Grapa was a lieutenant in the Galactic Empire, and a human Imperial officer during the Imperial Era.
During the Galactic Empire's reign, Grapa, a human, served loyally. She rose to the rank of lieutenant as an Imperial officer, serving under the command of General Hurst Romodi. Grapa took part in the massacre of rebel sympathizers known as the Amidalans sometime between 3 ABY and 4 ABY.
Not long after the massacre, Grapa's name appeared on a list of suspected Imperial infiltrators for the criminal syndicate Crimson Dawn, which was discovered by the Sith Lord Darth Vader. Within months, Vader dispatched a group of assassins and Revengers to sent apprehend Grapa in their search for Crimson Dawn infiltrators.
The group journeyed to Tranchar in the Outer Rim Territories and demanded Grapa's surrender. Tanka, one of the Revengers, refused to leave after witnessing the Imperials torturing prisoners, insisting that the others join him. The group then engaged the Imperials, but they were unable to kill Grapa until Vader arrived to question her about the Amidalans. After Grapa confirmed the Amidalans' deaths, Tanka shot and killed her.
Grapa was a human female with light skin, green eyes, and red hair. She was clad in a standard gray uniform, complete with a belt, black boots, and a kepi.
