Megabyte is a Class 4 virus and he likes to have total control over everyone and everything. He owns one third of Mainframe and his goal is to infect the entire system.

He lives in Silicon Tor, which is in the G Prime sector.

His sister, Hexadecimal, is also a resident in Mainframe, and is always causing problems for all the inhabitants of Mainframe, including Megabyte.

When the Web invaded, Megabyte had to work with Bob and Dot Matrix to rid Mainframe of the Web creatures, who had entered the system through the portal that the web creature from "Trust No One" had made.

Just before Mouse closed the portal to the Web, Megabyte threw Bob into a one man pod and shot him into the Web.

When Enzo lost the game, and after Hexadecimal distroyed his Tor , Megabyte seized that opportunity to take over the Principal Office and effectivly take over Mainframe. There was only a small number of 'Rebels' that fought against him and they didn't seem to worry him too much. He was to well guarded to worry about them.

When Matrix, Bob, AndrAIa, Frisket, and the crew of the Saucy Mare returned to Mainframe, it meant that the system was back on the Net and Megabyte could leave Mainframe to go to the Super Computer. Only one thing stopped him, Matrix.

Matrix was seeking revenge against Megabyte for all the things that Megabyte had ever did to him, his family, and his home. He knocked Megabyte around pretty badly. *g* Just as Matrix had won the battle, Megabyte opened a portal to the Super Computer and was about to enter it, when Mouse changed the portal so it went to the Web instead. A Web creature pulled him in the portal and it closed behind him. That's the last of Megabyte, or is it?
