A/N Just a quick note. For the sake of this story the characters of Superwoman Justice League are doppelgangers for their Arrowverse version. Unlike in the main storyline where they are comic/cartoon appearance based… e.g Barry in SW is blond haired, blue eyed. While Barry in Arrowverse is brown hair, green eyed. Oliver Queen in SW is older, than Arrow version. To larger changes, with Wally in Arrowverse is African American, to SW Kid Flash is (will be) based on Young Justice Wally, with red hair and green eyes.

So just in this story, the doubles look like the Arrowverse version.

Earth - 1

Central City.

Cisco Ramon was hard at work. His concentration intense, as he focused with unwavering determination on his task. With a slow and deliberate delicate touch, he reached out to put the final touch on his work.

The next pen balanced between his nose and his lip.

Movement caught the corner of his eye and he glanced over to spot Caitlin leaning against the computer terminal with an arched eyebrow. His pursed lips relaxed scattering pens around him.

"Yes?" He asked keeping his voice even.

"Bored?" She asked, her voice just as even.

As always, he broke first, sitting up in his chair. "Yes!" He cried pushing his hands into his long hair, before looking up at Caitlin. "Not asking for like a mega attack or something just you know something!"

Just then an alarm started to sound around the lab.

"Something like that?" Caitlin questioned looking around.

"Ok that's kinda freaky." Cisco replied even as he went to work on his computer.

"What's happening?" She asked as she moved around the computers to stand next to him.

"Give me a sec…" He muttered before breathing. "Oh no way…."

"What?" Caitlin asked concerned. "What is it?"

"Breaches." Cisco informed gesturing to the main computer screen as an image of Central city came up with red flashing circles. "Multiple Breaches! Two are in Central City."

"Multiple Breaches!" Caitlin cried, she took a moment before asking. "Like what happened with Zoom?"

She was referring to what had happened over a year and a half ago. When multiple breaches had opened between their Earth and a parallel one. The multiple entry points into their world had helped Zoom to bring his meta army over. Plus, their own adventures in Earth-2 had left deep scars in Caitlin.

"We don't know that," Cisco said in a comforting tone. "We don't even know what world they connect to. If they even connect to anywhere. I'm getting weird readings off them. It's like nothing I've ever seen before."

"Is that why you're not…" She wiggled her fingers at him.

"Vibing?" He filled in, "I dunno. It's not an exact science."

Something seemed to spook him as he sat back from the computer. "Ehhh Caitlin. One of the breaches. It's in the building." He whispered the last part pointing to the ground.

Caitlin looked around as if half expecting a swirling gaping hole to the multiverse would appear right in front of them, when nothing became apparent she turned to give Cisco a nervous look. She stated more than asked. "We need to find it don't we."

###

It wasn't your cliché horror movie scene with a rundown hallway half lit with flickering lights. The S.T.A.R labs corridor was the same pristine white they had always been. The lighting while dim wasn't flickering or too faint to see by.

But still Cisco Ramon and Caitlin Snow moved down the corridor as if expecting a jump scare at every doorway they past.

"I still think we should call Barry," Caitlin hissed into Cisco's ear, huffing a little when he waved her off. Probably more creeped out by the sensation then the comment.

"It's fine. It's fine." Cisco repeated, the second one more to himself. "We don't even know if anyone came through. It might just be a breach."

"A breach with unknown factors," Caitlin muttered, she was pretty sure Cisco had heard her, but he gave no response. She froze suddenly grabbing hold of the back of Cisco's shirt and whispered. "What is that?"

The whirling sound of machinery and the repeated heavy thud of footsteps echoed down the forked corridor ahead of them. It felt like and age before a figure appeared from around the corner. A silver metallic body gleamed in the low lighting, a red glow seemed to emanate from its body.

Cisco made a weird squawking sound, before crying out "Terminator!"

The metal head turned towards them, revealing a dark skinned human face. A single dark eyebrow frowned at them.

"Seriously?" The metal man asked.

Cisco swayed slightly, eyes flickering as he wheezed. He breathed out finally. "Robocop."

The solo human dark eye seemed to roll at them. Before he turned on his large metal foot to face Cisco and Caitlin. "Where am I?"

"S.T.A.R Labs," Caitlin called softly over Cisco's shoulder, shrinking back as that dark eye and the glowing red one moved to look at her.

"I know that," The stranger replied, "I meant what Earth?"

"What Earth…ohhh." Cisco realised, pointing to the ground and telling the visitor. "Earth 1. This is Earth 1."

"One," The metal man repeated, "You named it yourself?"

Cisco cleared his throat remembering the multiple conversations that he had, had with Earth 2 Harrison Wells about team Flash calling their own Earth, Earth 1.

"It's complicated." Cisco replied finally. "Who are you? What Earth are you from?"

"I am Cyborg." The metal stranger replied.

"That you are." Cisco replied in no small amount of awe.

Cyborg ignored him, as he seemed to gaze off into the distance.

"Ehhhh…. you okay there man?" Cisco asked after sharing a look with Caitlin.

"My com unit is down," He informed them, "I'm accessing wireless networks, attempting to see if any of my team came through as well."

"The other breaches," Caitlin stated.

"How many opened?" Cyborg questioned,

"Two in Central City," Cisco answered, "More opened in other cities."

"So more of your team might have come through?" Caitlin asked, unsure of how she felt about the fact. "So, you might not be alone?"

"I'm not alone," Cyborg corrected, turning to face down the other corridor.

Lighter footsteps echoed as a new figure appeared. She was tall, long black hair hanging down her back and over a bright red bustier. The golden trim gleamed in the low light.

"This place is abandoned," the woman said to Cyborg. She turned to face Caitlin and Cisco revealing a beautiful face and a golden diadem. "Not completely though, it seems."

"Greetings," The darkhaired beauty said smiling, "I am Diana. But people call me Wonder Woman."

"I'm …. I'm … I'm." Cisco tried unable to complete the sentence as his brain seemed to quit on him.

"Caitlin," Caitlin introduced herself quietly, "This is Cisco."

"CISCO!" Cisco shouted, jumping on the name. Not even noticing as Caitlin flinched at the loud sound. "Me Cisco, I'm Cisco. Hello Cisco."

Wonder Woman and Cyborg exchanged a look, and Caitlin finally stepped out from behind Cisco. No doubt realising that she might need to take the lead while Cisco's brain rebooted.

"Maybe we should move this conversation some place else," Caitlin said, before looking at Cisco, "And it might be time for us to call in our…. friend."

Metropolis

Bruce was half buried in the guts of the Batwing. Attempting a field repair on whatever the trip through that mutated boomtube slash portal had caused it.

He'd pushed his cowl back too after Superwoman had helped move the Batwing to a more secluded part of the woodland around Metropolis.

But not the Metropolis they knew.

A soft thud of two bright red boots landing nearby had him looking up. Superwoman looked…well disturbed. Her face was pale, and her lips pursed, as they usually did when she was clenching her teeth. Which she only did when she was stressed about something. Her blue eyes kept flicking the direction of the city, the glow of not-Metropolis visible in the distance.

"It's not just Metropolis that is different," She informed him, inhaling sharply "Other Cities are different too…some are not even there." She looked around, no doubt scanning the distance far beyond what any person could see, aided or unaided. "The world is different…where are we?"

"Facts," Bruce stated wiping the grease off his hands as he walked along the wing of is plane. "We were pulled through a portal. The world around is different from the one we know. Therefore, it's not our world. Is it some kind of recreation of another world? But given the size and population…would be difficult. Or is it, a parallel world?"

"Parallel world." Superwoman echoed.

"A theory that might just be in the process of proven fact." Bruce stated, moving to jump down from the Batwing. "We need a more in-depth study, and to see if there were any other portals, and if any other members of the League were pulled in."

"Coms aren't working so….," Superwoman replied stepping back and getting ready to take off. "I'll do a closer sweep."

"No," Bruce replied moving forward as if his closeness could prevent her from taking off should she chose to. "We don't know anything about this world. It could be hostile, there could be someone here that could match you. There could be another you."

"Another me," She repeated, licking her lips and looking up into the sky. Unable to think about what it might be like to find another person just like her. It just seemed too foreign. "Okay. So, what then?"

"We do this my way," Bruce simply replied.

Star City

Spartan paused on the street looking up to the rooftops over him. The night was calm and mostly silent. Completely different from the reports they had received, that not that long ago it was as if the sky itself had been torn open.

He turned to watch Green Arrow step up behind him scanning the buildings as he had just been doing.

"Are you sure this is the place," The archer growled out.

"Reports say people were seeing strange lights in the sky right above exactly where you are standing," Felicity's voice said over their coms.

"Well what ever it is, it's gone now," Spartan informed her.

"We need to get on the roof," Green Arrow ordered.

###

They split up as they searched the rooftop.

Diggle making his way slowly across the roof, not a hundred percent sure as to what he was looking for. But had summed it up to anything basically covered with 'weird shit', as the police report had stated.

He hugged the brick wall, his gun out and ready.

He stepped around the corner and paused. Green Arrow was standing across the roof from him, his hooded head facing out to look at the city. Dig glanced over his shoulder in the direction he swore he saw Oliver go, then back at the archer in front of him.

"Hey man, where did you come from?" He called. But even as the words came out, Dig started noticing things that were different. The mans suit was different, the green colour brighter. His quiver was larger, covering more of his back then Oliver's. As his hooded head turned, Dig spotted a blond pointed goatee. Scruffy as Oliver's face got, Dig was pretty sure his friend didn't suddenly sprout a beard while he wasn't looking.

He dropped into a firing stance before he finished thinking, that this was not Oliver.

"Don't move!" He shouted pointing his gun at the stranger. The unknown archer spun knocking an arrow, with a speed he'd only ever seen with Oliver. It didn't sit while with him, making him think that this man was more than just a simple copycat.

"You picked the wrong man to copy. Believe me." Spartan called, trying to ignore every instinct that said this man was in fact Oliver.

"Copy?" The mimic repeated. his voice was surprisingly light, not the gravelly tone Oliver favoured.

"Who are you!" Oliver's familiar growl demanded, as he appeared on the raised part of the roof above them.

"What the…" The copy said at the sight of Green Arrow. He actually sounded confused, which didn't make any sense.

"I'm not going to ask again!" Green Arrow demanded, his growl deepening into a more menacing snarl.

"Seriously?!" The look-alike managed. "You got it all wrong. If you're going to copy me at least get it right. Who do you think I am Batman?"

"Batman," Dig muttered in confusion.

"Copy you!" Green Arrow shouted sounding confused and mad about it. "You're the one copying me!"

"Okay this is getting weird." The copy said sounding just as confused as they were. He lowered is bow slightly and took half a step forward. It was apparently half a step too far. Oliver had bow up and aimed at his copy, while Dig aimed again with his handgun. The other archer followed, his bow also aimed back at them.

Suddenly a black figure was beside Diggle, knocking his gun from his grasp and sending him to the ground with a sweeping kick. The copy fired his arrow, but his aim was way off. At least that's what Diggle thought when the arrow exploded in a white flash mid-air.

Oliver who had been rolling out of way, still growled slightly as the bright light blinded him. He came up onto his knee, pushing himself to his feet ready to fire at the pretender. When he froze.

Standing between Oliver and Dig was a woman. With a black suit and blond hair. She was also a ghost.

"Laurel?" Oliver breathed in shock. Dig wasn't much better, as he lay on the ground mouth open.

But Laurel seemed to give them a strange look, before glancing back at the look-alike.

"You okay," She asked, and Oliver gave a shuddered breath at the familiar sound of her voice.

"Fine," The mystery archer replied. "It's just been a weird night."

"Laurel," Oliver repeated dropping down to her level, so he could talk to her face to face. He noticed the way she dropped into a fighting stance and stopped his advance. "How are you here? Laurel you died…."

"Died?" She repeated, frowning as she looked between the two archers. "Why do you keep calling me Laurel?"

It was then Dig and Oliver noticed the difference between this woman, and the one they had lost. The suit was different, the hair was different. She wasn't even wearing a mask. But it was Laurel. Oliver knew it, he looked at her, and he knew it was Laurel.

He stepped forward, reaching up to pull his hood off. Yanking his mask down to his neck. Laurel's jaw dropped, with wide eyes she glanced between Oliver and the other archer.

"What…." She breathed, even as the look-alike stepped forward pulling his own hood back. Revealing Oliver's face with a blond beard.

"Well. This makes a weird night weirder." Bearded Oliver said with a shocked laugh.

"What the hell is going on?!" Diggle demanded.

###

Flash circled the city once, then another three times just to be sure.

This was not his city.

It looked like it, slightly. There were faint echoes of it. But it wasn't the city he protected, the city he lived in.

He had no idea what was going on. His com unit was dead, he had no way of contacting his teammates. He had been about the check out some of the other cities when a near by car slammed into another car.

It was in fact blocks away, but to him everything was nearby.

The crash was seemingly frozen when he arrived, one car still hanging mid-air. As he sped around pulling people out of danger. When another figure appeared in the speed force with him. Dressed similar to him, in head to toe red. The two speedsters looked at each other before running off to the outskirts of town.

They came to a stop and faced each other, circling on the empty road.

"Who are you," The newly arrived speedster questioned.

"I'm the Flash." He replied, gesturing to himself as if to say, 'who else'.

"No," The other answered slowly. "I'm the Flash."

"Pretty sure I'm the Flash," Barry replied, smiling as he introduced himself. "Fastest man alive!"

The new speedster made a soft sound of realisation and reached up to rub the edge of his mask around his eye. "Ok, this is going to sound weird." He said finally, "Did you happen to run through a portal of some kind?"

"Oh yeah," Barry replied in realisation, clicking his fingers.

"I hate to tell you this," The other Flash said as gently as he could. "But I don't think you're on your Earth anymore."

"Say what?" Barry questioned.

"You fell through a breach I think," The other Flash explained. "Could be time travel. But you kind of look like me. So possible Doppelganger. And I once accidently travelled to another world, while trying to get faster."

"Doppelganger," Barry repeated, before stating in realisation. "Parallel Earth," He turned looking around with full awareness now. "Oh wow."

"Look. My team," The other Flash stated gesturing back to the city. "We have some experience with this kind of thing."

"Why am I even staying with you," Killer Frost hissed, as Harley worked over Metallo's body. "And how the hell do you know what to do with him. You grabbed his case in the chaos."

"When ya hang wit Mr. Jay for long enough, you learn to be quick on your feet." Harley laughed, her tongue poking out the corner of her lips as she concentrated. "Puddin' is buddies with Luthor, sooooo… we found out all about Metal boy here."

"Does Luthor know you and Joker found out about his projects?" Killer Frost asked in curiosity. She got a non-committal hum and shrug in reply.

"Worked out well for us," Quinn sung, as she finally clicked the chunk of Kryptonite into place. She lent over staring into metal eyes as they slowly lit up. "Wakey Wakey sleepy head!"

"We have so many fun things to do."

A/N Omg Has it really been so long since I started this story? I just posted and left it….

While to be fair, I wasn't completely sure about this story. Truthfully, I needed to know people would actually read it before I continued. So, thank you to everyone that did review, fav or follow. I'm still iffy about it. But if it continues to get attention, I'll continued to give it attention too.

Please Review.
