Ochi of Bestoon, is an alien assassin of the Sith who operated from the time of the Galactic Civil War to approximately 35 ABY prior to the events of the Force Awakens.
During the Galactic Civil War, he was tasked by the emperor with hunting Darth Vader as a test. Afterwards, he would instead serve Darth Vader and become blinded by a massive Kyber crystal mountain on the planet Exegol.
After receiving a cybernetic visor, Ochi would become Vader’s agent in combatting the crime syndicate Crimson Dawn and attempting to retrieve the smuggler Han Solo.
Later on the orders of the Emperor, Ochi would be tasked with hunting down Rey and her parents. After succeeding in finding Rey’s parents, Ochi would murder them after they refused to give up Rey’s location.
He would later be found boasting in a cantina about Exegol, which led to him being pursued by Luke Skywalker and Lando Calrissian. This chase led him to the desert planet Passana where Ochi’s ship would crash and he would perish below the sands.
