Calum Gram was a Rebel pilot who fought for the Rebellion during the Galactic Civil War, and was a male human. Gram honed his expert flying abilities as a search and rescue pilot with the Wilderness Preserve service located on Atrisia, where he would navigate an airspeeder through the thick vegetation of the planet, landing with great accuracy. During the Battle of Scarif, he was known as Blue Nine.

Calum Gram, as a member of Blue Squadron, donned a blue flight suit along with a helmet of a design that was comparable to those worn by U-wing pilots.
