Chapter I: Into x Another x World

Author's Note: The story takes place after Batman's ending in the game "Mortal Kombat vs DC Universe", and everyone's ending on the DC Universe side will happen but just not right away... Eventually some Mortal Kombat characters may appear. In the game, the Watchtower is named the "U.N. Oribital Space Station", so in this Fanfic, it will be referred to as such.

Concerned that other universes might once again invade Earth, Batman created an autonomous global security system to monitor any temporal breaches. His system, OMAC (Otherworld Monitor and Auto-Containment), is designed to detect, and trap invaders from alternate universes. OMAC has already discovered a breach in Metropolis…

October 11, 14:24 EST

Seven OMACs hastily headed toward one location: Metropolis. The OMACs had detected a universal breach similar in energy frequency to that of what the six of the original seven members of the Justice League had encountered just two years before, during the World Merge Crisis.

Metropolis was one of the largest and wealthiest cities on the planet. During the day time was when most of the villains operated. Which in turn, made the day time the time when Superman was out on patrol.

Metropolis was still recovering from the World Merge Crisis as well the earlier invasion lead by Darkseid and with the help of Lex Luthor. The city's structures are still, if not more war torn since Darkseid's Apokoliptian invasion, if not more due the World Merge Crisis, and other battles between Superman and other villains who were intent on destroying the city and doing anything to achieve their goals.

Downtown Metropolis

Spider-Man, an iconic hero from another universe. Recognized by many due to his trademark form-fitting spandex bodysuit, which from the waist down was blue, except for mid-calf boots with a black web pattern on a red background. From the waist up, the fabric was a red-and-black web pattern, except for his back, sides, and insides of his upper arms, which are blue. There was a large red spider outline on his back, and a smaller black spider emblem on his chest. The mask has white one-way mirror type lenses rimmed with black.

"Where am I?!" The masked hero asked himself, as he looked around, and didn't recognize anything.

Seven OMACs descended down to the ground near Spider-Man.

"UNIVERSAL BREACH!" Several of the OMACs exclaimed.

"Universal breach?! What is this about?!" Spider-Man replied.


Spider-Man felt a tingling sensation on the base of his skull, which he called his "Spider-Sense". His Spider-Sense warned him of an immediate attack by an OMAC.

One OMAC rushed toward Spider-Man and it tried to punch him, but Spider-Man dodged it by back-flipping out of the way.

Spider-Man jumped into the air, and shot a line of a synthetic substance, which highly resembled a spider-web from his patented web-shooters; both were designs of his own that also followed his personal theme. The web line stuck to a nearby skyscraper, then he swung away from the OMACs.

He swung from one building to the next, repeating the process several times over.


The OMACs started to chase Spider-Man throughout Metropolis.

"Stop following me!" The web-slinger exclaimed.

Elsewhere in Metropolis

Superman was one of the most iconic heroes in the entire DC Universe. Recognized by his iconic blue uniform with his famous red and yellow "S" shield on his chest, his red trunks over the blue tights on the lower half of his costume, a yellow belt, red boots and a red cape. He was the hero that all of Metropolis looked up to and depended on.

He was several kilometres away on the other side of Metropolis, but his superhuman hearing allowed him to listen to the echo of Spider-Man's words, as if he had shouted them directly in the Kryptonian's ear.

'Huh?… Something is up.' Superman thought to himself.

Superman started making his way toward the disturbance, still keeping a vigilant eye on the city as he made his way.

Spider-Man continued to swing away from the OMACs. He swung up onto the side of the nearest skyscraper, and used his unique power of wall-crawling to climb the skyscraper. He stopped and turned away from the skyscraper. His back stuck to the building behind him.

One OMAC locked onto Spider-Man and started to charge its laser. It fired a moment later at Spider-Man, as the superhero jumped toward the OMAC, but he narrowly dodged the beam. It broke through the windows barely a second after, and it left a huge gaping hole in the skyscraper.

"Hey! Watch where you're pointing that thing! There could be innocent people inside!" Spider-Man yelled. "Obviously they're not as dashingly handsome as I am but they're still worth saving!" He added as he fell toward the ground.

Spider-Man raised his left hand and shot a web line out of his wrist-mounted web-shooter and it stuck to the left foot of one of the OMACs. He tugged on the web line and used it like an elastic band, and it flung him up to and behind the OMAC. Then the superhero shot another synthetic web line and it stuck to the back of the OMAC, and again he tugged on it and used it like an elastic band, flinging himself onto the back of the OMAC, and used his adhesive abilities to stick to the back of the OMAC.

An OMAC charged its laser, then locked onto Spider-Man and shot it's laser.

He waited until the last possible second, then Spider-Man jumped off of the OMAC, and the other OMAC's laser hit the OMAC Spider-Man jumped off of, and it completely destroyed the top half of the OMAC, and the lower half fell to the ground.

"WOOHOO! Got one!" Spider-Man exclaimed as he himself also fell toward the ground.

Spider-Man shot a web line and it stuck to the nearby skyscraper, then he used the web line like an elastic and flung himself onto the side of the skyscraper, and he stuck to it using his adhesive abilities. He turned around and faced the OMACs with his back still sticking to the skyscraper.

"Huh?" Spider-Man said in confusion, as he saw a red and blue blur in the sky.

"What is that? Is it a bird? A plane?… It's!…" Spider-Man thought to himself.

Superman descended down to Spider-Man's level in the sky and then hovered, directly facing him.

'It's just a geek in a skin tight costume…. Reminds me of myself, actually…!' Spider-Man thought to himself.

"Power down OMACs. Justice League member. Designation, number one." Superman said to all of the OMACs.

"RECOGNIZED. SUPERMAN OF THE JUSTICE LEAGUE. POWERING DOWN." Every OMAC in the vicinity powered down, leaving only enough power to sustain flight.

"You seem to be causing a lot of trouble around here…" Superman said to Spider-Man.

"You think I'm the one who… Oh, no! You have it all wrong. These toasters did all the damage." Spider-Man replied defensively.

"Who are you?" Superman asked.

"I'm your friendly neighbourhood Spider-Man, of course!" He replied.

"I'm sorry. I've never heard of you."

"That makes us even then, 'cause I've never heard of you either."

Superman stared at the wall-crawler, slightly confused. How could someone on the planet Earth not know about the Man of Steel? It just didn't make sense to him.

"Where are you from? Are you from Earth?"

Spider-Man stared back at Superman equally confused. He as well wondered how he had never heard of him, or even recognized him.

"Yes, I'm from Earth. And if you've never heard of me, then you must not be. And to further answer your question, I honestly have no idea where I am."

"You are in the city of Metropolis. My name is Superman. Why were the OMACs attacking you? What have you done?" The Man of Steel asked.

"The heck I know! I don't even remember how I got here. All I know, is that these "OMACs" as you call it, started attacking me for no reason!" Spider-Man replied, explaining himself to Superman.

"Well, there is one way that I can know if you're telling the truth or not." Superman reached out telepathically to J'onn J'onzz. "J'onn, can you hear me?" Superman asked telepathically.

J'onn J'onzz, AKA: The Martian Manhunter known as the greatest telepath on Earth, was known for being the last Martian in the universe. In his "Superhero form" He was a humanoid green alien creature, somewhat resembling a bald green skinned Human, with a red "X" shaped sash across his body, a red belt, blue trunks, blue boots and a blue cape to match.

J'onn, at this time was on the U.N. Orbital Space Station, about to take a sip of hot coffee as he did nearly every morning.

J'onn, almost putting his lips on the edge of the cup, almost about to take his first or second sip of his coffee, suddenly stopped and placed the coffee filled cup down on the table in front of him.

"Yes, Superman. I hear you loud and clear." The Martian replied telepathically.

"I have a job for you." Superman thought to himself, which J'onn picked up telepathically.

"What is it?"

"There's a superhuman being with me. He calls himself Spider-Man. I need you to read his mind to see if he's on our side." Superman said telepathically to Martian Manhunter.

"Spider-Man? Never heard of him... Tell me when you're ready and I will teleport you both up here immediately."

"Well… Sorry to leave you like this, but I have to go and be somewhere that isn't here." Spider-Man said.

"We're ready." Superman said out loud, and J'onn heard it telepathically.

"Wait I-" Spider-Man said anxiously.

Just then Superman, and Spider-Man instantly transported from Metropolis.

They arrived at the U.N. Orbital Space Station Teleportation Room, which shocked and awed the young hero in the spandex costume. The Space Station was 22,300 miles above Earth's surface.

Due to the World Merge Crisis two years ago, the Justice League had come to the conclusion that the original seven could not maintain world order by themselves.

The U.N. Orbital Space Station was redesigned and received several new rooms and additions. The Justice League has expanded and with it, several new members have joined the new and improved Justice League.

"Incredible. Are these fully functioning teleportation devices?" The web-slinger asked. "But y'know, you coulda just said "Beam us up, Scotty" and I would've known what you were doing…!" He added.

"Uh… Right. Anyway, welcome to the U.N. Orbital Station."

It was unlike any other place he had ever seen before. "Wow. This sure beats the heck out of the Avenger's Mansion!" Spider-Man accidentally exclaimed out loud, which surprised and confused the last son of Krypton.

Superman thought about asking what this "Avenger's Mansion" he spoke of was, but ultimately decided against it, until he could find out more about this "Spider-Man" and where exactly it was that he had come from.

"Right this way, Spider-Man." Superman said, pointing to another room in the Space Station.

The two heroes started walking toward the other room which had a sign above the door that read "Conference Room."

They stopped barely three feet away from the door, not yet opening it.

"Behind these doors, I'll introduce you to one of my fellow team mates in the Justice League." Superman said.

"Sure… I'm looking forward to meeting him." Spider-Man said with a hint of sarcasm in his voice.

Superman placed his right hand on a hand print scanner, directly beside the door.

"Recognized. Designation, number one." A computer was heard saying throughout the Teleportation Room.

'This security system reminds me of the S.H.I.E.L.D Helicarrier.' Spider-Man thought to himself.

The Conference Room door opened and the two heroes walked inside.

The Conference Room was the most magnificent of all the rooms in the station. Inside there was a large table, with seven chairs, each representing the original Justice League founding members with their respective insignias on the back.

A large window was adjacent to the large table, which had an amazing view of Earth's moon, the Earth itself, the Sun, and the countless other stars within the Milky Way Galaxy.

Seeing that the Space Station was in Earth's orbit barely surprised Spider-Man, in fact, he half expected it due to the fact that they had to teleport to get there.

Only two members of the original seven were in the room: Superman, and the Martian Manhunter.

"Are we ready to begin?" Martian Manhunter asked.

"Ready to begin what?" Spider-Man replied, answering the Martian's question with another question.

"The mind reading process…" J'onn looked toward Superman. "You did not inform him?"

"Well, no, I…" Superman quickly thought of something to say. "I was going to wait until we got here before I asked him."

"Well, if you want to get that personal, then you have to buy me dinner first!" Spider-Man said. He took a short pause before he spoke again. "As long as you don't use that trick to discover my secret identity or my personal life, I'm all for it."

"You have my word." Martian Manhunter said with a seriousness in his voice, enough for Spider-Man to trust him for this one time.

Martian Manhunter placed his hands, on either side of Spider-Man's head. The Martian's fingers hovered about an inch away from his head.

"Stay still. This will only take a moment."

The Martian's orange eyes started to glow brightly as he read Spider-Man's mind.

It only took a few moments to complete. Martian Manhunter now knew nearly everything that he had to. However, he failed to learn the exact reason how Spider-Man came here.

Martian Manhunter expressed a sigh of relief. "Good news. He is not a villain. So he is not a threat to our universe…. In fact, he is not even from this universe at all."

"What?!" Superman and Spider-Man immediately asked simultaneously.

"Allow me elaborate..."

"I'm listening." The young hero said impatiently.

"The memories I encountered while I read his mind… They are the memories of a man from a different reality… A reality where there is no Darkseid, no Flash, or Green Lantern. There isn't even a Justice League… Including ourselves. Instead, there are different heroes and villains populating his Earth." The Martian said to the confused heroes, hardly believing it himself.

"I-Impossible… How could I have left my universe?" Spider-Man asked, expecting a logical explanation. "Aunt May! How is she going to deal with the thought of me being missing?" He said quietly.

"I'm not sure… That part… Not even I could determine." J'onn replied. "Would you be open to more mind reading? I would need to learn who you are and your personal life." He added.

"Sounds fun and all, but I have to go and try to find a way home, so uhh. Maybe next time okay?" Spider-Man said while moving closer and closer toward the door.

Spider-Man opened the door, left and closed the door shut.

Spider-Man started walking toward the teleportation console control panel.

'Oh man…. This is bad… Wait… C'mon Peter, you gotta be dreaming this… There's no way I'm in another universe… What is this, some kind of crossover fan fiction novel?!' Spider-Man thought to himself.

Suddenly, a man with a black cape, a bat-like cowl, a pair of gloves with blades on the sides, black boots, a yellow utility belt, and dark briefs over a dark grey tight-fitting body suit, a cowl with ear like tips rising from the top covered the top half of his face leaving his jaw line exposed and an image of a black bat insignia emblazoned on his chest appeared in the Teleportation Room of the U.N. Orbital Space Station. It was Batman: One of the most iconic heroes on Earth.

Batman walked up to Spider-Man.

"Where is Superman?" The Dark Knight asked with a seriousness in his voice.

"S-Superman? I-In that room right there…" Spider-Man said nervously.

Batman walked up to the conference room door, scanned his hand print, and walked into the Conference Room.

'That was… Scary.' Spider-Man thought to himself. 'All right… Now how does this thing work?' He added.

Spider-Man examined the control panel and typed in some random coordinates he found in a notebook near the panel.

Spider-Man pressed a button on the panel and stepped onto the launch pad. Then he teleported to a city on Earth.

Spider-Man appeared in a city that resembled New York in so many ways.

What he thought to be New York City, was in reality, Gotham City.

Gotham City was basically a criminal underworld. Even in daytime, criminals and corrupt law enforcers alike cause trouble to the people of the city. The weather in Gotham City nearly always foggy, with a mediocre temperature. And the dirty Gotham streets seemed like a trademark to the community.

'Uh-oh… Where am I now?' Spider-Man thought to himself. 'This definitely isn't the place I just was at before.' He added.

Suddenly, a loud alarm in the distance caught Spider-Man's attention.


Spider-Man lifted up his right hand and shot a web line from his mechanical web-shooters. It stuck to a nearly building, and with a running jump he leapt into the air and swung toward the origin of the alarm, shooting another web line to another building to continue swinging above the streets. He repeated the process to quickly move towards his destination.

'Dirty streets, loud alarms going off, crime happening on a daily basis… I'm home…' He thought to himself as he swung from building to building.

Blackgate Penitentiary was infamous for its escape attempts, and as the leading prison in Gotham, holding several, if not all of Gotham's most notorious criminals. Especially Batman rouges.

On this day, the super villain known as Clayface tried his luck at escaping.

"Clayface! Get back in your cell, now!" One of the prison guards exclaimed.

"Get out of my way!" Clayface exclaimed.

Clayface transformed his right hand into the shape of a large fist and punched several prison guards out of his way. Clayface then punched through each of the prison walls, creating a gaping hole in each of them one by one until he reached the entrance, injuring or killing anyone who got in the way.

"Call the police now!" The words of the Warden of the prison echoed over the prison's PA system.

"Is the Warden dense or something? Doesn't he realize that the police are already on their way, if not already here by now?" One of the guards pointed out.

Outside of the prison, Spider-Man observed from on top of a nearby building.

'Is that… Sandman!?' The web-slinger thought to himself, sort of relived because he thought he was back in his own universe.

Spider-Man jumped off of the building then lifted his right arm and shot a long web line from his wrist-mounted web-shooters. It stuck to a nearby building and he used it to swing closer to Clayface.

Several Police vehicles parked several hundred yards away from Blackgate Penitentiary entrance so they would not be too close to Clayface.

The members of the G.C.P.D. got out of their vehicles and started heading toward Blackgate Penitentiary on foot.

Clayface started to run.

Spider-Man let go of his web line and dropped to the ground, landing, twenty yards away from Clayface.

"All right, Sandman, I'm-" Spider-Man said, but then realized the villain was not who he thought he was. "You're not Sandman! But boy! You are an ugly one!" Spider-Man said.

Clayface turned to the young hero and transformed his right hand into a hammer and attempted to crush Spider-Man with it, but Spider-Man jumped backward and out of the way, and Clayface's hammer ended smashing into the ground.

"You're not Batman…" Clayface said, confused to see a hero he had never seen before.

"And you're not a supermodel, but hey, spiders can't be choosers." He replied.

Spider-Man lifted his left and right arms and shot a web line out of each of his wrist-mounted web-shooters, and they stuck to Clayface's shoulders.

"I'd brace yourself if I were you." Spider-Man said.

"What are you-"

Spider-Man turned around, still holding onto both of his web lines, and he he utilized his superhuman strength to lift Clayface completely off of the ground and throw him several meters away, where he crashed into ground with his face in the asphalt.

Clayface stood back up a few moments later and faced the web-slinger.

Members of the G.C.P.D. cautiously approached Clayface and raised their firearms toward him.

Spider-Man noticed the Police Officers, then looked back at Clayface. 'Uh-oh… This can't turn out good.' He thought to himself.

"Put your… Uh, hands in the air!" One of the Police Officers said in his megaphone.

"Wait! Stop!" Spider-Man exclaimed.

Clayface chuckled.

"Open fire!"

"No! You'll only make it worse!" The young hero said.

Spider-Man's Spider-Sense started tingling at the base of his skull.

"Argh!" He growled.

Spider-Man jumped out of the way moments before the Police Officers started to open fire on Clayface, which caused him minimal pain, as his "skin" absorbed most of the impact from the bullets.

Clayface chuckled. "My turn…" He transformed his right hand into a hammer.

Spider-Man jumped into the air and then shot a web line from his web-shooter on his right wrist, and it stuck to a nearby building.

Clayface began to swing at the Police Officer that had yelled out the order.

"Ah!" The Police Officer exclaimed, fearful for his life as Clayface's "hammer" was nearing him.

With only seconds to spare, Spider-Man swung to the Police Officer and grabbed him, continuing to swing up to the top of a nearby building as Clayface's "hammer" smashed into the ground.

Spider-Man landed on the roof of the nearby building with the Officer in hand, and put him down.

"Wow! You saved me!" The Police Officer said gratefully.

"Stay up here until it's safe!" After saying that, Spider-Man shot a long web line then it stuck to a nearby building. Spider-Man leapt off the rooftop and swung himself at a great speed toward Clayface. 'An actual Police Officer admiring me? I could get used to this!' He thought to himself.

"Fall back!" The second-in-command Law Enforcer ordered his fellow officers.

Spider-Man used his built-up momentum and swing kicked Clayface's body, breaking off a large chunk of clay from his body.

Clayface immediately reformed his body.

'Oh, fudge!' Spider-Man thought to himself

Meanwhile at the U.N. Orbital Space Station, Superman, Batman, and the Martian Manhunter were sitting in their chairs with their respective insignias on the back.

"Approximately forty-eight minutes ago, several OMACs that I created to monitor, immobilize, and contain any beings from any other universe were destroyed. The breach was discovered in Metropolis and I know you encountered it Superman. I want to know exactly what happened." Batman told him with a serious tone.

"Your "OMACs" were attacking an innocent being… I had to intervene." Superman replied.

"What being?" Batman asked, confused.

"I'll handle this, Superman." Martian Manhunter said out of nowhere. "Superman brought me this 'innocent being,' as he referred to it. He wanted me to read his mind, and I did."


"We uncovered that he is not from this universe. He's actually from another reality altogether. Neither he nor I were able to find out where he came from, or how he got here." The Martian said.

"Was that who was just in here before me?" Batman asked with his naturally serious tone.

"Yes." Superman and Martian Manhunter replied in unison.

Suddenly, Batman stood up from his chair and ran out of the room, heading to the teleportation device control panel.

'The last person to use this device transported to Gotham City…' Batman thought to himself, as he examined the teleporter.

Batman pressed a button on the panel and stepped onto the launch pad, teleporting into the heart of Gotham City.

Spider-Man dove off the building he was on. As he fell toward the ground, he lifted his right hand and shot a web line toward a nearby building, where it stuck and allowed him to swung toward Clayface as the villain transformed his hand into a hammer, and extended his arm toward him, but the hero let go of his web line and narrowly got out of the way of the hammer.

Spider-Man landed on the ground. "Almost had me there!" The young hero said mockingly to Clayface. 'I gotta get away from these cops so they don't get caught in the crossfire.' He thought to himself.

Clayface groaned. He transformed his right hand into a hammer and attempted to punch Spider-Man, but the hero dodged the attack.

Spider-Man jumped in the air and with his right hand, he shot a web line out of his right arm's web-shooter, catching on a nearby building. "Let's play follow the leader!" He exclaimed at he swung away from the prison.

Clayface transformed his hand in a saw. "Let's not!" Clayface extended his arm to Spider-Man's web line and cut it in half, and Spider-Man landed on the ground, face first.

Spider-Man sat up. "Well, that clearly didn't work… However… Old mud mouth doesn't seem to care about them." He said, as he glanced over at the Officers.

Clayface walked toward Spider-Man. "Ha ha ha ha!" He chuckled. "Nice try, but I've had that trick played on me before." Clayface transformed both of his hands into hammers. "What do you think? That I'm stupid?"

"Well you do look stupid." He replied mockingly.

Clayface repeatedly attempted to hit Spider-Man, but he dodged all of the villain's attacks continuously. "By the way, the hammer this is gettin' old real fast," Spider-Man said. "Why don't you try something useful? Like a drill, or a sword?" He added.

Clayface transformed his left hand into a drill and then he transformed his right hand into a sword.

Spider-Man's eyes widened. 'Damn!... Me and my big mouth!' He thought to himself.

Clayface smiled. "I'm going to enjoy this." Clayface said, thinking he had the upper hand.

As Clayface raised his drill, Spider-Man stood up and prepared to dodge, then a small blue coloured grenade bearing the insignia of a bat lodged into Clayface's body.

"Batma-" Clayface began, as he looked down and examined the grenade and recognized Batman's classic insignia.

The grenade exploded, revealing itself to be a strong ice bomb. Clayface was frozen completely solid in every sense of the word.

"Huh?" Spider-Man walked up to Clayface's now frozen body and knocked on it to see if it was only some kind of trick. "He's been frozen solid… But how?" Spider-Man looked around, and he had seen the same hero he had saw before as he had left the Space Station: Batman.

Spider-Man assumed his fighting stance as Batman walked toward him.

'My Spider-Sense isn't going off… He must not be a bad guy.' Spider-Man thought to himself.

Batman and Spider-Man had a silent stare down, with neither of them showing any weakness whatsoever.

"What?" Spider-Man asked, breaking the silence.

Batman continued staring down Spider-Man. "I have a few questions for you, and you're going to answer them… Understand?" He ordered.

Batman and Spider-Man finally speak to each other with Batman being intimidating as usual. What does this mean for Spider-Man? Find out in the next chapter.
