Author's Notes:

Yeah, this was just mae in like a hour. Enjoy or don't, I don't really care or expect you to.

“Ready for hallo-I mean, Night Mare night?” Raz asked his two little daughters, one pony and one human. He didn’t dress up… mostly because he didn’t see the point, his countless motes of power and his countless charges allowing him to become whatever he wanted whenever he wanted anyway.

“Hold on daddy, I’m almost done putting my costume on!” Chara called out from her room, followed by various sounds. Basically whatever sound was made whenever a loony toons character constructed something.

Soon, Chara came out to Raz deadpanning at her door. When he saw what she was wearing he facepalmed. Chara wore a paper-mache skeleton head with enchanted eyes, one went blank and the other flashed yellow and blue. She also wore a blue hoodie, white t-shirt, basketball shorts, and pink slippers. Three guesses as to who she was dressed as, and the first two don’t count.

“What? Just the thought of sans having a ‘hard mode’ is scary as hell!” She said defensively, making Raz chuckle.

He grinned widely. “Yeah, wouldn’t want to get ‘boned’,” He said with a chuckle. Chara deadpanned at him, not getting the innuendo.

“I’m gonna have to deal with the skeleton puns all night aren’t I?” She questioned, receiving a shrug and a wink from her father. At that moment, Crystal Mercy came down with a ‘serious’ (read:adorable) face. She had makeup on to make her fur look pale, make her look like she had a pink blush… and a spare set of Charas clothes on, a toy knife in hand.

“Really? I’m the scariest thing in the world to you?” Chara deadpanned to her adoptive sister.

“O-only when y-you’re mad,” The sister stuttered.

Chara puffed her chest up a little in pride, ego a little boosted. “Well of course I am,” She said with a smile, patting Fri-I mean Crystal Mercy’s head. “That’s why your big sister is feared by our enemies.

Crystal deadpanned at her. “I think they’re more scared of Daddy,” She said to her sister. Chara was about to argue… before remembering the time the dragons attacked and were decimated, making her sagely nod in agreement.

“Yeah, they’re lucky he wasn’t a saiyan then… he might have gone super,” Chara said, a chill going down her spine at the thought. Daddy had enough power boost in him thank you very much.

With that the group of them went out trick or treating. Whenever they went to a house, they saw two bowls of candy… and they each got half of the second. At every house. Raz had to make them more bags just to hold all of the sugary goodness.

After they had gone to all the houses in the crystal empire, Chara sighed. “Daddy, can we go to Canterlot and do this? We’re getting too much…” She said as she looked down at the twelve bags of candy she alone had.

“Alright,” Raz said with a nod. He waved a hand, teleporting the current candy to the castle while giving the two new, empty bags. And with that they teleported to Canterlot… but it was empty, quiet.

Raz frowned, he couldn’t even sense Celestia anywhere near here. Something was up… looking around, he found the source of the absence of ponies. They were little black creatures, with two yellow eyes, and no heart to speak of. “Well, isn’t this wonderful,” Raz dryly said.

“Okay… one of two things happened. Somehow, I’m tripping balls, or the Heartless came for a visit…” Chara said with a sigh. “Quite frankly I don’t know which is worse.”

Raz shrugged. Snapping his fingers, a keyblade appeared in his hand. It looked like it was ever shifting, features of the blade changing too fast for Chara or Crystal to detect. Kinda like their daddy’s powerset.

Snapping his fingers, Crystal was sent home where she was safe. He reached his senses out, finding heartless only in the city. He also gave Chara a keyblade...

It would mimic all Undertale attacks perfectly… in looks, anyway. Power is a thing she’d need to provide. Swinging his own blade, he cut through the heartless like they were nothing, blade lengthening quickly to unreal lengths and cutting them down before they could react.

Snapping his finger again, he used one of his more reality warping powers to lock all future heartless out. For now there was heartless to kill in here and he didn’t want them getting reinforcements.

Something Chara seemed to agree with because she was slashing her sword randomly, launching random UT attacks at the creatures which were… surprisingly effective. This was what the two did for around an hour, taking out all of the heartless.

After the heartless were finally cleared, and they were on the edge of the city, Raz snapped reality relatively back to normal, with the addition of the block from others entering that was triple enforced, Celestia arrived.

“Thank you, for saving my little ponies,” The mare said with a relieved look on her face. Raz just grunted a little, annoyed she’d even left them in the first place. Very irresponsible.

“Whatever, c’mon sweetie we’re goin home,” Raz said as he grabbed her shoulder.

Chara nodded. She looked about to say something, but a quick mental conversation between her and her father had stopped that right in it’s tracks. Though Chara did pout with crossed arms over it, Raz was not starting an international incident over cake. That was just dumb.

With that the two teleported home, and the rest of the night was normal… well, as normal as you can get considering the circumstances.
