Jeff Andonuts (ジェフ・アンドーナッツ, Jefu Andōnattsu) is a character appearing in EarthBound, as one of Ness's friends and a party member. He is the only playable character in EarthBound to lack PSI power (making up for that with all those machines he's built).
Jeff appears as a trophy in SSBM.
Another of Ness's friends in EarthBound, Jeff is the only son of the famous scientist, Dr. Andonuts. Jeff is a mechanical genius, able to turn common, broken tools into complex weapons like the Hungry HP-sucker and the Slime Generator. He's a bit on the shy side but incredibly intelligent and brave in the heat of battle.
Game: EarthBound (06/95)
In Brawl, he appears as an Assist Trophy. Once he sets it up and nervously takes cover, he launches four bottle rockets and one big bottle rocket, all of which home in on the nearest opponent. The number of times he does this is dependent on his summoner's standing in the current match (More times if behind).
Dr. Andonuts's son, who attends a boarding school in Winters. He receives a telepathic message from Paula saying that she and Ness have been captured, and he sets out to rescue them. He's Ness's age but has the knowledge of an established scientist. He repairs broken items and makes them into other things. As his IQ increases, so does the number of things he can create.
