Irreplaceable || A Kustard Fanfiction

(Currently on Hiatus)
After a whole so-called 'Multiverse Collision', multiple AU's have clashed together as pieces in some sort of puzzle. How it happened? Nobody knows for sure. However, even if there were multiple AU's, Undertale (the original) is the one that's the core of them all.

Fell was one of those that were in the collision, but the thing was.. He absolutely despised the Classics. Why? Because they thought they were so much better, at least that's what he thought and saw for himself.

But when someone manages to convince him, he goes over for a visit to the original timeline, deciding to see for himself just how the Classics really were.

Yet what he didn't know was that he was gonna find a person who would change his opinion on the Classics completely..
