Ringo, a clone trooper within the ranks of the 501st Legion, fought for the Grand Army of the Republic throughout the Clone Wars. In the course of the Battle of Umbara, Ringo took part in a dangerous offensive led by Jedi General Pong Krell. While the troop moved along a central road, Ringo, alongside trooper Oz, met his death due to mines planted by the Umbarans who were the opposing force. Not long after this, the remaining members of the unit were caught in an ambush and forced into retreat by the Umbarans. Ultimately, after a prolonged struggle, the 501st emerged victorious in the battle for the planet.
