News got around quick about Toriel's death, even Asgore was nowhere to be seen. Undyne sat on the chair besides Sans bed, he was awake but very weak. He was devastated about the fiance's death, but hearing Frisk was the cause nearly killed him. Sans held Undyne hand, he was in great pain and needed to know if somebody was there. "I-Is it true?" Sans asked, turning his head slowly to Undyne. "Did T-Tori really d-die?" Sans asked, Undyne looked horrified. She remembered Asgore calling and panicking about Tori, finding her dust on the grass and bloody footprints around it. How his voice shook as he spotted, then hung up on her. Undyne didn't know what to say to this co-king, he was her boss but she had to be honest. Undyne gulped and closed her eyes, gripping onto the Skeleton's hand. "I'm so sorry, I really am..." Undyne said, Sans smiled. "I-Its okay... N-Now I know... If I die... T-Tori and I will be t-together...." Sans said, he took a deep breath. Undyne was nearly to tears, her grip grew together as she stood up. "I will avenge her... I will show this human it was a MISTAKE killing Toriel" Undyne walked out, Sans slowly turned his head to the door. "I believe in you...". Undyne stood at the garden, where Toriel had died. Her hand raised in the air summoning a spear. Finally Frisk appeared, their knife was covered in blood. Undyne chuckled, she took off her eye patch. "So to think your all that? That you can kill just about anything and win? Ha! Well try and get pass me!" Light glows around Undyne, her theme began to play. "Your gonna have to try a lot to kill me!"

Frisk's soul glowed green, meaning she entered the Undyne Fight. Undyne launched several spears at her, Frisk dodged and jumped in the air. Slicing the air a large, red cut flew towards Undyne. She lost damaged, Frisk smiled and kept swinging. Undyne dodged and launched a series of spears at Frisk, blood spilled and poured but she made it. Undyne grabbed a spear and chuckled out loud. "Hahahaha so your really determined huh? Well so am I, there is no way your breaking MY DETERMINATION!" Frisk Chuckled at this, and showed her black gooey eyes.

*You tell Undyne what would happen in somebody she loved died in front of her

Undyne flinched, she dropped her weapon. Frisk gave a sweet smile, she glitched before summoning ASGORE. Undyne stepped back, sweat began to drip down. We picked up her spear again, ready to attack. "Let. Him. GO!" Undyne yelled, Frisk chuckled. Her knife aimed and sliced Asgore's throat, Asgore's eyes widened. He collapsed onto he ground, before fading to dust. Undyne just stared at where her boyfriend was, her grip grew tighter. A small growl was placed onto her lips, she raised her head up. "OH! YOU WANNA GO THERE HUMAN, WHY DONT YOU GO TO HELL TWICE!" Undyne pointed at Frisk, a line of spears launched at Frisk. Frisk glitched from one spot to another, avoiding Undyne attack. Undyne was to caught up, she didn't notice Frisk was right in front of her.

SLICE!

Undyne froze, blood dripped from her lip. She chuckled and looked at her hands, they were shaking. "A-And here W-We thought we w-were Monsters... Hehehehe... Y-You are so m-much worse" Undyne began to melt she could feel her grip loosening from the world, from the life she once had. Undyne chuckled as she began to melt. "B-But now that H-Humans we with us! T-They will fight YOU, F-FIGHT TILL T-THE END! Y-You will n-not destroy Humanity! Y-You will not destroy our kind..." Undyne soon faded away, but before she did. She said one last thing. "We will carry on, with or without you!". Word began spread rapidly, two lives were lost that day. Or three, counting Toriel. Undyne's soul floated above her dust, Frisk grabbed it quickly. Absorbing it, she gained more power.
