Just to help a bit.

(M/N) = Hazbin Hotel (M/N)

Ignika = Bionicle (M/N)

Don't own the art of the videos. They belong to their respective creators.

Enjoy!

Christmas music could be heard as the theater was filled to the brim with Christmas decorations.

"A little to the left!"

Zero said as Moxxie and Millie moved a wall decoration.

"Perfect!"

Zero nodded his head.

Strolling around, he could see many people in their own groups.

Charlie could be seen adding her own personal touch to a couple of Christmas trees.

Setting them on fire.

"That's my girl!"

Lucifer shouted proudly, causing his daughter to blush all shades of red.

"DAD!"

Lilith laughed at her daughter's evident embarrassment.

Regret in her mind as she started pondering the choices she had made.

'Was it really worth it leaving them?'

She thought to herself.

Doubting herself for once.

(I truly hope they don't make her out to be a bad mom when she appears in Hazbin Hotel. That would be a rather cheap move to do)

Vaggie shook her head in mild amusement.

Angel Dust could be seen flirting with Husker...and failing as the demon cat was more interested in the high quality booze the Gods had to offer.

(And Dust wasn't crazy to try with Alastor, after the Radio Demon nearly made good on his promise if AD touched him again without permission)

Blitzo was busy trying to avoid Stolas while at the same time having father daughter bonding moments with Loona.

Octavia was facepalming as Stella was trying to kill Stolas.

(M/N) was currently being pressed up against a wall as Carmilla gave him the bedroom eyes.

Her daughters, Clara and Odette, sweatdropping at how thirsty their mom was for the teen.

'Well at least her love is intense love and not yandere love.'

They thought to themselves.

In another side the Batfamily was having a 'healthy' Christmas festive.

If you didn't include a certain somebody trying to shoot them, or someone else trying to stab them.

Alfred was being Alfred.

Somehow cleaning even the hardest to reach places that mere mortals could not.

Yeah...he chose not to question it.

The girls of Azur Lane were busy chatting and setting up their own Christmas decorations.

Well...almost everyone. Enterprise was still in the 'we are just weapons' phase of her life.

Still a hard thing to get through.

'Imagine when they find out what the (M/N) of their world is hiding.'

Zero chuckled to himself.

Knowing that they will be in for the surprise of their life not just because their soon to be new Commander is a teen, but also did something rather stupid as a kid.

...Which ironically unintentionally screwed up the Sirens plans back then.

Amagi could be seen reprimanding her sisters. Both for stupidly allying with the Sirens to try to bring her back, but also because they nearly burned down one of the Christmas after trying to put fire fox spirits on them.

BONK!

Bonking them on the head...again.

Zero shook his head at his sister-in-law's foolishness.

Looking to another spot, he can see some of the Union members talking with their RODK counterparts.

(I.e. the smart ones and those who realized how the errors of their ways, and those that were never bullies in the first place.)

Union Adam was talking to RODK Adam after asking Zero if he could speak to him.

(Both were a little confused about the weird guy with horns crying when he saw them)

The God wasn't surprised.

Of course, Adam would want to know why his counterpart took a different path than the one Union Adam was currently on.

RODK Overhaul was for some reason, decked out as a Santa Claus (minus the beard) with RODK Eri decorating him with Christmas lights.

And could be seen visibly uncomfortable with Midnight and Mount Lady flirting.

'This is TRUE hell.'

Chisaki Kai thought to himself.

This was the TRUE karma that came for him.

Trying to fend off sexy ladies that were trying to get into his pants!

Did his actions really warranted this kind of punishment!?

The bullies/shameless perverts were crying tears of blood due to receiving coal.

(Like Santa was going to reward you for bad behavior. Or more accurate, for crimes against humanity behavior)

It was even more sad and humiliating for them because others like Adam, Lute, and some villains and demons got what they wanted for Christmas!

Even the Vees!

Now THAT is saying something about how Santa sees them on his nice and naughty list.

Yuki was busy whistling as she stared at some Santa outfits.

"And they say I'm the dirty one."

Sukuna deadpanned, reading her host mind.

"Shut up, bitch." Yuki deadpanned. "Or do you want me to tell everyone about your fantasies of my boyfriend?"

"..."

"Thought so."

"Oh?"

Gojo eyebrows rose behind his blindfold.

"Do tell."

"...Die."

Sukuna roared as she lunged at the troll master.

Who dodged elegantly like a ballerina.

The others sweatdropping.

"So that's what happened in your world?"

Bionicle Gudao asked his RODK and FGO counterparts.

While his sister was busy chatting with her counterpart.

The Toa were busy setting up things and adding their own flare.

While Ignika.

*Giggle!*

Was busy babysitting a bunch of kids using his hair as toy.

(He can grow out his hair with his powers. And it's styled like the Grand Lancer hair style)

And burying themselves with it.

While RODK (M/N) was busy having his hair braided by some of the other kids.

Adele and Macarios conversing with their RODK counterparts, interested in how their lives are like.

Patxi grumbled as he avoided the crazies that were into 'questionable' things concerning guys like him.

And also wondering why that hellhound, Loona he believes, was looking at him like that.

He wasn't interested in dating/courting at the moment!

"No."

Denki deadpanned.

"Aw, come on!"

Izumi pouted as her boyfriend refused to put on the Santa suit.

"Not happening."

Denki deadpanned.

"Pleasssseee?"

Izumi asked, cutely.

"Let me think-no."

"Damn it!"

Doom Slayer could be seen giving his grandchildren weapons of mass destruction.

'I say over the top, but it's not.'

Zero sweatdropped.

*TUG* *TUG*

Looking down, he saw his oldest son who was still a child due to how his and his son's mother species worked. So, he was still a kid even after eons of existing with the mentality of a child.

His son was kind of a black blob like figure. And by that he meant that his son had a humanoid figure but didn't have a real appearance just a blank black canvass. He had a blue outline on him to make out his body and to show that he has hair.

(Think Truth and Father real form from FMA. That's kind of what he looks like. Just more adorable.)

(...Alright, I took inspiration from Bendy the Bunny avatar drawing as well.)

"Yes, Shadow?"

Zero looked into his son's blue eyes.

The only thing that existed on his otherwise formless body.

Lifting his arms up, he made an 'up, up' gesture.

Chuckling, he picked his son up and into his arms.

"You enjoying yourself?"

He asked.

Shadow nodded as he rested his head against his father's chest. Purring as he felt content and at peace.

"Zero."

Ei voice grabbed the two attentions as they turned to look at their wife (Zero)/stepmother (Shadow).

Ei smiled, wearing a cute, sexy, yet not overly revealing, Santa outfit.

"Damn!" Zero whistled, his nose slightly bleeding from how well it fitted her. "Looking good, babe!"

Giggling, Ei replied.

"Thanks dear. Now I have –"

"NO."

"DANG IT!"

Ei pouted, yet another year of trying to get her husband into a Santa suit failed.

Arknights Theresa simply laughed.

'Why bother when we know it's virtually impossible?'

Shadow giggled as Zero walked away with him.

"Remind me again, headmaster." Snape crossed his arms in annoyance. "Why do I have to do this?"

His dark robes were now Christmas colors much to the poor man annoyance.

And to the amusement of Sirius and Remus.

"Because it's Christmas, my boy!"

Dumbledore cheerfully said, his robes sporting a more festive look for the holidays.

Harry and the others putting up their own Christmas decorations.

"Bloody hell!" Ron grumbled. "Why couldn't we just use magic for this?"

"Because using magic is lazy and cheap."

Harry, Hermione, and Ginny all said at the same time.

"Gah! Betrayed by my own friends and sister!"

Ron mocked hurt.

Out of the corner of his eyes, he saw an alternate version of Lappland dragging a certain someone.

"NO! NO!"

The man screamed.

"I want to live!"

*BANG*

The door closes.

*BANG!*

The door opens!

"I WANT TO LIVE!!"

The man gave one last scream as he was dragged back in with the door closing.

'...'

"...Wait."

Zero realized something.

"Where the heck did Tempest go this time?"

Activating his 'eagle eyes' he noticed a trail that led...

...To a closet?

Blinking, he opened the door to find a knocked out Tempest on the ground with his legs up against the wall.

And in his hands...

*Smack!*

Zero facepalmed himself.

"I warned him that Le-Koro eggnog was the strongest of all the villages/cities eggnogs. Even for Gods, it could knock us out."

Shadow blinked.

Sighing, he called Tempest wives to pull him out of the closet and wake up him.

"Wyatt!"

Will and Echo were shouting trying to find their toddler son who was nowhere to be seen.

...Again.

'Okay, how the heck can they freaking lose their kid so many times?'

Zero was super confused about that.

'You'd think they put a bell on him or something.'

Sighing, he looked around. Only to see that Wyatt along with his cousin playing with Ignika hair and tangling themselves up with it. Laughing and giggling as they wrapped themselves with it.

Ignika humming a tune he learned from an old friend that seems to have a soothing effect on the hyperactive children.

The Kaiju Girls were busy interacting with their RODK counterparts, especially Godzilla and Ghidorah.

'No fair!' KG Godzilla thought to herself. 'Why is my counterpart so damn hot!?'

While KG Godzilla was definitely hot and thick, her counterpart looked hot, thick, and a complete femme fatale!

'Her breasts might not be as big as mine, but she makes up for it with her toned, thick body!'

KG Godzilla thought in despair.

While RODK Godzilla was wondering why her counterpart was having a mental breakdown.

"So, you are literally three people in one body?"

KG Ghidorah asked, a puzzling expression on her face as she tickled San face. The dragon head purring at the sensation.

"Yes." The Alien Kaiju confirmed, staring at her counterpart. "It gives an extra intelligence boost as well as making plans."

"...Can I have them?"

"NO"

With the HI3 group.

"So..." Kiana uneasily spoke to her HOTV self. "You're me from the future."

"Indeed." HOTV Kiana stoically smiled. "Talk about a blast from the past."

...Indeed.

"And you." Kiana turned to the young male besides her.

(Adam)

(Okay! A little bit of a backstory on Adam! As you can see Ignika (M/N) and HoTV Kiana is his parents in this timeline. But as we all know he is a young man in APHO, which is not that far into the future after the main storyline...I think. Now, how is he old enough to be in the events of APHO? Ever heard of or played Fire Emblem Fates? There's a mechanic called Deeprealms where time moves faster than in the outside world. That's basically what happens here.)

(And yes, he has cat ears and a tail)

"Are my son that I will eventually have in the future?"

"Yes." Adam nodded. "Nice to meet you, little mom."

"LITTLE!?" Kiana shouted. "BOI! I know my future self did not raise you to be this disrespectful!"

"...Did you forget how we were when it came to dad?" HOTV Kiana sweatdropped. "I'm pretty sure we would raise him like that. Plus, have you seen (M/N)?"

"He's not in our world, yet."

HI3 Theresa answered, trying hard not to let her jealously show that she is still single.

"Ah."

"Sooo, Adam." Kiana smiled, a disturbing glint in her eyes. "Are there any girls that caught your interests?"

!?

Uh-oh...

"...UHHH."

Here her future self and future son suddenly found the ceiling interesting.

"What?" Himeko blinked, as she took a swing of some good alcohol. "What's wrong?"

"Well..."

"It would be us."

Appearing from behind, revealed

(APHO Raiden Mei)

(APHO Bronya Zaychik)

"WHHAAATTTT!?"

The HI3 group shouted in pure shock.

"Uh, I can explain."

Adam weakly said.

Whir!

"No need to explain son." Kiana 'calmly' said with a pissed off expression. "Mama gotta beat down some bitches right now."

Yelling, she lunged at the future versions of her friends.

"Die you perverts!"

"Kiana! We're sorry!"

"Bronya is not."

"Die you ara ara bitches!"

"MOM NO!"

Adam and the others rush to stop the pissed off Tuna rampage.

"Wait!"

Valentino shouted.

"Let me join! I want to try out these new stylish guns Santa gave me!!"

He joined the chase.

Vox and Velvette just looked in amusement with the female Overlord recording this.

Master Splinter and Antauri were busy meditating peacefully with the chaos around them.

"Hey!"

A new voice called out to him.

Turning he saw.

"We're here and we bear gifts!"

Jair, along with Bino, Demo and several other gods entering the theater.

"..."

Zero quickly wrapped a confused Jair in ropes before kicking him out the door.

A sign saying:

NO THEATER DESTROYERS ALLOWED!

"HEY!" Jair had waterfall tears in his eyes. "I promise I won't burn your theater down!"

"...Even I doubt that."

Bino sweatdropped.

"You should let him in."

Comix sighed, his wife Artemis shaking her head in amusement.

"Otherwise, he's not going to stop."

...

*Clack!*

"If you open a rift and end up bringing the Old Ones in here, I'm going to rip your ass off and mount it over the fireplace!"

"CAPISH!?!"

"Aye-aye captain!"

Jair saluted rushing in.

"Dodge!"

And punching Will, Bino, and a now awake Tempest in the face.

"OW!" "WHAT THE HELL!?" "SERIOUSLY JAIR!?"

"You bitches still can't dodge!"

"So sad."

Piccolo shook his head.

As the Saiyans and Beerus ate to their hearts content.

"Talk about fun, right bestie!?"

Demo wrapped an arm around Zero.

"..."

"...I'm not your friend you psycho."

"Aww!" Demo pouted. "Don't be like that!"

*Twitch*

Zero resisted the urge to punch the Australian Author God in the face. Especially with Shadow in his arms.

Which was kind of pointless considering he currently had a blackhole on his head at the moment.

The TMNT turtles and the Robot monkeys decorating at insane speeds. Showing off their training and ninja skills.

Ch'rell (Utrom Shredder in case one of you have never seen TMNT 2003) sipping some damn good hot chocolate with Palpatine and Ivan Ooze.

The Avengers and Justice League having ornaments on their suits.

Cain and Ava deciding to 'celebrate' in their own special way in one of the private rooms.

(Someone getting some more siblings)

Shinachiku using the Uzumaki Chains to keep his rambunctious siblings and friends from throwing high-powered jutsus all over the place, hanging them in the air.

Asuka happily chatting with him about a place to go for one of their future dates.

The Genshin Impact cast chatting with the rest of the groups in the theater.

(I'm not going to write a Christmas special for that book, too lazy and I'm surprised I'm even writing this chapter. So, for this chapter, they're mingling with the rest of the cast)

All in all, it looked to be a good Christmas so far.

Fwoosh!

"My ass is on fire!"

Deadpool screamed as he ran across the theater.

As Spyro (M/N) (From Demo Union book) chased after the dangerously unhinged nutjob.

"Come back here and say that to my face you pervert!"

"Eiiieeeee!!!"

"...Idiot."

(M/N) sighed, as he put Shadow down, who walked away to the other kids, and threw Demo off of him.

"Wheeew!"

Demo shouted as he flew right onto the PJO group and sending them flying.

"AAHH!!" "Only in America!" "Wheew!" "*Wilhelm scream*"

"Morons."

Zero groaned.

"Dodge!"

Jair as he flew at Zero.

Who tilted his head and Jair flew right past him.

And into Will, Tempest, and Bino again...who were for some reason behind him.

*CRASH!*

https://youtu.be/El_hlnHnxDw

A bowling knockout sound could be heard as he flew at them.

Turning his head, he saw the gods flying up and back to the ground as a bunch of shocked bowling pins.

"...*Snort*!"

Zero laughed as he continued his stroll.

"LALALALALLAL-LA-LAH!"

Lorem and her friends and family were spending the day with cheers as they laughed and sang like maniacs.

Gospel could be seen wrapping himself up in Ignika hair. Using it as a blanket as well.

The Fate series group could be seen celebrating their own versions of the holidays.

(Different cultures most likely have their own holidays this time of the year)

The Arknights group smiling and milling about as Kal'tsit sipped her coffee. While Silence and Saria tried to stop Ifrit from burning down the place.

"You've outdid yourself, son."

Doom Slayer walked up to Zero, smiling behind his helmet.

"Thanks dad."

Zero said.

"Where's mom?"

"...Well." Doom Slayer looked to the side.

"...Oh, you got to be kidding. REALLY!?"

"Hey!" Doom Slayer protested. "You said you wanted to be a big brother!"

"But to the point that she can't walk for what? Another year!?"

"Hey! That was an accident!" Doom Slayer protested. "I haven't gotten laid in like what? A billion years? A trillion years?"

"You old as fuck, old man!"

"I'm not old, you brat!"

Doom Slayer grabbed Zero in a headlock and began giving him a noogie.

"Ow! Ow! Quit it old man!"

Zero yelled as he stomped his feet on his dad armored foot.

"YEOUCH!

Doom Slayer shouted as he let go.

...

https://youtu.be/kpnW68Q8ltc

Suddenly, heavy metal music began playing as Doom Slayer looked at his son.

"OH! I think it's time for our annual father-son bonding time."

"Bring it on, you old geezer."

With that the father-son duo charged as betting tables were set up and popcorn was hot and ready for some real life action.

"Just another day in our lives, huh father?"

Atreus shook his head as he watched his godbrother and godfather duke it out as usual.

"Boi." Kratos just said. "Never a dull moment."

"Indeed." Mimir smiled.

As he sipped his drink.

Where it went, who knows?

"Dear!"

Ei shouted.

"Don't forget!"

"Huh!? ...OH!"

Zero suddenly stopped as everyone, including the other universal Gods looked to the screen.

"Merry Christmas to all! And to all, a good night!"

Done.

Have a good day/night!

And a Happy Merry Christmas (or happy holidays if you celebrate something else) to all! And to all, a good night!
