Deep within space fortress Oblivion, Emperor Marcus, leader of the Hybrids, is concocting a most devious and secretive plan to start the Second Eternal War. The problem is, the heroes and villains of the various dimensions are too strong to face without taking any casualties, and the forces of light and darkness are patiently waiting for any move he takes. In order for his legions ensure the elimination all opposition from the two forces; he must devise a plan to sow distrust between the various champions of good and evil. Suddenly, a figure enters his room, dress with a black shirt, hat, cape, jeans, and a blade covered in the flames of darkness.

"Ah Cerberus, I have need of you son." said Emperor Marcus.

"What is it you need father?" said Cerberus, fifth son of the Emperor.

"We must prepare invitations for our guest for the Greatest Tournament EVER! (Evil laughing,)" said Marcus.

Meanwhile, at the Nexus (a part of space connecting several dimensions) of the Marvel, Capcom and DC universes, the heroes and villains are preparing for the upcoming battle.

"All right, everybody status report." said Captain America

"Defensive networks are up and running Cap" said Iron Man from the New York radar hub

"Everybody is ready for Metal head and his freaks," said Frank West positioned on the streets filled with roadblocks and other fortifications

"Strike teams are ready to target and eliminate high value targets," said by Batman positioned on top of a skyscraper

On the other side of the frontline, the forces of evil prepare for their invasion of New York.

"Are our troops ready for the invasion?" said by Dr. Doom overlooking the battlefield.

"My vampire kin are ready to sweep away the rubble my lord," said by the vampire lord Deacon Frost.

"My robotic machines can obliterate the enemy within seconds!" said by M. Bison.

"My assassins are prepared to deal the deadly blow," said by Ra's al Ghul standing near his assassins surveying the heroes for any high value targets.

"Great, commence the invasion!" said Dr. Doom.

The heroes stare in awe and fear as the endless horde marches towards them. Even though the heroes are confident that they would be victorious, for everyone on their side there is dozens and dozens more of villains fighting for evil. The forces of evil charges through the battlefield and are within a mile from the city when a great light enveloped everyone.

"ARGGH!" said by everyone and then disappeared from the face of the earth.

All over the dimensions, heroes, villains and other people who are destined for greatness have disappeared all for a grand scheme of manipulation and deception!

The champions awaken in the middle of a grand coliseum surrounded by people they know and do not know.

"What is this, Where has the warp sent us?" said by a Chaos Marine.

"Argh, it seems we're somewhere unknown bob!" said by an awaken Wolverine.

"Why are we here X?" said by a confused Axl.

"Don't know, guess you, Zero, and me are lost in this strange place" said by Megaman X.

"It seems like we are at some coliseum. Perhaps this is a tournament for which we are to fight." said by The Emperor (Final Fantasy)

"Whoa looks like we've got company Cap!" said by Spiderman.

(Captain America helps Batman stands up) "Thanks" said Batman

"No problem, looks like you're one of us." said by Captain America.

On top of a floating platform, Emperor Marcus gives his speech to the contenders: "Greetings warriors, I am Emperor Marcus, I have brought you all here to participate in this tournament!" (The crowd of hybrids cheers the warriors)

"Why should we participate in this tournament?" said by Liu Kang.

"Your homelands are slowly being rip apart by multi-dimensional warfare! As you continue to travel and fight throughout between each of the worlds, the rifts within reality become stronger and eventually destroy everything! I offer a solution to this problem. In exchange for participating for the coming battles, I will fix the damage myself. Besides, those who proven themselves victorious in my arena will be handsomely rewarded!" said by the emperor.

"I will not participate in some tournament only to died as someone's pawn!" said by Dr. Doom with disdain.

"Do not worry, I assure all of you that no champion would die in this coliseum! We have prepared hologram simulation that feels like the real thing, except you don't die!" said by the emperor.

Questions keep coming and the Emperor keeps answering, while alliances between the two forces are secretly being formed:

Wesker along with his minions, HUNK, Nemesis, and Krauser joined the dark god Chaos (Final Fantasy) and his congregation of evil heroes along with Nightmare (Soul Caliber) and his minions, Voldo and Trish. Along with this alliance, the various evil organizations of the three dimensions joined as well.

Justice League, Marvel's Ultimate Alliance, along with the heroes of Capcom all made an alliance.

While the participants prepare for the first match, the hybrids are covertly working underground. A bustling military base operating by two sides and conducting a special mission. One side is filled with people on seats, wearing helmets connected to the structure, whose purpose are to collect data from the participants and their various home worlds. The other side is full of teleportation machines used to shipped hybrid weapons to the various factions that sow the universe with strife and conflict.

With a barrage of cannon fire, the first match is announce!

"Here is the kicker, for our first match all participants will battle it out on an all out brawl! You can work with others, but the more participants survive the brawl the smaller the reward! For the first match, to my right are the heroes, the people who chose the path of righteousness!" said by the Emperor.

Several of the viewers, that are from the same dimensions as the participants cheered the heroes. On the other side, the crowd is antagonistic and yelled and cursed the warriors.

"To my left, are the villains, the hegemony of evil doers that seek to rule all!" said by the Emperor as he raises his left hand.

They too received both cheers and curses from the onlookers.

"And finally, in the middle are the misfits! From bad boys to mercenaries to loners and others with no allegiance to either light and dark! Will they stand together or turn on each other!" said by Marcus.

"Look guys, we're on TV!" said by Deadpool.

"Participants have thirty minutes 'till the match starts!"

"Why am I grouped with you guys anyway!" said by Zero as he is classified as a misfit.

"Cheer up Zero, you, me and Dante over there would make a great team! I could see it clearly now, The Three Desperados for Hire!" said by Deadpool.

"Speaking of which, why don't you two work with me hunting demons! The girls are taking leave so we can have a blast at my home!" said by Dante.

The three Desperados talk throughout the thirty minutes. What do they talk about? Obviously, its about the drinks, the ladies, and the money.

Going supersonic while running in circles. "Whoa, looks like I'm not the speedster in town!" said by the Flash as he describes Sonic the Hedgehog.

"You bet, this is only my daily routine!" said by Sonic.

"Flash, Sonic stop running around!" said by Iron Man.

Over the evil side, the evil forces talk about their plans for the match and for universal domination until…

"I CAN'T TAKE IT ANYMORE!" screams the Khrone Berserker as he raised his chain axe and charges at the enemy.

The Khrone Berserker targets a yellow rat, a Pikachu. His thoughts are only that of killing that rat for the BLOOD GOD! He's breathing rapidly increases as he charges towards the Pikachu. He jumps and raises his chain axes ready to deliver the killing blow and…

Everything turns gray as a person covered in black garments appears at the center. He looks similar to Emperor Marcus, but while the emperor is dress in dark garments with hints and marks of orange color this individual has cyan after light markings in his garments and mask.

(Deceased) Emperor Sirius (of the First Hybrid Race): "Will the bloodthirsty killer claim first blood for evil or does the pathetic excuse of a rat survives the onslaught! Find out next time!
