Captain N: The Game Master

From Wikitroid, the Metroid wiki

Captain N: The Game Master is a TV show from the late 80s and early 90s, where a teenage boy is named Kevin Keene transported into Videoland, a universe based around Videogames.

It featured Mother Brain as the chief antagonist operating out of a fortified asteroid referred to as Metroid.

In the Captain N comicbook series (part of the Nintendo Comics System series)), Samus Aran played a large role as a member of the N-team and a rival for Kevin Keene's affection. Her portrayal, appearance, and background story remains fairly accurate to the current image of Samus. Kraid and Ridley also makea few brief appearances, based on their concept art from Metroid. The series is significant for the first appearance of one of Samus's Gunships. While much larger, it beared the name "Hunter IV". The name "Hunter" was picked up again for the Gunship in Metroid Prime, over a decade later.

The events of the Captain N series are generally not regarded as canon, and are more of a "What if?" story.
