Ness is a protagonist in Super Smash Bros. Crossover. He has psychic powers known as PSI. He was a minor character in Seasons 1-3. Ness became a main character in Season 4 like the other minor characters. In Season 5, after Naruto, Sonic, and Drago leave the Institute, Ness tries to find them with Goku and Kirby. Eventually, they learn Naruto, Sonic, and Drago are on Neathia and head to Bayview to get to the portal. Upon arrival, Ness, Kirby, and Goku battle against Cyborg Helios, who arrived after pinpointing Naruto, Sonic, and Drago. Suprisingly, the trio are able to hold their ground, mainly because they caught Helios off guard. Once Naruto, Sonic, and Drago arrive, they beat Helios for the first time. Afterwards, Ness, Goku, and Kirby stay on Neathia to help Naruto, Sonic and Drago train since they won't leave. They return to Earth to help their friends after hearing their fate, and manage to defeat Dark Marth once and for all, saving their friends and ultimately liberating Marth of the silly Melee universe from Dark Marth's grasp.
