Mark T. Gussiberg (Earth-Gravildus-Batorok)

Mark T. Gussiberg is a Windows 1339 computer virus that absorbed the memories and personality of well-known Earth-Gravildus-Batorok scientist Mark T. Gussiberg, even murdering his wife, Nurse Poptarts, and taking over Gussiberg Tech. He enjoyed creating evil viruses patterned after real people, such as Foury Frit, who was trapped in Windows 1339 for months. After discovering he was just a virus and not really Mark, he suffered an identity crisis and tried to replace everyone with viruses. However, he was eventually redeemed by Foury, due to the compassion she came to have for him. Currently, he resides in Windows 1339, eager to make it a happy place for himself.
