Lore & Background

Mooncake's origins are not detailed in the source, but the series establishes it as an immensely powerful alien that Gary Goodspeed befriends after discovering it aboard the prison spacecraft Galaxy One.

Throughout the series, Mooncake accompanies Gary and a growing crew of shipmates—including the artificial intelligence HUE, Avocato, Little Cato, and others—on intergalactic adventures to uncover the secrets of Final Space, a bizarre realm where the universe ends.
