Undertale Love Stories

Crossmare| Weight

Nightmare sighed softly, leaning back in his seat. He was bored and was running out of ideas on how to kill or capture the Star Sanses.

It was honestly becoming annoying.

However, something else has been grabbing his attention. Cross was getting weaker.

Now, he knows Cross trains far more often than any one else, so he found it odd...

Sighing again, the King got up and walked to their medical wing to consult with the medic there... Or to get some info from his file.

The Sans raised an eyebrow at the King since it was rare for him to show up.

"Do you need something, my King?" The Fell Medic stood up, trying not to seem as short as he was.

The gooey skeleton looked down at the shorter skeleton.

"Has Cross recently come in for a check up?"

With how much Cross trained and goes on missions, Nightmare assumed the white clad skeleton would get a check up once in a while.

Yet, a mildly concerned frown formed on the medic's face.

"No... He hasn't for nearly a year..." He then focused on the King. "Do you need something from his file?"

The powerful monster sighed heavily, looking annoyed.

"Yes, but I need something recent, not a year old." His tone was bitter and had a snapping bite to it.

The Sans nodded, looking away before back to the King.

"If you give the order, I can have a mandatory check up on everyone."

The larger Sans narrowed his eyes for a moment, but relented.

"Fine. But no weird experiments. Just a normal check up, for once." He growled, leaving the room.

The doctor kept his word and started pulling everyone in for a check up.

Killer weighed a couple pounds more, he even grew an inch! His magic also seemed to have gotten stronger too.

Horror gained several more pounds, he was still as tall as he was before. However, his magic had a large increase and his stamina had gotten better too.

Dust weighed the same as last time, though he did get nearly half a foot taller. His magic also grew a little more unpredictable...

Last one in was Cross... Who oddly wasn't in the Castle despite that Nightmare had canceled all Missions till everyone took the check up.

The King growled a bit when he received this news, quickly dispatching the others to find the white clad monster.

After a small while, Killer found the Sans passed out in an AU... And it wasn't the good type of pass out either.

Hurriedly, he brought Cross back to the Castle, straight to the medical wing.

The Fell Medic's eyes widen in surprise, swiftly ushering the blind murderer to get their boss. The medic went to work on seeing what the problem was...

Nightmare was in the room the second he heard how Cross was found, an odd worried look on his face.

"What happened to him?" He hissed out, glaring a bit.

The medic glanced up for only a second before looking back to his patient.

"I don't know... Killer said that he was face first in the snow..." He muttered, checking the soul's beat. "His soul's beat is slow..."
