Ultraman Xenon (ウルトラマンゼノン Urutoraman Zenon), also known as Ultraman Zenon, is Ultraman Max's superior. He arrived to help Ultraman Max when he was in danger and the one who gives Ultraman Max the Max Galaxy.
As Ultraman Max was about to be killed by Zetton, Ultraman Xenon, Max's superior from Nebula M78, appeared in a red giant ball like Max did when he came to Earth. Xenon held Zetton off and even used the Xenonium Cannon to keep him at bay, but it was blocked by Zetton's Zetton Shutter. Ultraman Xenon then summoned a new weapon from the sky to use against Zetton, but he was attacked by Zetton and the weapon attaches itself to Max's right wrist. Ultraman Max then uses the new weapon known as the Max Galaxy to destroy Zetton. Xenon told Max that Zetton was one of the five monsters Alien Zetton was using to conquer Earth and would have to deal with four more. Xenon flew back to M78, trusting Max with his assignment.
Xenon returned later in Earth's orbit once Max destroyed Giga Berserke and they went back to M78.
