Edge officially known as CT-9538 was a clone trooper in Tango Company. He fought during the Second Battle of Geonosis. He had silver hair (dyed) and a tattoo of the letter "S" on his forhead, similar to Sketch's.
After the droid factory on Geonosis was destroyed, Jedi Padawans Ahsoka Tano and Barriss Offee was ordered to to pick up medical supplies from a medical station above Ord Cestus. Edge and the rest of Tango Company should help the padawans, but when sleeping near the Progate Temple, trooper Scythe was infected by Geonosian brain worms and brought some with him on board at the medical frigate.While on the frigate, Edge and all most all the other clones where soon infected too, and Scythe first ordered Edge and fellow clone Ox to kill the pilots, who were not infected, and to attack the Jedi after. Edge and Ox failed and were knocked out. Lieutenant Trap and trooper Havoc, heard the shots, but came to late to help the others. The two clones convinced the padawans that they don't knew what happened and Havoc was left behind to stand guard over Edge and Ox. Trap went with the padawans, but after trying to kill Barriss, he himself was killed. Later both Edge, Ox and Havoc helped infecting the last clone who were not infected, and later Barriss. Ahsoka managed to kill the worms by freezing them, and thanks to her, Edge and the rest of his company were taken care of and were all right after they were treated at the center.
