When both of them appeared inside the Mansion, Sans had to grab Frisk and pull her down as a couch came flying at them. "GET DOWN!" He shouted protecting her.

Frisk gasped in shock at the massacre that was the living room/kitchen. She rolled off Sans and tried to stand but her legs were glued to the spot. Sans growled; his left eye brimming with magic.

Undyne was chasing what appeared to be another Skeleton monster around the house. "Get away from me, ya crazy bitch!" Red ran wheezing heavily; sweat dripping off his skull.
"GET BACK HERE YOU TWERP!" She screamed after him, blue spears flying past his skull.

Sans tilted his skull.. his right pinprick vanished as his left eye caught site of two more Skeletons. They were panting hunched over grasping their knees. Stellar and Sansy had been trying to catch Undyne, but her resolve and show of strength were too much for them.
"The..fuck is going on!?" He stood clenching his hands at his sides.

"BROTHER!" Papyrus ran from his hiding spot and over to them. Blueberry was clinging to his shoulder; tears streaming down his cheekbones. He was terrified; the Undyne from his world was never this way.

"Papyrus what's goin' on! Who are these guys!?" He gestured with his hand at the other skeletons. "THAT DOESN'T MATTER RIGHT NOW, SANS! WE HAVE TO CALM UNDYNE DOWN BEFORE THE KING AND QUEEN GET HOME!"

Papyrus took ahold if Blueberry and placed him in Frisks lap. Frisk snapped out of her shocked state and into the starry crying sockets of Blueberry.
"MAGNIFICENT SANS, THIS IS FRISK, THE HUMAN. STAY WITH HER WHILE WE DEAL WITH UNDYNE!"

He gave a quick nod burying his skull in Frisk's chest clinging to her like his life depended on it.
Frisk blinked a few more times before wrapping her arms around the scared skeleton.

"It'll be okay, I won't let you get hurt." She reassured Blueberry softly. He looked up at her from her chest and his face was dusted blue. He had stopped crying and could only stare at Frisk in wonderment.
Sans grimaced at the way he clung to Frisk.

"Outta the way!" Red shouted motioning for them to move. His red eye light caught site of Sans and he almost faltered. He caught his breath pushing past them and out the front door.

Sans growled whirling around; his fingers out stretched as Undyne came running around the corner. A wicked grin plastered across her mouth. Suddenly she felt a ping in her soul and it had been turned blue. She couldn't move; she growled aggressively trying to fight the magic that had her frozen.

"THE FUCK SANS!" She snarled; eyeing the skeleton.

"I could should be asking you the same thing." He replied darkly. Papyrus stood behind his brother, "UNDYNE WHY DID YOU ATTACK OUR RELATIVES?"
Sans brow bone arched at Papyrus' question.
'Relatives..?'

Undyne struggled more against Sans magic. Sans brought his fingers together almost closing his fist, squeezing Undyne more. She let out a cry of pain glaring at her captor.

"A-Alphys.." She hissed trying to breathe.

"What about her.." Sans replied calmly. Stellar and Sansy slowly appeared behind Papyrus. "She keeps asking where she is.." Stellar panted; he still hadn't regained his breath.

Sans glanced back at the two noting they looked similar to when he was shorter. Undyne took this as a chance and with a loud battle cry broke free if Sans magic, landing on her feet.

Sans cursed lifting his fingers again but had to teleport to dodge as a table came flying at them. Papyrus smashed the table with his bone attack protecting Frisk and Blueberry.

Undyne made a mad dash for the door quickly looking for Red. Before she had time to gain her barrings a bright red laser shot towards her.

She barely had a second to jump out if the way and barrel roll to the front lawn.

"Tch, you got lucky bitch.." Red huffed. His eye was consumed with his red magic; a giant Gaster Blaster was hovering behind him; it was slightly more menacing with the red glow.

"WHAT DID YOU DO WITH HER!" Undyne took her stance summoning more blue spears.

Sans and Papyrus ran outside. Sans stared in awe at the other blaster.
'..he's..me!?'
Red held his fingers at ready. Red mist twirling around them. "I ain't done nothing to anybody" He was losing his patience. This Undyne was definitely like the one from his world. Maybe a little weaker; but same aggressiveness.

"UNDYNE, YOU MUST STOP BEFORE SOMEONE GETS HURT!" Papyrus shouted. Frisk looked down to the small skeleton. "S-Sans was it?"

Blueberry gave a nod, "YES MY NAME IS THE MAGNIFICENT SANS!" Frisk smiled; "I need you to stay here; I have to go help them." Frisk eyed the entrance; hearing shouting. Blueberry whimpered but slid off her lap.
"HUMAN, PLEASE BE CAREFUL!" He watched as she got her strength back to stand. He reached out for her but quickly pulled his glove hand back.

Frisk quickly ran outside and past Sans and Papyrus. Sans tried to grab her by the shoulder but she was too quick. "F-Frisk! It's too dangerous!"
Frisk ignored his warning and ran towards the battle.

Red was dodging spears left and right. He sent hundreds of bones towards Undyne. She used her spear spinning it quickly to form a shield deflecting all of the bones. "UNDYNE!" Frisk screamed at her.

Undyne blinked at the voice. "F-Frisk?"
"AS YOUR PRINCESS; I COMMAND YOU TO STOP FIGHTING!" Undyne glared to where Frisk was. Excitement filled her soul; and she glared at Red who stopped to eye the human.

"As you wish.. Princess.." Undyne muttered in defeat. Frisk sighed in relief. She never liked playing the royalty card; but she knew Undyne couldn't refuse a royal order.
'Thank the stars..' Sans and Papyrus ran over to you; Undyne walked over to you still mad about everything.

"Sorry.. I just can't find Alphys.. shes not responding to any of my calls.. she never does that." She clenched her fists looking at her boots. "Then.. that guy!" She pointed a finger accusingly at Red. He glared back.
"Was acting suspicious!"

Red huffed crossing his boney arms over his sternum. "Didn't even give me a chance ta explain.. crazy bitch.." He growled.

Undyne got in her fighting stance, and Red took a defensive one.
"STOP IT, THE BOTH OF YOU!" Frisk yelled in frustration. The mansion was a wreck there were holes in the walls and the front entrance was missing.

Undyne hissed, but straightened back up.
Sans rubbed the back of his skull eyeing Red suspiciously. A strange tug on his soul he didn't recognize had him at a loss.

"Look Undyne; we'll find Alphys.." Sansy and Stellar had been standing on the porch watching the fight when they heard the Docs name. "Hey.. isn't Alphys that doc?" Sansy questioned Stellar. "Yeah, her and Undyne are together in this world too I guess.."

"We know where Alphys is.." Stellar shouted to the group on the lawn. Undyne perked up and Sans and Papyrus turned to face the other two skeletons.

"What!? Where!?" Undyne raced forward; Sans and Papyrus followed after.
Red sent his Blaster to the void and watched from a distance.

Everyone hadn't noticed a black sleek car pulling in the driveway.
Frisk whirled on her heels when she heard a car door slam.

Her jaw dropped at the site.. tall; white furred monster wearing a business suit. Long ears and a tuft of white hair on his head; adorned by medium sized horns.
'A-asriel!?' Frisk screamed mentally.

Asriels eyes turned black at the site of his destroyed home.

"WHAT IS GOING ON HERE!?" He screamed; his fur bristling with rage.

Sans flinched and glanced back, "Shit.."
