A clone trooper found himself serving aboard the Tranquility, a Venator-class Star Destroyer, circa 21 BBY in the midst of the Clone Wars. The Tranquility's mission involved transporting Nute Gunray, a Separatist figurehead taken into custody on the world of Rodia, to Coruscant. En route, battle droids launched an assault on the vessel, gaining entry to the Tranquility through boarding ships. This particular trooper, along with his clone captain, received orders to safeguard the reactor compartment, but they observed no disturbances. Before proceeding to the prison deck, the pair instructed WED-15 Treadwell droid 327-T to maintain vigilance.
This trooper's debut occurred in "Cloak of Darkness," specifically episode nine of The Clone Wars television series' first season.
