F'ther is a devoted follower of Harm'ny Lightbeard's teachings. He is voiced by Jamieson Price. To "lighten" his name, Feather removed a few of its letters.

After it is revealed that Harm'ny Lightbeard is a hoarder and a fraud, F'ther angrily marches him to Shay to give him the spaceship part and pulls him offscreen.
