Handplates what if Fan-fiction. (Undertale Fan-fiction)

In case you don't know, Handplates is made by zarla (http://zarla.deviantart.com) and more specifically, this (http://zarla.deviantart.com/art/That-was-90-gravity-625891809) comic. If you haven't read the comics then most of this won't make sense to you. Plus there are plenty of spoilers. Anyway, back to what this story is about (spoiler alert) when
1-S (Sans) is getting his eye repaired after WD Gaster (the evil scientist) broke his eye which means he can't see out of it or glow his eyes at all (Glowing eyes will be explained in the first chapter) in the comic, Gaster is trying to fix 1-S's right eye (the one that was broken). However, as he starts to repair it, there was a surge at the core (where the underground gets it's electricity from) and 1-S's right half of his skull is blown up. (by the way, the 3 people down here (Wd gaster) (1-S) (2-P) are skeletons). My story is about what would have happened if it didn't explode and Gaster proceeded to fix the eye.
