The Spectrals inhabiting the system had virus checks in place, so Powerlock and his brother disguised themselves with a cloaking device. Powerlock took the appearance of a sprite so that he could join the Hero Selective and infiltrate their group. His brother took the appearance of a Spectral so that he could infiltrate the city's leaders.
After Matrix and AndrAIa entered the system through a Game Cube, they detected the two viruses and helped the Spectrals and Hero Selective to identify Powerlock's brother. They captured him and questioned him. The Spectral Virus wouldn't identify his brother, but they soon found out it was Powerlock. Frisket was able to tell that Powerlock was a virus, too.
They found him at the system's Principal Office, just about to overload the city's core. Powerlock shot at the ceiling and a large piece fell on Cursor. He was deleted soon after. Powerlock was deleted by Matrix, and his brother was decompiled by the Spectrals.

- Powerlock's real form is never shown on camera, but his death cries imply something monsterous.
