The true antagonist of Sand Land, Zeu is the aging commander of the King's forces. Due to his failing body, Zeu is confined to a floating robotic lift. He ordered the attack on the Picchi people, the creators of the water-producing machine, to both rid himself of Shiba's disobedient tank brigade and the threat to the King's monopoly. He uses the King as a figurehead to rule Sand Land. Ultimately, Are shoots and kills him with a tank cannon blast.
