Homestuck is an illustrated text-based adventure, which is often animated and sometimes made into music. It is a story about the end of the world, and the events taking place before, after and outside this critical event.
Main antagonist so far has proven to be Jack Noir, a rogue bureaucrat turned mass murderer. Through magical, nay, scientifically-accurate means, he has accumulated unlimited power... but his temper is still rotten.
This video shows his rise to power. A collection of video's and takes featuring this be-hated grinch.
Events featured span the entire run of the comic so far: 13 April 2009 to 22 Januari 2011.
Any mistakes or lousy transitions in his depiction are solely to blame on me. That is why I am currently hiding out in a little pocket dimension south of Oz. This guy sure can hold a mean grudge.
