This Mandalorian Basilisk War Droid was an rogue war droid that survived the Great Mandalorian War. It found refuge working for the Black Sun during the Great Jedi Purge and would later become under the command of Mandalorian Chop'aa Notimo during the Black Sun's Assault on Cloud City. This droid and Chop'aa's sidekick, the gungan bounty hunter Kleef, captured the Imperial senator Gram Bel Iblis and crippled Cloud City's defense system. However, after the death of Kleef at the hands of Darth Vader's secret apprentice, Starkiller, Chop'aa had his droid attack the ex-sith and even battle the powerful force user himself.
Unfortuanly for them, the sith over powered both of them and won the duel, stabbing Chop'aa and crushing the droid. After this, Starkiller saved the senator and went on to later create the Alliance to restore the Republic.
