Undertweak

Undertweak is a Switch Up AU of Undertale. This AU does not always follow relationship rules.
== Character Changes ==
* Gaster: Gaster appears in the role of Frisk. He was the second-to-last royal scientist of Chara, predating both the Mad Dummy and Sans, but absorbed a human soul and became a human-monster amalgamate that the player now controls.
* River Kid: River Person appears in the role of Monster Kid, and often hangs out at the Waterfall. His idol is Papyrus.
* Sans: Sans appears in the role of Alphys. He is the royal scientist of Chara, and is never fought.
* Papyrus: Papyrus appears in the role of Undyne, and the brother of Sans. He still belives in Gaster.
* Napstablook: Napstablook appears in the role of Sans. He can be fought on both Genocide and Neutral routes, and when he "dies" on the final Genocide attack, you are forced to spare him as the text reads "But it refused." 
* Mettaton: Mettaton appears in the role of Papyrus, and is the cousin of Napstablook. He is much more energetic. 
* Undyne: Undyne appears in the role of Flowey/Asriel. She died from poison previously, but her determination was transferred into the soulless flower. 
* Alphys: Alphys appears in the role of Chara, and like Gaster, she absorbed a human soul in order to be against the monster race. She is the one you control on a Genocide route, and her theme is shared with Napstablook's, since this is a MegaloChara AU.
* Asriel: Asriel appears in the role of Asgore, and she rules the underground. She has two children, Alphys and Undyne. 
* Chara: Chara appears in the role of Toriel, and caretakes the Ruined Basements.
* Frisk: Frisk appears in the role of Muffet, and sells human food items in the Hotland. As a miniboss, Gaster encounters her on most runs.
* Monster Kid: Monster appears in the role of Grillby, and is never fought. He (she?) opened up the restaurant "Monster Kid's".
* Dreemurrbot: Asgore appears in the role of Mettaton. He was originally was a ghost, but Sans transferred him to the robot body. 
* Toriel: Toriel appears in the role of Napstablook, and is a purple ghost in the Ruined Basements.
* Mad Dummy: Mad Dummy
