A dramatic story set in contemporary Japan, about a guy with amnesia, who finds out he was turned into a super-cyborg in a corporate weapon research program. He goes on a mission of revenge. A little shallow, perhaps, but a good example of shounen SF/action manga. The manga ended abruptly, because the magazine it was being serialized in changed its target public and it was decided that Xenon didn't fit in anymore.
Juuki Kouhei Xenon was published in English as Xenon : Heavy Metal Warrior by VIZ Media from 1992 to 1993, with a reissue of all four volumes in 2002. Before this, it had been published biweekly in comic book format by Eclipse Comics together with VIZ comics, with a total of 23 issues published between December 1987 and November 1988.
