RC-1262, nicknamed «Scorch,» was a clone commando who served in the Galactic Republic‘s clone army as part of the elite unit Delta Squad. In 20 BBY, the squad recovered two killed Jedi from the planet Devaron following a massacre there led by Count Dooku‘s new Sith apprentice, Savage Opress. Delta Squad took the bodies to the Jedi temple on the planet Coruscant and reported to four Jedi High Council members there.

In the period following the end of the Clone Wars and the rise of the Galactic Empire in 19 BBY, Scorch was involved in the training of the first generation of non-cloned Imperial stormtroopers at an Imperial base on the planet Daro. After fellow clone commando CC-5576-39 «Gregor» was captured trying to desert the base, the rogue clone commando unit known as the «Bad Batch» infiltrated the base to free him. Scorch engaged Gregor and his liberators and pursued them, wounding Gregor and overpowering Tech before being incapacitated by a flurry of stun blasts by the remaining rogue commandos. He later regained consciousness and joined Imperial troops on an LAAT/i gunship to apprehend the Bad Batch leader, «Hunter,» taking him into Imperial custody.
