-Unnamed Mountain Range, New World-

The New World, it is one that was visited by outsiders before. The First was the Six Great Gods worshiped by the Slane Theocracy and then the Eight Greedy Kings both of whom ushered in both prosperity and destruction to humanity in this world. However, they are all actually players of an MMO by the name of Yggdrasil from Earth who were transported there through unknown means. The recent arrival to the New World is Momonga, the leader of the Guild Ainz Oaal Gown, and alongside him is his Guild base that is the Great Tomb of Nazarick. He also renamed himself to be Ainz Ooal Gown as well after arriving in the New World.

This brings a new player to the landscape of the New World however a new one would show up and try to take over the New World just like the Eight Greed Kings. Unfortunately, this new player, Gary Stupid, will only make things complicated more than anything else.

Speaking of which, Gary Stupid has just arrived to the New World but instead of being transported the same way the previous players of Yggdrasil did, he did so from his own Earth.

"So this is the New World, huh?" Gary said. "It looks so good! And perfect for taking over for myself!"

He was smiling smugly.

"BUT! I need a place to stay before I do so. And an army!" Gary said. He then held up his hand and in front of him, a Floating Fortress appeared, looking like a generic evil fortress with spikes and everything.

"I shall call this! The Fortress of Gary!" The man said.

He then entered the place via the creation of a portal to the throne room. Which looks EXACTLY like the one from the Great Tomb of Nazarick.

"This looks perfect!" Gary said with a grin.

It didn't. It looked like a ripoff.

Gary was marveling at the architecture of the throne room and how it suits his taste.

As if the ripoff was the better thing compared to the original one, which it wasn't. He then sat on the ripoff throne of the World Item, Throne of Kings. He then smiled smugly at sitting on the chair.

'Now then time to call in my Floor Guardians!' Gary thought to himself.

-10 minutes later-

After calling forth the Floor Guardians, Gary was sitting on his throne bored out of his mind. He was getting impatient and is wondering when they'll show up.

Then he got his wish as a pair of vampires flew in. They are the First Floor Guardians, Remilia Scarlet & Flandre Scarlet, both of whom are loli vampires.

Gary grinned and thought: 'So fucking cute!'

Then Floor Guardians of 2 & 3 showed up. Who are Esdeath & Tanya von Degurechaff, respectively. The former is a well-stacked woman while the other is also a loli.

"Why are there so many brats in here?" Esdeath asked, looking at Remilia and Flandre.

"I'll have you know I'm 500 years old!" The Elder vampire said.

"You tell her big sis!" Flandre said.

"Whatever," Esdeath said.

Then the Floor Guardians of the 4, 5, and 6 floors. They are Master Xehanort, yet another human who is leading Organization XIII, who are known to comprise nobodies, and the Heartless. He is the guardian of Floor 6.

Davoth, the Dark Lord, and the Supreme Ruler of Hell who is the Guardian of Floor 5. He is there in his red armor.

And finally, the Khan Maykr, who is the Supreme Ruler of Urdaak who is the Guardian of Floor 4. She was floating above the ground and arrived via teleportation.

"Well, looks like everyone is here. How lovely," Gary said.

He couldn't see Davoth glaring at him through the helmet of his armor.

"Anyway, the reason I brought you all here is that I have a plan!" Gary said.

"Oh, and what will this plan be exactly?" Xehanort said. He wasn't expecting much from his "leader".

"I want to take over the world!" Gary said boldly.

Many just stared blankly at him. He failed to notice.

"How will you even do that?" Esdeath asked rhetorically.

"By attacking nearby places! And taking them as my own!" Gary exclaimed.

"Don't we need to need to know what this world has before doing so?" Tanya asked, starting to get a little annoyed at Gary.

"Of course not!" Gary said.

Tanya facepalmed.

'Oh my goodness! Is our leader an idiot?!' Tanya thought angrily in her mind.

'Though he'll be useful as a pawn to achieve my goals,' the Khan Maykr thought to herself.

Esdeath was glaring ice-cold daggers at him while Remilia and Flandre were dumbfounded by his idiocy.

'He'll definitely be useful as a pawn of sorts,' Davoth thought to himself.

Xehanort was grinning because he was already thinking of a plan to use Gary for his own gains. Gary just thought that Xehanort agreed with him that it was a brilliant plan.

Now the Floor Guardians were in two teams.

On one side is the group that wants to use Gary for their own gains.

On the other is the group who just doesn't like Gary in general.

And Gary had no idea about it.

'They probably think my idea is good!' Gary thought to himself.

'This has got to be the most idiotic person I had the unprivilege of meeting in my entire life. No. Of all time,' Esdeath thought to herself. 'I mean really! Does he actually know the rules of engagement and first contact?! I might be sadistic but I know that information is required first and foremost when it comes to war!'

She was barely able to contain her disdain.

"Anyways! It doesn't matter what army would be sent at me! It will just show my might and power when they go down like flies! So get to it!" Gary said as he waved his hand dramatically.

'What an idiot!' Tanya thought to herself.

"I'm going to sleep! Bye!" Gary said as he created a portal and entered it, leaving the room.

He then left the room, leaving the Floor Guardians to discuss themselves.

Safe to say it none of them like the guy.

"Why do we work for him, Big Sis?" Flandre asked.

"I don't know...but I don't like him so much," Remilia said.

"I agree," Tanya said.

"He's worthless," Esdeath said. "I would have loved to torture him like the piece of garbage that he is!"

"I don't care, he's going to be a perfect pawn for me to use to my heart's content," Xehanort said.

"Suit yourself," Remilia said.

"I doubt he's even good at combat, either," Davoth said. "Nor would I expect him to be good at ruling. He doesn't seem to know what he should even be doing."

"Well, either way, he will play right into my fingers and be my puppet as I become the puppet master," the Khan Maykr said.

"I agree with you. Though what is your name? Actually, I just realized we never introduced ourselves. My name is Xehanort if you are wondering," the human said.

"I am known by many names...Davoth, the Supreme Leader of Hell, the Dark Lord, the Father, it matters not. Either of those titles you can call me is fine," the Leader of Hell said.

"I'm the Khan Maykr, the Dark Lord already knows me, but to you, I am the Supreme Leader of Urdaak, besides the Father of course," the Khan Maykr said.

"General Esdeath," Esdeath said. "That is my name and also my ranking among my army."

"Remilia Scarlet, Daughter of Vlad Tepes!" The Elder Vampire said with an arrogant smile.

"She's not! I'm Flandre Scarlet, her little sister!" The Younger Vampire said.

"Major Tanya von Degurechaff!" The Young Girl said. The rest of those in the room were surprised and interested by what she just said.

"A major at your age? Interesting," the Dark Lord said.

"Mhhhmmm. I never thought I would see this before," Xehanort said.

"A child soldier and a high ranking one at that. I see me and you will probably get along just fine. I can FEEL IT," Esdeath said.

Tanya grinned from that compliment.

"Me too General. Me too…" Tanya said.

-Throne Room, Great Tomb of Nazarick-

Momonga, or rather now named Ainz, was in his throne room. He has called a meeting with his Floor Guardians: Albedo, Shalltear Bloodfallen, Demiurge, Aura Bella Fiora, Mare Bello Fiore, and Cocytus. Victim and Gargantua are the only two Floor Guardians not participating in this meeting.

"Lord. Ainz. Why. Have. You. Called. Us. Here." Cocytus said.

"Because a strange floating fortress has been spotted, and Demiurge has taken noticed of suspicious activities taking place in there," Ainz said.

"Like want Lord Ainz?" Shalltear said.

"Demiurge? Explain your findings to them," Ainz ordered.

"I have discovered that there have been some attacks on several villages that came from the floating fortress itself. I can identify some of their species, ranging from lesser vampire minions, ice constructs, and surprisingly humans working with vampires, too," Demiurge said.

"That is rather strange," Aura said.

"What do these...humans wear or look like? And those vampires too?" Ainz said.

"Well for one the humans seem to wear soldier uniforms unfamiliar to me. Like they wear helmets and wield weapons similar to CZ2I28 Delta albeit different compared to her. They also had an odd symbol on their arms which appears to be some sort of cross. A swastika, I think they call it. And I heard that some of the vampires were seen dressed the same way," Demiurge said.

'NAZIS?! How did they get here?!' Ainz thought to himself in surprise. 'More importantly why are there Nazi Vampires too?!'

"I see. This will require further observation," the Overlord said.

"Indeed," Demiurge said.

"If this new arrival does pose a threat to the Great Tomb of Nazerick, then we will retaliate swiftly before they can do so," Ainz said.

"However I believe that this structure could of have been formed by another person that originated from Yggdrasil, milord," Demiurge said.

'Wait would this mean I will meet another player?!' Ainz thought to himself though the green aura seemed to calm him down from the shock.

"It is a possibility I took into consideration, which is why we will start with observing before we act," the overlord said.

"A wise decision from you, as usual, Lord Ainz," Albedo said.

"We'll see what type of people that this person has in store though there is a possibility that he might have floor guardians as well," Ainz said.

"Well my scouts have told me that it has multiple floors, so this a possibility," Demiurge said.

"I kind of hope they're strong instead of the weaklings of this world," Shalltear said.

"But for now let's see how things unfold..." Ainz said.

A/n: So what you just saw here is basically my play on the term Gary Stu. He'll be the "main character" of this series. Or should I say "Big Bad" but in reality, he would be considered a wannabe main bad for this fic and also VERY incompetent and also idiotic when it comes to ruling or being a leader to those he is leading. Plus unlike the rest of the Gary Stus he is not instantly good at doing

And yes as you have seen here there are several DIFFERENT people from different works. I.e Master Xehanort from Kingdom Hearts and the Khan Maykr from Doom. They'll show up as major characters...and they won't be the only ones to be there…
