Karry Universe

Disclaimer: I do not own any characters, but the idea is mine. ;-)

PLEASE READ THE FOLLOWING NOTES

Note 1: I do have plans for Oliver and some of the Starling (Star) City group, but I want everyone to know I DO NOT WATCH ARROW. My knowledge of Arrow comes from the crossovers with Flash and Legends of Tomorrow. Also my Beta Terrance Sigma watches Arrow so he's heavily involved with keeping the character and timelines right.

Note 2: Okay there is a very large time jump between the end of last chapter and this chapter. Just a warning here but people have been wanting this, so the Karry Master obeys.

Note 3: As mentioned above, this is definitely the chapter everyone has been waiting for. So without anything further ado…. DRUM ROLL AGAIN PLEASE!

The Making of a Hero

Barry sat in his lab looking around in exhaustion. After he had finally gotten back from Starling, having met the infamous Oliver Queen and befriended the geeky Felicity Smoak too, intending to run a lead for his mother's death but coming back blank, except for his run-in with one of Starling's current hero Vigilante, the Arrow – who was actually Oliver himself, it was complicated – he had come back to Central City to find his beautiful girlfriend waiting for him.

They had both gotten vacation time from their jobs. They were going to watch STAR Labs turn on their Particle Accelerator and then they were going on vacation together.

After over a year of living apart both of them knew they couldn't take it anymore. They wanted to be together. The only problem was that they had a disagreement on who should move. Kara wanted Barry to move to National City while Barry wanted Kara to move to Central. It had ended in a big fight and Barry retreated to his lab to think and rest.

Now he was regretting leaving Kara there angry. He could feel her annoyance through their bond and undoubtedly she could feel his guilt and frustration in return. He went into his pocket and took out a small jewelry box. He opened it up to look upon the diamond ring inside. While in Starling he had asked Felicity and Sara Lance to help him get the perfect ring for Kara. He was planning to propose during their vacation.

Barry put the ring away and closed his eyes. He felt Kara's emotions and sent out positive vibes to her, not wanting either to be angry for long. He was glad when Kara sent back positive emotions as well. It was better than saying I'm sorry for the two of them. They still needed to discuss living arrangements, but they were good with each other now. Simple as that. Barry was going to go find her, but that was when he heard an explosion.

Opening his eyes in shock, Barry directed his sight to the window where he had the perfect view of STAR Labs in the distance. He'd known he was going to miss the switching on of the accelerator the moment he had stormed away from Kara and part of that was the reason he'd felt so angry to start with, but now he was glad – something had gone wrong.

Moving over to his television to turn it on and see what the news coverage was saying, he didn't make it that far when his peripheral vision was alerted to something unusual. Turning, he noticed the liquid contents to his random experiments were… they were levitating! That wasn't good.

Before he could do any more, there was another explosion of sound, he saw a second of falling, shattered glass and a bright light, there was pain and then… nothing else.

-Superflash-

Kara smiled at the positive emotions she felt from Barry. It had been such a stupid fight. She loved being Ms. Grant assistant but she had decided she'd give it up in a moment for him. She could seek other opportunities; maybe ask Iris what media positions were open in Central. She was going to go find him when she heard the explosion. She looked towards STAR labs, using her superior sight to see as far as she could. She could tell something had gone wrong – something had happened at the Labs.

Not a moment later she felt a pain in her heart. A pain from Barry and then emptiness. She almost saw the lightning hit him in her sub-concision. Everyone around her was so panicked by the sudden disaster, even the electricity blacking out, that they didn't see her speed off faster than anyone should be able to. "Barry!" Kara yelled, running into his lab to find him on the floor. His lab looks like it had been trashed and he was surrounded by shattered glass from the broken skylight above him. "Barry..." Kara ran over to him. She could hear a heartbeat, using her x-ray vision to see his heart, but it was faintly beating.

"No, no," Kara said tears brimming in her eyes as she picked him up. She flew as fast as she could to the hospital and ran inside barely caring about her secret. Only remembering to make it look like she was struggling to carry Barry at last moment. "He needs a doctor!" Kara yelled and a gurney seemed to appear out of nowhere, she put him on it as a few nurses seemed to appear to grab the thing.

"Barry…" Kara said trying to stay with him but being pulled back. She didn't realize that soon the hospital would be overflowing from the Particle Accelerator incident.

"Let them do their job," a nurse said as Barry was wheeled away from her, and Kara nodded knowing she had to. "Are you family?" Kara shook her head. "Relationship to him?"

"Girlfriend," Kara said.

"What happened?" The nurse asked.

"He was struck by lightning," Kara said, causing the nurse to do a double-take but didn't give her a chance to ask more as she gave the nurse Barry's name and any other information she had. "You've got to save him."

"We'll try. Go call his family," the nurse said and Kara knew she had to.

After the call with Iris, Kara barely took in anything more. She didn't react when Iris and Joe came running into the hospital. She barely saw the craziness around her – the explosion had caused a lot of injuries, the hospital soon overflowing, but Kara didn't notice anything. Her super hearing, though, seemed out of control. She heard voices announcing people dead. She heard people talking about injuries. She heard people mention strange mutations.

"Family of Barry Allen?" a doctor finally called and Joe stood up. Kara looked up too, almost not seeing the doctor though.

"I'm his father," Joe said. "Is he alright?"

"We managed to stabilized him, but…" the doctor looked at the group. "I've never seen anything like this before. It's too unknown what's going on since the explosion at STAR Labs… We do know Mr. Allen is in a coma and I can't make any promises. I would prepare yourselves for the worse as he may never wake up."

"Can we see him?" Iris asked, her voice hollow as her eyes glistened with tears. The doctor nodded and showed the group to a room where Barry was on a bed. Iris and Joe went right to his side, but Kara stood at the door looking at him. She felt completely numb. All her super powers seemed to have died as the doctor spoke – she could barely hear what was being said around her now, let alone elsewhere in the hospital.

As she looked at him it was like she was seeing more than just him, though. She was seeing her parents. Hearing them telling her to protect her cousin. Seeing her planet destroyed. Seeing her cousin for the first time when she landed. Knowing she failed. Failed protecting him. Seeing Barry lying there. She had failed him too.

As the realization hit her, the numbness in her body seemed to lift. Voices exploded all around her. She could hear everyone in the hospital suffering. The hospital staff panicking. She had failed everyone. Everyone she could have protected. Her eyes couldn't leave Barry though. The man she loved more than anything was in a coma, possibly dying because she did not save him.

"Kara," Iris said finally noticing that Kara remained frozen on the spot. She had never seen such a look on her friend's face. She looked so small, too. Like she was broken. Kara finally looked at Iris, her eyes heavy, and then turned, running out of the room. "Kara?"

"Iris," Joe said putting a hand on his daughter's shoulder, his voice quaking. "I think Kara is having bad flashbacks. She needs someone closer to her than us, but she'll be back. She loves Barry and until she does we're here for him." Tears were running down his face too, but he had to be strong for his daughter, and for Barry, as he pulled Iris into a hug.

-Superflash-

"Both kids are asleep. Nothing is on fire and no beds broke. I think we need a bigger apartment though," Clark said walking out of the bedroom seeing his wife glued to the TV. "How is everything?"

"Central is a mess," Lois said. "The particle accelerator explosion is causing a lot of death. They haven't been able to count them all yet."

"Maybe I should fly out there to see…" Before Clark could finish his sentence there was a gust of wind, a blur, and a force hit into him so hard he nearly fell back. Lois jumped. Clark was almost ready to fight before he heard the crying and realized who was hugging him. "Kara!" Clark was shocked and looked to Lois. It took a moment before he put his arms around his weeping cousin and then picked her up.

He sat down on the couch and held her on his lap, letting her cry. "What's wrong?" Clark asked.

"Barry – lightning – coma," was all Clark and Lois could make out through Kara's tears. It was enough to make the two understand though what had happened. Clark held his cousin tighter and Lois came over to rub her back. They stayed that way until Kara had cried herself to sleep.

"Get up," Lois whispered and Clark stood up and watched as Lois set up the couch-bed. When she was done Clark gently put Kara onto the bed and then followed Lois into their bedroom where she was looking around in the closet for blankets and pillows. Tears were forming in Lois's eyes now.

"Lois, come here," Clark said bringing Lois in a hug and letting his wife cry. Ever since Kara had revealed her Kryptonian self to Barry he and Lois had gotten closer – both sharing something no one else could. The ability to love an alien. "Barry will be fine. If I have to go to the Fortress and figure out some Kryptonian way to wake him up I will. I'm not letting him die."

"We've got to be strong. For Kara," Lois said quietly.

"You loved him too. Not in the same way as Kara but you did love him. It's okay to be upset," Clark said. "I'll be strong for both of you."

The two heard moaning coming from the living room and knew Kara must have been having a nightmare. "No, you'll be there for her. She's the one who needs you." Lois handed some blankets and pillows to Clark. "Go in there and hold her through the night. I'll be fine."

Clark gave Lois a look but nodded and went back into the living room. He put the pillows down and the blanket over Kara. He then lay down next to her and brought her into a hug. "I'm here for you," Clark whispered.

-Superflash-

"Mommy," Jason was poking at Lois the next morning. Lois woke up to see the three year old on top of her. "Auntie Kar-wah's here."

"I know baby," Lois said sitting up, not sure how to tell Jason his aunt wasn't here for him though. Kara made trips out to Metropolis to see her niece and nephew all the time. Clark even brought them out to National. "But Auntie Kara is very upset. Something very bad has happened. So I want you to stay in yours and your sister's room for a bit until me and daddy can talk to her. Okay?"

The little boy seemed confused but nodded and Lois led him back into the room where he sat on the floor to play with his Superman toy. She checked on Ella, but the one year old was still asleep in her crib.

Lois went out into the living room to find Clark up and Kara seeming to stir. In a matter of minutes Kara was up and looking at the two of them. She tilted her head down in sadness. "I was hoping it was a dream," Kara mumbled as Clark wiped tears from her eyes.

"Tell us everything," Clark said.

Kara stood up and looked out the window as she talked. Telling them about the fight and about everything that had happened. "When he was struck by lightning it was like I felt it myself," Kara said. "And when I was looking at him laying there in the hospital it was like I was losing everything, everyone, all over again. My planet, my parents, my home… my Barry."

"You haven't lost him yet. He's still alive," Lois said.

"But I failed. I failed again," Kara said.

"Failed what?" Clark asked.

"Protecting! I was sent here to protect you. I failed. I should have protected him, the best thing that ever happened to me, but I failed again. In that hospital. All the panic I saw. All the voices. Everyone who died or was injured. Fail, fail, FAIL! I could have protected them. I could have protected him. I didn't. Why? Because I wanted to live a normal life? I'm never going to have a normal life. Not completely. I know that. That's not the reason I didn't save them."

Kara turned to look at Clark. "It's because of you," Kara said and Clark looked confused and slightly hurt. "Well not you really. Jeremiah, Eliza, Alex. When I was dropped off here. When you gave me to them, afterward I saved a women and a little girl from a car crash. Alex got hurt because she ran after me. After that Jeremiah told me the world didn't need me when it had you. They always tried to protect me by telling me not to use my powers. They told me to be normal and that just got stuck in my head. The world didn't need me. It had Superman. Even when I started using my powers more even after I saved your life and the people in that building the thought always came up. The world doesn't need me. It has Superman."

Kara sat down. "But you weren't there. The worst disaster and you weren't there. I was. I could have saved Barry. I could have saved a lot of people if I was just using my powers. If I was just like you and I can't do it anymore… You're right I need to save people. I need to do it for myself. I need to do it for Barry," Kara said and took Clark's hand. "Teach me how to be a hero, Clark."

"Are you sure?" Clark asked after a moment.

"Did you not just hear my speech? Yes I am sure," Kara said. There was a moment where no one spoke, the realization of what Kara had said, what Kara was agreeing to do falling on the other two. "Say something." Kara finally couldn't take the silence.

"I would, but I'm not sure that screaming 'Hallelujah!' so close to Barry being struck by lightning is appropriate," Clark said with an awkward smile and then brought Kara into a hug. "I've been waiting for this day. First thing you need is an outfit and I've been thinking of that for a while. Come on." Clark stood up and took Kara's hand bringing her into his and Lois's room.

Lois looked at the two and then shrugged. "And to think everyone believes the Particle Accelerator explosion is going to be the biggest news of the week," she muttered to herself bemusedly.

-Superflash-

Clark and Kara were flying over Metropolis. Clark was in his Superman outside and Kara in her new outfit the two had come up with; it was similar to his but more feminine. Kara had liked it, at least. They both had the symbol of the House of El proudly presented on the chest, nonetheless. "Car chase going down. Think you can handle it?" Clark asked.

"Yeah," Kara said, speeding ahead of Clark and seeing a large amount of police cars chasing a red Prius. There were also news helicopters all around.

Kara flew fast and got ahead of the red Prius. Landing in front of the car. She stopped it with her hand and causing a major dent to the hood. The four robbers in the car got out and pointed guns at her in panic. They fired but the bullets bounced off. Kara sped around them, disarming them fast and throwing them all down to the ground in front of the police.

The police cars had stopped and the police officers were standing their staring at Kara. All of them too shocked to move. The media helicopter had the cameras pointed directly at her. "I'd handcuff them, but I don't have any handcuffs," Kara said timidly to the police and a couple officers started to move to grab them.

"Not bad," Kara heard her cousin's voice and turned around to see Clark standing not far off. "But this was easy stuff. You still have a lot to learn, baby cousin."

"Lead the way," Kara said as she joined him. "And stop calling me baby cousin." Kara added as an afterthought as they flew off.

-Superflash-

Cat Grant's office was busy writing about the explosion in Central City; news kept coming through of strange symptoms from victims of the explosion and plenty of interviews with witnesses when the latest news caught her eyes on the screens behind her desk. The TVs in the office were immediately turned up high as people started noticing on the floor outside Cat's office, stared at the screen and watching the recap of the mysterious girl stopping the chase and taking down the criminals.

"…and police officers report hearing Superman call the girl his cousin. Seems we have a new hero in town," the new reporter was saying.

"Has the Daily Planet said anything yet," Cat asked turning to one of her employees whom was gathered near the door, she holding a tablet in her hand.

"Nope," the employee remarked.

"Good, then we have to label her before they do. Send out a message on all forms. Social media like Twitter, Facebook, over our own radio channel. Get Leslie on that one. Any media we have. Have it say…" she paused in thought before continuing: "'After the Central City explosion of yesterday CatCo welcomes the addition of new superhero: Supergirl'."

"Supergirl?" another employee asked.

"That's what we're calling her. It will catch on. Kiera!" Cat called.

'Um… Ms. Grant, she's on vacation," Winn pointed out timidly.

"Still?" Cat asked.

"Well you gave her a week off that started yesterday," Winn reminded Cat who moaned but nodded and went back to her desk. Assistants will have to wait, she had a superhero to make.

-Superflash-

Kara was sitting on the bed in Lois and Clark's apartment. Jason was next to her as she was talking on the phone. "How is he?" Kara asked Iris.

"Still asleep," Iris said. "We're transferring him to STAR Labs."

"STAR labs?" Kara asked, instantly defensive. After all, it was their explosion which had caused Barry's coma.

"Harrison Wells convinced dad they could save him, I have reservations but it's better than the hospital, I suppose" Iris said. "So you ran all the way to Metropolis?"

"I'm sorry," Kara said. "When I was standing there all I could think was I needed Clark. Jumped on the first plane available and…." Kara paused "It was a coward's move and I wouldn't blame you if you didn't want me to see him but…"

"Kara don't even say it. Of course you can see him. He loves you. You love him. Dad already put you on the list of people allowed to visit. Take the time you need and then come home." Iris said, ever the romantic.

"Thank you," Kara said.

"It must be exciting there with all that stuff about Supergirl," Iris said. "To think Superman has a cousin. I wonder where she's been this whole time."

"I don't know,' Kara said, smirking to herself.

"Is Lois going to be interviewing her?" Iris asked.

"Not a clue," Kara said. "I got to go." Kara saw Ella use her heat vision to set a chair on fire. "Bye!" Kara hung up and instantly used her freeze breath to put the fire out before Lois could get the fire extinguisher.

"Thank you," Lois said. "I got to get into work. Perry has been calling every few minutes. Clark is already there. Think you could babysit?"

"I'm fine," Kara said. "But one thing. What's with everyone calling me 'Supergirl'?"

"Cat Grant started it," Lois said. "Seems like it's going to stick. Sorry." Lois hugged Kara. "I know this is under the worst conditions but its nice having you here." Kara nodded as Lois left.

The rest of the week saw Clark training Kara on how to take on all types of criminals and situations. He had even shown her how to really fight – not the play fighting they normally did. Kara's vacation time was out though and she needed to fly back. It was a much different week off to what she had originally planned.

"Thank you Clark," Kara said, hugging her cousin and then Lois. Kara got on her knees and said goodbye to Jason in Kryptonese and Jason returned the goodbye. Kara had been teaching him the language for a while and the boy seemed to be a natural at picking it up. Kara hugged and kissed him and then Ella. "I'll be back when I can."

"If you ever need my help I'm one call away," Clark said knowing he was sending his cousin out to fight criminals on her own now.

Kara nodded and then flew out the window. She didn't go back to National though. She headed for Central.

-Superflash-

Caitlin Snow was the only one in the lab. It felt weird. Before the explosion, even at night the lab would be busy but now only her, Wells, and Cisco worked here. Everyone had left, the stigma of the explosion too much for their consciousness to bare. She was the only one here though and the only reason why she was here being because of the coma patient. Someone had to be in the lab at all times in case something went wrong with him and tonight was her turn.

"Excuse me," Caitlin heard a voice, which nearly caused her to jump. She turned to see a blonde girl with glasses by the door. "I'm sorry, and I know it's late, but I think my boyfriend is here? Barry Allen."

"Your Kara Danvers right? I saw your name on the list of people allowed to visit," Caitlin said.

"That would be me. I can show ID if you want?" Kara said taking out her ID and handing it over to Caitlin who looked at it before handing it back

"You're a little late. I can't let you in to see him right now. Come back tomorrow."

'I'm sorry doctor…?"

"Snow," Caitlin supplied.

"Snow, but when he was struck by lightning… something in me just broke. I ran to my cousin and hid there for a week, now I'm back, but I got to return to my job tomorrow in National, but I need to see him," Kara said. "I don't know if you could understand."

Caitlin looked in Kara's eyes and was shocked to see herself reflected in them. She'd had the same look in her eyes since Ronnie died that fateful day. She nodded. "My fiancée died during the explosion," Caitlin said sadly.

"I'm sorry," Kara responded, not sure what else to say to this.

"Which means I know what you're feeling," Caitlin added. "A few minutes won't hurt." Caitlin led Kara to the room Barry was in. "I'll give you a minute."

Caitlin left and Kara went to Barry's side and took his hand. She couldn't feel any emotions coming from him from the bond, but she knew the bond was still there. He was alive. "Barry, I don't know if you can hear me. I kind of doubt it since I am not getting any emotions from you, but just in case… just in case some part of you does hear me know that every life I save, everything I do as Supergirl," Kara was whispering his to him "it's all for you. It's in your honor. You come back to me. You hear? Come back…" Kara kissed Barry's head and she could almost swear she felt love coming from Barry's end of the bond. She had gotten so used to it though, maybe it was just a faint echo from the past.

Kara sat there for a while tears coming to her eyes, the first time she had seen Barry since the explosion, until Caitlin came back in. "You okay?" Caitlin asked and Kara nodded. "You want more time?'

"No, I don't want to get you into any trouble,' Kara said standing up. "I'll be back though when I can."

"I'm sure I'll be seeing a lot of you," Caitlin said, knowing the look in Kara's eye. Kara loved that boy. Just as much as Caitlin had loved Ronnie "Miss. Danvers?" Caitlin said as Kara was walking out. Kara turned around to look at Caitlin. "I couldn't do anything to save Ronnie, my fiancée, not even Superman or this Supergirl character could have saved him. I lost him and it was the worst thing that ever happened to me. I can see you love Barry just as much as I loved Ronnie. I'm promising you right now I'm not going to let you lose him. I'm not going to let you go through what I am. I'll bring him back to you."

"Thank you Dr. Snow," Kara said.

"Call me Caitlin," Caitlin said.

"Then call me Kara," Kara said and Caitlin nodded with a smile as she watched Kara leave. Neither realized they had just made a life-long friend in each other that evening.

Caitlin sat down back in her chair and looked at the TV. "Supergirl was seen near Central City catching a man who fell off a roof." The news anchor was reporting, "Superman was nowhere in sight near her. It seems this is the first time Supergirl has been out on her own."

"Interesting," Caitlin said, looking at the blurrily video of Supergirl saving the man and then shrugged. It was too early to make assumptions on the new superhero after all.

AN: Aaaaaand Kara is now Supergirl! Barry is in a coma and you got to see Caitlin. So will people stop asking me about Barry's powers now? Lol. He'll be up and about soon too. REVIEW.
