"Tracker" was the nickname of a clone trooper who served in the Grand Army of the Republic during the Clone Wars. Tracker along with Threepwood and Boil accompanied the Jedi Obi-Wan Kenobi and Anakin Skywalker during a mission to hunt down the Sith fugitives Count Dooku and Quinlan Vos, who had escaped from Republic custody and crash-landed their ship, the Banshee on Christophsis. Tracker found blood at the crash site and the Jedi-Republic party deduced that the fugitives had survived but were injured. Shortly later, Republic forces launched an attack on the Separatist base on Christophsis; leading to the Second battle of Christophsis.
