Mahjo Reeloo was a self-described scoundrel, a female human. She was initially one of two clones made to work for the renegade Kaminoan scientist Kolac Pru; however, she later regretted this and departed, while the other clone stayed behind to aid Pru even after she left. After discovering that the Mandragonian Mob had contracted Pru to duplicate a specimen of the lethal thornsuckle plant, she pledged to thwart him and eliminate it. She acquired a defoliator bomb on the black market and employed the smugglers Han Solo and Chewbacca to transport her to the Undervaults of Gwongdeen, feigning an intention to steal from one of the safety deposit boxes. Aided by Solo, Chewbacca, and the pirate Hondo Ohnaka, Reeloo successfully delivered the defoliator bomb to the Undervaults, only to find that Pru had already gathered the plant. In order to reach Pru, she engaged and overcame her clone in combat. Masquerading as the clone, she boarded Pru's starship with the bomb, which then detonated, eradicating the plant and apparently herself. Despite this, she lived, and subsequently reached out to Ohnaka, assisting him in recovering the Millennium Falcon from Bazine Netal, ultimately returning it to Batuu.
