Hello and welcome to 'Connections', a crossover of Supergirl, Arrow, and The Flash. This is not the first story I have written, but the first that I have posted anywhere online. I am not a professional writer (and am nowhere near one) so if there are any mistakes or anything wrong, please don't be mean. I have already completed this story and am ready to update but I want to see how this chapter goes first.

I do not own Supergirl or Arrow or The Flash! Characters you do not recognize are of my creation!

Chapter One

Kara Zor-El, known mostly as "Supergirl", is an alien refugee on Earth. At the age of thirteen, her home planet, Krypton, was dying and her parents sent her in a pod to Earth. But before she was able to get out of the blast radius, Krypton exploded, and she was knocked into a place called the Phantom Zone. In the Phantom Zone, she did not age, nor was her pod able to fly out. It was thirty-five years until she got free. She landed on Earth exactly how she left Krypton, a thirteen-year-old girl. Her cousin, who was a baby before they left Krypton, found her and brought her to the people who raised him, the Danvers. They were a family consisting of a mother, Eliza; a father, Jeremiah; and a fifteen-year-old daughter, Alex.

Kara was an alien, but the Danvers took her in and raised her. They helped her control the amazing powers she was granted with, and for the powers her eyes held, Jeremiah gave her a pair of glasses laced with lead, something her powers couldn't see through. She grew up alongside Alex as sisters and everything about Kara, to everybody else, seemed normal until one day when she had to reveal her powers to save her sister. Ever since then, she has been known as "Supergirl" or the "Girl of Steel".

One incident, four years later, caused everything to change, again.

While soaring over the National City Museum of Artifacts, Supergirl heard, with her super hearing, in the distance coming from the National City Bank. She flew to the scene, her long blonde hair moving crazily in the wind. Since bullets bounced off her, she swooped in, landing a few feet away from the robbers.

"Hey! What's the hurry?" she said loudly over the gunfire, seizing it immediately. Stupidly, the robbers turned and began firing at Supergirl. The bullets didn't do any harm to her, so she walked towards the robbers. Grabbing hold of the first man's gun, she crushed it in her hand and punched him out. She did the same to two other guns and robbers, but before she could reach the final robber, he changed his bullets and took a shot at her. Instead of bouncing off her, that bullet went straight through. She stopped in her tracks and looked down as blinding pain ran through her body. The bullets he was using were laced with Kryptonite. As she fell to her knees screaming in pain, he paraded towards her, pulled her head up, and stared into her eyes as he shot her once more in the leg, shoulder and again in the chest.

Falling to the floor and barely keeping her eyes open, she watched the Department of Extra-Normal Operations (D.E.O.) arrive. Before anyone could reach Supergirl and the last robber, he poured liquid Kryptonite over her vulnerable, weak, dying form as he stepped back and watched her scream. Kneeling next to the hero, he raised the Kryptonite gun to her head and finally spoke.

"Come closer, and she gets a bullet in her head!" he said as the agents were closing in. "And don't even think about shooting me!"

"Okay, we can make this work." Alex, who is also the director of the D.E.O., said as she was scared for her sister's life. "All you have to do is lower your weapon and step away from her!"

"And why would I do that?" the robber answered. "This is more fun."

"Hurting her is fun? Why would you say that?"

"It's fun because she spends her days flying around and saving people, saving people from getting hurt," he yelled. "I want her to feel pain! I want her to be hurt! I must do this. After what she did to my sister! She took her away from me!"

"Trust me, she gets hurt a lot. Supergirl lost her family, her friends, and her planet, all in one day. She saves people for the ones she couldn't. The man she loved was sent into the future, married someone else, came back, and was murdered, and her best friend was taken into space. She has been taken to another planet, kidnapped more than once, tortured, and experimented on, all for the same reason of what you're doing to her now because she couldn't save that person's loved one."

"She deserves this, then. The 'all-powerful' Supergirl is supposed to be a hero, but to me, she sounds like a killer." he claimed. He stood up, drew back his leg, "And everyone can watch her suffer!" Letting his leg swing, over and over, about six or seven times, he kicked Supergirl in the ribs. Blood began to drip out of her mouth. Once he was happy, he stopped kicking her, knelt on one knee, and, once again, raised the gun to her head.

"Now that you saw that," he added, smirking at Alex. "You will see me kill this city's beloved hero!" he finished. Before he could squeeze the trigger, Supergirl grabbed the gun, crushing it to thousands of tiny pieces, including the Kryptonite bullets.

"Take the shot!" Supergirl yelped as loudly as she could. Seeing his weapon destroyed, he punched her in the face, right before many D.E.O. agents shot and killed him. As his corpse fell on Supergirl, she lost consciousness.

5 days later...

There had been no progress on identifying the robber, or any of them, crime was through the roof, everyone at the D.E.O. was on edge, and yet Supergirl still hadn't woken up. Most people thought she was dead, but that was not it. You aren't dead until your brain stops, and Supergirl's brain hadn't stopped.

Inside her head, Supergirl was having a vision, almost a dream. She was seeing a girl who looked exactly like her seventeen-year-old self, though it wasn't her. It looked like she was at a school assembly, but not like the ones she had in Midvale. She also saw a green bomb. She couldn't hear anything until the look-alike stood up and walked to the front of the assembly. Once the girl was at the front, Supergirl saw herself crash through the ceiling and heard that had everyone to evacuate. The D.E.O. was at this place as well. They didn't stop anyone from leaving, but they did shoot Supergirl with a dart she knew was filled with Kryptonite. It was weird, as she was shot with the dart, it was like the look-alike was shot with one, too, as she also felt the pain. The D.E.O. got closer to Supergirl, and as she tried to fight, they put the special handcuffs, full of Kryptonite, on her hands.

The look-alike tried to get them to leave Supergirl alone, and when they didn't, she fought them with strength a seventeen-year-old girl shouldn't have. So, they shot her with more than one of the Kryptonite darts and used the same handcuffs. It was too much Kryptonite, and the look-alike fell unconscious. It felt so real.

As she awoke, Supergirl scrunched up her face for she realized just how much her body hurt. She was bathing in the light the yellow sun lamps were emitting as she lay on one of the beds in the medical bay at D.E.O. headquarters.

"What happened?" she groaned as she tried moving her arm. The many saddened people surrounding her perked up as they saw her bright blue eyes flicker open.

"Kara, it's okay," Alex and Eliza said. "We're here. Please don't try to move."

"Too late!" Kara winced as a spike of pain ran up her arm. This is also when she noticed where she was, and who were surrounding her. All around the medical bay were dozens of flower bouquets, 'get better soon' cards, presents, and chocolates from all the D.E.O. agents and staff, from friends of friends, and fans. This is when she recognizes the faces smiling at her. Her cousin, Superman or Clark Kent, J'onn J'onzz, Brainy Dox, and her best friends, Nia Nal, James Olsen and Lena Luthor, were all there. It was everyone she loved.

Clark is also a refugee on Earth as he was also living on Krypton. He was only a baby when Krypton died, and luckily, his pod made it out of the area before Krypton exploded, and successfully landed on Earth. When he arrived, the Danvers family found him and took him home. They raised him as a son, even though he was an alien.

J'onn J'onzz is a Green Martian and is the Last Son of Mars. Jeremiah Danvers helped him and killed the man hunting J'onn. He can shapeshift, changing his appearance at will, and to make things not look suspicious, he took the skin of the hunter, Hank Henshaw, who was the Director of the D.E.O. at the time. Now, he has stepped down from that position, and became a Private Investigator, working for himself, but he is always happy to help Alex and Kara, the two people who are the closest things he has to daughters.

Querl "Brainy" Dox, also known as Brainiac 5, is a twelfth-level intellect, originally from the League of Superheroes, but he stayed behind to help Kara and the others out of sticky situations. He has become a friend, and someone very trustworthy.

Nia Nal recently started working at CatCo Worldwide Media, the same place Kara's day job is. At first, Kara thought that she was just a sweet girl diagnosed with Narcolepsy, but that wasn't the case. Nia has dream powers, which is why her superhero name is Dreamer. She can see what is going to happen to the future through her dreams. Kara showed her that she was Supergirl, and decided to take her under her wing so that she could learn the ways of both reporter-ism and superheroism.

James Olsen was Clark's best friend, who were both living in Metropolis, before he moved to National City to look out for Kara, on Clark's request. Kara and James immediately became friends. He has also helped her out when she needed it and was there when she needed someone other than Alex. Last year, he took on the role of a vigilante named Guardian, who soon was recognized as a superhero. Yes, he was human, but he had a suit made from titanium. Soon after, he was arrested for vigilantism and isn't allowed to go out as Guardian ever again, if he wants to be a free man.

Lena Luthor, the younger sister of Lex Luthor, the C.E.O of L-Corp, and owner of CatCo Worldwide Media, was and is always on Kara's side. She was friends with both Kara and Supergirl, even before Kara revealed her powers. They had been through a lot, and either Kara or Supergirl was always at Lena's side if she needed someone to talk to or a hug. The two officially met when Kara went to investigate an explosion on a spacecraft. They then met later, like Supergirl, and Lena was adamant about showing the superhero that she had no part of the plan.

"Kara, you were attacked when you were stopping an armed robbery," Alex explained to Supergirl and everyone else in the room. "One of the robbers had Kryptonite laced bullets, shot you four times, and poured liquid Kryptonite all over you."

"He was threatening to shoot you in the head," Eliza was saying as she knew a little more than everyone else. "He kicked you and broke four of your ribs, and he punched you in the face, causing you to fracture your skull. Kara, honey, you could've died!" she said as tears began forming in her eyes.

"You did die, Kara, three times," Brainy said. "I am checking your vitals, as you're now awake, and you seem to be slowly healing, faster than any human, but slowly for a Kryptonian. There must still be Kryptonite here, it is either that there are still traces in your blood or somewhere near you."

"I haven't ever felt this much pain before," Kara grunted through her clenched teeth.

"Oh, I'm sorry! I forgot to turn off the Kryptonite emitters." Alex said as she saw her sister in pain. She walked into the observation room and turned off the emitters; walking back to the main room, she explained her actions. "We didn't know if when you woke up, you'd be a threat to any of us here, or yourself."

"No, that doesn't seem to have worked," Brainy responded as he was checking Kara's vitals again. "You aren't healing at your normal speed."

"Okay, I'm very happy to see that you're awake, Kara, but I have to get back to Metropolis," Clark told his cousin with the deepest regret. "Duty calls. It was nice to see you, all of you guys. I just wish I could stay and help you get your city back in control. Thanks for saving my cousin, Alex. Got to go!" he said before he used his super speed out the door.

"What did he mean by 'get my city back in control'?" Kara asked her sister, her weak voice sounding a little panicked. "What happened? How long has it been since the fight?"

"Five days," Alex confessed while looking around at the others. "It has been five days, and the city is both depressed and chaotic. Without Supergirl, the amount of crime has almost tripled. But we have been doing our best to stop it." she was saying as another agent walked in, holding an iPad the agency used.

"I'm sorry for interrupting, Director Danvers," the black-haired agent said. "But, a C-4 bomb alert just ran through the system!"

"Where is it coming from?" Alex asked sounding very serious.

"Northwind High School in Landing City."

"Is there anything important happening there today?"

"Yes, today is the first day of the school's award ceremony. Parents, families, and friends were all welcome. There are going to be many people there."

"Okay, get my team, and two other teams together to move out in two minutes. We'll be using helicopters, so tell them to meet at the hangers."

"Yes, ma'am." the agent responded, before turning and walking, at a swift pace, out the door.

"Kara, you are staying here!" Alex ordered her sister. "The five of you, I am counting on you to keep her here. And Kara, if you show up there, I will arrest you and lock you in a cell until you're completely healed!"

"Fine, Alex, whatever you say," Kara replied to her sister, though she knew that she was still going to go, no matter what Alex's orders were. "I'll stay here."

Alex gave her sister a 'thanks for understanding' look before she turned and walked out the door. Through the open doorway, you could see about fifteen agents gathering their weapons and gear and following Alex to the hangers. Kara lay in the medical bed, listening for the helicopters to fly out of earshot. This is when she got up.

"Kara, you can't go out there!" Lena exclaimed as she saw her best friend stand up. Everyone in the room stood up, ready to try to stop her.

"Kara, please, lie down," James asked, approaching slowly.

"You need to rest," Nia told her friend. "You would be telling us the same thing if we were going against what Alex said."

"No, I have to go out there," Kara refused. "I have to help and save people from that bomb."

"Kara, you need to rest." J'onn restated Nia's statement.

"What if the bomb goes off while Alex is there!" Kara yelled. "What if that bomb kills her, and I wasn't there to save her because I was here! No, I am going to help my sister." she finished saying, right before she darted for the door.

Walking out of the medical room, everyone turned and applauded, until J'onn told everyone to not let her leave, then everyone tried to grab her. Kara fought the agents, apologizing after each punch. She then used her super speed to get to the balcony, where she was able to take off.

While flying over the city, she was isolating the sound, searching for the murmur of the helicopter engines. Once she found what she was looking for, she combined her super speed and the speed of her super flight and raced to the school.

Once she arrived, she noticed that, somehow, she arrived at the school before the helicopters. She was hovering over the school when she saw the helicopters quickly approaching. They would be here in two minutes, but she didn't have time to wait for them. She used her super-hearing to listen to the speaker in the school while scanning the surrounding area for any signs of an explosive. That's when she saw it, the bomb was the same one in her dream. She landed where the bombers were, knocked them out, and tried to defuse the bomb. When that didn't work, she flew up so that she was over the school theatre, and crashed through the ceiling. There were so many people in that room, so she told everyone to evacuate the school. It took a moment for everything to register in the minds of the many, then complete chaos unravelled. With people running in every direction, she could easily make out the figures of about eleven or twelve D.E.O. agents, along with Alex, storming the large room. They did not stop anyone from leaving, but they did aim their guns at Supergirl.

There was only one way to hurt the superhero and the D.E.O. knew what it was. When J'onn was the director, though they were friends, he had special darts, injected with liquid Kryptonite, made to subdue Supergirl in case she ever turned against the city again. Alex told Kara that she would destroy those darts, but she didn't.

Alex had armed four of her agents with guns holding those darts, and told them to only use them if she would not stand down, and only on her order. "Supergirl, I told you to stay at headquarters! You are disobeying direct orders."

"I'm sorry, Alex," Kara saying, her eyes very full of her thoughts. "But I couldn't let you come here by yourself. What if the bomb blew up while you were still here!"

"Stand down, Supergirl! If you do not, these agents are going to have to use extreme force to make you comply."

"Alex, you know I can take you and everyone out with… wait… Alex, you said you would have those destroyed!" Kara said as her blood began to boil, feeling betrayed.

"I know, but I couldn't, I had to have some way to protect the city from you if you ever went rogue. Please, stand down. And I'm sorry, too, but Supergirl, you are under arrest for the many counts of assaulting federal agents, as that is the only way J'onn and the others let you pass." Alex stated.

There was a bystander to this conversation, a girl, about seventeen, who Alex recognized almost immediately. She looked exactly like Kara did at that age.

Agents approached Supergirl, and put power-weakening handcuffs over her hands. At the sudden jolt of Kryptonite the handcuffs were emitting, Supergirl fell to her knees as she felt her powers being sucked out of her. At this, the girl standing behind the superhero was, somehow, affected, also on her knees, and feeling the pain. She fought through that, stood up, and approached the agents and superhero.

"What are you doing to her!" she exclaimed. "Leave her alone!"

"I am the director of the FBI," Alex told her. "And you need to stand back."

"And you need to leave her alone."

"Supergirl has been arrested for-" Alex was saying.

"I know, I heard your excuse," the girl interrupted. "Supergirl has done so many things to help her city, and now you're arresting her? How twisted can the government get!" As she was speaking, she watched the agents fidget.

"If you do not stand down, you will be arrested for interfering in a federal offence."

"I will not stand down, I haven't done anything wrong!"

"Alright, you two," Alex pointed at two agents near the entrance of the stage. "Will you please put handcuffs on her." As they approached, the girl continued to stand her ground. They kept getting closer and closer until she started to fight them with strength a seventeen-year-old girl shouldn't have. She punched and dodge the agents until three more agents came to join in.

The way she fought was like the way Kara did. She was too strong when she was hit, she wasn't hurt, and her stance was exactly like Kara's. An idea to subdue the girl popped into Alex's mind. "Shoot her with the darts!" she commanded her agents. Once the guns were lined with the girl, the four agents fired.

Colliding with her skin, the girl stopped dead in her tracks and fell in a screaming lump on the floor. The agents fighting her were able to grab her hands and put the same handcuffs, as Supergirl's, on her.

She was risen to her feet, being supported by two agents, when the same jolt of Kryptonite surged through the girl's body. The pain was too much for her to handle, having her lose all sentience.
