About the Au
The Plot of PhantomTale revolves around the characters being changed towards some sort of Phantom like body. Such as Sans having no legs and his hoodie always being on. He has those ghostly legs instead. Or Papyrus having more of a beastly like phantom appearance. When W'D Gaster created the core, Everyone in PhantomTale's code was caused by a glitch in a result of a change of appearance. They were instead banished into a Ghost Void for thousands of years, to float in an abyss of nothing but this green giant circle. Eventually, they fell into the Underground, when they came out they're physical appearance changed and some may have different abilities.
Another Problem was, PhantomTale's code was unstable, to stabilize the code one had to be erased completely of Code, this one was Asgore. No one remembered him.
Sans has no legs, instead, has that ghostly legs(kinda like how you see in Spongebob the flying Dutchman if you've seen it before). His hoodie is always on and walking through him isn't very......a good idea....(you get ectoplasm all over you.).
Papyrus has more of a beastly-phantom appearance and still has legs. He's like some sort of mutant skeleton.
W.D Gaster looks mostly the same. but however he's always floating, and the end of his outfit the little tentacle looking things are always going up and down.
Flowey is a Mohavea Confertiflora also known as the Ghost Flower. He is extremely translucent and hard to notice.
Toriel has no legs, and has the same type of legs as Sans. She doesn't change much except instead of fireballs she shoots a teal ectoplasm blast.
Undyne is a Warrior Ghost, who uses a Sword and Shield and protects the underground.
Alphys is a Scientist Ghost trying to figure on how to break the barrier
Mettaton's robot body just exploded now hes a ghost again
Asgore was erased from code.
Asriel is technically flowey.
Napstablook does not change as he is already a ghost.
Chara is the first fallen human. Has a black and white appearance with very dark hair.
Frisk is the eighth fallen human. has a black and white appearance with a black t-shirt, also with very dark hair.
Most of them just have a ghostly appearance now.
