Karry Universe

Disclaimer: Only the idea is mine. The characters and locations belong to DC comics.

Note: Okay now that Kara is Supergirl I think I have to make one thing clear. I WILL NOT be rewriting every episode of the Flash and Supergirl. This is an original story and while my plans are heavily based on the events that happened in Supergirl and Flash season one I will not be redoing every episode. Either one of three things will happen with the episodes we know:-

1: There is a rewrite in the story; There are a couple of episodes that are worthy of a rewrite with my own twists. I won't say which ones though.

2: The events are important enough to be mentioned, but not rewritten. In this case the events happened ALMOST exactly the same way it did in the TV show. I say 'almost' because this is a different universe and things are obviously different. For example, Winn does not know Kara is Supergirl so anything he did to help because he knew would have to be changed.

3: The events will not be mentioned at all. In this case the event either didn't happen or did happen but are not important enough to this story to be mentioned.

H2-No.

"Who's the hot girl with the coma patient?" Cisco asked coming into the lab where Caitlin was sitting looking at a computer.

"Oh right. Kara usually comes on your day off," Caitlin said. "That's his girlfriend, Kara and his name is Barry by the way." Since they met a couple of weeks ago Kara and Caitlin had been getting closer. When Kara came to visit, Caitlin sometimes sat with her near Barry. They talked. They even went out to grab lunch together a couple of times.

"Oh your new BFF," Cisco said having heard about Kara from Caitlin. Caitlin gave Cisco a look. "What? I think it's great you got a new friend. Even if the two of you are bonding over one dead fiancée and one comatose boyfriend." Cisco noticed the look Caitlin was giving her. "I should shut my mouth."

"Yes," Caitlin said knowing her friend and co-worker sometimes said too much.

"But seriously, how does that guy get a hot chick like that?" Cisco said.

"Maybe because he doesn't call me a 'hot chick'," Cisco heard a voice and turned around to see Kara was standing in the doorway between the lab they were in and the room Barry was located. Caitlin laughed at the look on Cisco's face.

"It's a compliment," Cisco said trying to defend himself. "For both you and Barry."

"I don't know. Sounds more like an insult to my boyfriend," Kara said. "Caitlin I think we have to show this one a lesson."

"Yeah I think we do," Caitlin said and Cisco looked worriedly back and forth between the two stony faces until they both cracked and laughed. "Should have seen the look on your face!"

"Thank you, I've been needing to laugh for a while," Kara said. The weeks since Barry had been put into a coma hadn't been laughing weeks. They have been very serious and brought down by the fact that there was no emotions from Barry over their bond. Feeling nothing from him just made Kara even worse, but she had her duties at CatCo and as Supergirl to keep her going. Every time she saved someone or took down a criminal or alien fugitive she felt like she was honoring Barry. She knew if Barry was awake he would be cheering for her on from the sidelines. "Kara Danvers." Kara held out her hand to Cisco who took it.

"Cisco Ramone and that wasn't funny," Cisco complained but saw the look in Kara and Caitlin's eyes. If they needed to laugh he would find ways to make them laugh.

"Nice to meet you, and for your information Barry is a great guy. Nice, sweet, funny, and we have a lot in common. He is also very good looking if you hadn't noticed," Kara said.

Cisco held up his hands in surrender. "Okay, okay, I'm sorry. He's obviously a great guy to have a girl like you coming to sit by him while in a coma. Can't wait until I can actually meet him," Cisco said figuring that was the best way to get out of this situation. "So Kara what…?" Cisco stopped when he noticed Kara was looking passed him and not listening.

He turned around to see their TV was on and on mute but the news was showing something attacking the city. "What is that?" Cisco asked unmuting the TV.

"A guy made out of water seems to be attacking Central City. So far all attempts to stop him have failed…." The newscaster's voice was saying.

"Where did Kara go?" Caitlin asked. Her attention had been on the TV until she had turned around to look at the other two to say something and noticed Kara was missing. Cisco turned around to see Kara gone too and checked Barry's room but she wasn't there. He shrugged.

-Superflash-

Kara had run out while Cisco and Caitlin were occupied by the TV and gotten into her Supergirl outfit. She flew fast to where the man made of liquid was attacking and grabbed an innocent from his watery grip before he could react. The girl she had saved was coughing up water too. "Take her and run," Kara said to a man near her who took hold of the girl and ran.

Kara turned around to face the water man… thing. It seemed to be entirely moving water until it joined together and Kara could swear she saw a human face and body with water flowing from every joint. "What are you? Superman's little sister," the water guy said, his voice positively gushing with fluid. It sounded the same way one would sound when you tried talking with your mouth full.

"Cousin," Kara said confused. It had been weeks since she had revealed herself to the world and everyone knew she was Superman's cousin by now. "What planet are you from?" Kara automatically assumed this was an alien; after all she had fought enough Fort Rozz escapees with the DEO since she revealed herself.

She had been sort-of forced into a partnership with the DEO. She didn't really want to work with a government agency, especially after talking with Clark about why he didn't, but with the threat of her Aunt Astra and her husband, Non, somewhere out there Kara had no choice. Besides the DEO was better able to hold the aliens she defeated than anywhere else since, especially Kara did not like the thought of killing them. It also helped that her sister worked for the DEO.

"This planet," water-man said throwing his arms down and caused a small flood to rush at Kara. "They did this to me!"

"Who?" Kara asked.

"They will pay. Everyone will pay," the water-man said suddenly, a jet of water thrown at Kara now. Kara almost lost her balance from the force of the jet but managed to catch herself and hold her ground. She powered up her eyes and shot out her heat vision. The blast seemed to go through the water and the water-man's arms evaporated for a moment before reforming.

"Okay heat vision does not work," Kara mumbled to herself. "Let's see how you like this." Kara took a deep breath and let out her freeze breath, hoping to freeze him solid.

It seemed to work as the water-man quickly iced over and Kara thought she'd easily won until she saw the arm now made of ice move. "I like this," the guy said, his voice more solid too, throwing a punch at a nearby wall and causing the bricks to implode. The now-ice-man turned and ran through the streets away from Supergirl causing as much damage as he could.

"You got to be kidding me…" Kara groaned, flying after the running ice-man. Getting him in her view she used her heat vision to melt him. At least as water he couldn't do as much damage to the city as he could as ice.

The man screamed as he was melted but didn't stop to fight Supergirl once again. Instead he continued heading in the same direction he'd been going. "They will pay. They will all pay for what they did," Kara could hear the man mumbling with her super hearing.

"Where's he heading for?" Kara asked herself looking around. With the direction he was going the only thing he could be going for was – "STAR labs!" Kara suddenly said and then picked up her speed. This water-man was not only threatening her new friends but Barry too and she would not let Barry get hurt again.

-Superflash-

Cisco and Caitlin had been glued to the TV as it showed video of Supergirl appearing to save the day. Since she had first appeared on her own it was clear to all Supergirl was not her cousin's sidekick. Her cousin might have trained her but she was her own superhero. In fact the only places she had been seen recently were Central and National City leading everyone to believe the sister cities now shared a hero.

"Got to give her credit for the idea," Cisco said as they saw the freeze breath plan fail and the cameras lost sight of both the ice-man and Supergirl.

"Yeah," Caitlin said looking around. She had expected Kara to show up again but was getting worried when she didn't. "Maybe I'll go see if Kara went to the bathroom or something."

"Oh I'm sure she's fine," Cisco said.

"Still," Caitlin said getting up from her chair and heading for the door. She never got there though as water appeared on the ground in front of her and she was suddenly face-to-face with the water-man from the news.

"You did this to me! You pay," the water guy garbled, an arm going at Caitlin and Caitlin was suddenly drowning on water. Cisco went to grab her but the other arm shot at him and he was choking down water too.

Then there was a blur running straight through the water-man, grabbing both of them, moving them back. Supergirl had saved them. The two were coughing up water on the floor looking at the now-wet superhero. "Get out of here," Supergirl said and started throwing heat vision at the water guy. It didn't work though as every time the water evaporated more seemed to appear to take its place on the water body. She tried throwing punches but her fists went right through the liquid body.

"What are you doing Cisco? You're going to get yourself electrocuted!" Caitlin said, seeing Cisco was tearing apart a console and going for the wires inside.

"No I'm going to get him electrocuted," Cisco whispered looking at the battle going on. Supergirl couldn't do any damage but her speed seemed to be keeping the water-man at bay.

Caitlin realized the plan and smiled. "Hold on," Caitlin said running over to the controls and shutting the power down to the console Cisco was working at to make it safe for him to grab the wires needed.

Cisco grabbed the largest electric wire he could find. "Supergirl," Cisco yelled and threw the wire to the superhero. She caught it, seeming confused for a second and then Caitlin turned the power back on full force.

Electricity came from the wire and Supergirl smiled putting it into the water-man. The water-man screamed as the electricity hit him. Cisco and Caitlin were safely out of the pool of water and Supergirl was able to take on the power without damage. Then the water man fell to the ground unconscious and surprisingly whole for a body made of water. "You okay?" Caitlin asked, turning off the power to the wires Supergirl was holding. Supergirl nodded, looking slightly worse for wear but okay overall.

"Takes more than a little electricity to take me down," Supergirl said, looking down at the water-man. Now unconscious his body seemed more solid but there was still water coming from him. "You have a cellphone I can borrow?"

Caitlin nodded, taking her cellphone out of her pocket and handing it to Supergirl who dialed a number. "Agent Danvers," Supergirl heard her sister answer.

"Agent, it's Supergirl," Supergirl said. "I have… I don't know a guy made of water unconscious at STAR labs. Can you come get him?"

"Already on our way to Central with a water tight container for him. We'll be at STAR labs soon. Good work Supergirl," Alex said and the phone call was disconnected.

Supergirl deleted the number from Caitlin's recent calls list and handed the phone back to its owner. "He looks familiar," Caitlin said looking down at the unconscious water guy. A human face was clearly visible now.

"You think Water Guy looks familiar?" Cisco asked dubiously as Caitlin went to the computers. "Water Guy. Not a good name. Water Menace? Water Flow? Oh! H2-Whoa. No, actually H2-No. Get it? No instead of Oh. 'No' is simpler you…" Cisco looked at Supergirl who was giving him a look.

"Are you seriously trying to name him?" Supergirl asked.

"Well every super villain deserves a good name just like every super hero," Cisco reasoned. "Which, by the way, what's with the 'Supergirl' mantra?"

"I didn't make it," Supergirl said. "But I've grown to like it."

"But you're not a girl. You're a woman," Cisco said, "Superwoman would have been…" he let his voice drop at the look Caitlin was now giving him and Supergirl had to bite her lip from commenting. She had said something similar to Cat Grant after she had returned from vacation, but had been viciously turned down on the suggestion.

"Well take that up with Cat Grant if you have the guts," Supergirl finally said. It wasn't much longer before Alex walked in with a few other agents and a coffin-like containment system. "Do I want to know why you have a water tight container for prisoners?" she asked her sister.

"Be prepared for anything," Alex said as they got H2-No into the container, "We'll take him back to headquarters and see if we could figure out what he is."

"Found him," Caitlin suddenly said surprising everyone. "I knew he looked familiar. He's Cole Denyer." The group of agents, Supergirl, and Cisco looked at each other and then back at Caitlin.

"Cole Denyer?" Alex asked.

"He's the star of the Central City High School swim team. He was in training for the Olympics but he disappeared…" Caitlin said and then a look came across her face. "…the night the particle accelerated exploded. He was considered missing, presumed dead."

"'The ones who did this will pay'," Supergirl quoted. "That's what he was saying."

"The particle accelerator did this to him?" Alex said looking at the guy who had finally woken up and was trying to escape his containment but failing.

Cisco and Caitlin looked at each other and then shrugged. "Maybe," Caitlin admitted.

Alex rolled her eyes. "Well we'll see what we can do with him," Alex said and ordered the other agents to take him away. That was when Alex noticed the door to the next room. From where she was standing you could barely see Barry in the room. She headed for it.

"Agent you can't…" Caitlin said but stopped when Alex stopped at the door. She saw the looks on Alex's face. "Do you know him?"

Alex was tempted to say 'yes' but she didn't want anyone to know she was related to Kara as yet. The connection to Supergirl could become too obvious, not to mention the DEO. "No," Alex said but Caitlin could tell she was lying, "just feel bad for anyone in a coma. I better go. Good work Supergirl." Alex repeated the line and then left.

"Well, I have to go too," Supergirl said now that H2-No was gone. "Thank you both for the help." Before either could say anything Supergirl had sped out of the labs.

"There was something weird there," Caitlin said but before Cisco could answer Kara walked back into the lab.

"What happened here? " Kara asked referring to the mess and the water.

"Where were you?" Cisco asked.

"Went to get something to eat," Kara said quickly.

Caitlin and Cisco looked at each other as Kara walked passed them back into Barry's room. The two could hear her singing to Barry. Kara spent a few more hours there before she had to leave. Apparently she was going to meet Joe and Iris to have dinner.

When she was gone Cisco turned to Caitlin. "You realize your new BFF is Supergirl right?" Cisco asked.

"Yeah," Caitlin said. "It's super obvious after today."

"How did you not realize this before? I mean she wears glasses and puts her hair up," Cisco said. "No mask or anything."

"Before Kara disappeared and Supergirl appeared to fight Cole…"

"H2-No," Cisco said.

"We're not calling him that," Caitlin snapped, continuing: "And then Supergirl left and Kara reappeared, did you think they were the same people?" Cisco had to agree with Caitlin there. "It seems to work. What she's doing." Caitlin put her hand on her head. "When we first met she said when Barry got hit by lightning something broke in her and she ran to her cousin. I assumed she spent a week crying but really…."

"Superman was training her," Cisco said.

"Which means she became Supergirl because of Barry ending up in a coma which means…"

"We created Supergirl," Cisco said, shock in his voice at the revelation.

"In a weird backwards way yes," Caitlin said.

"Should we tell her we know?" Cisco asked.

"No, it's her secret. Let's just keep it to ourselves," Caitlin said getting up. "I got to go take care of Barry."

"Do you think he knows?" Cisco asked.

Caitlin thought for a moment of all her encounters with Kara and then nodded. "Yeah I think he knows. She loves him too much for him not to know she's an alien," Caitlin said.

"Dating a hot alien. Very Star Trek of him. I think I will like this guy when he wakes up," Cisco said. "I wonder if she has a hot alien sister in hiding somewhere for me." Caitlin gave him a look but went into Barry's room without reply.

AN: Hope you enjoyed the first appearance of a meta-human and Cisco. REVIEW.
