Giga Freeze

History
The Giga Freeze was a hindrance program designed to freeze Alpha in the event the Guardian was destroyed. It was designed by Dr.Urakawa. He was there when they blamed Bass for causing all the devices connected to Alpha to malfunction. One danger of using it was that if it was misused, it could freeze the Net forever. So they hid it in the Undernet, under the protection of Serenade, Mamoru's NetNavi. So, only the Navis who pass the Undernet Rankings could gain access to the Giga Freeze, which Serenade called "The Forbidden Program."
