Ultraman Xenon (ウルトラマンゼノン Urutoraman?) is Ultraman Max's superior. He arrived to help Ultraman Max when he was in danger and is also the one that gives Ultraman Max the Max Galaxy. He appears in episodes 13 and 39.
As Ultraman Max was about to be killed by Zetton, Ultraman Xenon, Max's superior from M78, appeared in a red fire ball like Max did when he came to Earth. Xenon held Zetton off and even used the Xenon Ray 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 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 Basark and the two went back to M78.
