Ness is a startable playable character of Ultra Smash Bros. IV and the protagonist of his own series EarthBound (Mother in japanese). He makes his fifth appearance in the series. Ness is been confirmed at the E3 trailer with the Original 8, including Luigi, Captain Falcon and Jigglypuff.
Ness' voice is recorded once again by Makiko Omoto, who also she records Kirby's voiceclips.
On the tier list, Ness makes a great improvement to the 7th place of the 103th after Lucas, his semi-clone, for his better falling speed and his back air attack that makes a direct hit instead of lag. He's the last character of the S-tier.
- It was confirmed that Ness includes Ninten's alternate costume.
