Chapter 6- Doppelgangers

"You're kidding me", Curtis said to Felicity on the video chat. "Are you kidding me? This feels like a really bad wedding prank."

"No, I wish", Felicity said.

"You want us to come, then?" Curtis asked. "Diggle, Rene, and I can be up there in a- what's another word for "Flash"?"

"No", Felicity immediately vetoed the idea. "We need you guys in the bunker, expanding our search for the Earth-Xers. I linked S.T.A.R. Labs' system up with ours so you can know what's going on as we do."

"Copy that", Curtis said with a smile. "I will get to work on hacking Palmer Tech's spectrometers-heh- to help the search for these aliens."

"Yes. Weird, cyborg aliens", Felicity said before waving her hand. "See you soon."

The video chat was then cut.

Ollie was standing quietly in a corner.

"Hey", Chloe called out as she approached him.

"Hey", Ollie said. "Thought you'd be helping the others in finding the Earth-Xers."

"They have it handled actually. They are using dimensional vibrations to track the Earth-Xers down, which isn't too difficult", Chloe informed as Ollie nodded.

"Sounds complicated", he quipped.

"Not too much", Chloe said. "I came to see how you were doing."

"I'm terrified", Ollie said honestly as he looked into Chloe's eyes with genuine fear in his eyes. "If my circumstances had been a bit more like his, I wonder if I would also have become a monster and a traitor to humanity."

"Hey, don't say that", Chloe said as she hugged him. "I know you. You can be egotistical, a jerk, but never a bad person, much less a monster. You are a hero, Ollie, and a good man, I know that."

"Thank you", he said with a genuine smile, feeling comforted by his wife as the two kissed.

Later, Ollie and Chloe walked into the main lab.

"What's going on?" Ollie asked.

"Our alien friends broke into Dayton Optical Systems", Felicity said and showed them a video of Terminator and Dark Archer leading some of those cyborg alien soldiers into the building, cutting down the security guards.

"All right", Barry said. "Let's head out."

"Only you, me, Clark and Kara", Oliver announced to everyone's shock.

Sara tried to protest, "But Ollie-"

"This could be a trap", Donald said as all looked at him. "So all of us going there is not the best idea."

Nyssa, Laurel and Sara nodded as they understood his reasoning.

"So me and Thor can stay here in case they try to make a move for this place", Simon said.

"Thank you", Oliver said as Donald and Simon nodded.

"Okay then", Clark said.

"Let's go", Kara said.

"Good luck", Donald said to them as he shared a kiss with Kara, Lois with Clark and Nyssa with Oliver before they prepared to head out.

Later, Clark and Kara landed on the ground and Barry sped up next to her. Barry looked at them both as they straightened and then shrugged.

The three then waited for a while as Clark and Kara whistled. That moment, Oliver arrived, riding on his motorcycle. He pulled over near them and got off.

"Just a reminder", he said in an annoyed tone. "Super speed- I don't have it."

"Noted", Clark, Barry and Kara said simultaneously and they moved towards the building.

"So what do we know about this place?" Barry asked. "Why are the Earth-Xers targeting it?"

A distorted voice then spoke up, "Because-"

The trio stopped as they saw Brightburn, Dark Arrow, Overgirl and Zoom walking towards them, the speedster carrying a device in a glass cube.

As he put it down, Dark Arrow finished his sentence. "They had something we need."

Green Arrow began, "Whatever you stole-"

"Well, we're gonna want it back", Flash finished.

"Right now", Superman added.

"Your confidence is predictable", Dark Arrow said scornfully. "You've faced some of the greatest evils known to man and you've defeated them. But if you think so highly of yourself that you can defeat every threat that comes your way-"

He then pressed a button and to the trio's shock, the masks of Brightburn, Dark Arrow and Overgirl faded away along with the device on the Zoom's face who had now taken off his mask.

"How do you feel about us?" Brightburn asked smugly.

"Not again", Barry groaned as he saw the speedster looking at him with his own face, a smug smile on his face.

The four were taken aback by the fact that these people were their doppelgangers.

"This is sick", Oliver muttered as he stared at his doppelganger.

"To look at your reflection and see only weakness?" Dark Arrow asked rhetorically. "I agree."

"Never thought I would see an evil me again", Barry groaned.

"Oh yes, I know about that one", Zoom smirked. "He was nothing more than a stupid, pathetic, lovesick puppy who couldn't look at the big picture. You will find I am much more than he could ever hope to be."

"I do think you're even more delusional than him", Barry snarled.

"At least I don't look like a half-baked pizza", Zoom smirked before gesturing to his face. "Plus- young and handsome. And actually smart, unlike you."

"We have Prometheus", Clark informed them.

"Yes, my brother is with you, I know", Dark Arrow said as all looked a bit shocked at that.

"He is your older brother?" Oliver asked and he nodded. "Should have seen that coming."

"You are all soft idiots shocked by anything", Brightburn told them scornfully.

"We've been watching you", Overgirl said. "We've been watching all of you and how you've squandered the potential of your worlds. On our Earth, we've developed a meritocracy. Those who side with us survive, those who don't are put to death. We've accomplished greatness."

"You're perverse", Kara said in horror and disgust.

"No, Kara, you're the perversion", Overgirl told her scornfully with disgust. "One of the most powerful beings on the planet rendered weak by saccharine Americana?"

She then chuckled and said. "My pod was blessed to crash on Earth, as our Lord graced it with his arrival."

"Then go back there", Barry said.

"This is not your earth", Oliver snarled. "Leave."

"I don't answer to the likes of you", Dark Arrow sneered with contempt in his voice. "My allegiance is to our Lord and to my wife."

As he said that, he exchanged a look with Overgirl.

"His wife?" Kara said in disgust as she realized the relationship between her and Oliver's doppelgangers. "Gross!"

Turning to Oliver, she said. "No offense."

"None taken", he assured her.

"Well, you do have better taste in men than my cousin", Brightburn said to Kara with a smirk as she glared while Overgirl smacked his arm.

Turning to the Earth-X trio, Clark then said, "Last chance."

"Go home", Oliver commanded.

"And stay there", Kara added.

"All of you", Barry finished.

Zoom cracked his neck and putting his mask back on, sped towards Barry. Barry rushed him and the two started running around, fighting.

Brightburn flew at Clark who flew back and they flew into the air, clashing as a shockwave was produced.

Oliver aimed an arrow at Overgirl.

"And what do you think that's going to do?" Overgirl asked him mockingly. "Bullets bounce off of me."

"Oh, this arrow won't", Oliver retorted confidently and fired.

As the arrow flew towards Overgirl, its lead casing fell away, revealing a green arrowhead. It hit Overgirl on the shoulder and embedded into it. She winced in pain and staggered back, her eyes full of pain and surprise.

"Is that a Kryptonite arrow? Really?" Kara asked.

"It was in case an evil you ever showed up!" Oliver justified.

"I don't care about the why, I'm thinking more about the how", Kara said.

Overgirl pulled out the arrow and leapt into the air to throw it at Oliver. Kara stepped in the way and used her super breath. The powerful wind sent Overgirl back by a few feet. She crashed through some glass as Dark Arrow ran to support her.

Clark and Barry were then thrown to the ground by Brightburn and Zoom respectively.

"Get the prism out of here!" Dark Arrow told him. Brightburn and Zoom quickly complied and sped away.

Dark Arrow supported Overgirl and asked in concern. "Are you all right?"

"I'm pissed!" she growled as he helped her to her feet.

"Well, take it out on that", Dark Arrow said as the two looked at an unfinished construction site.

Overgirl smirked and fired her Heat Vision. It damaged the structure enough to make it collapse.

Oliver and Kara heard the terrified screams of the construction workers. Kara flew up to the construction site.

Oliver helped Clark and Barry up and the three looked at the construction site.

"It's gonna fall", a horrified Barry said.

"All right, get me over there", Oliver commanded and Barry complied as he grabbed Oliver and sped over to the construction site while Clark and Kara flew towards it.

Kara grabbed a falling beam and held it in position while commanding. "Get the workers to safety!"

Clark then fired his Heat Vision to re-weld the beams into the structure while Barry sped around and saved the workers.

He then sped up and stood on a beam.

"We need to stabilize the building", he said.

Oliver had been put on the topmost beam by him. He fired an arrow with a line and swung to the beam. Like that, he used his arrows with lines at the weak points of the structure while Clark again used his Heat Vision to re-weld the beams into place. In no time at all, the building was stable again.

"The site's cleared", Barry said.

"And stabilized", Kara said.

"Nice work", Clark said to everyone.

"Let's not celebrate just yet", Oliver said. "We gave those doppelgangers the window they needed to escape."

"Escape with what?" Kara asked.

"Dayton Optical Systems calls it the Prism", Chloe explained later in S.T.A.R. Labs.

"What on Earth do they need a sub-light generator for?" Harry asked no one in particular, "It's basically a spectral emitter that-"

"Uses quantum entanglement", Harry, Chloe and Felicity finished together.

"You could also use it to create a stable fusion reaction", Caitlin said as she walked towards the computer.

"Ok, which all means what?" Laurel asked.

"Not all of us are rocket scientists", Thea pointed out.

"So we need explanation in simpler words", Nyssa said.

"Well, basically", Harry said. "The device they stole can be converted to a neutron bomb."

"Pfooo", Felicity did a failed imitation of a bomb exploding.

"Sounds terrible", Donald said as he exchanged a look with Simon.

"Oh boy!" Laurel said.

"I wish I hadn't asked ", Thea said.

"Well, not asking won't change its intended effects", Lisa shrugged.

"The bottom line is that we have to catch these parallel-earth goose-steppers", Chloe then said as Harry and Felicity nodded.

"This might help", Barry said as he walked in, holding the kryptonite arrow.

"Is that a kryptonite arrow?" a startled Alex asked as she took it from Barry.

"Yup", Barry said simply

"I know I shouldn't have to ask this question, but I have to ask this question", Felicity said, "Oliver didn't shoot Clark or Kara, did he?"

"Sort of", Barry said before revealing, "The other archer and flying man and woman are Oliver, Clark and Kara of Earth-X."

Everyone gave him shocked looks on hearing that.

"When you said that Earth-X was horrible, you might have undersold it", Caitlin told Harry who simply nodded.

"So an evil Smallville?" Lois asked and Barry nodded. "Damn! For some reason, I really don't want to see that."

"Wait a minute", a confused Alex asked. "How-how could there be another Kara?"

"Well", Donald started explaining. "There are infinite Karas, just like there's infinite Kryptons and infinite Earths. You already met two Olivers, right?"

"Yes, though I look different from the one that lives here", Ollie said.

"And they also have a speedster who looks like Zoom, only he is my evil doppelganger", Barry announced. Caitlin's jaw gaped open in horror and shock on hearing that.

"I don't even want to see that", Caitlin said with wide eyes.

"Me neither", Lisa said.

"So another evil you then", Donald said.

"This one isn't pathetic like that one though", Barry said.

Felicity then said, "Ok, if that arrow has not-so-Supergirl's blood on it, we c-"

"We could track it using quantum analysis", Harry said.

"Hey, guys, I think I might have a quicker way", Caitlin announced as she looked at the arrow through a microscope.

Donald, Simon, Barry, Alex, Harry, Chloe, Lois, Ollie, Nyssa, Laurel, Thea, Lisa and Felicity walked towards where she was.

"These red blood cells are suffused with shortwave radiation", Caitlin said as she looked up.

"Solar radiation?" Chloe asked.

"Yeah, incredibly high amounts", Caitlin said, prompting Alex to take a look as well. "Like nothing I've ever seen."

"Higher than the normal amount in Kryptonians?" Donald asked.

"Looks like it", Alex said.

"That cannot be good", Simon said.

"Can you track it?" Barry asked Chloe and Felicity.

"Well, I once caught a deranged serial killer off his face cream, so", Felicity said as everyone nodded. "No joke. Heh!"

"Let's just do it", Barry said. "And fast."

"Ok", Harry said as he went off to work with Chloe, Caitlin and Felicity.

Later, after completing the search, Chloe told everyone. "Your evil doppelgangers are at a shipping depot outside Danville."

"Let's move out", Oliver said.

"Fast", Barry said.

"To battle", Donald said.

"To battle", Simon said too.

Sara suited up took her bo-staff.

Alex suited up and took her gun.

Roy and Thea put on their hoods after having worn their masks and the rest of their suits and picked up their bows.

Jax and Stein joined hands and merged into Firestorm.

Laurel put on the suit she had worn when she had come over to Earth-1 and put on her mask too.

Lisa put on her suit and loaded the Cold Gun which belonged to her brother.

Nyssa put on her bow and quiver before twirling her sword and sheathing it.

Clark did a spin motion at super speed and when he was done, he was wearing his suit instead of civilian clothes.

Ollie picked up his bow, testing its range after he had put on his suit.

Donald and Simon slammed their canes to the ground and there was a flash of lightning before they turned into Thor and Bill.

Barry put his cowl over his head.

Kara ripped off her shirt, revealing the Supergirl suit inside.

Oliver put on his suit. He picked up his mask and put it on before putting the hood over him. Picking up his bow, he went out.

And then- Thor, Superman, Beta Ray Bill, the two Green Arrows, Flash, Supergirl, Black Siren, White Canary, Arsenal, Speedy, Firestorm, Golden Glider, Nyssa and Alex headed out to fight.

And we finally end this chapter. Next one is where things are gonna get really good.

Hope the interactions with the evil doppelgangers were enjoyed.

The Kara in my series is much more mature than canon Kara, so she isn't getting her panties in a twist over Oliver having a kryptonite arrow, though she is still wondering how he got it, since Kryptonians aren't a thing on his Earth.

Hope everyone enjoyed and see you all next time with another chapter. Stay safe from the coronavirus ya all!
