Wendell was originally part of a supercomputer (called WNDL) as part of the security system in a huge robot factory complex. When he became sentient, he spent most of the time trapped inside the computer, unable to communicate. After years of planning his escape, he terrorized the workers and took the factory for himself.
Sly, leader of a space exploration program, discovered him after the ship crashed near their headquarters. Wendell was transfered to a more mobile robot body, but the factory remains, its mazelike interior filled with rogue machines.
