Frisk.

Frisk.

"Frisk!"

The small childs' brown eyes fluttered open, blinking a few times to clear the blur before they met the familiar face of their tall skeleton friends. Stretching their arms, they were confused to find that the shorter skeleton was no longer beside them, which was really out of character since it was still dark outside and obviously night, or at least early morning. Sans wouldn't usually wake up the afternoon or late morning when it came to full sleeping and not just a nap.

A finger pressed against their lips when they opened their mouth to say something, as Papyrus pulled them off the couch and set them down on his shoulders. A silence fell on them as he headed for the front door, looking back once as if to check for someone. Probably Toriel, Frisk noted as they clung onto the smooth fabric of the cape around Paps' shoulders.

"Shhh," the skeleton urged as the door creaked open, Frisk leaning to the side to look as their hands rested on the top of his skull for grip. What were they supposed to be looking at, exactly? They had so many questions as the scene processed in their head, they didn't know what was going on and why Papyrus seemed to want to show them something outside – didn't he know not to go outside when it was dark?

Toriels' house was isolated from streets, she had politely asked for a house away from the humans but not too far in case she found a career opportunity as a teacher. As a result, the only surroundings of the house was lots of grass and a spooky looking forest that separated the area from the small town. Papyrus and Sans liked to goof around with the children that dared to come too close, Halloween was when they most often showed up.

There was a faint glow of blue in the distance.

It was in the trees… At least it appeared that way.

Why was Papyrus dragging them out here in the first place?

They squinted their eyes to get a better look, before looking down at their skeleton friend to see his reaction. To add to their confusion, Papyrus remained completely silent and slipped through the door, carefully shutting it behind him as he now headed towards the blue light. Frisks' eyes widened in panic and they gently tapped a finger against his skull.

"Pap, don't go towards it – you don't know what it is!"

The urgency in their voice was very real, they had enough common sense to know where situations like this would go.

But they were being ignored, which came as a surprised to them. As much as Papyrus seemed to take pride in himself, he usually took the opinions of others very seriously… Unless it was an insult, to which he would happily assume they were speaking of themselves. His steps only quickened as the blue glow grew closer, and brighter. It was almost like a cloud of bright blue mist, covering the trees so much you couldn't even tell if an actual forest was still there or not.

A growl.

Papyrus stiffened, gently tugging the child off his cape and setting her down on the ground. He seemed incredibly focused on something in the blue mist – a shape moved to the side, and Frisk wrapped her arms around his leg, eyes widened in terror. The shape let out a snort then another growl, moving closer towards them.

"Sans..."

Two skeletal paws came into view, along with the rest of a body. It was a complete skeleton – but it looked nothing like Frisk has seen before. It had the anatomy of some sort of lizard mixed with canine, and was a few inches taller than Papyrus. Blue mist flowed out of it's sockets, large blue circles that sufficed as pupils contained in the eyesockets. It had short legs but a rather long neck, with sharp spikes that ran down it's whole vertebrae. It's bottom jaw was split down the middle, and it had sharp, jagged teeth and three spikes emerging from the back of it's skull.

"Sans?" The child meekly repeated, looking up at Papyrus with questioning eyes. Why had he said his brothers' name? Surely this wasn't the short, loveable skeleton they knew? He was a humanoid skeleton – not some canine monstrosity! It did look strangely like his 'Gaster Blasters', though…

A gloved hand pushed them back slightly, as the tall skeleton ventured further towards the beast, a hand carefully outstretched. "You've switched again, brother… Is that what was bothering you earlier?" His voice was louder than usual, but not unkind.

Sans tilted his head to one side, freezing up momentarily before snapping his jaws together a few times. He let out a low, aggressive growl again and moving a few steps to the right. He was beginning to circle the two, eyes glowing a bright blue and pupils dilated – Frisk recognised that horrid expression his eyes showed, it was that of a predator.

He didn't recognise them.

They were his prey.


"Human, you need to get out of here, okay?" Papyrus rested a hand on their shoulder, a flicker of orange present in his eye. That was new, but they were brothers so it would make sense for him to also have magic – though perhaps not as powerful as Sans? Frisk wasn't sure. But they nodded their head and took off into a sprint. They only went a distance away before crouching behind a bush, they wouldn't leave their two friends like that. What if they needed help?

"I'm going to have to change too if you won't listen to me, brother."

The beast made what sounded like a scoff, barely noticing that the human had slipped out of the area. He seemed mostly focused on the tall skeleton, pupils as thin as sticks now – Sans lurched forward to push his front paws right onto the chest of Papyrus, who made no move to dodge and was easily pinned to the ground.

A mist of orange shot out around him and mixed in with the blue, as a few sickly noises of bones shifting and snapping sounded around the area. What was happening? Frisk squinted their eyes, they couldn't really see anything until it all calmed down – they heard a loud snap and the chestpiece that Papyrus wore now slid on the ground, snapped in two. Panic clutched at their chest, was he okay?

There was a loud roar that echoed through the trees – or was it two?

Now there was a second beast…. A red cape loosely hanging from it's neck… Frisk quickly put two and two together.

Papyrus was huge. He was easily taller than his brother, so it seemed height was the same between beast and humanoid for the skeleton brothers. He had a much more finer and smooth skull shape compared to Sans, and had two long horns that jutted out from the back of his skull. He had the same jaw design as Sans, the split bottom jaw and jagged teeth. One thing they noted was he had a much longer tail – with what ended with something that looked similar the the end of a spear. Spikes ran down his whole spine and he had a much more lanky figure than Sans, with longer legs and a shorter neck.

Papyrus looked more reptilian than Sans in their eyes, almost like a dragon without wings.

Gaster Blasters had always reminded them of dragon skulls, anyway.

The two brothers opened their jaws and roared at the exact same time – the sound was almost deafening, before they lowered their heads and rammed the top of their skulls against eachother. It was like watching buffalo fight, the horns make clacking sounds as they hit together and the two beasts' strength was matched. While Papyrus had size, Sans had quite a lot of strength.

Frisk felt trapped. They couldn't watch their friends fight like this, they needed to go get help but they couldn't exactly leave either.

"Frisk? Frisk, are you there?"

No, no! They turned around and sprinted towards the voice, waving their hands in distress. Toriel needed to get out of here, she would easily be killed if the two set their sights on either of them – they seemed to be more relying on instincts than the mind in that form. "Toriel, you need to get out of here, now!"

"My child, what's wrong?"

As if on cue, Sans was thrown in their direction and slid across the dirt, slamming into a tree and falling onto his side. It seemed he had more HP as a Gaster Blaster, or simply was just tougher to lower the health of. He lifted onto all fours as Papyrus approached – claws digging into the dirt below as the two beasts stared eachother down.

Blue welled up in ones mouth, and orange gather in the other.

Frisk firmly grabbed the paw of their shocked mother, pulling her paw and trying to drag her from the scene. Toriel simply refused to move though, staring blankly forward at the two clashing beasts.

A jet of orange went from Papyrus' mouth, and a blue from Sans'.

Then they hit eachother.

The explosion was strong and sounded louder than thunder, the sheer force of the two beams colliding knocking Frisk and Toriel back a fair distance away. Both lost a few HP, and the two skeleton brothers were also knocked back by the own force of their combined blasts. Papyrus was knocked further away from the group, but Sans was knocked quite close to the two.

How unlucky.

Turning his head slowly, magic still seeped out of his eyesockets as the predatory gaze settled on Toriel – the biggest prey at the moment. His rival seemed to have been swept away for the time being, which gave him lots of time to clamber to his feet.

Thump.

Sans came closer to Frisk and Toriel, who took a few steps back as the skeleton came closer with every large step he took. His eyes had no remembrance in them – only a lust that was extremely unsettling to see from the usually laidback persona they would see everyday.

Thump.

His back legs kicked into action as he lurched forward towards them, jaws parting as wide as they could and aimed to lock down straight on Toriels' shoulder. Frisk reacted quickly and used all the weight they had to push Tori out of the way, which was just enough to stop the main blow but did send Sans flying over them – the claws on his back feet locked onto Toriels' shoulder and pulled her along with him.

Where was Undyne when you needed her?!

Frisk wasn't going to fight him, they were a pacifist and would never hurt their friend regardless. They had to find a way to reverse whatever transformation he had been through, or at least jog his memory so he wouldn't attack them. They had to do it before Toriel was forced to fight him, at least that was the outcome they suspected.

"Sans! It's me, Frisk!" They raised their arms and held their breath and attentive blue eyes fell on them.

To their surprise, there was a strangled growl in response – as if he wasn't really sure how he was supposed to be responding. Sans lifted off Toriel who was very dazed but luckily not too badly injured, there was a lot of force involved in knocking her over. The canine-like skeleton carefully stepped towards the human, eyes searching for a weak spot.

"Don't you remember?"

Breathe.

"Why are you attacking us, Sans?"

There was a snort in reply along with an aggressive growl as he got closer, pupils flickering between dilated and full a few times. The plan didn't seem to be working, how were they supposed to get their friend back? Placing a hand on their chest, they looked towards Toriel for a moment before reaching out a hand.

"Sans, please -"

Too late.

The jaws locked around their lower arm as the predator took his chance to strike, drawing blood as he swung them across the ground. It felt like their arm was going to snap off, they prayed to god that Toriel had snapped out of it now.

A burst of flame hit the ground just below Sans' paws, which startled the skeleton and he released his grip on Frisk – who fell onto the ground with a pained cry. A few more fireballs hit the ground around him, which was just enough to confuse and distract the beast so they could compose themselves.

"Frisk! Oh, I'm so sorry I wasn't helping sooner!" Toriel was at their side immediately, holding them close to her chest in a protective embrace. "I hope you are not too badly hurt, my child," she paused. "I do not know how to deal with these skeleton monsters… Where are Papyrus and Sans?"

They could already see Sans was coming back his senses, which wouldn't look good for either child and mother. "They are Sans and Papyrus, mother." Frisk rushed out, "Please don't hurt them! We don't know anything about these forms of theirs, who knows what could kill them?"

Toriel opened her mouth to say something before they were both knocked back across the ground – their HP was getting considerably low now, and Sans seemed hell-bent on killing them. He had charged at them head-first, and was now opening his mouth and letting magic gather up inside it. Ready for another blast.

Thump.

Frisk snuggled themselves deep within the purple fabric of Toriels' clothes.

They were both weak from being knocked around.

Thump.

The blue was now shining brightly inside his jaws.

Toriel held the child closer to her, resting her chin on top of their head.

Thump.

They both squeezed their eyes shut and waited for the blast to hit them.

But it didn't.

There was a loud yelp as Frisk opened their eyes slowly – they had expected to be staring into a bright blue light that surrounded them but was now met with a larger skeletal beast holding Sans under it's grip, orange eyes staring directly at them and Toriel.

Holding their breath, they stretched out their hand.

And tried again.


This is my first time writing an actual action scene so give me a break.
Sorry for any mistakes and/or it seeming like I slacked off, I'm kinda sick today.

Hope you're enjoying it so far. Thanks for the reviews.
Peace.
