-->This is Cirron, my home. One of six planets in the Migar Federation. There was a prison break. Two hundred eighteen of the most violent fugitives have disappeared into the city of Chicago. Finding them won't be easy. They aren't human. Fortunately for Earth, neither am I.
-->'''--Cole''', ''Tracker'' opening narration.

A syndicated sci-fi series that aired during the 2000–01 U.S. TV season. ''Tracker'' centered on an extraterrestrial bounty hunter named Daggon, known as Cole on Earth, who was sent to find and capture 218 alien fugitives hiding in human bodies in the city of Chicago. He is found soon after his arrival by Mel Porter, owner of a Chicago bar called the Watchfire, and she quickly begins aiding Cole in his quest. Over the course of the series, they form a close friendship and discover secrets about Mel and her family. Other characters include Cole's nemesis, Zin; Mel's on-again off-again boyfriend, Detective Vic Bruno, and Mel's best friend, Jess.

This spelling is a fan consensus[[/note]] It was the subject of Vardian and Cirronian legends about how it was made during an ancient war and then stolen by the Migar council and hidden on Earth to keep it away from the Vardians. By the modern era, most of their peoples believed it was simply a myth. Cole and Mel obviously proved them wrong.

In one episode, Cole uses this to fake Mel's ex-boyfriend's death (by first taking his form) when a mobster tries to shoot him in the back of the head. He enters hyperspeed at the moment of the gunshot, moves his head, waits for the bullet to slowly pass, puts the head back to where it was, and resumes normal speed. He then falls off the pier to complete the illusion.
** In another episode, Zin's people manage to develop a device that allows anyone to do the same. In fact, the device (in the form of a small orb) is better, as it takes only minutes to recharge, while Cole needs a whole day.
