Hello Fanfiction world. I've seen many good hero crossovers, but I decided to write one filled with many, many heroes from multiple series. If you see a series you do not like, don't tell me to not include said series and don't read if it bugs you so much. I'm gonna name the series (That I thought of so far) at the end of the chapter, but you might notice a hint to a series as you read.

Enjoy.

"Will you hurry up" said Conduit Bask.

Said members of the Flame Keeper's Circle silently nodded or saluted as they continued working on the cube in the center of the table, each side glowing a different color before shifting to another color. The other Flame Keeper's Circle members in the room, the Esoterica, were still making adjustments to the old Diagon base that Conduit Bask had discovered a week ago, along with the cube buried underneath it.

When the names Flame Keeper's Circle or Esoterica popped into people's head, all thoughts go to the villainous cult that worshiped the Diagon, a demonic entity that plagued the earth centuries ago. The Diagon and his army of Lucubra invaded the earth, killing many innocents and knights, with the only real opponent being a Knight named George, an Immortal man who has been alive for nearly 9 centuries. While George didn't fall at the grasp of Diagon, he'd only really obtained the power to banish the Diagon from the mortal dimension when Asmuth, a wise being of the Galvan people, offered the powerful (Yet not magical) sword Ascalon to George. Ascalon was a sword capable of making it's wielder a powerful being. George used Ascalon to carve out the Diagon's heart and banish the demon and it's Lucubra back to it's own dimension. Afterwards, George established a knighthood of warriors to counter future demonic and alien threats incase the another threat like Diagon ever came to earth, the Forever Knights. King George also had both Diagon's heart and Ascalon sealed away as further precaution.

Many centuries later, however, the Flame Keeper's Circle discovered the barely surviving Vilgax, an alien warlord, who in his giant squid form, mascaraed as the Diagon in order to gain power against his ultimate enemy: Ben Tennyson. Wielder of the Omnitrix and it's advanced upgrade the Ultimatrix, powerful objects enabling Ben to transform into alien species from all over the Universe and evolve them using the Ultimatrix.

At the same time, a fraction of the Forever Knights foolishly unleashed a Lucubra into the mortal realm, which became the warning signal for Old King George of the Diagon's return. In an attempt to make a stand against Diagon and his followers, George united all the fractions of the Forever Knights into one in order to combat Diagon.

Both groups actions brought Ben Tennyson and his team into the fray. Eventually, Vilgax gained the Diagon's heart and was transported into it's dimension as a servant of Diagon. King George regained both Ascalon and his youth, and overtime, went to war against Diagon and the Flame Keeper's Circle. While both the Forever Knights and Ben's team battle the FKC, the Diagon was released into the Earth once more, turning every being on earth except several people into Esotericas. In the Insuring battle, Diagon defeated the Ultimate form of Ben's strongest alien and killed King George. But Vilgax, who had no interest in being the Diagon's slave, used a device that absorbed energy on the Diagon. The Diagon was a being of pure energy, so all of Diagon was absorbed into Vilgax, making the alien tyrant a being of near absolute power. With the Diagon's power, Vilgax then focused his power on killing Ben Tennyson. But Ben, wielding the power of Ascalon, fought Vilgax while absorbing the Diagon's energy into Ascalon. Vilgax was eventually rendered powerless and beaten. And Ascalon was handed over back to it's creator Asmuth.

With the Diagon gone and Earth returned to normal, the Flame Keeper's Circle were broken, scattered, and labeled criminals. While the Plumbers destroyed all the Flame Keeper's Circles bases and technology, it was S.H.I.E.L.D. that led the manhunt on the Cult, backed up by the Avengers and the Justice League. It became clear to the Cult that neither Superhero team could be beaten by their broken order, especially with the Kryptonian and the Gamma-Monster. Only Conduit Bask's group remained.

Conduit Bask was the successor of Conduit Edwards, leader of the Cult during the Diagon crisis who was killed by King George. Conduit Bask was not the direct successor however, Conduit Bask's predecessors falling at the hands of S.H.I.E.L.D. and the Plumbers. All that was left of Bask's group were only thirty Esoterica and a handful of scientist.

"Sir" said the chief scientist "As I told you when we discovered the cube, the object is alien in origin and incredibly complex to operate. We're not even sure if this item is even related to Diagon"

"The item we discovered under Diagon's temple isn't an item of Diagon?" said Bask mockingly/crossly "Might I remind that this order cannot afford anymore screw ups. Our lives only have any real purpose if we can continue Diagon's will, which is impossible if the Plumbers get to us"

"But sir, we don't even know what the purpose of this item is. We were able to analyze the object and discover that it does emit a strange energy, but it's not recognizable by any of our technology, even our alien technology can comprehend what it could be"

"If it is the Diagon's energy, then it is our mission to use this to unseal the Diagon and continue his reign on earth" said Bask, who assumed that Diagon was merely resealed like last time.

"But-"

BO0OM!

The entire room shook as the booming echo filled the room.

"Sir" shouted a FKC member at a monitor "Three Plumber ships have surrounded the temple!"

"What!" shouted Bask.

Before Bask could compose himself and order his men, something crashed through the roof and landed down on the floor.

Said something was a tall figure donning the armor of a Plumber Magister, covering it's entire body except for it's green mouth and sinister eyes. The Magister immediately decked the nearest Esoterica before spin kicking two more. Three Esotericas quickly used their dimension traveling ability to disappear in thin air and reappear behind the Magister to cut him down. But the Magister quickly shifted around and slashed all three Esotericas on their necks, all three falling dead.

"Fight back! For the glory of Diagon!" shouted Conduit Bask.

For the remaining Esotericas stayed where they were, shifting their focus to Bask, the Magister, and the three dead Esotericas on the floor.

"Cowards! You're all a disgrace to the Flame Keeper's Circle and Diagon itself!" shouted Bask.

"You should stop talking before you join the brave one's on the ground" said the Magister as he removed his helmet, revealing a bald, green head with pointed ears and long antenna.

Just then, several Plumber soldiers lowered themselves down into the chamber and aimed their weapons.

"It always surprises me how you Namekians can be so violent when prodded Noor" said another Magister as he casually walked towards the Namekian. The man was old yet well built.

"My race has nothing to do with my job Magister Friecs" said Noor. "With this the Flame Keeper's Circle is finished"

"Bite your tongue alien" said Bask "Even if every member of our order is dead, the Diagon will rise again"

"Jeez, what a clueless bunch these guys are" said Friecs.

"We're not gonna kill any man who surrenders peacefully" said Noor "But remember, your cult nearly caused near slavery for humanity" Noor cracked his knuckles menacingly "So no one would miss you if you died"

...

"For the glory of Diagon!" shouted Bask as he disappeared in air.

Friecs stayed silent as he heard a powerful thrusting noise to his left and lazily turned his head to see Conduit Bask lying on the floor, foam seething out of his mouth as Noor stood over him.

"I didn't kill him" said Noor "Just stunned him"

"Yeah, well-" Friecs turned to the rest of the Cult "Any takers?"

The only response were all members dropping to their knees and raising their hands over their heads.

"Take em boys"

.

"I tell ya" said Friecs "I thought their would be a little more resistance when we came here"

"It's best this way" said Noor as he scanned the chambers while Plumber officers searched and dismantled every corner of the room. "The Flame Keeper's Circle is now as of this moment disbanded"

"I understand how this is important, but your the only one that did anything"

"The men we took today were scared men in a losing war. The real fighters of that group were killed or arrested by the Avengers or the League"

"Man what odd groups the earth's seen" said Friecs as put a cigar in his mouth "It's already been six years huh"

"Yes, it has indeed been six years since the Majin Buu ordeal" said Noor "And now earth is filled with odd beings"

"Yeah well I rather earth wasn't so special in my opinion" said Friecs "So I hear your going home?"

"I am indeed taking a leave of absence to visit New Namek" said Noor "It's about time I see what New Namek is like"

"I guess I'll have to reassign myself for awhile" said Friecs "Wonder if Max of Patelliday need a partner for awhile?"

"Magister Tennyson and Magister Patelliday wouldn't mind your company" said the Namekian "Though Magister Tennyson might still tease about how long it took for you to gain a Magister status"

"I'd only obtained my Magister status because my boss was killed by that Osmosian Aggregor"

"Magister Prior Gilhil's death has nothing to do with your promotion. There had been talk about giving you Magister status before the Andromeda kidnappings"

"Yeah well, it still doesn't sit right with me" said Friecs "I tell ya, you sound like me wife"

"I do not know if that's a compliment or an insult" said Noor.

"Magister Noor. Magister Friecs" said a Plumber officer as he approached the two.

"What is it?" asked Friecs.

"While clearing out the Esoterica files, we found that they were attempting to obtain information about this item" said the Officer as he handed Noor the glowing cube.

"What is it?" asked Noor.

"According to the files we looked up, it was believed to be an item related to Diagon"

"Is it?"

"No, the item is Galvan tech in origin" said the officer "But it's not like any Galvan tech in the Plumber database"

"So what?" asked Friecs "Were the Esonuts trying to work Galvan tech?"

"No" said Noor as he observed each side of the glowing cube "Were looking at a different brand of Galvan tech"

"What do you mean sir?" asked the officer.

"Most if not all Galvan tech is basically in our database, so even if this was attempts at altering Galvan technology, it would still be in the Plumber database" Noor looked as each side of the cube glowed "But the fact that it's not in our database means that it's unknown Galvan tech"

"Unknown Galvan tech? When was the last time something like that appeared?" asked Friecs.

"Since the Omnitrix appeared on Earth" said the officer.

"... So what does this mean?" asked Friecs.

"Well unless Asmuth hid one of his projects in a Diagon temple, we're looking at a new threat"

"How bad we talking?"

Noor stared at the cube "I can feel it. A power surge of energy surrounding this simple cube. No one being that has threatened the Earth before could possibly compare to this thing"

Noor suddenly widen his eyes, he turned the cube around and saw that on one of the cube's side, a black dot was forming on the center of the cube's face as it expanded towards the edge of the cube's side, as if someone was coloring a square from the center. When the dark part made contact with Noor's skin, he dropped it in pain as the cube fell to the floor, the cube's first side fully black as the dark color started spreading to the other sides of the cube. As the cube blacken, blue steam started forming off the cube.

"Noor?" asked Friecs. Noor turned to the officer.

"Get every Plumber out of here and contact Magister Tennyson! NOW!" shouted Noor.

"Y-yes sir!" saluted the officer as he ran towards the door.

"Noor, what is going on?" asked Friecs.

"I'm sorry my friend, but if this is something we can prevent" the cube blackening to it's last face as blue steam boiled off the object "I'll gladly take the chance"

"...If we die because of this, Tennyson's gonna have our hides"

As the the cube became pitch black, it started unfolding as if it was origami. As the squares started unfolding, the blue steam started whistling as the room became filled with a blue fog. Noor and Friecs quickly shielded their eyes as they could no longer see anything but the color blue, Noor having to jam his thumbs into his ears, for the powerful whistling was killing his sensitive Namekian ears.

When it seemed like the whistling was gonna make Noor deaf, it started dying down. Noor took in heavy breaths as he opened his eyes. He saw that the room was starting to clear out. Noor quickly got into a fighting stance as Friecs pulled out a blaster.

When the mist cleared, a being was standing right where Noor dropped the cube.

The creature was whitish blue all over it's body, fading markings all over it's body on a closer inspection. It's wings, if they were wings, were oddly formed, looking like butterfly wings made out of symbols. The creature's eyes were completely white as it stared to Noor to Friecs to it's own hands.

Noor and Friecs stayed completely still, neither dropping their stance as the creature wiggled it's fingers infront of it's face.

"I'm free" said the creature, a hallow echo surrounding it's voice. "I can no longer be contained"

Noor saw that the creature was sentient so he attempted to talk to it "Don't move. We're not here to hurt you, but we will defend ourselves"

The creature tilted it's head towards the side as it looked at Noor.

"Now this is confusing" said the entity "I see a Namekian in high tech armor threatening me, yet I also see a human in matching armor pointing an also high tech weapon at me. Am I on Namek or Earth?"

"...T-this is earth" said Friecs, finally speaking up.

"Earth" the creature looked towards the ceiling as the word sunk into it's head "So this was my bed for several centuries apparently" It smiled "I'm surprise that humans and Namekians have advanced this far in life"

"It seems you were contained for many years" said Noor "Let us take you back to a Plumber base"

"Plumber?!" said the creature in shock as it's white eyes widen "Oh so the Plumbers are still around"

"You know of the Plumbers?" asked Friecs.

"Oh yes, secret police of the galaxy, defenders of defenses, and my enemies" said the creature nonchalantly.

The creature suddenly instantly appeared infront of Noor and pierced it's arm straight through his chest. Both Noor and Friecs widen their eyes in pure shock as Noor coughed up purple blood.

"And any friends of the Galvans" it jerked it's arm further in "Is an enemy of mine"

The creature then thrusted it's arm forward, pushing Noor off it's arm and onto the floor.

"Sorry about that" said the thing as it turned to Friecs, who's eyes were bloodshot as he stared at Noor's body "I'm sort of pissed at the Galvans and I needed an outlet"

"AAAHH!" shouted Friecs as he fired his blaster at the creature, the energy bouncing off the creature as it looked at the frenzied human.

"Humans sure have changed since they were discovered" said the creature as it ignored the blaster fire "I remember when humans ran when beings like me appear before them. Then again"

It narrowed it's eyes.

"There are no beings like me"

BOOOOOOOOOOOOOOOOM!

A huge explosion engulfed the entire temple, the mountain it rested upon, and the three Plumber jets unlucky enough to not escape. When the smoke cleared, all that was left of the once tall mountain was a massive crater, the creature was sitting Indian style, it's face supported by it's palm as it inspected the unfolded cube in it's other hand.

"So this was what she was working on" said the creature with venom in it's echoic voice "She was recreating Majin Buu's seal pod. That's an impressive feat, especially since this is purely tech" What was left of the cube disintegrated as it's remains sprinkled to the floor "Level 20 Tech, her second best creation. But that changes nothing"

The creature spread it's exotic wings as it took off to the sky.

"If your still hiding from Azmuth I know where to find" the creature burst off towards the sky, space itself it's road.

"You once called me a being of the very stars themselves, and the stars see all. I will find you and make you pay for twisting my fate. Not even Asmuth will be able to protect you"

The creature continued racing forward, the Earth far behind as it kept zooming further and further away.

"Prepare Zennith!"

"Tabuu is reborn"

.

So that was the first chapter of what I hope to be a long and exciting story. With so many interesting stories in fiction, it's just so tempting bring them all together and fighting evil. If you played Fusionfall, you would know what I mean.

As you can imagine, setting so many stories in one world requires a lot a planning, thinking, and adjusting. So if you notice something that conflicts with something, please go easy on me and remember, this is just Fanfiction. Also please keep the comments clean and positive.

I'll try to explain how both the Justice League and the Avengers exist in the same universe and how it works with the other series next chapter.

This story will contain swearing, nudity, and slight gore. Basically a fair equivalent to your basic anime.

For those who don't know Tabuu is the Final Boss in the Super Smash Bros Brawl video game. Tabuu in the game was a one time, out of the blue, mysterious being that I thought would be the perfect villain for this story. And yes, I know Tabuu doesn't talk or anything like that in the game, the Tabuu in this story has an OCish backstory fitting into the story.

And now for the series that I'm using for my story. Now before I list them off, let it be noted that these are the series I've chosen to work with. Maybe I'll just use one character from said series, maybe I'll list something that won't appear right away into the story, maybe a series will have a one-time interaction with the main group. I don't know, haven't gotten that far yet. But these are the series I've chosen to use and I would like it if my choices are respected. If you don't like a story I listed and it interferes with reading, your free to not read. If you see a series you don't know yet have no intention of watching and still continue to read, I'll try to explain the story so you can continue reading without tilting your head in confusion. Also I try to keep the characters in character when I write a story, so don't bash me if a character seems OCish. And now, my selected series:

But before you leave a review, read the rest of this.

Like I said before, all these stories aren't gonna collide into one big something. These are the series that I see that could work with my story. The main hero group is going to be made from a select pick of characters to form their group. The rest of the characters on this list will associate and work with my select group from time to time, kind of like how the Avengers work with the Fantastic Four and the X-men. And I can see a scenario where the group aren't always this one big group (Some of them doing their own thing while something's going on. Some of them are still in school after all). If I ever do bring all these series together, it'll probably be those pesky final bosses.

I can also understand if no one remembers some of the shows I listed, especially the shows that don't air anymore.

Also if you saw Tom and Jerry on this list, there just mascots, so don't flip out. I think we can all agree that with all the people those two met, a superhero family wouldn't be there weirdest owners.

I'm also looking forward to seeing how people react to seeing most of these solo heroes working with other heroes of different elements.

And also the villains. Superhero team ups must be so annoying for them.

The Avengers, Justice League, and the Dragon Team are sort of the senior heroes to my select group, so they'll be teaming up most of the time.

And now to conclude this Author's note, which in my opinion has gone on way too long. Hopefully they aren't as long as this one.

REVIEW LIKE HELL!
