It absolutely sucks that this is the last part I will be writing for this book until the seasons end. I think I'm stopping on a good note, though. Of course, that's if a cliffhanger can be called a good note . . .

Anyway. Tensions run high in National City, and Kara finally comes face to face with her big bad of the season, and she doesn't come alone. Sadly, the outcome remains the same.

Enjoy!

"Samples from the remains of the victims confirm," Winn turned away from the news grimly. "They were killed by heat vision."

"It really is a Kryptonian doing this," Amaya swallowed.

"Yep," Winn nodded. "And Morgan Edge had nothing to do with it."

"Well, at least it's not related to the guy with the laser gun who went after Lena," Felicity pointed out.

"Nope," Laurel shook her head. "Just some guy Edge hired to try and kill him."

"And Harry and Iris were just in the crossfire," Caitlin sighed.

"So he thought he could get away with killing her and blame it on the Kryptonian?" Stein asked.

"See why we don't like him?" Malcolm snorted.

"Just like Coville said," J'onn said. "'Work of the Beast.'"

"That's not creepy at all," Cisco shuddered.

"Coville strikes me as a fanatic, not a prophet," Slade frowned.

"The two don't have to be mutually exclusive," J'onn shook his head. "He said this. The Beast would come. She would mark the city, and then She would take it. I think it's worth pushing through the noise here to see the truth."

"Well, the moment you start believing in something is the moment you give your power away," Kara huffed. "I'm not gonna give away mine. So what we know about this Kryptonian is that she's a pretender. I beat Kal down to the ground when I had to. I'll beat her down, too."

***

Lena looked down her phone when it rang, and frowning, she picked it up. "Hello?"

"I heard you were attacked by someone who tried to make it look like it was perpetrated by that thing that's leaving those alien marks," Edge said, and Lena growled, making Harry look at her in surprise. "That's awful! Awful! I mean, it's Christmas!"

"Morgan, you are a vile, despicable scrooge who's gonna die alone and in prison," Lena spat.

"Well, gotta go," Edge said cheerfully. "Christmas party!"

Lena hung up angrily, and Harry raised an eyebrow. "The Grinch?"

"Yeah," Lena seethed.

***

"OK, how hard can it be to track down a Kryptonian going around killing people?" Nate asked later, looking up from his work.

"She probably disguises herself like Kara does," Amaya answered.

"And we don't even know what she looks like," Caitlin pointed out.

"We have a lot to do," Alex sighed, rubbing her temples.

Kara was walking down the stairs when her phone rang, and frowning, Kara picked up. "James?"

"Someone just tried to heat-vision Edge," James cut to the point, making Kara freeze. "He's calling a press conference."

"Is he hurt?" Kara demanded, hurrying down the steps.

"Sadly, no. Of course this guy has a lead-lined panic room in his office. But whatever's out there wants him dead. He just got lucky."

"I'm on it," Kara seethed, hanging up and heading for the balcony.

"Kara?" Oliver walked over, frowning. "What happened?"

"The Kryptonian attacked Edge in his office," Kara answered as the others started gathering around.

"Oh . . . no," Winn blinked. "No? No, that's bad. That's objectively bad."

"I wouldn't lose any sleep," Malcolm snorted.

"It doesn't matter who the target was, they're just killing whoever they want," Kara shook her head.

"We're doing everything we can to track them," J'onn assured her.

"I'll head to Edge's office with some of the others, we can see if they left behind anything we can trace," Alex added.

"No," Kara said firmly. "No, I'm tired of playing hide and seek. The longer we wait, the more people are gonna die."

"So what are you thinking?" Sara asked as Kara headed out to the balcony.

"We do it their way!" Kara answered, shooting into the sky.

Winn sighed. "Well, that's comforting."

***

Kara flew over National City, and when she reached CatCo, she fired her heat vision, tracing the House of El crest into the roof. She looked down in satisfaction, then smirked. "Your turn."

***

"I can't believe this guy," Harry grumbled as he watched the news.

Lena scowled as she watched Edge work the press. "I'm sure that it's not the first time that a woman who's gone crazy has attacked a powerful man. I'm fairly certain it won't be the last."

"Are you saying Supergirl attacked you?" one of the reporters asked.

"I'm saying I can't say it wasn't Supergirl," Edge responded.

"Sociopathic cockroach," Lena snarled angrily, turning and walking towards the elevator.

"I agree with you, and I just met the guy," Harry snorted, walking after her. "But look, neither Danvers nor Queen are gonna let him get away with this."

"Or Slade, or Malcolm, or Laurel," Lena smirked.

"Nope," Harry shook his head. "He'll get what he deserves. If it's one thing I've learned working with Allen, it's that they always do."

Lena nodded, pressing the button for the ground floor. "You know, your plan today probably saved my life."

"Well, right place, right time," Harry shrugged.

"I still think that means I owe you a drink."

Harry raised an eyebrow, folding his arms and looking at her. "Ms. Luthor, are you asking me on a date?"

"It's a thank you drink," Lena corrected, though there was a slight blush in her cheeks. "And please. It's Lena."

Harry nodded thoughtfully. "All right, Lena," he emphasized her name. "I'll take that thank you drink. Been a heavy day, after all."

Lena grinned as the doors opened. "To heavy days and Christmas, then."

Kara smiled fondly as she watched Mon-El and Imra in the training room, then turned when Sara walked up to her. "Hey there," she smiled.

"Hey," Kara smiled. "What's up?"

"Well, I realized I never really asked," Sara leaned against the wall. "Are you OK?"

"What?" Kara blinked. "Yeah, Sara, I'm fine."

"OK," Sara nodded. "It's just that it can be argued that you had the roughest of all of us doing the Earth-X crisis, and then when I heard that guy had come back not long before it . . . I just wanted to make sure."

"Yeah," Kara nodded, clearing her throat. "It was . . . really tough at first. It was a hard day."

"Laurel told me all about that," Sara nodded. "She was quite smug."

"She would have been," Kara chuckled.

Sara bit her lip, looking down. "She also said you gave Slade your necklace."

"I did," Kara confirmed, nodding. "Do you still have a problem with him and Malcolm?"

Sara sighed. "It's just . . . I didn't think I would ever be able to associate either of them with the word 'hero' after everything they did before Earth-X. But after Earth-X, seeing how they truly care about you . . . it's getting easier to see them that way." She looked up at Kara. "Besides, I don't have to deal with them as much as you do. It's your opinion that matters most to them. And Ollie's. But probably yours."

Kara smiled. "It's hard not to laugh when they do the wizard/magician bicker in the middle of an op."

"They do?!" Sara's eyes widened.

"Yeah!" Kara laughed. "And they did it while Oliver was trying to talk to a bad guy."

"Oh, my God," Sara closed her eyes. "They are literal children."

Kara was still giggling when she heard a triumphant shout from below. "Kara!" Winn quickly ran up the steps with Oliver and Alex behind him. "The Kryptonian responded!"

"How?" Kara's eyes widened.

"Just showed up right where you left your mark," Winn shrugged.

"And waiting for you," Alex nodded.

Kara slowly nodded, then turned around. "Hey," Sara reached out and took her hand. Kara turned back, raising an eyebrow, and Sara swallowed. "You may be Kryptonian, but so is she, and you haven't faced her before. Don't take any chances. At least take some help."

"When all of you trained against me," Kara began.

"We didn't have a Kryptonian fighting with us," Sara interrupted. "Kara, I know this is your universe, and ignore this if you want. But none of us fought to get back to you just to see you get killed here while we stood by."

Kara swallowed, then nodded jerkily. "I'll need some of the Legends."

"You've got them," Sara nodded back.

Kara took a deep breath and turned, heading towards the staircase. "Kara," Oliver walked after her, taking her hand.

"I've got to do this, Oliver," she told him.

"And I'm not gonna stop you," Oliver shook his head, stopping her. "Look . . . remember when Edge was first a problem? When we were worried about Bloodsport?"

"Yeah," Kara nodded.

"You told me you didn't want to be Kara Danvers. You focused on being Supergirl. You tried to get rid of your humanity." Kara ducked her head, still embarrassed she had once thought that. "Forget being human," Oliver told her, and Kara looked up, shocked. "This isn't a human you're facing," he explained. "This is a Kryptonian. This is an alien, and you may have been raised with humans, but you're alien, too. So forget being human for this fight. Be cold, and be Kryptonian. Because for some reason, this Kryptonian?" He swallowed. "She scares me, Kara. So please, if it means you win . . . be alien."

Kara nodded, reaching up and kissing him. "I'll come back," she whispered. "I promise."

Oliver nodded, squeezing her hand, and Kara walked down the stairs. "Barry!" she shouted. "Ray! Nate! Jax! Lily!" The five ran from where they were speaking with the others, and Kara swallowed. "Are you five with me?"

"Wherever, whenever," Barry nodded instantly.

"We got your back," Nate nodded.

Kara took a deep breath. "Then suit up."

***

Barry skidded to a halt on top of the CatCo building, setting Nate down beside him. Ray and Jax flew to hover above them as Kara landed in front of them. "Guys," Ray swallowed. "We're in position."

"And this Kryptonian is definitely not playing nice," Nate eyed the brunette woman at the other end of the building, clothed entirely in black, including the mask concealing her identity.

Kara walked forward, sizing up her opponent. "So you're supposed to be the Devil?"

"The Devil isn't real," the Kryptonian said, her voice warped.

"Then who are you?"

"I'm from the time before fathoming," she answered. "Born to cleanse the scourge and deliver the awakening. I am Reign."

"And she will reign," Barry whispered, remembering Coville's words.

"How did you get here?" Kara asked.

"I survived Krypton's death," Reign answered. "Sent here upon its destruction."

Kara frowned in confusion. "If that's true, then where have you been?"

"Dispensing justice."

"By terrorizing people? Killing people?"

"This world has sunken into chaos and sin," Reign looked around. "Too many have eluded judgment."

"We're not gonna let you hurt anyone else," Kara scowled, walking forward. "Surrender now before we make you surrender."

Reign just smiled darkly, walking forward to meet her. "So full of hubris, just like the righteous Kryptonians who feared my makers, worshiping false gods as they watched our planet suffocate by shame and burn from memory. Stand down, or I will make you join them in their purgatory."

Kara lifted her head defiantly. "I'm not going anywhere."

Reign scowled. "Then I will dispense my justice on you."

"Take your best shot," Kara challenged.

Before any of the Earth-1ers could even blink, Reign blurred, and Kara was suddenly hurtling through the air, Reign flying after her. "Right," Ray blinked. "Kryptonian . . . super speed."

"Flash, go!" Nate told the speedster.

He raced off, following the aliens through their fight.

***

A few buildings away from CatCo, a Christmas party was interrupted by Kara and Reign flying in through the windows, exchanging blows over the conference table. Reign shoved Kara through the refreshments' table and into the Christmas tree, knocking both over, the Christmas tree lights flickering. Kara was yanked up by Reign, and she swerved to try and avoid Reign's fists as the lights started flickering behind her.

Barry suddenly sped into the room, ramming into Reign from behind. Reign staggered slightly and spun around, and Barry stumbled away slightly, too. "Super strength, too," Barry winced. "OK. Right."

Reign sneered and turned to punch him, but Kara grabbed her arm and spun her around to punch her. Reign ducked and reached out, grabbing Kara by the throat. Her eyes bugged, and she choked, trying to get Reign off her.

Ray flew in through the window and aimed at Reign, firing a blue blast of energy at her. Reign twisted and let it fly past her, but it distracted her enough to lose her concentration. Kara spun Reign around and tossed her over the conference table, and Reign slid all the way down and onto the ground. When she stood up, Kara flew over, grabbed her, and flew her through the roof out into the night. "Firestorm?" Barry shouted.

***

Jax swerved in midair to avoid getting hit by the Kryptonians, and he turned in midflight. "They're heading for the waterfront!" he called.

"It looks like a shipping dock," Lily added.

"With a lot of heavy stuff to throw around," Jax muttered.

"Exactly."

Jax nodded and flew after the Kryptonians, seeing Barry speed out of the building and Ray fly out after him.

***

Kara rolled onto the ground among the shipping containers, wincing. She heard Reign take off again and rolled onto her knees, looking to see where she had gone.

Her eyes widened when she saw Reign place her hands on two shipping containers and push, rocking the dock and shoving them towards her. Kara fell back on the ground as the dock rocked, raising her arms to block the containers heading for her.

Lightning zipped between the containers, and Kara gasped when she found herself on top of one of them. "You OK?" Barry asked in concern.

"Yeah," Kara took a few deep breaths before launching off the container and grabbing Reign, flying back to the city.

***

"Guys, they're heading your way again!"

"Copy that!"

"On our way!"

Oliver paced anxiously around the D.E.O., listening to the comm chatter as Winn, Cisco, and Felicity monitored everyone. "No one's damaged," Felicity said.

"Come on, guys," Sara clenched a fist. "You've got this."

***

Kara and Reign crashed in the middle of a busy street, creating a small crater in the asphalt and tossing a car through the air, making it crash into the ground and explode. As civilians panicked, Harry and Lena ran onto the scene, eyes wide. "Get back!" Harry shouted. "Get back!"

"Everyone, get back, now!" Lena yelled.

Kara was panting as she punched Reign with everything she had, but Reign was strong, stronger than any opponent she had ever faced. She always stood back up after she was hit, and her punches never diminished in strength.

Reign jumped into the air and brought her fist down hard, ramming her fist into Kara's head. She yelped and fell to her knees, gasping as she felt her world spin. When she looked up, she saw a blonde girl starting to move from behind a car. "Get back!" she held up her hand. "Stay back! Stay back!"

"Supergirl, look out!" Nate shouted.

Kara tried to turn, only to yell in pain when Reign hit her in the back of the head with something metal. "Supergirl!" Ray yelled.

Kara reached up to her head, feeling something sticky on her fingers. When she looked down, she found her fingers stained red. "Distract her," she whispered.

Barry sped in front of her, and then he was speeding around the two Kryptonians, the civilians letting out exclamations of shock. Reign glared around, following the speedster, and when he launched a lightning bolt at her, it did nothing to phase her. Barry skidded to a stop, and Reign shot her heat vision at him, ruby red instead of bright blue. It hit Barry in the chest, and he went flying down the street, landing with a thud.

***

"Barry's been hit," Cisco blanched.

"Guys, look at this," Iris looked up from the center console, eyes wide. "They're broadcasting it!"

The others gathered around to see live coverage from helicopters, and Oliver swallowed when he saw Reign glaring after Barry, Kara struggling to her feet. "Oh, my God."

"Come on, Kara," Thea whispered, crossing her fingers anxiously.

***

As Reign moved to go after Barry, Kara surged up from her crouch and punched Reign in the shoulder. She spun around and blocked the next one, grabbing the collar of Kara's suit, hauling her off the ground. The black-clothed Kryptonian smirked at her before headbutting her hard, dropping Kara to the ground. She stomped hard on Kara's chest, making her retch.

Firestorm flew down next and lobbed a fireball at Reign. She backed up, surprised by the onslaught, and as Kara weakly rolled onto her stomach, Firestorm flew to hover above Kara, throwing more fireballs. Reign stepped back, narrowing her eyes, and before Firestorm threw the next fireball, she blew hard.

Her freezing breath hit Firestorm in the chest, catapulting the metahuman out of the sky. The metahuman crashed onto the roof of a small building nearby, and a burst of flames signaled Firestorm separating back into Jax and Lily. Barry rolled onto his knees, took a deep breath, then sped over to check on them.

Reign smirked triumphantly and turned back to Kara, only to be met by metal in the chest. Kara had managed to stand and grab the same metal rod Reign had used on her, hitting the other Kryptonian with it. She watched Reign smash into the crashed car, then collapsed again, hacking and coughing, her breath ragged.

***

Papers went flying from agents' desks, and everyone spun around as a trail of lightning left, leaving Jax and Lily on the ground, both of them groaning in pain. "Lily!" Stein ran over, followed by Caitlin. "Jefferson!"

"What happened?" Zari demanded.

"Blew us out," Lily coughed as her father helped her up. "She's really strong."

Sara swallowed, turning back around. "Ray, Nate, Firestorm is out of the fight."

"Oh, God," Felicity whimpered as Slade and Malcolm exchanged startled glances.

***

"Ray," Nate said from where he stood on top of another building, looking down at the feebly stirring form of Reign. "She's waking up."

"I'm on it," Ray flew down.

Nate's eyes widened when the Kryptonian's heat vision shot again, and Ray went tumbling through the air. "Ray's been hit!"

"Barry, get him out of there, now!" Sara yelled.

Before Ray hit the ground, Barry zoomed by again, and Ray was gone. Nate jumped off the building and landed on the ground in steel form, approaching Reign cautiously. He stopped when he saw her rip a door from the car, dragging the flaming object on the ground. Confused, he walked away from her, only to freeze when he saw Kara stagger to her feet. "Supergirl, no!" he shouted.

His warning came too late; Reign swung and threw the car door at her, knocking Kara's feet from out of her. Kara tumbled head over heels, and Reign shot her heat vision at her, flinging her high into the air, back to the top of the CatCo building. He saw something clatter on the ground, and he ran over, looking through the rubble as Reign took off. He swallowed when he found what he came away with. "Supergirl's comms are down." He looked up, taking a deep breath. "Reign's going after her again."

***

Sara ground her teeth, turning away from where Felicity and Zari were helping Ray take off his suit, the man himself barely keeping upright. "Where are they?"

"Back on top of CatCo," Nate answered. "I can't get up there. Guys, she was bleeding, badly."

Oliver turned as white as a sheet, and Sara looked around desperately. "Anyone have any ideas?"

Everyone seemed too stunned to offer anything.

***

Kara's breath left her when she collapsed on the roof of CatCo, slumped on the ground, everything hurting. The roof shook as Reign landed shortly after. "I'm gonna kill you," she snarled, storming over.

Kara's breath was uneven as she struggled to her knees. "You don't – " She coughed, barely holding herself up as she looked up at Reign. "You don't scare me."

"You're no god," Reign sneered, standing over her. "Just as I'm no devil. All I am is truth." She leaned down and grabbed Kara by the collar of her suit, hoisting her into the air.

Barry sped onto the rooftop as Kara choked, and he gulped. "I can't do anything without hitting Supergirl, too."

"And judgment," Reign continued.

Barry's eyes widened when Reign stepped onto the edge of the roof, dangling Kara over the edge. He sped off, stopping by Nate. "Hang on," he said, grabbing his friend and speeding off.

***

"And death," Reign sneered. "And I will reign!"

With that, she let the hero go, watching in dark satisfaction as Kara tumbled through the air, dropping several stories to the ground below.

Except she didn't smash into the pavement. Barry sped Nate just below her, and he quickly turned into steel and held out his arms, catching Kara before she crashed. The force of her fall made him fall to his knees, but he cradled her close, his eyes wide as Kara went completely limp, her head lolling. "Supergirl?" he asked helplessly as civilians ran to see. When she didn't answer, he looked up at Barry. "Get her out of here!"

Barry carefully took Kara in his arms, then sped off again. Nate stood and watched him go, dread making his heart heavy.

Had they really just saved Kara from the Nazis only for her to nearly be killed by one of her own kind?

***

Radio silence. Complete radio silence. "Does anyone copy?" Sara finally lost her composure, yelling and making Zari flinch.

For another second, there was silence. Then there was a loud cracking sound, and suddenly, Barry was in the medbay behind them. "Help her!" he yelled, eyes wide.

And for the first time, Laurel screamed in horror, clapping her hands over her mouth as Cisco dropped his tablet, eyes blown wide as he took in the completely still Kryptonian Barry was lowering onto the bed. Everyone else was just as frozen, Sara looking at Oliver, the man himself even whiter.

Finally, Alex started yelling for the medical team, running to her sister, Caitlin shaking herself out of her stupor and running after her. Barry ran off again and returned a second later, Nate not even stopping to catch his breath before he ran to the doorway of the medbay, waiting for the medical staff to run in and join Alex and Caitlin before turning to Oliver and Sara as they ran over, the rest of the heroes running to check on Kara. "She just dropped her right off the building," he swallowed. "She fell unconscious right after I caught her."

"She's a monster," Thea covered her mouth, tears filling her eyes as she watched Alex and Caitlin work. Felicity was already crying, Dig trying to comfort her as he watched, stunned speechless. "She's a complete monster!"

One of the medics looked up. "She's crashing," he told Alex.

Another swallowed hard when she saw her vitals on screen. "She's crashing!"

Alex tried to calm her breathing, and Caitlin looked up. "We need to intubate," she ordered. "Hurry!"

The medics ran around to follow her orders as Mon-El and Imra ran in, joining J'onn and Winn with the others. Amaya swallowed as she watched Alex and Caitlin do their best not to panic in front of everyone. "Has she ever been hurt like this before?"

Oliver swallowed hard, thinking back to Cadmus. "Not by a Kryptonian."

"She came back from that, kid," Slade put a hand on his shoulder; how tightly he gripped showed just how worried he was, too. "She can come back from this."

"She's strong, Ollie," Sara nodded, though tears were glittering in her eyes, too, as she tried to stay strong for her friend. "She can do this."

"She'll be OK," Imra agreed confidently, though there was worry in her eyes as well.

Oliver just swallowed and nodded, reaching out. Sara took his hand, squeezing tightly, understanding the man was finding it hard to speak, and they watched Alex and Caitlin fight to save his fiancée's life. "Come on, angel," he whispered, his voice choked with tears. "Fight!"

"Stay with us, Kara," Alex begged.

But Kara didn't move as Caitlin nervously watched the monitors beep ominously. She had to pull through this. She had to. Otherwise, they might lose every hero from Earth-1 when they went on a rampage to kill Reign themselves.

"Stay with us!"

To be continued with "Legion of Super-Heroes" when Seasons 6 and 3 of Arrow and Supergirl conclude!

I really hate wanting to stop, but I do not want to write something in an episode that has aired and dig myself into a hole I can't get out of later. I want you guys to understand that I absolutely love this series, and I do not want to make a mistake like that.

But, don't worry - I'm not on hiatus on writing in general. Because now that this episode is done, I finally get to start on my second original SuperArrow book, "The Daxam Four!" I'm hoping to get the prologue up before the end of the weekend to officially announce its starting, so stay tuned! I'll see you whenever Supergirl finishes!

Long live the OTPs!
