Thank you to everyone who has favorited, followed or reviewed this fic so far.

Guest: Thanks for the review. Glad you think Thawne's return makes sense. I don't think I have seen that 'behind the scenes.' Let's just ignore it. Matt and the others will show up really soon in a few chapters. And I promise it'll be worth it. Glad you found the previous chapter great.

Elseworlds Part 1 was pretty fun. Barry shooting Oliver and saying 'You have failed this city!' to Amazo was fun. And I loved seeing Superman and Lois. The last fight was great. I'd say the crossover's off to a great start. Now I'm looking forward to tomorrow's episode and Batwoman.

Warning: Dark chapter

Chapter 7- Welcome to Earth-X

"Supergirl and Firestorm are sweeping the perimeter", Oliver said as Barry sped up to them.

"It's done", he said, "Its wall-to-wall Hydra soldiers in there."

"Laurel, Alex and I will take up breach positions on the northwest corner", Sara said before turning to Laurel, "If that's ok with you."

"It is", she said.

Alex then said, "S.T.A.R. Labs thinks they converted the sub-light generator- the Prism that they stole- into some kind of superweapon."

"Speaking of super, theirs is our biggest threat", Barry said.

"Agreed", Oliver said, "Let's take her out first."

"This is gonna be weird", John commented.

"Get over it, John", Roy said.

As they walked, Supergirl and Firestorm flew over them.

Later, Oliver walked into the building. Some Hydra soldiers noticed him and aiming their weapons said, "Halt!"

Oliver was about to take out an arrow when Barry arrived and knocked them all out with his super speed.

"Couldn't have left one for me?" Oliver jokingly asked.

"I'm saving Hydra you for you", Barry revealed.

"There's no sign of the prism", Alex said as she walked up to them.

"Well, it's gotta be here somewhere", Barry said.

"They must have hidden it somewhere", Laurel said.

"We got incoming", Sara said as she looked in the front and readied her bo-staff.

"Oh boy!" Roy said.

"Well, let's do it", John said as he aimed his gun.

Soldiers surrounded them from all sides.

"Stay where you are!" one of them commanded.

Barry then saw Thawne speeding around and ran after him. Oliver turned and fired at a soldier, getting him. Roy fired at one and he was out too.

Alex and John took out their guns and started firing at the Hydra soldiers.

Oliver shot one down and grabbed another's head between his feet before flipping him down. He got up and kicked another to a wall before shooting him down. He turned to block the attack of another soldier and lipped him down too.

Roy swept a soldier's feet from under him and smacked him on the face, knocking him out. He then fired at another soldier who was trying to aim at him and put him down too. He then flip kicked another away.

Alex shot down two soldiers. She then dodged the knife of a third one and sliced him down with her own knife. She looked up to see Overgirl flying while Thawne sped past her.

"I see their Flash, their Supergirl", she announced.

A soldier attacked her from behind. She was about to attack him when John shot him down.

Sara knocked out a soldier with her batons before turning to block another soldier's strike. She struck him on the legs and he tripped.

Laurel dodged a punch of a soldier before flipping him to the ground and knocking him out with a kick. She then turned and punched another soldier away. Three more aimed their weapons at her but she used her Canary Cry to knock them away.

Oliver smacked another solider away.

"Yeah!" Oliver said as he turned to face Sara, "I see them!"

"Where's their Arrow and the horned man?" Sara asked as she knocked another soldier away with her batons.

She then ran and flipped another soldier down while Alex shot down another one and Laurel threw off two more with her Canary Cry.

At the same time, Darkdevil and Dark Arrow stood in front of S.T.A.R. Labs.

Harry was walking through the hallway, cleaning his glasses. As he looked up while putting them back on, he froze in his tracks on seeing his path blocked by Darkdevil and Dark Arrow.

"Oh God!" he said, horrified.

"There is no God", Dark Arrow announced.

"There is only the Devil", Darkdevil said.

Harry ran from there towards the button while the two slowly walked after him. He managed to press the button and the alarms blared.

He looked up to see the two standing right in front of him. Dark Arrow smacked his face with his bow, knocking him out.

"You'll be useful", Dark Arrow then said.

At the shipping depot, two soldiers were running around when Kara fired her heat vision near their feet, throwing them off.

As Sara engaged two soldiers, Firestorm blasted some away. Sara managed to defeat them both.

She then flipped to avoid another soldier's bullets who was thrown away by Laurel's Canary Cry. As another tried to fire at her, Alex shot him down.

She blocked an attack from another soldier and shot him down.

Oliver smacked two soldiers out before sweeping another's feet from under him and shooting him out. As another soldier leapt at him, he kicked him on the knee and he was down. He then flipped another solider down and pushed another away before turning-

Only to get hit by a circular blur on the head. The hit sent him flying off by a few feet and he crashed into some crates. The blur was plucked out of the air by a hand and revealed to be a shield.

It was Captain Hydra!

At S.T.A.R. Labs- Caitlin, Thea, Mick and Felicity saw the footage of Darkdevil and Dark Arrow walking through.

"You and you", Mick said to Thea and Felicity, "Hide!"

"I can fight!" Thea protested.

"Someone needs to keep Felicity safe", Caitlin pointed out the worst case scenario.

"What about you, Caitlin?" Felicity asked.

"It's gonna get a lot colder in here", Mick said and Caitlin got the hint. Thea lead Felicity away.

At the shipping depot, a dazed Oliver opened his eyes, a ringing in his ears. Still on the ground, he looked around at the fighting that was going.

However, his attention was drawn by Laurel's battle with Overgirl. She let out a Canary Cry which Overgirl managed to dodge and then she pinned Laurel to a pillar, her hand wrapped around Laurel's throat to prevent her from screaming again.

In another corner, Captain Hydra blocked some bullets fired at him by John and swept his feet from under him before kicking him out. Roy tried to flip kick him but he backed to avoid. Roy then tried to smack him with his bow but he grabbed it with his hand and smacked Roy on the face with his shield, knocking him out.

Alex turned to fire but Black Widow grabbed her hand and punched her on the face, making her stagger back as she snatched her gun. Before Alex could recover, Black Widow smacked her on her face with the gun, putting her down. She tried to get up but Black Widow kicked her out.

Seeing Laurel pinned to the pillar, Oliver suddenly found his strength again and managed to get up. He fired a kryptonite arrow but to his horror, Overgirl caught it mere inches from her face.

Throwing Laurel away, she turned around and snapped the arrow into two.

"Burn!" she said before firing her heat vision. Oliver rolled out of the way and the beam hit a steel pillar which deflected the beam back at her, sending her flying off.

Darkdevil and Dark Arrow walked into the Speed Lab, looking around at the red lit room. Suddenly, Mick jumped out and fired at them with his heat gun.

The two flipped around two avoid the flames.

"Afraid of a little heat?" Mick asked mockingly.

Darkdevil threw his club and it disarmed Mick before returning to him.

"No", Dark Arrow said and fired. The arrow embedded itself onto Mick's chest and he gasped in shock and pain as he coughed out some blood. He fell down, the life leaving him.

"You shouldn't have done that", a voice spoke up behind them.

Dark Arrow whirled around, only for Killer Frost to grab his bow. She then started freezing it with her powers.

"Didn't think this through, did you?" she asked mockingly.

A blast of blue light shattered the ice around his bow and arms and sent Killer Frost flying back by a few feet. She hit the ground hard and was knocked out.

"She'll be useful too", Darkdevil told Dark Arrow.

"Anyone else wanna be a hero?" Dark Arrow asked as he turned around.

Suddenly, Dinah appeared in front of them, fully suited up as she whirled her bo-staff. They turned around to see a suited up Rene standing there. They looked behind and saw Curtis there too with his T-Spheres.

"They wanted to wait, but I didn't think we'd ever get a better entry line than that", Curtis said and the three charged at the doppelgangers of their mentors.

At the shipping depot, Sara knocked out a soldier before Thawne tripped her and she was sent flying off into the air. Before she could fall, Barry caught her.

"Thanks", she said as Barry put her down.

Another soldier was about to fire at them when Kara threw him off.

Darkdevil dodged an attack from Dinah and kicked her away before smacking away Curtis. Rene rushed them but Dark Arrow kicked him away before Dinah tried to attack again but he smacked her away.

Curtis tried to attack but Darkdevil flip kicked him away. As Dinah attacked again, Darkdevil jumped into the air and kicked her with both feet, sending her flying off.

Dark Arrow blocked an attack from Rene and punched him in the stomach before throwing him away.

Dinah got up, ready to use her Canary Cry. Before she could, Darkdevil divided his club into two sticks and threw one at her. It embedded itself into her throat and she gasped for air. She coughed some blood and fell down, dead.

"NO!" Curtis yelled as he got up to attack Darkdevil. In his rage, he didn't pay attention to Dark Arrow who grabbed him from behind and put him in a chokehold. Curtis tried to struggle but it was in vain. Dark Arrow snapped his neck and let him go. He fell down, dead.

Rene roared angrily and fired at them but Dark Arrow disarmed him by firing an arrow at his guns. He then smacked him with his bow and Rene was down. Dark Arrow notched an arrow when Darkdevil said, "Wait!"

As Dark Arrow lowered his bow, Darkdevil kicked Rene's mask off, revealing his face.

"Oh! Him!" Dark Arrow said in disgust.

"The Captain will decide what to with him", Darkdevil said before kicking Rene out.

Oliver smacked a soldier on the legs and he was down. He turned around and dodged an attack before smacking the soldier down too. Sara hit another with her batons in a rotatory motion and he was out too. Laurel got another with her Canary Cry.

The soldiers were all out. Oliver, Barry, Kara, Laurel and Sara stood together when they noticed a gigantic figure walking out of the shadows. Kara's blood ran cold on seeing it.

"What the hell is that?" Sara asked as she looked at the cyborg with the green, glowing heart.

"Metallo", a horrified Kara said.

It fired a green blast and Kara was hit. She flew back by a few feet and fell on the ground, knocked out.

Captain Hydra, Black Widow, Overgirl and Thawne watched the sight.

Firestorm flew towards it but it grabbed him and threw him away. Firestorm hit a pillar and the impact split him into Jax and Stein who both fell on the ground, knocked out.

Reverse Flash then sped towards them, knocking Sara down. Before Laurel could react, Black Widow wrapped her feet around her and hit her with her Widow's Bite, sending electric shocks through her as she fell down, unconscious.

A flying Overgirl knocked Barry down while Captain Hydra threw his shield which hit Oliver again and knocked him down.

A dazed Oliver tried to take out an arrow to fire at Overgirl.

"Not today", Captain Hydra said as he neared him and kicked him on the face, knocking him out.

Oliver's eyes opened and he felt a pain in his head. He shook his head and it all came back to him. He was tied to a piece of machinery, between Sara and Kara. All of them had some kind of collar on their necks.

"Is everyone all right?" Oliver asked.

"We're gonna have to work on your definition of "all right," Oliver", Sara joked as everyone's eyes slowly opened.

"Yo, Grey, you good?" Jax asked from the farthest left corner.

"It seems my retirement was somewhat tardy", Stein said from the farthest right corner.

Suddenly, they heard slow clapping. They looked up to see the Emperor looking down on them from a platform.

"Well, here we are", Emperor Stark said with a chuckle, "It's nice, right? You fight the bad guys, tie them up for the police, save the day and go home. But this time, you're the ones tied up.

"This is fun for me", Thawne said to Barry as he walked up next to Emperor Stark, "Not so much for you. All the times you've killed me, and now here all I have to do is kill you once."

"Enough! Thawne!" Captain Hydra's voice came from the other side. Everyone turned to look in the direction as Captain Hydra, Black Widow and Overgirl walked towards them.

"Enough!" the Captain said again.

"Hey, you might want to listen to him", Alex said to Thawne.

"We know that if you wanted to kill us, you wouldn't have put these dog collars on us first", John said.

"Now I know what it feels like to hate myself", Kara said as she looked at Overgirl with disgust.

"This is interesting", Dark Arrow said as he walked in with Darkdevil.

"Very", Darkdevil added.

Both of them did not have their masks on. Everyone was horrified to see Matt's face there.

"Matt?" Oliver said in horror.

"Yeah", Darkdevil said as he turned to Oliver, "But I'm nothing like the weak Matt you know. After you, I'll kill him."

"You can try", Oliver sneered.

"Well done everyone", Emperor Stark said with a smirk, "Good job guys!"

"It wasn't really a problem", Overgirl told him. Suddenly, she felt weak and fell down.

"Hey", a concerned Dark Arrow said as he knelt close to her.

"Uh!" she breathed heavily, "The pain, the pain. I don't know how much longer I can bear it."

"It's all right. It's all right", Dark Arrow assured her with a smile as he put his arms around her while the heroes watched In disgust, "You're gonna be all right because we found her. We found her, and now we have her."

The two looked at Kara as he said that.

"I love you", Dark Arrow then said to Overgirl as she turned back to him, "Now, very soon, this nightmare will be over, and I'll take you home. So stand."

Her face hardened with resolve and using all her will power, she managed to stand up again as the two turned to the Emperor.

"S.T.A.R. Labs is secure", Darkdevil said to him.

Barry growled angrily, "If you hurt my friends-"

"We did hurt your friends", Dark Arrow said with a cruel smirk.

"We really enjoyed hurting your friends", Darkdevil said with a chuckle, "They got the Devil's punishment."

"Are they alive?" Oliver asked.

"Some of them are", Darkdevil said with a cruel smirk.

"Can't say that for Mick Rory, Dinah Drake and Curtis Holt", Dark Arrow revealed and everyone felt like their hearts had been hit by a hammer.

"I'm going to kill you all in ways that will hurt", Oliver growled.

"And you will beg us for mercy", Sara growled too.

"Because you're all pathetic cowards", Laurel added.

"We need your Kara's cooperation", Emperor Stark said as he walked down, ignoring the threats made by the three, "Well, we don't need it but it would be preferable for her to give it."

"For the time being, you are more valuable as leverage", Captain Hydra told them.

"What do you want my sister for?" Alex asked them.

"To save my life", Overgirl said.

Turning to Kara, she said, "That's your little mission statement, isn't it? Help people, save lives. Well, now's your chance."

"The General is dying", Thawne revealed.

"Her blood", Alex said in realization, "She's been exposed to too much solar radiation."

"Yes, like Icarus, I flew too close to the sun", Overgirl said.

"But we can save her", Captain Hydra said.

"We're going to save her", Dark Arrow said, "All we need is a new heart."

"And, luckily, on this planet, we found the perfect donor", Black Widow said as she looked pointedly at Kara.

"You stay the hell away from my sister", Alex roared angrily.

"Mmm. Such loyalty", Overgirl said with a smirk, "My sister tried to kill me."

"Why did you steal the Prism?" Roy asked.

"So you could duplicate a red sun, weaken Kara, and cut into her, right?" Barry asked as he realized their reasons.

"Can't make an omelet with invulnerable eggs", Overgirl said.

"Hey", Oliver growled as the Emperor and Dark Arrow looked at him, "I'm gonna kill you. I'm gonna kill all of you."

"We'll see about that, Robin Hood", Emperor Stark said with a smirk.

They all then walked away as Emperor Stark waved his hand, "Bye bye."

They heard metallic footsteps and turned to see Metallo who stopped and fired a green beam at them.

"Where are you going?" Thea asked Felicity.

"It's been a while since Mick and Caitlin told us to go?" Felicity said.

"But I don't think it's safe yet because they haven't told us to come back", Thea pointed out.

"We can just go and ch-"

"Shut up!" Thea said.

"No I will not-"

But Thea raised her hand.

"No, seriously", Thea said, "Shut up. I heard something."

The two walked down the hall to see some Hydra soldiers. One of them carried Rene into a cell and locked him in there.

"We're not alone", Felicity whispered in horror.

The two fled down the hall to find a safe place to hide where the Hydra soldiers won't find them.

Oliver, Barry, Sara, Laurel, Roy, John, Alex, Jax and Stein woke up and got off the ground.

"Kara", Alex said as she got up, "Where's Kara?"

Turning to the others, she said in a concerned tone, "They're gonna kill her."

"It's ok", Sara assured her, "We're gonna get her back."

"We need to figure out where we are first", Oliver pointed out.

Looking around, Jax said, "Yeah, about that."

"This is somewhat disconcerting", Stein said.

Everyone looked around. They were in a weirdly lit area with gates and iron fences. Around them were prisoners in uniforms.

Oliver's attention was attracted by a man whose entire upper body was wrapped in chains and he was naked from the waist up.

"I don't think this is our earth", Sara said, making him focus on what was important.

"We're on Earth-X", a horrified Laurel said.

R.I.P Mick Rory, Dinah Drake and Curtis Holt. I didn't like killing any of them. Mick is actually one of my most favorite Arrowverse characters and Dinah and Curtis have been getting on my good side too lately.

But these are ruthless workers of Hydra who will kill anyone who stands in their way, except scientists as Hydra has a thing of recruiting any scientist with skills- hence why Harry and Caitlin are alive. The reason for Rene's survival will be explained in a later chapter.

I'm sorry I killed them off. I really am. But this needs to be a realistic story and stakes need to be raised.

A joke to lighten the dark mood. I have finally figured out what the writers smoak. Got it? Okay.

Please review. I always appreciate your feedback.
