"A familiar path with new steps taken..."
Storyshift is an Undertale AU created by voltrathelively on Reddit. Like Underswap, it involves some characters changing places role-wise with others while keeping their original personalities. What makes Storyshift unique, though, is that the characters are "shifted" in pairs into other pairs' roles, as opposed to with each other, such as Sans having Asgore's role and Papyrus having Toriel's role, while still keeping their original personalities, and relationships intact. There's also some modifications to the story that puts a twist on the original Undertale canon.
About the AU
Storyshift is said to possibly include other shifts, depending on Voltra's motivation. Some have theorized how the shifts were made, as in everything were changed on this Universe but there is nothing said canonically. A shift will show the Neutral, Pacifist and Genocide routes before proceeding to the next shift. Only the ten "major" characters, excluding Frisk, have their roles shifted, unless changed in another shift.
- Worn Dagger and Heart Locket are replaced with the Prop Chainsaw and the Hair Clip.
- Lilac is the soul color for curiosity.
- Flowey is replaced with a new flower called "Boogie."
