Monster or Beast?

Theory

Sans found himself pacing back and forth in his room. It had been a few days, unsure as to what he was to do. It just seemed that no matter what, he just couldn't think of a way to figure out why this was happening to him. The skeleton knew that he had somehow turned into some kind of beast, but unsure as to how it could have been caused or when it had happened.

He knew that he felt different back when the barrier shattered but nothing happened then. Then of course, there was the fact that there had been no news or anything of the sort when he was first on the surface with everyone else. Nothing about a beast coming about after they got to the surface but... then again there was the changes that had happened to his own body.

Looking back down at himself, he remembered how he got really tall. Still shorter than his brother, but still much taller than he used to be. Maybe nearly twice his height if that. Letting out a soft sigh, the skeleton monster just wasn't sure what it was that he could do. Then of course there was the fangs, that was new for him as well but it just made him all the more confused by the whole thing. Yet, the one thing that was still more baffling was the fact that he turns into some kind of weird beast!

Sitting on his bed, Sans let out a groan as he stared at the ceiling of his room. It just seemed as if everything that would seem like it was going good for him in some way or another there was always something that would screw him over in some way or another. It always seemed to happen when he thought something good was happening in his life and then there was always that one thing that would mess it up for him.

Frowning, he placed his hand on his chin he was thinking on what he could do to try to figure this out. It just seemed like he had hit a brick wall. Which he had. Honestly, he had no way of trying to figure this out. Of trying to scan himself to look for any abnormalities or anything of the sort. He hadn't even been able to figure out what was happening to him until it happened, or at least until he saw the footage.

Letting out a hum to himself, Sans figured maybe there is one person that could take a look at him. As well as keep this a secret from anyone should it ever get to that fact. Narrowing his sockets, the skeletal monster pushed himself up from his bed as he made his way over to his closet and pulled out his signature blue sweater before starting to walk down the stairs. Thankful that Paps was out for the day, he was on some kind of date or outing with Mettaton. He didn't care about that though right now.

The only thing that mattered was to try to figure out what is wrong with him. 'And to make sure that... I don't hurt anyone. I don't want to hurt Frisk, Papyrus... or anyone.' Sans thought to himself before taking a deep breath, hoping to calm himself. His SOUL felt like it was beating quickly in his chest like a normal human's heart would. He was still internally panicking, and feared for the safety of those around him.

So, if he could do something to help suppress it, then he would do so. No matter what may come his way, but Sans knew that it had to be done. Because that form of his, wasn't just dangerous but it was seriously cutting into his sleep and exhausting him to the point that he felt like he would sleep through his shifts.

Shaking his head, the monster slowly started to make his way down the stairs and out the door. Looking up at the sky, the skeleton monster noticed that it was noon. That would mean it would just be him... and Alphys right now since Undyne would be at work herself. Smirking a little, the monster reached up and snapped his fingers, disappearing in a blue light and he was gone.

Appearing in front of the house of his good friend, Sans looked upward before letting out a soft sigh. He knew that this was something that had to be done, didn't help with him feeling so nervous. There was just no way of knowing if she would even find anything in the first place. It just made the skeleton curious as to what they would even find in the first place.
