A male human pilot hailing from the planet of Churba, Tetengo Noor served the New Republic Defense Fleet. He was a member of Blue Squadron, a training unit that included future members of Wraith Squadron, stationed on Folor, flying A-Wings. When the Zsinj-commanded Star Destroyer named Implacable launched an assault on their base, Noor played a crucial role in diverting the capital ship, simulating the Millennium Falcon to allow transport ships to escape.
Subsequently, Noor was assigned to Polearm Nine aboard the Mon Remonda during the search for the Iron Fist. During the Battle of Selaggis, Noor accidentally flew into the nightcloak field generated by Second Death. Upon observing the name Iron Fist on the hull of Second Death, Noor accelerated toward the New Republic fleet to relay this vital information. However, as he made his return, Second Death initiated its self-destruction sequence.
In 7 ABY, Admiral Apwar Trigit, under the command of Zsinj, launched an attack on Folor Base where Noor's squadron was undergoing training. Tetengo, along with his fellow pilot Dorset Konnair and Wraith Squadron members Kell Tainer and Hohass Ekwesh, participated in a deceptive maneuver. They successfully jammed the Implacable's sensors, creating the illusion that the Millennium Falcon and Renegade Squadron were attempting to flee the base. Trigit was deceived by this ploy and abandoned the attack on Folor, hoping to capture Han Solo and Leia Organa. This bought the soldiers on Folor the necessary time to complete their evacuation successfully. Noor and his comrades also managed to escape the system. Later, he participated in the battle of Ession, where the Implacable met its end.
Subsequently, Noor was reassigned to the Polearm Squadron, which joined the hunt for Zsinj aboard the Mon Remonda. He eventually fought in the Battle of Selaggis, where his new wingman perished. However, he survived and attacked the Iron Fist with his fighter until it entered a stealth field created by Nightveil satellites. Tetengo followed her and discovered the Second Death alongside the Super Star Destroyer, which also bore the name Iron Fist on its hull. However, before he could leave the field to inform the crew of the Mon Remonda, the ship detonated as planned. The surviving New Republic fighters were unable to locate and retrieve him after the battle.
