UNDERTALE: MetaProjections
aka, the AU where the Anomaly aka Player appears in the form of a dog. Why? Because Toby's a dog. But Toby's a human in reality... so that could only mean one thing.

Its a author insert? No. EVERY human user from reality appear as wacky dogs in the Underverse. Sorry, its canon /jk


Thwir name gets kind of confusing when the Fallen Human was named after the anomaly and the entity is referred to in game by the name of the Fallen.

While technically and definitely not a dog, this shift in appearance inside the world seems to be because one lazy dog didn't intend for anything that wasn't a dog to gain debug access after pulling off the "let there be light" bark.

Gist of how they work tho, simply being they can latch onto a soul and possess it by using the souls own power against the host body. They only need a soul with the least bit of determination, be it monster or human, and they can basically possess it. Though certain things such as a physically strong body with an opposing will can make possessing difficult.

They can only really be seen by whoever they're hijacking at the moment, and have to "type" their words into speech in real time instead of on the fly like the UT characters. The player can physically try speaking in this form but it'd sound like a loud omnidirectional bark that can only be understood by dog monsters, wack.

Also, yes I redesigned Frisk and Chara here and yes j gave them yellow skin. Their stripe was already skin tone anyway so this just matches better, at least imo.
