A/N: It's been a long time since I've been inspired to write something, and a SuperArrow fanfic just happened to be the thing running through my mind. I also have a SuperFlash fanfic that I plan on finishing at some point once life stops getting crazy, but I wanted to get something out there.

So to clear some things up, this takes place during Season 4 of Supergirl, but I'm changing things up bit since there were quite a few things I didn't like from Season 4. And regarding Arrow, Oliver and Felicity are no longer together, and I'd like to forget that they got married after Earth-X because it was supposed to be Barry and Iris' day. Plus, I kind of wanted to test it my writing skills with SuperArrow since Kara and Oliver are exact opposites in terms of personality. If you're wondering, Barry will show up at some point during this fic. Kara has her reasons as to why she went to Oliver on the matter.

So enjoy!

Earth-1
Star City

Everyone seems to think Star City is the perfect place for one to raise a family, or to find the next big job that will make you extremely rich. I'm here to tell you-don't come here. Not unless you want to be mugged every single night by notorious criminals. Or if you like chaos and destruction. And definitely don't come here if dim lighting makes you depressed, because you suddenly begin to lose hope

Star City isn't for everyone, but for me it suits me just fine. Why is that? Because my name is Oliver Queen. I spent five years stranded on an island with almost no way back. When I did return, my city was in shambles. In order to clean it up, I had to be someone else. I had to be something else. I'm the Green Arrow.

Oliver Queen rode his dirt bike throughout the streets of Star City, scouring the area for crime. It's what Oliver's Friday nights normally looked like, and while he would much rather be doing something else, the corruption of Star City wouldn't let him rest. He felt like this was a job he had to do in order to keep his friends and family safe. If only they knew the price and sacrifices Oliver had to make in order to keep that promise. As he continued to drive down the road, he heard static on his radio, meaning that Felicity Smoak was trying to get into contact with him

"I scanned the police radio five times as you requested." Felicity said. "I couldn't find anything for tonight. I mean, unless you want to stop a fire or stop a minor bank robbery but we both know that's not your style."

"So you mean to tell me that the one time I want to find someone to shoot with an arrow, there's nothing," Oliver gruffly spoke. "That's a first."

"Yeah, it's a shame," Felicity replied. "Look, maybe this is a sign. Maybe this is a chance for you to go home and relax for a bit. I mean, when was the last time you actually took some time for yourself?"

"Maybe a year, but I'm not interested," Oliver scoffed. "Besides, what could be more fun than finding bad guys to put away?"

"Maybe the fact some of us have a social life, and it's not all about crime," Felicity pointed out. "Besides, did you forget that I had a date tonight? I reminded you and Dig like six times."

"You did? Oops, must have slipped my mind." Oliver sardonically replied. Truth be told, it hadn't slipped his mind. He had remembered Felicity mentioned a date between her and another man last week, but every time she spoke about seeing someone else, it killed him inside. It had been a year since their breakup, and while Oliver poured his entire heart into his work, Felicity finally dating meant that she was ready to move on-without him. He didn't know if he could accept that.

"Sure it did, Oliver," Felicity said. "You know you need to start getting out there again. No one would think you're a bad guy if you did."

"I don't think dating is on my to-do list right now," Oliver rolled his eyes.

"Because you're fighting crime, right?" Felicity pondered. "I'm just saying, I would feel better if you found someone for you."

"Oh, I bet you would," Oliver smirked. "It would certainly take a load off your conscious. I get it, we didn't work out, and it was no one's fault.. While I am somewhat happy for you without being weirded out, I don't have the time to date right now. Right now, Star City needs me."

"Well tonight it doesn't need you and it certainly doesn't need me," Felicity responded. "Look, I have to go but if you want, we can try again tomorrow night."

"I don't have much of a choice," Oliver muttered. "Your date is waiting." There was some tension after Oliver mentioned Felicity's date, but she decided it would have been for the best if she had just left it there for the night.

"Goodnight, Oliver." Was all she said before the comms disconnected. Oliver silently cursed under his breath and ultimately decided to head to the Arrow bunker. It was lonely both at the loft and the bunker, but at least he could clear his thoughts and train.

Earth-38
National City

Flying. Some say that it's free-falling with style. I say that it's an anxiety-killer. I've never felt more free, flying through the air, clearing my mind, my heart, and my soul. Some would think I'd have a fear in flying after all I've been through. But I don't.

My name is Kara Zor-El. I was sent in a pod when my home of Krypton was destroyed. My pod got knocked off course and was ultimately discovered by my cousin, Superman. With my powers, I knew I could be something greater, so I decided to protect my world and the people in it by becoming Supergirl. I've had adventures along the way-even tried the romance department when it was decided for me that superheroes are incapable of being loved. But I loved my job no matter what. But in this instance, I had no idea that being Supergirl would have made my job the hardest it's ever been. Especially since being Supergirl, wouldn't have been good enough-and I would need help.

Kara Zor-El flew through the air in her Supergirl costume, taking in the fall breeze while looking down below at the city. She wished she could have said this was a leisurely fly, but she was actually reporting for D.E.O business. She had been called about an urgent emergency, and no one would tell her until she got to the scene. Once Kara saw familiar faces down below, she swooped down and her feet hit the ground with a large thump. Kara walked over and saw her sister Alex Danvers, and J'onn J'onzz on the scene. From the looks on their faces, it seemed solemn.

"Hey, so what are we looking at?" Kara pondered as Alex motioned towards the dead body in front of them.

"We have another alien death on our hands," Alex mentioned. "The one person that was willing to talk about what they saw said there was a small mob. They knew that he was an alien using a human's disguise and agitated him until he revealed his powers. Then they killed him."

"Do we have any information on the small mob?" Kara asked.

"Not really, but they did leave a peculiar mark on the alien that we wanted you to take a look at," J'onn replied. Kara walked towards the dead body and slowly pulled off the tarp, seeing that there was a symbol stamped on the alien's forehead. Kara furrowed her eyebrows and pursed her lips, which caught Alex's attention.

"What? What's going on?" Alex asked.

"This alien symbol has similar meaning to when the German's used the swastika on the Jews," Kara sounded heartbroken. "It's a hate crime against aliens. What I want to know is why they're targeting aliens?"

"We don't know," Alex sighed. "But I am concerned. This is the tenth alien death this month alone."

"Did all of them have the symbol?" Kara had to ask.

"They did, but we thought they were isolated attacks," J'onn explained. "It wasn't until we started piecing it together that we realized we have a hate group on our hands."

"Take the body back to the D.E.O for an autopsy," Kara said. "Also pull up all of autopsy reports on the aliens that had already died. I want to know for sure if they all died the same way." Alex realized that Kara seemed a little troubled, prompting her to place a hand on her sister's shoulder.

"Are you okay, Kara?" Alex asked.

"Not really," Kara honestly answered. "This is…, something I've never had to witness before. Frankly, it's scaring me."

"If I can find more information on the alien deaths, I'll be sure to let you know," Alex assured her. Kara nodded her head and started flying in the sky again, hoping to figure out some clues. As she continued flying she used her super-hearing pinpointed it was one of the T.V.'s that were sitting in the window of a shop. Kara flew down and stood there, watching a program with two men in a podcast setting-one that she recognized, and one that she didn't.

"Word was just reported that there was another alien death on the city outskirts, and all I can say is, good," The man spoke causing Kara to furrow her eyebrows. "Let them die, let them go away. All I can say is good riddance and let them get wiped out of our world. A world where there should only be humans. There's not enough room for the both of them. Ladies and Gentlemen, welcome to 'The Lockdown'. I'm your host, Ben Lockwood, and today, I have a very special guest with me. He agrees that aliens are filth, and that they all should be exterminated, with one in particular. Here is Mr. Lex Luthor."

"Thank you so much for having me Ben," Lex gave a smirk before glancing at the camera for dramatic effect. "Aliens are ruining this planet, and it's my duty to wipe them from existence. While we are unaware of who is killing all of these aliens, they are doing God's work, and making the world a rightful place. However, all of these aliens are flocking to National City because of one alien in particular. Supergirl. Everyone is fooled by Supergirl's "save the day" mantra, but in reality her mere presence in National City is the reason why all of these aliens are here, and in order for them to stop, we need to make sure that Supergirl isn't here. Supergirl thinks she's helping but in reality she is making everything worse, and if we continue to let her stay in our city, she is going to destroy the world. Now, I don't know how we are going to stop her, but she must be stopped."

"That I agree with Lex," Ben said. "If we let Supergirl stay in our city, she is just going to bring more filth here. Which is why I am working with the current president of the United States. We are going to get rid of the Aliens Amnesty Act and get rid of all of them once and for all. Starting with her. And if she doesn't leave peacefully, then she is going to have to be exterminated to set an example for all the other aliens living on our planet. We don't want you here…, so get out of town Supergirl."

Kara noticed there were people staring at her and she decided that was the best time to get out of everyone's way before they decided she was dangerous. She flew back to her loft and tried to stop the tears that were forming into her eyes. She couldn't believe that there was so much hate in the world, and that Lex of all people was trying to turn National City against her. Plus if Lex and Ben were to work together, she would have to worry about the countless resources Lex had in order to destroy her. The alien deaths that were happening were merely a message. If she didn't leave, she was going to have to deal with every single alien dying. She just couldn't allow that. While she knew she wasn't going to up and leave everyone, this job was just too much for her to bare alone. She needed some help-some superhero help.

She grabbed the small controller which allowed her to open the portal to the multiverse, but she had to think about who she was going to bring to Earth-38. Barry probably would have been scarred by all of the hate, so she couldn't go to him. She had no idea where to find Sara and the other Legends, since there were always traveling through time.

That meant there was only one other person who could help her save her city and prevent her from being run out of town. Someone as dark and not intimidated by the dangerous fight they were about to face. She needed Oliver Queen. She needed The Green Arrow.

Earth-1
Star City
The Arrow Bunker

Oliver exited the elevator that led to the underground bunker, ultimately taking his green hood off and placing the emerald mask on a nearby console. As Oliver started making his way to the small little gym he made for himself, there was a gust of wind behind him which indicated that Oliver wasn't alone. By instinct, he pulled his bow and arrow from behind him and readied the weapon, turning around to see who his intruder was. But once he saw who the intruder was, he immediately dropped the head, his eyes widening as if it were playing tricks on him. The person that was in his bunker was no enemy-Oliver wasn't even sure if he could call them a person.

"Kara?" Oliver blurted out, staring at the alien that was in front of him. Kara was one of his close friends, who happened to live on another earth. While her alien race knew her as Kara Zor-El and National City knew her as Kara Danvers, the rest of the multiverse knew her as Supergirl. Oliver and Kara had worked together quite a few times, whether it was to stop aliens or Nazi's. But it was after the Nazi trip that had Oliver a little bugged out. For one thing, his and Kara's Earth-X counterparts were married, and Oliver would have been lying if he hadn't wondered what that would have been like with the current Kara standing before him. Still, it wasn't the time for him to divulge into deeper feelings. By the look on Kara's face, it was obvious she needed his help. But there was another important question on his mind. "Kara, not that I'm not happy to see you here, but how...how did you get here and how did you know where I was?"

"Cisco gave me a device that allows me to travel through multiverses," Kara slowly explained. "It was meant to be for Barry, but...since you and Barry are on the same earth, I decided to pay Star City a visit. As for how I knew where you were, I bumped into Felicity while she was on her date and she said I could either find you here or at your house. I tried here."

"Of course you found her while she was with that guy," Oliver pinched his nose with frustration. "Where did you bump into her?"

"Some restaurant," Kara shrugged her shoulders. "It looked Italian."

"Of course," Oliver sighed before realizing he was getting off track. "Okay, um so what are you doing here? Why didn't you go see Barry?"

"This was something that Barry can't help me with," Kara crossed her arms with sadness. "It's a job only for you. But I need you to come to National City with me."

"You want me to go to National City, with you-right now?" Oliver slightly stammered.

"Would I ask you if it wasn't important?" Kara wondered.

"No you certainly would not," Oliver agreed. "So what am I looking at here?"

"Have you ever heard of a man named Lex Luthor?" Kara asked.

"No, I'm not familiar with your big bads of the day," Oliver shook his head.

"Right. Well, he is this ruthless person who had it out for my cousin back in the day," Kara explained. "Now he has it out for me. And with everything going on in National City right now, I can't face him alone without people thinking I'm some menace to society."

"Wait, but you're good, why would they think that you're a menace?" Oliver crossed his arms.

"Because along with Lex there's a man that thinks aliens are bad, and there's a gigantic army that is trying to get aliens out by force," Kara admitted. "They killed ten aliens so far, Oliver. And the group that is killing them left swastika-like marks on the dead bodies. This man is trying to convince National City that that they shouldn't be protected by one especially since they're afraid I'm going to turn on them, which is possible if Lex gives him the right tools."

"Like what?" Oliver couldn't help but ask.

"Like Red Kryptonite," Kara responded. "I know that Lex has some, along with regular Kryptonite and silver Kryptonite."

"That stuff could kill you," Oliver appeared concerned at this point. "Is there anything anyone can do to stop it?"

"If it falls into the wrong hands, no," Kara shook her head. "I could be on a warpath or I could die-or worse off I could kill the very people that I love. The whole world will make me out to be some killer, and that's not me. I don't want to be known as that because in reality, I'm supposed to be someone that provides hope. How can I provide hope when people are so quick to turn on me simply because I'm different than them? I can't deal with knowing there's alien blood on my hands simply because I refuse to leave." Oliver could hear Kara sniffle, and it was enough for him to slowly walk to her and place a hand on her shoulder.

"Don't worry, I'm going to help you," Oliver softly said as Kara stared at him with tears in her eyes. "I know how important your city and your family means to you. And I will be damned if someone tries to destroy your reputation." Kara didn't know the words to say, so she did what most weren't brave to do when it came to Oliver-she gave him a hug. Oliver wasn't known as a hugger but this time, he knew that Kara needed it. So he immediately placed his arms around her and comforted her the best he could. While Kara was hugging him, she felt warmth in her body, and her heart started to beat quickly. She slowly parted the hug and stared into Oliver's eyes, with the both of them unsure of what to say next. Did Oliver just have those same warm feelings too? She cleared her throat and slightly stammered while releasing a sad smile.

"I'm sorry, I know you're not a hugger," Kara softly chuckled.

"It's okay," Oliver prevented her from saying more. "You look like you needed it." Kara got out of his grasp and cleared her throat, pressing a button on a small remote. A small multiverse portal opened, causing Oliver to widen his eyes. "That's how we're traveling to National City?"

"Yep," Kara said. "Do you want to let your team know that you're not going to be here? I don't want them to think that you up and abandoned them."

"Um, I think they'll be fine without me for now," Oliver said. "I'm kind of going through some stuff myself and I just need to get away from them right now."

"I can understand that," Kara nodded her head before motioning towards the portal. "Come on." Oliver followed after Kara and entered the portal, the portal closing behind the both of them as they made their way to National City.

Earth-38
National City
Kara's Loft

As soon as Kara and Oliver stepped out of the portal, it took Oliver a moment to realize that they were in Kara's apartment. It had dawned on Oliver that he had only ever seen one side of Kara-her as Supergirl. He had never really gotten a glimpse of what Kara was like as Kara Danvers. He did have to say her loft was meticulously clean, and even somewhat cozy. He even noticed the pictures of Kara with her family members on the wall, and stared at them for a few moments. Kara looked happy in the pictures, surrounded by what he assumed was her mother, father and sister.

"Oliver?" Kara snapped Oliver out of his thoughts, prompting him to stare at her. He saw there was a small smile on her face, because Kara noticed he was glancing at the frames on the walls. "What do you think?"

"I think it's nice," Oliver said. "You have a better relationship with your family than I do."

"It's more complicated than you think," Kara looked down at her feet. Before Oliver could say more, there was a knock, one that caused Kara's head to whiplash to the door behind her. Kara used her x-ray vision to see who was at the door, revealing it to be none other than Alex. "Speaking of family, that's my sister." Kara opened the door and noticed the panicked look on her sister's face, causing her to walk into the loft while looking frazzled. "Alex, what's going on?"

"You have to turn on the news right now," Alex said. "As soon as I saw it, I was on my way here, and I had to tell you, and-" Alex's voice trailed off when she realized Oliver was standing right in front of her, causing her to clear her throat and turn back towards Kara. "...and I had no idea that you had company."

"Um, Alex, you remember Oliver, right?" Kara motioned with her hand. "He's from the same Earth that Barry is from. Oliver, this is my sister Alex."

"I remember him," Alex pointed with her finger. "He was at Barry and Iris's wedding. How was everything with that Felicity girl going?" Kara widened her eyes and glanced at Oliver, seeing he was biting his lower lip while trying to look away.

"Um, it's...not going." Oliver admitted. "We broke up shortly after the wedding."

"That's funny because Kara has been heartbroken since Mon-El left, and later came back to reveal he was married, and then left again-," Alex started rambling.

"Alex! What was it that you wanted to show me?" Kara decided to change the subject. Alex cleared her throat and turned on the television, with Kara and Oliver staring at the screen.

"Ben Lockwood, the guy that has that T.V. show 'The Lockdown', called a press conference to discuss rounding up the aliens," Alex explained.

"And the city just let him?" Kara balked at the idea.

"Apparently there are a lot of people that feel the same way that he does," Alex softly said. "I saw what he said with Lex Luthor on his show, and I know that must have scared you. But we're not going to let anything happen to you."

"I know." Kara nodded her head.

"So he and this Lex Luthor guy are trying to say that Kara's the reason all these aliens are dying, and that she has to go? What is with this guy?" Oliver cringed as Ben kept talking. "He sounds demented."

"Yeah, well most people who have no business being in power usually are," Alex said while her eyes were once again glued to the T.V.

"...They are not one of us-they are roaches who are infesting our planet, and they must be stopped!" Ben spoke from the T.V. "I don't know who is killing off these aliens, but I propose that this becomes a governmental funded program. It's vital to the way we live, and they must be stopped."

"How does he plan to do that?" Oliver questioned. "He sounds like a nut job."

"He's already in talks to work with the current president of the United States," Alex explained. "If that deal is done, then Ben is going to have a lot of power.".

"Power that is going to ruin the world as we know it," Kara added. "He has to be stopped."

"We will stop him," Alex promised. "In the morning. For now, you need to get some rest."

"Wait, so Kara is just supposed to sit here and get rest while this Lockwood guy tries to exterminate all aliens?" Oliver furrowed his eyebrows. "That doesn't sound like it's going to do any good."

"Don't worry, Kara has the best team out there," Alex assured him. "Remember, the D.E.O. is on her side. They'll work all night if they have to, making sure that Kara and every other alien life form is safe." It seemed like a good enough answer for Oliver, which was why he decided to let it go. "All right, I'll see you in the morning Kara."

"Okay," Kara nodded her head. Alex started making her way to the door before turning around and pointing to Oliver.

"By the way, he's cute." Alex simply said.

"Goodnight Alex." Kara feigned a smile while waving at her sister. Alex turned around and left Kara's apartment, leaving Oliver and Kara there in bewilderment.

"Well, that wasn't awkward at all," Oliver couldn't help but jest.

"Yes it was," Kara chuckled. She looked at the time and realized she needed to get some sleep, prompting her to walk towards the closet and grab an extra blanket and pillow for Oliver. "Are you going to be okay on the couch?"

"Yeah, I'll be fine," Oliver assured her. "I've slept in worse places." Kara didn't say more as she handed him the blanket and pillow, Oliver taking it with appreciation. "Thank you."

"You're welcome," Kara nodded her head. "If you need anything, I'm in the other room."

"I'll try not to bother you," Oliver replied. He noticed the worried look on Kara's face which caused his face to become worried. "Are you okay, you seem troubled."

"The whole Lockwood thing has me on edge, but...I'll be fine," Kara said.

"You know, if you want, the Green Arrow can visit Lockwood and rough him up a bit. A bow and arrow is quite persuasive," Oliver suggested.

"As honorable as that sounds, I can't have you do that for me," Kara shook her head. "I don't want you making yourself Public Enemy #1 because you want to rough up Lockwood. We all want to rough up Lockwood, and wonder why he's doing what he's doing. But...we just can't. All we can do for now is to let Alex take care of it. Supergirl will take care of it tomorrow."

"Okay, I'll respect it," Oliver promised. Kara nodded her head and started making her way to the bedroom. "Goodnight, Kara."

"Goodnight, Oliver, sweet dreams." Kara responded before retiring to her quarters for the evening. As soon as Kara left, Oliver tried to get himself comfy on the couch, but he was having a hard time with the whole Ben Lockwood situation. Plus, Kara's fears about having Kryptonite being used on her was valid, considering Lockwood would have all the resources needed to destroy her. He could see why she needed his help. This was something Kara needed him for.
