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 he is also 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 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.

Even after all the long battles, they all were defeated by Belial, and when Belial took the Plasma Spark, all the Land of Light was frozen, along every Ultra. After Ultraman Zero defeated Belial and recovered the Plasma Spark, every Ultra went to listen to Ultraman King's speech.

- Xenon is not just based off of Zoffy, but his part was originally going to be Zoffy until Tsuburaya Productions decided to introduce a new Ultra Warrior.
- Xenon is based off the image of the Ultra Warrior named Melos who only appeared in The・Ultraman manga series.
- His voice actor, Osamu Ryutani previously voiced Ultraman Justice in Ultraman Cosmos 2: The Blue Planet.
- Just like Max, his signature Ultra Beam is fired from his left forearm instead of his right, like most Ultras. This makes him the third and final good Ultra Crusader whose signature Ultra Beam is fired from his left forearm instead of his right with the first one was Ultraman Zearth.
- His Color Timer shape has a similar shape to Ultraman Dyna's.
- Xenon's name may have been derived from a real-life noble gas of the same name.
