Author's note:

So, here it is, the actual Multiverse: Infinity War. And I hope you enjoy one of the biggest crossovers I've ever done yet anywhere!

A little observation: due to the large quantity of characters in the cast, some characters will have roles "shattered" among them. For example, while Sonic and NiGHTS will mostly be Captain America and Iron Man respectively, bits of Thor's role will be scattered for NiGHTS, Meta Knight and Kris, and Steven Universe and Cream the Rabbit will shaare Peter Parker's role together once they meet. I hope you guys like it despite this little detail. =)

Also, please be respectful if you don't follow Female!NiGHTS, Female!Frisk, Female!Chara and Male!Kris headcanons.

"Listen to me, my creations. Listen to me, pitful Nightopians. You have the honor of being helped by the one who Waits Behind the Wall, the Hivemind of Chaos, Zalgo. This is not pain like you all might be thinking...it's salvation."

The owner of the voice making this monologue was Wizeman, god of the dark side of the Night Dimension. He was levitating atop terrified Nightopians and unconscious Nightopians alike, and among those unconscious, tiny and innocent creatures was Owl, the old informant in the Dream Gate, who just looked at the Wicked and the four other creatures that brought this chaos to being.

"Soon, justice will be proven and you'll be our stairs. Even if we die, we should smile...because we all, are Followers of Zalgo.", Wizeman concluded.

Wizeman's chief enforcer, Reala, stood in the middle of the chaos apprehensive. Not because of the Nightopians and the old bird, but because of the figure responsible for "enslaving" his master. After all, the tall (but still dwarfed by Wizeman), demonic creature with seven mouths, horns and snake-like eyes, managed to quickly subdue Reala's rebellious sister NiGHTS with minimum effort, and was now holding her by the chest.

"I understand how it's like to lose. To feel so desperately you're right, yet to fail in the end.", Zalgo said. His voice was deep and echoed, but he held the tone of a adult talking to a child with it. "It's terrifying, and transforms us into weaklings. And for what, I ask you? Dread it...run from it...destiny arrives no matter what. And now, it came. Or should I say...I came.", he concluded, as he lifted his hand, revealing it to be a closed fist of long, sharp fingers covered with a shining Infinity Gauntlet. It already had a purple stone resting in one of it's slots, and it shined.

"...you're a real speaker...", NiGHTS weakly snarked.

"Your loyalty to your "master", or your sister's head.", Zalgo said with a calm but devilish smile, using the purple-clothed jester as bait. "Maybe you prefer the former."

"Of course.", Reala confirmed, crossing his arms with a smile...that faded once he saw the Hivemind of Chaos using the purple stone to inflict brutal pain on his sister. "Alright, ENOUGH!", Reala yelled, with a worry he never had for his sister since a long while.

"We don't have whatever you're searching for!", NiGHTS stated after gulping most of the pain, trying to make Zalgo give up. However, she was proven otherwise when Reala removed his mask, revealing that behind the pink gem that rested on it, there wa a faint, blue glow. "You...really are the worst, Reala."

"I'm sorry, my dear sister. But this had to be hidden from you.", Reala calmly stated, as he professionally floated towards Zalgo, who dropped away NiGHTS like simple trash.

"I used to think I was a more respectable god, but you...deserve my bow.", Wizeman stated, as Reala's mask's pink gem was taken out, revealing a micro dimension with a blue glow. Zalgo digged his fingers in the mask's hole to pull out a blue gem, shining like ice, or the daytime's sky.

Once Zalgo inserted the blue gem on the slot, it let out a small pulse of energy that didn't faze the demonic being at all.

"There are two more easy stones scattered on the multiverse.", Zalgo said. "Find them, my followers, and bring them to me on my home dimension."

"Lord, we will not fail you.", Mary, a tiny blonde paiting girl said, as she, the spider-like being Beldam, criminal catgirl Uramiko and Wizeman bowed in respect for the Hivemind of Chaos.

Suddenly, the moment was interrupted by NiGHTS, who gained enough strenght to try and kick off Zalgo's back, a effort that proved itself fruitless and only served to get her knocked by claws, back to the ground.

"Excuse me, but I'd personally like to follow you as well.", Reala suddenly stated. "I have experience on being someone's second-in-command."

"If you like to think failure is experience...", Zalgo snarked.

"In anyway, or anyhow...", Reala said, as NiGHTS looked in horror over what was about to happen, denying a possibility of what her Nightmaren brother could be trying to do. "I, Reala, chief enforcer of Wizeman the Wicked, one of the...strongest. Nightmarens...to ever exist, I swear for you my new, unmatchable loyalty."

Reala swiftly shapeshifted one of his hands into a knife, which he used to try and stab Zalgo in his chest's top mouth, but failed because of the blue stone, which kept his hand paralyzed. Despite knowing doing this would be a suicide trick, Reala couldn't help the shock that rushed through him.

"Unmatchable?", Zalgo chuckled over the word choosen by Reala. "You shouldn't have said that."

Despite not having a visible neck, Reala was nevertheless lifted up from it and began to choke from lack of air, getting even paler than he already was, as NiGHTS helplessy watched from the ground. Even struggling, Reala couldn't escape.

"You...won't be a god...no matter what.", Reala harsly choked those words out of his throat before having his "neck" snapped.

NiGHTS screamed a large "No!" over seeing her fellow first level Nightmaren's dying and being dropped to her knees by his killer.

"No tragedic revenge's anymore.", Zalgo non-chalantly said.

Afterwards, the Hivemind of Chaos closed his gauntlet fist, creating a portal with the blue stone which he and his new comrades used to get into a new part of the multiverse, leaving NiGHTS to grieve over Reala. The two fought and fought in the past ever since NiGHTS' rebelled from Wizeman's tyranic rule, but they were still siblings...

"Hooh no! This is terrible!", Owl finally said, regaining his strenght to fly as he looked at the grieving NiGHTS. "Seems I have no choice but to send you to warn and help the others."

"Wait...wh...", NiGHTS was about to ask, wondering how Owl quickly knew what to do, before collapsing for sure with the pain she had to sustain.

Without saying a word, Owl touched the gem in his vest, opening a purple portal which sucked the purple jester in. He could only hope that this new evil threatening more than one world could be destroyed.

NiGHTS went like a comet through a plane full of titanic-sized bubbles of varying colors, containing stars, galaxies and planets within'. As her unconscious form slowed down, she began to aim for sure on a bubble of a light green color. As she entered inside it, consciousness slowly returned to her, as she got up to meet a bunch of beings, some looking like normal humans and others like completely different beings, staring at her in confusion.

"Zalgo is coming...", NiGHTS slowly but steadily said, as she got up holding up one of her arms. "He's coming."

"...who?", a teenager, blonde girl with peach-colored heart blushes asked after a awkward silence.
