Ninten (Japanese: ニンテン Ninten) is the main character and the hero of the first game in the Mother series. He lives in the town of Mother's Day with his mother and twin sisters. Ninten is a adventurous young man who travels around the world to stop a dark alien from using his fleet and destroying the planet. He also appeared in Captain Rainbow 2 as the second playable character. He comes to Mimin Island to become a hero again.
Ninten is the only Mother PSI user party member who can't use offensive PSI. As such, in his appearance in the Super Smash Bros. series, he uses support PSI for his specials, such as PSI Hypnosis and PSI Shield. His signature PSI technique is 4th-D Slip, which no other character can use.
He also appears in the Kingdom Smash Bros. series, a crossover series between Super Smash Bros and Kingdom Hearts.
- Ninten's name comes from the name of the company who created him, Nintendo.
- Ninten is the only Mother character to suffer from asthma, though this usually only affects him when he's around exhaust fumes.
