This is an AU Story
I DO NOT OWN Supergirl, Flash, Arrow, DC's Legends of Tomorrow, or any other DC related characters.
Timeline
The events of Flash Season 3, Supergirl Season 2, Arrow Season 5(Assuming William's mother didn't survive Lian Yu), DC's Legends of Tomorrow Season 2 all occurred in this universe. The only real difference is that they all transpired in the same universe. Only Earth 2 (Harrison Wells, Jesse Quick,etc) is the other parallel universe they know of.
Wonder Woman, Green Lantern, Batman, and Superman will also be in this story. Let's just imagine that they inhabit the same universe. The justice League was also formed after the Dominator Invasion so that the Earth could be defended from large scale. Every hero in the Arrowverse is a member. For story reasons let's say that the heroes were too overwhelmed with their own individual villains, so they couldn't help Supergirl with the Daxamite Invasion.
I edit the chapter because I believe my new addition will add to the overall story. Sorry for not updating, I've been studying for my college classes.
Barry needed more than just a run to calm him down, he needed a friend and he knew where exactly to go to. Barry was determined to pay the Emerald Archer a visit. As he made his way to Star City, Team Arrow was dealing with their own problem.
"Is everyone in position" the green Arrow said. He heard 4 yeses from his coms. They came from Wild Dog, Black Canary, Spartan, and Mr. Terrific.
"Give him hell guys" Felicity said through the coms. By "him" she was referring to Vigilante who has been on a killing spree the past month.
Team Arrow slowly made their way inside a warehouse to finally arrest Vigilante. They knew the weapons deal that would occur was too good to pass up for Vigilante.
Standing behind cover they were surprised to see that no one was in sight
"Crap" Oliver thought "It's a trap". As his thought finished five mounted turrets began firing at their cover.
"You guys probably have him surrounded I almost feel bad for him. You'd think he'd learn to give up his crusade after targeting you Oliver, but nope here he is in some creepy warehouse hunting criminals. Where does he get all the money for the bullets, does he just have it lying around? Oh, what if he's rich like you Oliver wouldn't that be cool I can picture the headline ones he's arrested "Billionaire Arrested For Vigilantism". You know for the longest time I saved that for you, but who knows this guy might be the first to receive it"
"Felicity honey what did we discuss about you speaking while in the field"
"Ok fine Overwatch out" with that Felicity let the team get to work
Oliver got three explosive arrows from his quiver, aimed them at the turrets and let go. The three arrows split off and destroyed their intended targets. The remaining two were soon taken out by Dinah's canary scream.
"Overwatch any sign of the target" Oliver asked
"None that I can see, you guys might just want to come back, we have a visitor"
Oliver sighed "Ok, lets head out" Everyone nodded and they soon made their way to the Arrow Cave.
"Ok Felicity who's here" was all Oliver said before noticing the familiar man standing beside Felicity
"Hey Oliver" Barry waved "Long time no see"
Oliver rushed the man and pinned him to the ground "Who are you?"
"It's me Barry, let me go Oliver"
"How could you let him roam freely Felicity he could be another doppelganger for all we know, we can't have another of our friend's image be tainted"
"Jeez Oliver, it's me Barry Allen I'm from this earth"
"Prove it"
Barry sighed "When we fought the second time here in Star I kicked your butt"
"Not good enough try again" Oliver replied and broke one of Barry's fingers
"Ow ok that's enough" He threw back Oliver and began Vibrating his hand and in a second his finger healed and was back in position.
"Oliver, I came to you the very day I woke up from my coma and you told me the lighting chose me, there is that good enough for you?"
"Barry its really you" Oliver hugged his friend and soon everyone else hugged him as well, he told them about his experiences in the Speed Force. As soon as he finished everyone was speechless.
"Barry I can't imagine all you've been through, but one thing is clear we need to celebrate your return. Oliver why don't you call the whole league to throw a party." Felicity said to break the silence
"Felicity we only unite the league when there is a serious threat"
Felicity gave him a look
"Ok I guess we can make an exception for the return of a founding member" he mumbled
"Oliver, I didn't hear you"
"I said I guess we can make an exception for the return of a founding member"
"Good now get to it"
Oliver left the room to make some calls, while everyone laughed at how easily the brave Green Arrow listened to her suggestion
"So, Barry what brings you to this side of the world" Felicity asked
"I actually came to talk to Oliver, but he currently is occupied so why don't I talk with you in private. I know you'll eventually make him tell you."
"Ok sure step into my office" she said pointing at her workspace.
Every member of the team said their good byes and headed home.
"So, what's up Doc?" Felicity asked
"We'll you see I sort of left some info out when I talked about the Speed Force"
"Ok such as?"
"We'll for the most part it made me realize that I love Kara and love Iris as a sister"
"Wow that's quite a lot you left out. So, umm what made you realize you love Kara?"
"Well in my many lives I decided to give her and I a chance and I realized I was always deep down in love with her smile, her amazing blue eyes, and just her whole personality in general. I spent a lot of happy lives with her, and I just knew I had to get back and make it a reality"
"Well good luck, if it makes you feel any better I always hoped you and her would fall in love your both very similar people" she hugged her friend one last time
"Thanks, and it does, we'll I should get going say bye to Oliver for me"
"Will do"
And with that he made his way back to STAAR not wanting to confront Joe just yet.
The next day he greeted Joe at his home and told him about what he'd endured
Joe hugged his son "Well it's good to have you back Barry"
"Good to be back" he said after the hug. "Is Iris home?"
"No, she didn't come back yesterday"
"Oh" Barry said feeling guilty about his decision to tell Iris how he felt.
"Joe can we talk I have something to tell you"
"Sure, sit" Joe pointed to the chair
Barry sighed "There's no easy way to tell you this, but I don't want to marry Iris anymore"
"Why not? Weren't you always in love with her?"
"I was, but I've come to understand I'm in love with …"
"Kara" Joe cut him off before he could finish his sentence
"How did you know?"
"Barry a father knows. When you first mentioned meeting Kara you had a glow that showed you were smitten by her"
"Really? I only just felt this way towards her recently"
"Don't lie to yourself we both know that deep down you've always loved her. You might have been afraid to admit it to yourself at the time but you did"
"So, you're not mad I don't love Iris anymore?"
Joe held his hand up "Barry I want you to be happy, and if it's not with Iris so be it, you can't help who you fall in love with. Just do me a favor" Barry nodded "Don't let Iris get too far away she's your sister and best friend, she'll eventually come to her senses. I want her to also be happy so help her out ok?"
"I'll be there for her" with that confirmation Joe hugged his son one last time before he left to visit a certain blonde in National City.
Unknow to both of them Iris had come back home and heard their whole conversation and filled with rage left the West household to give Kara a piece of her mind.
After knocking Barry waited outside Kara's apartment. The door would soon open and reveal Kara was in a blue dress. Barry couldn't help but think she looked so beautiful.
"Hi Barry, what are you doing here?"
"I was coming to see if you wanted to go eat"
"Barry, you do know what today is right?" she asked
"Ummm no"
"Why it's your welcome back party, where's your suit?"
"I umm left it back home, I didn't want it to get ruined" he lied
"Ok so guess I'll see you there then" she locked her door and was ready to leave when Barry said "You know I can take you there, I'm 5 times faster since we last met. I could carry you there if you wanted"
"Sure, it sure beats flying with this on"
"Ok" He began to carry Kara in a bridal position, and Kara couldn't help but blush.
"Well get ready it's going to be a bumpy ride" with that he made his way to Central city.
With Kara so close his heart began racing. Kara could hear it but just assumed it was because he was running. They made it to the hall of justice in 2 minutes.
"Wow, you weren't kidding about your new speed. I'll be inside you should get your suit" Kara made her way in.
Barry then attempted to concentrate and picture a nice suit. He'd been working on trying to manipulate the speed force. He concentrated more and more, and soon found himself in a nice three-piece black suit with a tie. "Maybe with a bit more work I can do it effortlessly" he said to himself before going in.
Inside he was greeted by every member of the league, he politely thanked them for their concern and told them what happened. When he told them, he couldn't help but look at Kara's warm smile. As soon as he finished he made his way to Kara to talk to her.
As soon as he tried to say something Iris walked in screaming for Kara.
"Iris what wrong?" Kara asked
"What's wrong is that you're taking away my Barry!"
"What do you mean? Taking Barry?"
"Don't play innocent with me I know he's in love with you"
"He is?"
"Yes, he told me he didn't love me and I overheard him say he loves you"
Kara couldn't help but glance at Barry. She couldn't believe her friend thought of her like that.
"You probably made him cheat on me, you seduced him didn't you, you bitch." Iris then proceeded to slap her. Despite not feeling the slap, Iris words really hurt her. They gotten so close these past months only for them to end like this.
"Stop Iris. Kara is the nicest and bravest person you will ever meet, she would never seduce me. I love her, and I had hope you'd understand as my sister, but it's quite clear you don't. Get Out! Before someone else makes you get out"
"I'd listen to him if I were you" Superman said his eyes glowing red from his laser vision.
"Fine but I want you to know Kara that he'll one day see you for what you truly are, a bitch"
"GET OUT!" Barry yelled with that Iris finally made her way out.
Kara broke down and began crying because her friend hated her. Barry held her tight telling her "It's not your fault, it's mine I should have told her in better terms." He hated to see her cry.
He thought of how to cheer her up, and it was quite simply. He had to ask Hal for a construct piano.
He began the melody he remembered from Kara's and his time in the Music Meister's musical.
[BARRY]
At times like these when life is getting me down
And the world seems like it's gonna end-ship
There's at least one power that we both still have
And that's the power of
[KARA]
''Friendship'' said with a small grin
[BARRY]
I'm your super friend
Your super friend
I'll be there in the nick of time
If you're ever in a spot
[KARA]
And if not there in time
You can just go back in time
And give it another shot

[KARA]

[BARRY]
Sing!
[KARA]
I'm your super friend
Super friend
[BARRY]
When you need a compliment
I can rattle off a dozen

By your more famous cousin
[KARA]
Thank you! No one ever says that!

I'm your super friend
Super friend

[BARRY AND KARA]
I'm your super
(It has a double meaning!)
Friend!
As the song finished he and Kara were face to face each feeling the others breath. As he attempted to lean in and kiss her Oliver interrupted him.
Oliver cleared his throat "As much as the rest of us enjoying hearing you sing, there's a more concerning issue
"What's wrong?" they both asked
"While you two danced and singed Felicity detected an energy signature, it seems to be very similar to that of time travelling"
"Nice, it could be the return of the Legends" Barry optimistically said
"Or it could be a new threat" Oliver said
With that said the whole league ran outside just in time to see a Kryptonian pod landing, but it wasn't any pod it was Kara's. A man stepped out, he was wearing a suit which was similar to that of Superman's (CW suit) except for the fact that his was all red and had a blue cape and had the face of a man they all thought they'd never see again. It was Mon-El.
As Kara realized who it was she ran towards him and he towards her and they kissed.
"Mon-El where were you?" Kara asked after the kiss ended
"Well your pod took me through a wormhole which took me to the future, I became a hero, joined the Legion of Superheroes saved the universe countless times, kicked some ass while doing it all while my friend Brainiac Five determined a way to readjust the pod to bring me back" Mon-El said
"Clark, Brainiac says hi" Mon-El said
"Wait you knew of this Brainiac?" Kara asked
"I may have fought alongside him and the Legion when I first started out, I honestly didn't think to check and see if Mon-El was in the future. It's good to have you back" Clark finished his statement with a hug
Everyone then went back inside and celebrated their two lost friends return.
When the party ended everyone went home, as Kara and Mon-El slept on their bad together, he couldn't help but think of Brainiac's last words.
"She won't always be yours"
