A/N: So are you ready for some more death? Because there's death, but damn is it glorious. I've written a lot of fluff, and this chapter is going to end pretty rough too. I may end this soon, but I need to know if you guys want a sequel first. If you do, please oh please, check out the poll on my page and vote. I would appreciate it.
Undyne hadn't worn her armor in years, though she had kept it, and herself, in wonderful shape. Kitty was staying over at Frisk and Sans' house. The Royal Guardsmen knew what was coming. She didn't care.
The bastards that had kidnapped Kitty months ago were planning on taking, and killing, another monster child. Undyne was still their hero, their protector. She wouldn't let it happen. Grabbing her spear, she went to leave. It was dark outside, and Sans was in the kitchen.
"Where are you going?" Was all he asked. Undyne stared him down.
"You know exactly where I'm going." She stopped adjacent to him.
"Undyne, you can't leave her." Sans turned to face her. There was something in her eyes, and he knew he wouldn't be able to stop her. He also knew she wasn't coming back from this. "Kitty needs you." She grinned.
"I'll be back. Maybe as dust, but I'll be back." She said. He shook his head. "Kitty… She'll have you, and Frisk. If she wants to, she can even live with Papyrus and Mettaton in Hollywood." Undyne laid a gloved hand on Sans shoulder. He couldn't see the tears streaming from her eye. "Take care of my girl, Sans."
Undyne left the house. Sans watched as she left, but returned to his own house, lying to Frisk and Kitty, saying she just needed some time alone. She was having a rough night, since it was Alphys' birthday.
Striding through the town, the people who recognized the captain backed away. They could tell she was on a mission. Her helmet was removed, so she could make sure that she had found the right warehouse. Leaning beneath a window, Undyne stopped to listen.
"Look, I say we just kill the kid. Ransom is too risky, he's seen our faces." One man said. She managed to peek with her good eye. A little boy, who looked remarkably like Knight Knight, was tied to a chair. He was crying.
"We have to try ransom. This guard woman is pretty loaded. Besides, we kill him after we get the ransom, say he's alive, and get more." Another man explained. Eleven human men, four human woman. Fifteen bastards in all. This wasn't going to be an easy fight, but that's not what she had come for.
Undyne sank to the ground, and pulled out her favorite picture of her family. Kitty was five, and dressed in a pink, Kissy Cutie Mew Mew swimsuit. Alphys was holding her, even though Kitty desperately wanted to be in the water. Frisk was in the pool, splashing Papyrus, while Mettaton and Sans lounged in the sun. Toriel had her feet in the water, and Asgore was trying to coax Kitty in. Undyne had just fallen in the water, and she could only see her splayed legs. A friendly human had snapped this picture.
She held it tightly to her chest, adjusted her grip, and burst open the window.
Throwing her spear, whilst summoning more, Undyne shouted for the boy to run. Guns were firing at her, and she was blocking easily, until someone came at her with a blade. She froze, feeling her body disparate. She began to laugh. Eyes glowing, Undyne looked at the humans around her.
"You're going to have to try a little harder than that."
Determination flooded her as she became Undyne the Undying. She speared five more humans as they fired on her. They kept attacking. Yelling in frustration, she threw several off that tried to pile onto her.
Ducking, dodging, more and more spears made contact with humans. All of the women were dead in minutes. Undyne felt no guilt. They hurt Kitty, and they had planned to hurt another innocent monster. There was no need for guilt in this.
Their numbers were dwindling quickly, while Knight Knight's son had hidden behind some crates. Panting, she stared down the final human.
"The girl." She snapped. "Yellow skin, red hair, big eyes." He stared at her, terrified. She didn't notice him scooting backwards. "Her name is Kitty. That was my little girl you took, and because of that, you deserve to die." One more spear appeared in her hands. His hands jerked, and her spear raked across his chest, as it ended. She heard the gunshot, but she didn't feel it.
Undyne, the hero of the monsters, the captain of King Asgore's royal guard, was dust before she hit the ground.
Nobody needed to do a search for her. By three in the morning, the all-out war in the warehouse was televised. Undyne's final moments were broadcast for the world to see. Frisk kept Kitty away from the TV for the next few days. They needed Papyrus and Mettaton to be back.
"Sans, you knew she was going to do this." Frisk hissed. Kitty was in the living room, coloring and humming, talking every so often to Gaster.
"I couldn't stop her." He reminded his wife. Her swelling stomach wasn't very large yet, but it certainly was distracting. "I told her to come back. It's not my fault she didn't."
"I know." Frisk covered her face in her hands. "How do we tell Kitty? Undyne did exactly what Alphys did. She's never going to trust anyone."
Sans pulled Frisk into a hug, sighing. "I don't know. She's going to think we're lying. Papyrus is better at this kind of stuff."
"FRISK!" Papyrus threw the door open, scaring them apart. "Is it true?!" He searched her face. "Undyne-She- No!" Kitty came into the kitchen. Papyrus looked at his Goddaughter, and pulled her into a tight hug. "I am so sorry, Kitty."
Kitty struggled away from him. She looked up at everyone. Her glasses were askew from the hug. "Why are you sorry? Mom's coming home tonight. She- We're gonna watch Kissy Cutie Mew Mew!" Tears formed in her eyes. "Mom can't leave like Mommy did. It's not fair! It's not fair. It's not-"
She broke down into sobs. Mettaton quietly came into the house, while Papyrus gently pulled her into his arms.
The Sherriff arrived not long after, asking about Undyne's behavior. Papyrus and Kitty were inseparable. Neither of them wanted to believe that Undyne would start another civil war just to get revenge, but when Knight Knight showed up, expressing her thanks for her son's rescue, they understood. Papyrus did, at least.
"Ma'am, does this little girl have any other family?" He asked Frisk. Mettaton was sitting with Papyrus and Kitty. "Legally she's supposed to go to the next of kin." The man was kind, and had stated in the beginning he was fond of monsters.
"Just us." Frisk explained. Sans began trying to coax Kitty into eating something. "Papyrus is her godfather, but I don't know if she'll want to go to California. Her house is right next door."
"Well, we'll have to check the records, and make sure. She should be able to choose, but I don't know." He informed everyone he'd be back every few days, to check on Kitty until he knew for sure she had a choice.
Kitty did eventually eat, only because Papyrus offered to cook. Toriel came over, helping get Kitty's things out of her bedroom. They would clean out Undyne and Alphys' things, and sell the house. It was while Frisk, Mettaton and Toriel were packing Kitty's things a few days later that she asked a question the scared Sans.
"Uncle Sans, can I reset now?" She looked up at his shocked face, tears still streaming down her face. "I don't like this world. I miss my mommys." Papyrus looked to his brother. Sans pondered for a moment.
"N-…No. Your power to reset is still far too out of control, let along all of your other magic. I want to reset, but…it's just not a good idea." He explained. Every word made anger flush Kitty's face.
"Momma was right." She stood up. "You're a lazy heap of bones and I hate you!"
"Kitty!" Papyrus looked appalled. "Sans is right, there isn't anything we can-"
"You're supposed to be my Godfather! Why are you helping him? I thought you loved me!" She took off out the door, just as Frisk and Toriel were coming inside. Frisk landed in Mettaton's arms, but Toriel managed to catch Kitty.
"I hate you! I hate you Mommy! I hate you Momma! I hate you! I hate you…" She shook hard with sobs.
