The character Captain N first appeared in Nintendo Power magazine, created by a Nintendo staff member and magazine editor named Randy Studdard (who presented Nintendo with a formal proposal that included the character as a company spokes-character, the origin and premise, and the Saturday morning cartoon as part of the entire marketing campaign). The original concept involved Captain N (originally known as "Captain Nintendo") as a Nintendo employee and the Mother Brain as piece of programming from a Nintendo game pak (that was infused in an explosion with experimental "organic" ROMs) that went rogue. Captain N had the power to temporarily give life to characters and items from Nintendo games. The story left a door open for a sequel (Mother Brain is temporarily defeated but her return was said to be inevitable, and Captain N vows to stop her when the time comes). Nintendo of America, Inc. later decided to follow Studdard's ideas and create a cartoon series, opting neither to credit nor to compensate its creator. DIC Entertainment was shopped as the animation studio, and changed various aspects of the original idea while keeping the main premise of the Captain opposing Mother Brain as he interacted with a number of video game characters
At the outset of the first episode the hero of the series, Kevin Keene, a teenager from Northridge, Los Angeles, California, and his dog Duke are taken to another universe known as Videoland when they are sucked into a vortex called the Ultimate Warp Zone that formed in his television.
In order to fulfill an ancient prophecy, Kevin is destined to become the hero "Captain N: The Game Master" and save Videoland from evil forces led by Mother Brain from the floating world/fortress called Metroid. By the time Kevin arrives on the scene, Mother Brain has almost succeeded in capturing the Palace of Power and conquering all Videoland. Kevin (who in Videoland is armed with a Zapper and a belt buckle shaped like an NES controller) and Duke appear suddenly on the other side of the Ultimate Warp Zone before the N Team, which consists of Princess Lana (the acting ruler of Videoland as the first episode explains the absence of her father the King), Simon Belmont, Mega Man, and Kid Icarus.
