Jeff's clay model from EarthBound
Jeff Andonuts (ジェフ・アンドーナッツ, Jefu Andōnattsu) is one of the lead characters in the SNES game EarthBound. He is the son of Dr. Andonuts, a world renowned scientist. At the outset of the game, Jeff is attending the Snow Wood Boarding School in Winters. Jeff is often shown as a genius boy able to repair various broken stuff found throughout the game.
After Ness and Paula are captured by zombies in Threed, Paula contacts Jeff via telepathy. Jeff leaves the boarding school. Along the way he teams up with the Bubble Monkey, a bubble gum-loving monkey. At the lake in Winters, the Bubble Monkey contacts Tessie, a large Loch Ness Monster-esque monster living in the lake. With Tessie's help, they cross the lake. On the other side, Jeff meets Brick Road, a man who aspires to be a Dungeon Man. After making his way through Brick Road's dungeon, Jeff meets with his father, whom he hasn't seen in ten years. Dr. Andonuts allows his son to use the Sky Runner ("Sky Walker" in Mother 2, the Japanese version), a small vehicle resembling an UFO. Jeff crashes into Threed cemetery and rescues Ness and Paula, then proceeds to follow the party in its quest to save the world from Giygas.
Even though Jeff's offensive stats aren't very high, aside from being unable to perform PSI moves, Jeff can create items from broken machines as well as use items that other characters cannot. His primary weapons are guns, and items exclusive to him include a bazooka, bottle rockets, HP Suckers, and other special artifacts used in battle.
In the Super Smash Bros. series
In Super Smash Bros. Melee, Jeff had a collectible trophy. In Brawl, Jeff appears as an Assist Trophy, using the Multi Bottle Rocket to attack opponents. These rockets fly through the level, damaging those they come in contact with, and appears as a sticker and a regular trophy as well.
The following are Jeff's trophy descriptions in the Super Smash Bros. series:
Super Smash Bros. Melee
- Another of Ness's close 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.
Super Smash Bros. Brawl
- 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.
