Dr. Andonuts

Dr Andonuts is a scientist. He is the father of Jeff, who is one of the people accompanying Ness in EarthBound. He is a supporting character in both EarthBound and Mother 3.

EarthBound
Dr. Andonuts is first encountered in the lab when the player controls Jeff. He gives the player the Sky Runner so they can rescue their friends. Much later in the game, he creates the Phase Distorter with the help of the Mr. Saturns, unfortunately it gets stolen by Pokey Minch. He later creates another Phase Disorter.

Before the fight with Giygas, he transfers the bodies of the party into robots so that they can survive going to the past in the Phase Distorter 3.

Mother 3
He reappears in Mother 3, working unwillingly under Porky doing Chimera experiments. He is first hinted at in the game when a Pigmask tries to remember the name of the scientist who came up with the Clayman system.

The player first finds Dr. Andonuts on the Chimera Laboratory hidden in a trash can, though any attempts to talk with him will result on him not getting out of his hiding place. Later, when Lucas is being attacked by the Ultimate Chimera he gathers enough courage to tell him the weakness of the Ultimate Chimera, though not before suggesting to use Boney as bait. After the Ultimate Chimera is defeated by Salsa, he helps Lucas access Doria's Needle by giving him his choice of a chimera to drain the pond water covering the Needle.

He later reappears near the end of the game alongside most of the Tazmily villagers, telling Porky that he won't be working for him anymore. It is also revealed that Dr. Andonuts assisted in the creation of the Absolutely Safe Capsule, and he explains how once it is sealed it cannot be opened.
