In the film, when the First Order destroys the Hosnian System with the Starkiller Base superweapon, the Resistance base on D'Qar becomes the next target. Quickly establishing a plan to destroy Starkiller Base, Nunb, along with the rest of the Starfighter Corps, flies to the planet in an attempt to destroy its thermal oscillator and disable the weapon. During the battle, many Resistance pilots are killed before the oscillator is destroyed by Poe Dameron (Oscar Isaac). Nunb is one of seven surviving X-wing pilots, and he celebrates with the rest of the Resistance upon returning to D'Qar.
