Checkers was a clone trooper who fought for the Grand Army of the Republic throughout the Clone Wars. Early in his service, he was part of Laser Company under the command of Jedi General Kit Fisto. However, after the unit suffered heavy losses and was depleted at Kessel, Checkers was the sole clone survivor. Given the chance to transfer, and despite holding no resentment toward Fisto, Checkers asked to join Torrent Company. While serving there, he participated in a battle on Kothlis under the leadership of both Clone Captain Rex and Jedi Commander Ahsoka Tano.
