«Crys» was the nickname of a clone trooper who served in the Grand Army of the Republic during the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems. Crys served in the 212th Attack Battalion under Clone Commander CC-2224 «Cody» and Jedi General Obi-Wan Kenobi. During the Battle of Saleucami, Crys helped General Kenobi hunt down the Separatist General Grievous on the planet Saleucami. Crys’ robolobotomy skills were put to use by Kenobi in the hunt for Grievous as they dismantled a battle droid in order to gain intelligence on Grievous’ whereabouts.
