Swayzak

Swayzak is a malicious virus and the main villain of Trapped in Hyperspace, as well as the tie-in game of the same name. During the Total Immersion Event, TOM and Sara sent the into hyperspace, leaving Swayzak with the perfect opportunity to wreak havoc.

He disconnected Sara from her systems and took control of the ship in an attempt to make it crash into Earth. However, TOM didn't give up that easily and kept transmitting into the Absolution's system to try and get rid of Swayzak. TOM, with help from many others, finally succeeded and Swayzak was gone, and Sara returned alive and well. However, Swayzak secretly infected TOM, leading the others that helped TOM to help Sara enter TOM's brain and fight Swayzak in his last stand. Afterwards, Swayzak broke down in anger and swore revenge. Which has never been fulfilled.

Swayzak also made a cameo appearance in Sara 2's game review of Rez, used to describe the plot to Rez.

The voice actor of Swayzak, as well as the voice actor of Sara 2, is unknown; and will likely remain that way, according to Toonami co-creator Jason DeMarco. It is known that Jason DeMarco actually dislikes Swayzak, even though he came up with him. Despite this, it's been hinted that Swayzak might show up on the revived block in a future TIE.

Trivia

 * In the game, Swayzak had a New Zealander accent. The voice actor of him there is unknown too, all is known about him is that he was voiced by a New Zealander in his late 20s who had poor manners.
 * In the Rez review, Swayzak had a different voice (way more high-pitched, more British and unlike the voice he had in the TIE or the game.)
 * The main character of Rez has gotten the nickname "Swayzak" since the review.
