Megabyte is the main bad guy in the TV show Reboot. A big, bluish-purple, metal-skinned, tyrannical computer virus with detachable legs, retractable claws, the voice talents of Tony Jay, and serious attitude. His forces include his bungling henchmen, Hack and Slash, a team of slightly goofy black ops agents, and a smallish army.
Megabyte's main goals seem to be taking over the Supercomputer, or failing that, the system of Mainframe. He is the arch rival of Guardian 452, Bob. His sister, Hexadecimal, also has a habit of getting in his non-existant hair.
