When Chara saw the gasterblasters surrounding Frisk's body, they kind of panicked. All too many times, they had seen that exact same sight. It didn't help that they felt the constant presence of Sans' telekinesis on their SOUL, holding them in place.

But there was a difference between then and now. Then, they could just LOAD. Now, if they died, it was all over. They couldn't SAVE, LOAD, or RESET. And with that knowledge, came fear. For all their life, Chara had done nothing but hurt the ones they loved, and the ones they hated, and the ones they were indifferent to. And all of it was to achieve power. Even that came from a desire to have fun.

But now, the fun was over. It had always been a game before. Now, it was real. And Chara had nothing to do. There was absolutely nothing they could do to survive. At least three hundred times, Sans had killed them with that exact same move, and they had dodged it exactly zero times.

Then, Chara began to calm down. They couldn't dodge, obviously, but they could survived. They had never really cared before. It was all just a game. But now, it was real, and Chara couldn't afford not to care anymore.

They were filled with DETERMINATION.

When the gasterblasters' beams hit, Sans smiled. The shot had rocked the entire Underground, and the dust from the impact still covered hundreds of yards surrounding the area.

Sans had won, finally. Or so he believed.

It was not to be so easy.

As Sans calmed down, his pupils reappearing, and the flame in his eye dying out, he hugged each of the gasterblasters before sending them off to roam wherever the heck it was that they went when they weren't around.

He was sweating. He hadn't realized just how much one attack could take out of him. Panting hard, Sans snapped his finger and teleported over to Undyne and Papyrus.

"hey, bro, hey undyne. i sure didn't expect them to be so tough. what do you think, undyne?"

"I can't even describe it. Not only were they stronger, faster, and more durable than m- Asgore, they seemed like they knew all of my moves. It was like they were prepared for everything I did. And… If you hadn't showed up when you did… I'd be dead, Sans. Thanks."

"no problem. it's the least i could do. how are you feelin', paps?"

"I AM FEELING ABSOLUTELY STUNNING! I HAVE EXPRESSED MY SINCEREST GRATITUDE TO UNDYNE, AND NOW I MUST GIVE IT TO YOU, BROTHER. YOU STRONGLY ASSISTED ME RIGHT THERE. OF COURSE, I THE GREAT PAPYRUS, COULD HAVE EASIL-"

"Papyrus, maybe you should shut up for a second, kay?"

"WHAT ARE YOU TALKING ABOUT, UNDYNE?"

"Turn around, Sans."

But Sans didn't need to turn around. His hand instantly ignited with blue flame as he thrust his palm forward to telekinetically throw Undyne and Papyrus out of the way. An instant later, he practically tripped out of the way of a sneak attack from the Fallen Child, alive and well behind him.

Turning around, Sans noticed some serious scratches and quite a bit of blood on the human's face and body, but no dangerous injury. Despite the rivulets of scarlet liquid that ran down the length of their face from their hair to their neck, they hardly seemed to notice pain.

In fact, they hardly seemed to be noticing anything.

Papyrus had seen Sans upset only a couple of times. When he went over the edge, his pupils disappeared, and Papyrus swore they were the deadest, emptiest eyes that had ever, would ever, or could ever exist.

Now, staring directly into Frisk's eyes, he knew he had been wrong.

"pap, i don't mean to alarm you, but i'm not sure i can deal with this kid. they're a hell of a lot stronger than anyone i've ever fought, and if they can no-sell thirty gasterblasters like nothing, then we're in trouble. and i'm tired too. i can't hold them off forever. take undyne, and evacuate, now."

"He's going to take me, and evacuate? No way! Do you have any idea who you're talking about? I'm not running away!"

"i'm not gonna force you to do something you don't want to. but if you stay, undyne, you're gonna die."

Blunt, but true. Sans obviously wasn't in a good mood.

Undyne growled in sheer frustration. As much as she hated to admit it to herself, if Sans couldn't beat this kid, she couldn't either. None of them could.

The human swung again, and Sans dodged, but only narrowly. He was getting tired. Lifting his palm, Sans made a bed of bones explode out of the ground beneath the Genocide Frisk, but the human simply leapt into the air to avoid them and then slammed their fists downward into the ground to shatter them.

Dashing toward Sans, they raised their knife to stab him, and he was barely able to push them away with telekinesis before they landed the hit. He snapped his fingers, summoning a few gasterblasters to fire at the human, but they were able to easily evade the shots. Their speed, strength, and durability were going up by the second, and Sans didn't like it.

Suddenly, the human disappeared. Sans looked around, and cursed under his breath. He had blinked.

The skeleton honestly didn't have a clue where the next hit would come from, but simply waited what seemed to him like a sufficient amount of time, and then sidestepped, inadvertently dodging a blow from behind that would have sliced him vertically in two.

Frisk charged Sans, who struggled to dodge attacks that were coming in at incredible speeds. He was still vastly faster than the human, but he was tired and unnerved, and Frisk was also attacking with a ferocity and randomness that was catching him off guard. Suddenly, Frisk took a step forward, but, instead of attacking directly, swung around in a circle and slashed from the side, the opposite side that Sans expected. The skeleton realized that he wouldn't be able to dodge the attack, and did his best to prepare for it.

He closed his eyes, braced himself and… felt absolutely nothing. Looking forward, he saw the Genocide Frisk's knife blocked in place by the knife of a very different Fallen Child.

The cavalry had arrived.
