Ringo was a clone trooper who served in the Grand Army of the Republic during the Clone Wars as part of the 501st Legion. While on a risky mission that was orchestrated by Jedi General Pong Krell, he and his fellow trooper Oz were killed by mines that were set by the Umbarans in the pathway. Soon after, the rest of the unit was ambushed and driven back by Umbarans, but eventually, the 501st won the fight for the planet after a long war.
