Lama Su was a Kaminoan male statesman who led the Ruling Council of Kamino—an extragalactic planet—during the last years of the Galactic Republic. His government was responsible for growing the clone troopers that formed the Grand Army of the Republic in the Clone Wars. Lama Su worked with the Jedi Generals who commanded the clone army during the galaxy-wide conflict with the Confederacy of Independent Systems, although he was also in league with the Sith Lords who conspired to destroy the Jedi Order through Order 66.

Prior to the Clone Wars, the Kaminoan government led by Prime Minister Lama Su was commissioned by Jedi Master Sifo-Dyas to create a clonearmy for the Galactic Republic. Sifo-Dyas was killed soon afterwards by members of the Pyke Syndicate, and Lama Su found himself in league with the Sith Lord Darth Tyranus. From Tyranus, he received a genetictemplate for the clones: a bounty hunter named Jango Fett. He was also given an inhibitor chip that was to be implanted within each clone trooper as a safeguard against betrayal from rogue Jedi. However, the inhibitor chips were designed by the Sith, who programmed the clones to exterminate the Jedi under Order 66.
