Jeff

Jeff (full name presumably being Jeff Andonuts) is a boy from the town of Winters, and is one of the main playable characters in EarthBound. Although he does not have the ability to use PSI like his fellow teammates, he is very intelligent. He uses his knowledge to repair broken items, and use them in combat. His father is Dr. Andonuts, well-known for being a brilliant scientist. Jeff also has the ability to spy on enemies.

History
Jeff has lived at the Snow Wood Boarding House ever since he was an infant. He is close friends with Maxwell and Tony, who also live there. One night, he recieved a telepathic message from Paula, telling him that he is the only one who can save them. Tony momentarily comes with him around the boarding house to help him break out, and Maxwell supplies him with the bad key machine. After jumping over the boarding house's gate, Jeff picks up the Bubble Monkey from the local drugstore, and begins to head south. When they reach Lake Tess, they encounter, and ride on her to southern Winters. They then go through Brick Road's maze, and pass through Rainy Circle as well. While Bubble Monkey leaves Jeff for a girl monkey, Jeff finds his father's laboratory, and briefly reunites with him. He takes the Sky Runner to Threed, crashes into Ness and Paula's dungeon, and uses the bad key machine to help them break out. Jeff then accompanies them for the rest of the game.

Later, in Fourside, Jeff helps Ness in rescuing Paula from Mr. Monotoli. He also repairs the Sky Runner that crashed in Threed so they can fly to Summers, along with the yellow submarine in Dungeon Man in order to get to Deep Darkness.

At the end of the game, Jeff leaves his friends to stay with Dr. Andonuts, and also recieves a letter from Tony.

Spying
Jeff has the ability to Spy(Japanese: Check) on enemies, which lists their offense and defense, along with one of their PSI weaknesses. It also lists the item that will be dropped at the end of the battle.

It seems to be based on the Check command from Mother

Repairing objects
Jeff can repair broken items when he rests at a hotel. The chances of him repairing an object depends on his IQ, and the amount of attempts he has tried to repair any objects.
 * The first time in the game Jeff attempts to repair an item will have a 100% chance of succeeding.
 * If the previous attempt had a 100% chance of succeeding, the next attempt will have a 25% chance of succeeding.
 * If Jeff succeeds in repairing an item that he had a 25% chance of succeeding on, the next fix will have a 100% chance of succeeding.
 * If Jeff does not succeed in repairing an item that he had a 25% chance of succeeding on, the next fix will have a 25% chance of succeeding.
