Karry Universe

Disclaimer: I own nothing.

Note 1: Once again I must give credit where it's due. While this chapter was not actually inspired by someone like last chapter was, my sort-of OC (a DC original but a new human persona) was named through a conversation a reviewer had with my beta. I know that sounds weird, but well that's what happened. So Silver-Infinite you have inspired me and my beta in ways you will never know. Thank you, and I believe you will really enjoy this chapter.

Note 2 (IMPORTANT): Later today, I don't know what time, my beta, Terrance Sigma, is posting his part of the crossover into Karry Universe. The chapter is completely hundred percent canon here taking place after the Legends of Tomorrow chapter. So go read it and make sure to REVIEW.

To the Guest Complaining about the picture change: it's a picture. It's no different than cover page for a book. Yes I said it looked kind have like a wedding picture but not that it was in story. It's obviously a picture of Melissa Benoist and Grant Gustin at some award show or something. It's not in story, it just a nice picture of them. It's staying up so let it go.

Sisters – Revenge, Revelations and Resolutions

Caitlin took a deep breath as she got out of the car. She had parked at her apartment building after a long day at the lab. It was sad to know Ronnie was not waiting for her, or at the labs to come home to her. "It's time travel I can be back in five seconds," Caitlin mumbled agitatedly under her breath as she opened the trunk. How could she blame him though? Traveling through time and saving the world was something anyone would long to do. She had married a superhero after all but she had never expected him to actually leave her like this. Leave the Justice League weakened with a threat looming on the horizon.

But life seemed to move on as everyone went back to the day-by-day routines. Barry, Cisco, and Winn were having some type of boys' video game night – Barry had apparently gone on a bit of a video game buying spree and bought some rare old system the boys were excited about, along with the newer systems. Kara who didn't like videogames, was going to be coming over to her place for a girl's movies night.

Caitlin removed the supplies she had bought from the trunk – basically a massive amount of junk food – and closed it. "Having a party?" she heard a woman ask, and Caitlin looked around. She knew that voice. "Of course I wasn't invited. Why would you invite me? We've only known each other for our whole lives."

"Crystal…" Caitlin stated to the figure in the shadows.

"Then again, I guess we never have gotten along. You were always the perfect one. You could do no wrong. Now what do you have? I heard you're married. Didn't invite a single family member, but oh well. You did abandon us after all. You have a good job at a lab. Your life is so perfect." She didn't speak with sarcasm; in fact, she didn't speak with any sort of tone to her voice.

"Crystal, this is not funny," Caitlin stated, annoyed.

"My life though? I had to move back in with mom. Mom, Caity. You know how she is!"

"Maybe you should have tried harder."

"But then something funny happen. There was an explosion and then I suddenly got very… cold, shall we say. I guess I can thank you for that." The figure walked out of the shadows and forced Caitlin to take a step back. The other woman looked exactly like her only her hair was white and her lips were blue.

"Crys!" Caitlin said, using her sister's nickname in her shock but knowing what had happened. "I can help you. My lab… we can help you."

"Help me? I don't want your help!"

"Crys…?"

"I never liked that name," Crystal said, ice appearing in her hands. "The name is Killer Frost now." Crystal shot ice at Caitlin, who barely had time to dodge it. Dropping the bags, she went to run, but Crystal formed an icy layer under her feet which she slipped on.

Crystal went to throw more ice at Caitlin, but Supergirl appeared, moving in the way and blocking the ice she threw. "Shouldn't you be in Arendale, Els…." Kara's voice trailed off as she finally got a good look at the meta attacking Caitlin. "What?!" Kara asked, seeming stunned as the icy meta turned to run. Kara decided not to go after as she turned to her friend. "Are you okay?"

"I think my ankle is twisted," Caitlin moaned as Kara leaned next to her. "So glad you were coming over."

"Caitlin… that meta looked just like you," Kara said.

"She should," Caitlin said. "That was my sister." Kara didn't say anything stunned as Caitlin continued "My identical twin sister."

Kara just stared dumfounded at Caitlin as Barry in her head asked: what?!

-Superflash-

Lois and Clark were in the living room with their kids. The two kids were engrossed in some cartoon as the adults stayed silent, enjoying the family company together. "Mommy," Jason finally spoke up, looking away from the TV. "Why can't we have a dog like Krypto?" This must have been something on his mind for a while. One of his friends at school had recently got a puppy and it had started the boy thinking.

"Because Krypto is the only Kryptonian dog on Earth and any other dog you would have to be really careful with," Lois answered.

"And Krypto belongs to Kara," Clark added. "But she brings him around a lot."

"Not the same," Jason moaned pouting.

"There's nothing you can do about that," Clark said, messing up his son's hair and noticing the conversation had gotten Ella's attention away from the cartoon too.

"But if Krypto had puppies the puppies would be like us, right?" Jason asked.

"Logically speaking the puppies should take powers the same way you and Ella did," Clark said thoughtfully, wondering where this was going. His son was very bright. At nearly 6 he knew both English and Kryptonese and did well in his classes at school.

"So we can have one of those," Jason said and Ella jumped up excitedly.

"But Krypto does not have babies," Lois said. "For that to happen Krypto needs to find a female dog and make babies."

"So if Krypto does have babies we can have one?" Jason asked as Ella started giving pouting too.

Before Lois could answer there was a knock at their door. "Who is it?" Lois asked her husband who used his x-ray vision on the door.

"Lucy," Clark said jumping over the couch to go grab his glasses.

"Be good kids," Lois whispered the usual order when someone who did not know their secret stopped by so the kids knew not to use their powers. "Lucy," Lois said as she answered the door. "What a surprise."

"Hi," Clark said from the kitchen, his glasses already on. "What brings you all the way to Metropolis?'

"Oh nothing much," Lucy said quickly looking around; she had been so certain when she had gotten on the plane. She needed to confront her sister. To let her sister know she knew her secret, but now in their apartment she wasn't so sure where to start.

"Mommy," Jason complained as he never got an answer.

"Kids say hi," Lois said.

"Hi," Ella said, waving at Lucy.

"Aunt Kara's friend," Jason said happily.

"No kids, she's my sister," Lois said, feeling bad as Jason called her sister 'Aunt Kara's friend'. The two had never had much contact with their aunt and most of it had been through Kara lately so Lois could see the mix up.

"I guess I am Aunt Kara's friend now too," Lucy said, dismissing this, not getting jealous over Jason's words like she would have months ago.

"Mommy. Krypto!" Jason tried to bring the conversation back.

"What about him?" Lois asked, forgetting the conversation they had just been having.

"If he has puppies can we have one?" Jason asked.

Lois shook her head not wanting to deal with this right now. "I don't know. Ask Aunt Kara," Lois said.

"Yes!" Both Jason and Ella cheered as they ran into their shared room to plan.

Clark stared as his kids disappeared. "You do realize you just guaranteed that if Krypto has puppies we're getting a dog right?" Clark asked.

"Maybe Kara won't say yes," Lois said and Clark gave her a look and Lois nodded her head. "Yeah your right. That's not happening. Well maybe Krypto won't have puppies. Or maybe we're getting a dog." Lucy laughed at the exchange. "So just a drop by? You live kind of far for that?" Lois finally asked her sister.

"Well there was a reason why I came here," Lucy said making sure the door was closed before turning to Clark. "You can take off the glasses."

"I can't see without them," Clark said giving an unconvincing laugh.

"Yeah right, Superman," Lucy said, making Lois and Clark take a step back and start to fake laugh even worse than Clark's previous laugh.

"You think? I'm not…" Clark said nervous.

"My boyfriend Ray, also known as Atom, has a big mouth," Lucy said making Lois and Clark look at each other, knowing the game was up.

Clark took off his glasses and put them down. "Remind me to teach Ray how to keep a secret,'" Clark said annoyed.

-Superflash-

Oliver and Thea were fighting a group of thugs. "How do we get ourselves into this?" Thea asked as she took out what she thought was the last one and smirked at her brother.

"Well, we are…" Before Oliver could answer, from the corner of his eye he saw another thug coming at him. Before he could turn around and get ready to strike, an arrow flew past him and landed in the man chest. He toppled over as Oliver demanded: "Where did that come from?"

"Turn around," the two heard a voice say and Thea and Oliver turned to see another masked female not far off. Bow still in hand. She had long blonde hair in a ponytail and wore a green mask. She wore a green shirt that had a light green arrow on it pointing up. Her pants were also dark green and had light green running across the side. She wore black boots and over her shoulders was a quiver with arrows in it. "Arrow" she said, stepping closer but Oliver took his own arrow out and pointed it at her.

"Who are you?" Oliver demanded. Even though this girl had just helped them, he did not trust her. He never trusted newcomers.

"You can call me Artemis," she said, a cock attitude noticeable. "And I want to be trained by you." Oliver barely lowered his bow but turned his head to looked at his confused sister.

-Superflash-

"Your sister?!" Cisco said in shock. After Kara had saved Caitlin, the two had gone back to the Superflash cave where the boys had met up with them. "We've known each other for how long? How did I not know you have a sister?"

"You know we could use some of the technology here for our video game system," Winn said suddenly, clearly on a different topic and making everyone look at him. "Oh sorry, I'm not use to Superflash stuff yet."

"Wait, our video game system?" Kara asked looking at Barry. Care to explain?

Well as we were playing we got to talking about how cool it would be to make our own system and our own games. It's nothing.

Kara raised an eyebrow at her husband but decided this was better to discuss later. "Caitlin, I do think you need to explain just a bit," Kara said turning to her friend. "Why didn't any of us know you have a sister?"

Caitlin shrugged noncommittedly. "We were never close," Caitlin explained, looking straight ahead. "Especially after our dad and little brother died when we were young and our mom was just… well, cold is the best word. We were on our own basically and I worked hard to get a better life. Got myself scholarship, graduated from a good college ahead of schedule. Got my job here. Cryst… Well, the last I heard she had failed college. She never worked as hard as me and I just drifted away from my family, concentrated on my life and new friends."

"Well, one of your family is now a meta who tried to kill you," Cisco pointed out. "Why?"

"She blames me, I guess, for her life," Caitlin said, remembering what her twin had told her before attacking her.

"Well I could track her," Barry pointed out.

"How?" Winn asked.

"Same way we tracked Livewire, only instead of looking for electrical readings, I'll look for cold ones," Barry said, going to the computer and showing Winn what he was doing. Tracking unusual cold patterns in the city and then nodded to the readings. "She's downtown."

Barry was about to go and put his outfit on but one thought from Kara stopped him. "Caitlin," Kara said. "This is your sister. What do you want us to do here?"

Caitlin took a breath. "I don't know," she admitted, a little worriedly now. "We can't allow her to hurt anyone."

"Especially you," Cisco added.

"But I don't know if I could lock her in the pipeline or in the DEO." Caitlin said.

"Well, you know there is a meta human section of the jail we tend to forget about," Barry said, while used, sometimes the group tended to rely on their own pipeline and the DEO, especially since the DEO had expanded properly to include taking down metas. The CCPD jail tended to be the least thought of out of the holding facilities.

Everyone looked at Caitlin who just nodded. "Okay," she said.

"And I think you guys better hurry," Winn added, having kept a look on the computer as the main Superflash team talked. "She's on the move."

Kara and Barry nodded getting in their outfit now. "Krypto," Kara said to the dog. "Stay with Caitlin. Guard." Krypto barked his understanding and sat near Caitlin.

-Superflash-

After Lucy's revelation about knowing, the trio sat around Lois and Clark's kitchen table, not so sure what to say to each other. They could hear the kids giggling in the next room about something though. Most likely the thought of their own puppy. "I'm not going to ask why you didn't tell me," Lucy said softly. "I get it."

"You do?" Lois asked, looking at her sister having not expected that. "I've lied to you for years and you're not angry?"

"It's not like I was the type of person who you could tell this to. With my feeling towards the superheroes," Lucy said. "I know why you cut me and dad out. We didn't fit into your life, into your family. But maybe now I do."

There was a bing and Clark looked at his phone. He made sure to have his phone set so any news reports of on going crimes were sent to it. "An alarm at a bank just went off," Clark said getting up.

"Be back soon," Lois could barely say as Clark rushed into his outfit and was out the window s moment later. "He'll have this done with soon."

"How do you handle that?" Lucy asked, amazed. "I mean, I guess I am sort of in the same boat now with Ray and I am starting to wonder if I can take it. I mean, especially now his on this secret mission thing, whatever the hell he is doing, and can't contact me."

"He's time traveling," Lois said having been caught up on that by Sara who told the entire superfamily about Rip. Ray hadn't even told Lucy what he was doing, so this caused Lucy to give Lois a weird look. "A guy from the future asked him and a couple others for help with this immortal bad guy, Savage-something, and I know how weird this sounds, but it's my life. I am use to it and if you want to be with Ray and a part of this superfamily you'll have to get use to it too. This life brings wonder and dangers and– ELLA!" Lois yelled, realizing smoke was coming from the kid's bedroom. "How many times do I have to say not to use your heat vision in the apartment!" Lois grabbed a fire extinguisher, going into the room with it.

"So the kids do have powers," Lucy said, trying not to laugh as she heard Lois put out the fire and take the kids out of the room, putting them back in front of the TV with a little force.

-Superflash-

Oliver looked at the new woman. "You want me to train you?" Oliver finally asked. "Why?"

"You're the best," Artemis said simply. "The best vigilante there is and anyone who has been with you is also the best. The only one who comes close to you are that Nightwing and his sidekick Arsenal in Bludhaven, but you… you play with the big dogs. The people with powers who shouldn't need you at all to help them but they not only need you, they value you. If I want to be the best I need to be trained by the best."

"Look Arte… what's your name? Your real name since I am sure it's not Artemis," Oliver said.

"Paula Bertinelli," she said with a sly smirk.

"Any relationship to Helena Bertinelli?" Oliver asked, suddenly curious and careful.

"She was my sister," Paula said.

"Was?" Thea chimed in.

"She's dead now," Paula said. "Killed by a couple of cowards and one day they will get what's coming to them." Paula moved her bow and Oliver knew what she meant.

"I am sorry about your sister." He had known Helena a little too personally upon his return to Starling and knowing she was dead… well, it seemed her arrogance had taken her life, as well as rubbed off on her sister. "There are two ways revenge can go. Either you live your whole life trying to get it and never do or you dedicated your life to and after you get it you have no life. Don't let it control you. Let it go," Oliver said simply. "Go home and get away from all this."

"I'm going to be a vigilante either way. I have a lot better chance of surviving if you train me," Paula said, Oliver beginning to see Helena 'Huntress' Bertinelli's attitude reflected in the woman before him.

"Do what you want, but I don't need you," Oliver indicated to Thea that it was time to go, his sister looking between the two with intrigue.

"Actually Olly, we could use her," Thea said, causing Oliver to turn around and look at his only crime fighting partner.

-Superflash-

Kara and Barry flew out to find Crystal on top of a building. "Crystal!" Kara said, wondering if they could talk this out instead of fighting. "You don't want to do this. Not really. You don't want to hurt Caitlin."

"You two work with my sister?" Crystal said. "She is nothing! Nothing compared to me. I have the powers. What does she have?"

"There is more needed than just powers to do this," Kara said, Barry standing on the roof now, waiting to see if his wife could talk her down.

"Well… you're going to need powers now," Crystal said, ice appearing around her hand. The two prepared for battle but was shocked when Crystal pointed upward, the ice hitting a plane that had taken off from the nearby airport and the plane clearly, instantly, lost control.

Kara didn't wait a moment before flying upward and going to catch the plane before it crashed, leaving Barry alone with Killer Frost. Barry went to run at her but ice blocked him. Then the whole roof was iced over. Barry realized how bad this meta was for him, considering the damage the cold could do to him. Barry went to dodge an ice ball that was thrown at him but he slipped on the ice on the floor and the ice hit his side.

Killer Frost had ice in her hand and started shooting it at Barry.

…

In the lab Caitlin, Cisco, and Winn were panicking, not sure what to do. "He's vitals are going insane!" Caitlin said.

"Kara, Barry needs you," Winn said to Kara.

"Catching a plane is not so easy," Kara said, worry clearly in her voice.

"Barry, take out your ear piece. I need a word with my sister," Caitlin said.

…

Barry managed to get his earpiece out and held it up to Crystal. "Crys!" Caitlin voice was audible through the piece as she shouted her sister's nickname. "Put the earpiece in. Let's talk."

Crystal laughed as she took the earpiece. "You think this will stop me from killing your friend here?" Crystal said. "Oh, Little Ms. Perfect has to try though."

"You think I'm perfect? That my life is perfect. Well, you're wrong. I'm as flawed as any human being… I spent years working for a mad man without knowing it. A man who used us to cause so much damage and knowing what would happen. You don't think that eats at us? At me? That we were used. Even helping take him out doesn't take away the pain that we caused. And my husband? My husband is one half of a superhero and can't be away from his other half for long. We can't even go on long breaks away. He also ran off with a time-traveler to who knows where and hasn't returned. I don't even know if he will. I mean, what if they all die in the future? How am I ever going to find out? My life is far from perfect. I put myself in dangerous situation every day to help these two superheroes you're with, but I love it. I love my life and I love them. I found something and you can too if you let go of the past."

"Oh how nice," Crystal said. "You found something by abandoning your family. By abandoning me."

"How could I abandon you? Do you not remember our childhood? We barely spoke when we lived in the same house. We're family in blood and looks only, and there's more to family than blood. I learned that now because I have a superfamily I love and would do anything for, including the man you want to kill right now… so take me instead." Caitlin said suddenly. "You can kill me for what ever twisted revenge you want, just leave him alone."

"You would die for him?" Crystal said, her voice softer than it had been before.

"In a heartbeat." Caitlin replied.

Crystal took the earpiece out and looked at Barry. She knocked him over the head with ice, knocking him out, and then left the roof.

-Superflash-

When Clark returned Lois and Lucy were sitting at the table talking and the kids were by the TV. "Clark, put the kids to bed would you?" Lois said, not even turning around. Clark shrugged and turned off the TV to get the two kids ready and to bed.

When he was done, he went back in to find Lois had set up their couch bed. "Lucy is staying the night," Lois said.

"So everything is good here?" Clark asked, looking at the two.

"Yes," Lois said, smiling at Lucy. "Everything is good here."

"I got a lot to learn about being with a superhero, but Lois is a good tutor," Lucy said with a smirk.

"Yeah. Lois has taken to taking the newbies of the superfamily under her wing," Clark said, causing Lois to laugh. "What is this? Three or four?"

"Three," Lois said. "First Barry before he was the Flash…"

"What? Barry is the Flash?" Lucy asked, making the two look at her like she was dumb. "I should have figured that out when I realized Kara was Supergirl." Lucy moaned, feeling dumb herself.

"Then Iris, and now Lucy," Lois finished. "I was technically the first so I guess it makes sense for me to help the others."

"Well I better let the others know your part of the superfamily now," Clark said, taking out his communicator to send a message to everyone.

"Oh, when you get back to Central City, you should totally ask Kara to show you the Superflash cave," Lois said suddenly. "They have a pretty good setup there."

"Do you guys put 'super' in front of everything?" Lucy asked, amused, as Clark put his communicator away. "I mean Superman, Supergirl, Superdog, superfamily, Superflash cave… Is there anything else? How long until Barry's rebranded 'Superspeed'?"

The two laughed at this, having not noticed before but realizing it was a little insane, especially for someone on the outside of all of this.

The adults spent a couple more hours talking before heading to bed. As Lucy lay down on the couch bed she couldn't help but smile. She had her sister back and she had a feeling now she had a very weird family as well. She liked it especially, since she no longer talked to her father and her mother was long gone. She wondered what the future held.

-Superflash-

"What do you mean we could use her?" Oliver asked. "We just can't let anyone and everyone on the team."

"What team?" Thea asked. "Look around Olly." Thea held up her hands and turned around. "There's no one here. Diggle moved with Lyla when she got reassigned to Kansas. Sara moved to National City for love. Ray basically did the same thing and he went off with that Rip Hunter guy. Laurel too. The team is me and you on the field and Felicity on computer these days. We don't have a good track record at the moment for keeping team members."

"Thanks for including me," the two heard Felicity's cheerful tones through their coms.

"We could use some extra help. Especially considering the two major threats we have," Thea pointed out.

"I agree with Thea," Felicity added.

Oliver groaned as the girls ganged up on him. He had to admit that they were right though. The team was very short-handed. "I won't be easy on you," Oliver turned back to the woman as Paula smiled, knowing she was getting her way. "And as Thea said, we have two major threats looming. Darhk around these and then the Justice League has an unknown threat facing us, ready to spring into action at any time."

"I can help," Paula said.

"I can't guarantee you'll survive either," Oliver said, a little darkly.

"Isn't that the risk we all take?" Paula asked. "Could get hit by a bus in the morning and not survive…"

"Fine, but your riding on the back of Thea's bike," Oliver said, moving over to his own bike without another word and leaving.

Thea got on hers and waited for Paula to get on the back. "Where did you get such a cool bike?" Paula asked, impressed by what she saw.

"We have friends," Thea said as she started the bike and left.

-Superflash-

Barry woke up in STAR labs and looked around. Kara was near him and Caitlin, Winn, and Cisco not far off. "What happened?" Barry asked.

"Well I saved the plane and then went back. You were unconscious on the floor so I brought you back here," Kara said putting her arms around her husband. "That was several hours ago."

"What about Crystal?" Barry asked and some of the group shrugged.

"She disappeared," Winn sighed. "I tried tracking her the same way you did but it's not working."

"She must know how to control her powers well enough to hide herself," Cisco added.

"If there was someone who could figure that out it would be her," Caitlin said. "Crystal was smart when she puts her mind to it."

"She could still be out to get you," Barry said warningly.

"It's a very real possibility," Caitlin said, nodding, "But I have a feeling she's gone for the moment."

"Either way you're coming home with us for the night," Kara said and Caitlin knew not to argue with her friend. "Barry you good to run back home?" Barry nodded. Kara picked up Caitlin and the three left.

…

When Caitlin was settled in the guest room, Krypto curled at the bottom of the bed protectively, Kara and Barry went into their own room. Barry had just taken his clothes off and laid on the bed in his boxers. "I got a voicemail from Lois," Kara said, looking at her cell. "If it's her telling us Ray spilled the secret to Lucy she should have known Clark already sent a message."

What?! Barry thought, surprised.

Check your communicator, Kara thought back.

Too stiff. In the morning. What did Lois say?

It's actually Jason. Must have taken his mom's cell, Kara thought back, a smile on her lips as she listened to her nephew's voice.

What did Jason say? Barry asked a smile on his as well.

I'm not a hundred percent sure. Kara thought back. He tried to do it in Kryptonese but I think he got something wrong. He's going on about Krypto and puppies. I'll ask Lois in the morning.

Kara put the cell down and lay next to her husband. Barry put an arm around his wife. You ever think about having kids? Kara asked him as she put her head on his chest.

With you all the time, Barry answered, sharing with Kara some of his fantasy on how their kids would look. But right now we have to concentration on the league and this Brainiac 8 person.

Yeah… no room for kids at the moment. Maybe someday, Kara thought back as the two settled down for sleep.

Post chapter Note 1: Yes, Artemis was the winner of the vote. It was actually a landslide in Artemis' favor and I hope you like the version I used. If you're curious the finales tally was:

First Place- Artemis, with 16 votes

Second Place- Pantha, with 4 votes

Third Place- Lady Shiva, with 3 votes

Fourth Place- Green Hornet, with 2 votes

Last Place- a tie with Vigilante and The Shadow, both getting 1 vote.

Post Chapter Note 2: I am sure most of you expected me to use the Artemis that will be in season five of Arrow. Truthfully I was thinking that originally too, but after some research (and not really knowing how Artemis will be in season 5) I found I liked this version better. Artemis is usually related to the Huntress (for example in Young Justice she was the Huntress' daughter) so I made them sisters (which fit really well with the other two plots in this chapter) and hey presto, it worked! So now that I have an Artemis of my own, the season five Arrow Artemis doesn't exist here.

So, please remember to REVIEW.

Next Time on Karry Universe:

The Brainiac Battle- the battle between the Justice League and Brainiac 8 and her Kryptonian army is here. Everyone has their part to play but in a battle this big will everyone come out alive? At least one character may not, so be warned now…

Karry Master OUT!
