Ninten (ニンテン) is a character found in the Famicom classic Mother. His name is a shortened version of Nintendo. He was the protagonist of the game who set off on a journey after two of his household appliances came to life and attacked him, including a doll and a lamp. He goes off to journey to find out why exactly this had happened to him.
On his journey, Ninten will meet up with multiple other strange characters who'll ultimately be valuable team members. These include Lloyd, Ana, Teddy, and other characters who'll just briefly join his team.
Ness, an arguably more well known character from the sequel EarthBound (which, unlike Mother, was released in America), is considered to be based off of Ninten, having almost identical personalities and appearances.
