Xenon or Zenon (氮) first appeared at the anime Gensoumaden Saiyuki and is one of Homura's allies in the second half of the series. In the manga, Zenon makes only a brief appearance in Saiyuki Gaiden, talking with Homura and Shien.
Like Sanzo and Gojyo, he frequently smokes cigarettes and drinks alcohol. His revolving 'Demon Blaster' destroys dozen of monsters. His right eye is covered by a black patch. It is revealed that the eyepatch is his demon limiter, after he became a demon himself for having killed 1000 demons. His full power in his true form is so great that if he stays in it too long he starts to lose all control of it. Zenon agrees to follow Homura for multiple reasons. One being he is disgusted of both life in Heaven and of living in general, another is that he wants to find the demon who killed his wife and son.
Years ago, Zenon went freely between Earth and Heaven (the year was not specified in the anime) as an assassin for the gods. He eventually married a human woman who became pregnant with his son. The other gods found out about this, and Zenon agreed to give up his immortality and just live with his family as a human, since he preferred to live on earth anyway. However, one of his subordinates (who was a youkai), was told to bring his wife (and unborn son) to Heaven, but killed them instead. He killed the demon two episodes after his first appearance, but decides to stick with Homura to the end.
Zenon came down with Prince Homura to rebel against Heaven with him, in response to them sending a demon to apprehend his wife, Mirei, and new born son, who were killed in the process.
He dies in battle against Goyjo and Hakkai towards the end of Saiyuki Gensomaden .
