Jeff Andonuts

Jeff Andonuts (ジェフ・アンドーナッツ, Jefu Andōnattsu?) is from the Snow Wood Boarding School in Winters. His traits are those of a stereotypical nerd or whiz kid; he wears glasses and lacks physical ability, but is great with mechanics. Jeff wears glasses to correct his myopia. He wakes up in the middle of the night at a point receiving a telepathic message from Paula informing him that she and Ness need help. At that time, Ness and Paula were taken under captivity by zombies during their investigation of the undead-infested town Threed. Jeff breaks out of his dormitory with help from his friend Tony. Dr. Andonuts, his dad, lets Jeff use a machine called the Sky Runner (called Sky Walker in the Japanese version of the game) in order to travel the distance to reach Ness and save them from their imprisonment. Once he joins them, he becomes the third member of the party. Jeff is the only member of the four that cannot use PSI power, but he can repair broken items, making them into useful weapons and items.

In Super Smash Bros. Melee, he's a trophy, in Super Smash Bros. Brawl, he's an Assist, when summoned, he sets up his bottle rocket, cowars in fright, and it goes off blasting rockets at characters.
