Samus too. She's in the Comics, when Simon and MegaMan are not.
Plus, Lana was inspired by Palutena's design, so... you got a good chunk. Besides some of the characters from other games showing up in roles.
You'll have to give me a bit again. It's pretty much a case of where it was made and then immediately taken over by Nintendo from the original creator. That's how they basically own it, since they commandeered the rights due to owning the magazine it was based upon.
"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.

There's legitimately no other data on it, to be fair. Just that Nintendo pretty much created the character and took it with them due to it being made in-house, essentially. But yeah, that's fair. It seems like they do own him, just don't want to use him. Captain N was not popular at all, so why even mention him if you don't have to? It's kind of like the CD-i games to them, if you will, except not nearly as bad.
