Alex

Alex Kralie is a character in MarbleHornets, originally as the secondary protagonist, before transitioning into the role of the main antagonist. Alex appears in almost all of the entries up to Entry #20, when the series began to focus on Jay and his investigation. He makes appearances in most entries between #35 and #52, and has appeared occasionally since Entry #52.

Alex was apparently listed as publicly missing by March 2009, roughly two months before MarbleHornets actually begins, and appears on a poster in a gas station. This was seen in Always Watching.

He first comes into contact with the Operator while filming Marble Hornets. This makes him very paranoid and he begins to film himself at almost all times, even while he is sleeping. The tapes begin exhibiting strange occurrences including Operator sightings and irritable behavior from Alex which Jay says he has never seen before. Jay suspects he has been messing with the audio in the tapes.
