"tl;dr - eat shit, faggots"
– Dr. Andonuts

Dr. Andonuts is the main and final antagonist from Earthbound: Halloween Hack by Toby Fox.

He also plays as the final boss.

He was originally a sane man until you destroyed "The Id" which was his intelligence. After that, he starts spewing swears and insults at the main characters.[1]

He appears to have done nothing wrong (makes you wonder if you're the villain here) until now.

Editors note: In the hack, Dr. Andonuts blames himself for killing his son, Jeff, by sending him through the phase distorter (labeled as a death trap in the hack), along with the other protagonists in Earthbound.


He has purple skin (whether that is because of the flame surrounding him is up to debate), pink-ish hair (counting his mustache), and wears a pink-ish labcoat. He has red shoes and black glasses/shades.

Editors note: in Earthbound, when a character, humans in particular, are turned evil by giygas, they turn purple.

So Andonut's colour (skin and garment) is only to show that he's become consumed with evil thoughts.


He uses basic attacks and strong PSI (magic) attacks: Rockin, then Fire, then Freeze. The most infamous being his "PSI Bitchkill" (Starstorm) attack (which deals instant KO damage but the player is kept alive because of the rolling HP system in Earthbound).

He seems to regain some of his intelligence after killing him; as he calls himself pathetic, says that Varik reminds him of his son's friend, but still has most of the rudeness; saying that he's going to beat the shit out of you if you ever meet him again (although, in very broken up dialogue as he's struggling to stay alive, he doesn't even finish his sentence).


All we can take from the Id is that he wishes to resolve things peacefully; but once he loses his intelligence, he is very rude and aggressive, constantly swearing.


  • His theme, Dr. Andonuts' Rage, is the first version of "Megalovania". (Editor's note, Andonuts' Rage didn't exist, it was always called Megalovania)
  • Because of The Halloween Hack, some players think that Dr. Andonuts from normal Earthbound is a villain (though, whether he was one in The Halloween Hack is up to interpretation by the player). (Editor's note: this whole point is probably false as people can easily differentiate between the original game and a non-canonical fan hack, but I don't want to spend the next few minutes lurking in the starmen forums)
  • He may have knowledge of timelines, like Sans. (Only hinted at in dialogue, not used in the plot of the game)
