Kolac Pru was a male Kaminoan who functioned as an independent scientist operating within the black market.
In the Imperial Era, Pru employed the human Mahjo Reeloo as his helper, and he generated a clone of her. At this time, the Mandragonian Mob hired Pru to duplicate a specimen of the thornsuckle plant, a poisonous species thought to be extinct. The Mob's goal was to mass-manufacture the plant for use as a bioweapon. Upon Reeloo's discovery of this scheme, she tried to sabotage Pru's undertaking with a defoliator bomb. This device was set off inside Pru's starship, leading to the assumption that both he and the thornsuckle sample were destroyed.
The initial appearance of Kolac Pru was in the canon young adult novel Pirate's Price, penned by Lou Anders, with illustrations by Annie Wu, and released in 2019.
