator and his mental state began to deteriorate, with him beginning to act rudely toward his actors and assistants over time. Alex later handed the production footage he had filmed over to Jay, although he had initially wished to burn it. Sometime later, he and Jay fell out of contact. ===

Tim Wright
An acquaintance of Alex who worked on his student film as an actor. Tim was later interviewed by Jay, who had also helped with the movie's production. He is known to have a history of medical conditions. It is revealed that Tim is actually masky, an individual known to have attacked Jay many times.

Jessica
A mysterious girl who Jay encountered at a hotel. He later learned that she was suffering from amnesia, much like himself. When Jay reviewed the tapes he had filmed over the previous seven months, he learned that the two had met before and that she had once been the roommate of Amy, Alex's girlfriend.

Brian was one of the main actors in Alex's student film. Jay first encountered the masked man in what he believed to be a burned down hospital and then chased him into a maintenance tunnel but then stopped due to the darkness of the tunnel.
