In Agartha, Doctor Monty was setting up his Christmas lights on the house. Agartha, while usually sunny, had grey clouds and had snow everywhere.

"Fuck!" Doctor Monty yelled angrily as he got tangled by the cords of the Christmas lights.

"Monty?" Asked Ludvig Maxis, coming outside to see if he was alright."Are you okay?"

"I've been better." He muttered. He sighed."Hey, are the guests here yet?" He asked the german scientist.

Maxis shook his head."No, not yet. But are you sure inviting them here is a good idea?"

Monty nodded as he took of the cords."Maxis, you worry too much. I just wanted to have at least one Christmas with some creatures from the Multiverse. It's time I start revealing myself more."

"I thought you weren't supposed to interfere with certain things?" Maxis said.

"Come on, Maxis." Monty said to him."I can show myself at least once. I did it to Richtofen and his friends, remember?"

"I also remember you killing me but this story is just a fanfic so it's not canon so...hey, aren't you Santa Claus? I remember you saying that you read people's Christmas lists."

"Well, yes, I just read them but thats it. I let Santa do all the work." Monty said.

All across the multiverse, everybody was singing a Christmas song as they went through the portal Monty had opened for them.

"It's shaping up to be a wonderful holiday," Anakin Skywalker and Obi-Wan Kenobi sang as they were about to cut down a tree with their lightsabers."Not your normal average every day."

They cut down the tree and it fell.

"Sounds like someone killed my old Serennian tree," Count Dooku sang along, looking at the two Jedi."Kenobi, Anakin, why'd you do this to me?"

"The world feels like it's been lovelier." Starlight Glimmer and Trixie Lulamoon sang and dance.

"Go away before I harm you bodily!" Chrysalis sang, annoyed.

"This Hearths Warming...Christmas feels like the very first Christmas to me!" They sang.

"There'll shopping," Sang Nathan Drake.

"Decorating," Sang Lando Calrissian

"And plenty of snow," Sang Jon Snow.

"Hey, Grif, who's that under the mistletoe?" Dick Simmons asked Dexter Grif, pointing at Sarge who was under the mistletoe.

"What, who, me? Would you look at the time, I should go!" Sarge quickly left the base.

"People seem a bit more brotherly." Jacen Solo sang.

"Here's a special something to you from me." Anakin Solo sang, giving his brother some fruitcake. Jacen grabbed the fruitcake and threw it in the trash.

"Even all the trash and Christmas itself smell sweetly." Han Solo sang."Because Christmas feels like the very first Christmas to me."

Ultimis Richtofen then started to dance very weirdly.

Richtofen then kicked open the door to the Shadowman's house."What do you want, can't you see that I'm busy?" The Shadowman said.

"Step outside, we got something for you to see." Ultimis Richtofen and Ultimis Nikolai sang.

"Richtofen, take this stuff down immediately!" The Shadowman said, seeing Christmas decoration on the Apothicon pyramid.

"Chestnuts roasting and burns in the third degrees!" Ned Stark sang as the Targaryens burned people.

Everyone in the multiverse was now heading to Agartha."Because Christmas feels like the very first Christmas to me!" They sang but stopped when they all saw each other.

"Wait, who the hell are you guys?" Laverinus Tucker asked, looking at everybody.

"Hello, everyone!" Said Doctor Monty."I invited you here to the center of the Multiverse: Agartha!"

...

"What?" Rainbow Dash asked, confused."What's Agartha?"

"The place you are in right now!" Primis Richtofen said.

"Well, who are you?" Asked Princess Leia.

"Oh shit! I completely forgot to introduce myself. I'm Doctor Monty." He smiled.
