Dot Hack Avatars

Dot Hack is a multimedia franchise that encompasses four games for the PlayStation 2 console, three anime series and several manga series, as well as novels. The franchise primarily surrounds a future in which one operating system, Altimit OS, is used by nearly all computers in the world due to a computer virus named Pluto's Kiss that crashed the Internet, shut down all networked computer and communication network control systems, and sent hundreds of PC users into seizures on December 24, 2005. From that point on, Altimit OS became the only major operating system in the world, and the only OS allowed on the Internet. This is credited to its remarkable stability.

The primary focus of the franchise, however, is the popular MMORPG The World, the first network game to be allowed to run after the events of Pluto's Kiss. It was wildly popular, with over four million users signing up at its launch. The series focuses on a particular set of events known collectively as the Twilight Incident, in which multiple users were forced into a coma while playing the game. Most of the stories revolve around a group of AI, including Aura, Morganna, Aura's "child" Zefie, and various other anomalous AI.
