Biography
After the elite team of clone troopers led by Obi-Wan Kenobi and Anakin Skywalker arrived at the Citadel, rescuing the Jedi master, they split up into two teams. The team lead by Obi-Wan Kenobi began sneaking through the Citadel's ventilation shafts when Clone Commander Cody noticed this droid and alerted the rest of the squad. The droid tried to escape by flying up the shaft but Even Piell managed to catch up to it and cut it in half with his lightsaber.
