Yolo Ziff was a human male artist who flew for the Resistance during its conflict against the First Order. In 34 ABY, Ziff created propaganda for the Resistance, and he participated in the assault on Starkiller Base, flying under the command of Black Leader Poe Dameron. During the battle, the Resistance pilots targeted Starkiller Base's thermal oscillator, a weak point in the superweapon. Although their weapons were not strong enough to cause any damage to the structure, Ziff spotted a hole in the oscillator, which had been created by Resistance members Han Solo and Chewbacca, who were on the planet's surface. With the new opening, Ziff and the other pilots renewed their attack on the oscillator, and Dameron destroyed the target, crippling the weapon.
