"You're getting pretty good at this," Kara commented, as Marley avoided Kara's punches.

"Thank you. I have the best teacher," Marley replied, slowly getting out of breath.

"No problem."

Mon-El walked into the room, staring at Kara, waiting to ask about Brainy's whereabouts.

"Hey Kara have you seen Brainy recently?" he asked.

"No I haven't," she said, dodging one of Marley's blows, "You should ask Winn. Those two have the same mental capacity."

"Okay," Mon-El replied.

"Hey Marley! I also have a question for you too," Mon-El said, greeting her.

"For me? Okay what is it?" Marley asked.

"Have you seen Mxyptlk?" Mon-El asked.

"Yeah, he's currently not on Earth right now. He'll probably come back this afternoon or so," she replied.

"Thanks. Oh, and keep up with the good work beating Kara," Mon-El mentioned.

"Hey! I kicked your arse quite well," Kara said, calling out loudly.

"It still pains you know," Mon-El replied, smirking.

Kara's eyes went a little softer, as she remembered the memories before Mon-El left.

Mon-El immediately realised and walked to the door.

"OK see you two around," he said.

Marley saw Kara's weird behavior after Mon-El left. She already knows the story but she's still curious about what her sister feels about him.

"Hey you alright?' Marley asked.

Kara said, sweeping her tears, "Yeah I'm fine."

"Doesn't seem like it. Wanna talk about it?"

"It's just... things are so different now. Remembering those memories just, just makes me wish I could go back time and change what happened. But I know I can't, because I don't want to mess with time. Messing with time is a bad thing."

"You should tell Barry that," Marley said, trying to sound humourous.

"Nah, he's too busy messing up his timeline."

"Of course he is. By the way he seems to be a really nice person, and you've known him for quite a while now," Marley said.

"I think I know what your intentions are but he's married so... yeah not a chance," Kara told her.

"But what if he wasn't married, hmm?" Marley said, being mysterious.

"Well I suppose I would've... possibly dated him."

"Hmm... Good to know. Oh and I ship you with him," Marley chucked.

"Are you should you're my twin?" Kara asked.

"Positive," Marley replied.

"I mean he has good looks, is really smart and is a meta-human with superspeed, but we live on different Earths. I guess part of me has a small crush on him, but I still am in love with Mon-El," Kara added.

Marley's mouth and eyes opened wide, "You have a small crush on him? You two look cute so cute together. You've known each other for so long, and you know do much about him. I don't even know that much about Mxy."

"Wait really?"

"You're curious now," Marley remarked.

"Yes I am. And for your information, you haven't told me you and Mxyptlk's tales."

"Oh so let's go back down memory lane," Marley joked.

"First let's sit. My legs are hurting me," Kara said.

"As you wish."

"Now begin please," Kara said

"Okay," Marley nodded.

*MARCH 20 2016*

It was just a few months after Marley had started the new high school year, when Mxyptlk a.k.a Max Thomas Wood came. Clean shaved, dark brown, curly hair, light brown eyes and an adorable smile.

Mxyzptlk moved into the neighborhood where Marley's apartment was.

The first encounter happened when he was singing in the shower, which was the opposite side of their apartment.

Marley knocked on the wall, "Could you keep it down please!"

"Sure," Mxyzptlk mumbled from the other side.

After a few moments of silence, he began again.

"I came in like a wrecking ball," Mxyzptlk sang in a girlish tone.

"Oh no."

Knocking on the wall again "Excuse me! Let me shower in peace!"

"Sorry!" came from the other side.

After all was done and dusted, both got ready for the day and walked out of their apartments.

As Marley was locking the door of her apartment, she noticed him. Standing there struggling with his keys, trying to close his door.

"Hey, you need some help?" Marley asked.

Mxyzptlk didn't say anything and looked at her. She looks like Kara. OMFG! How can she be here? Mxyzptlk thought.

"Excuse me?" Marley asked again. Mxyzptlk didn't reply as before.

Marley took the keys from his hands and locked his door, slowly passing his keys back, distracted by the look he was giving her.

"Are you even going to say THANK YOU?" Marley asked sounding really pissed off.

"Umm... I'm sorry. I... What's your name?" Mxyzptlk asked.

"Marley. Marley Rose," she replied

Yes she is, Mxyzptlk thought, "Thank you Marley Rose."

"Just Marley is fine. What's your name?"

Now it was her turn to ask him.

"Max Thomas Wood," he replied.

"Like a CW actor. By the way Max you have killer voice. I expect you sing outside the shower too," she teased.

"Well of course ma'am," he smirked.

"Can I ask you something else?" Mxyptlk asked.

"Yes?"

Mxyzptlk thought of asking her about her parents, and about her family who she is living with now. But he resisted the need to ask her. Maybe he should start slow and then build up the bond with her.

"Where's Mr Will Schuester's class?" he asked instead.

"Oh, so you're going to his class. Me too. C'mon let's go. This way," Marley replied.

"Lead the way blossom."

"What?"

"I have a habit of calling beautiful girls cute and fluffy names," Mxyzptlk told her.

"Oh well no one has called me by anything else other than Marley. It's kinda nice to have a nickname," Marley spoke.

"Trust me. I don't usual call girls by cute names. Well except there was that one girl that I used to call buttercup but she belongs to someone else." Mxyzptlk said.

"Who?" Marley asked curiously.

"You'll see. Someday," he mumbled.

"Huh? What'd you say?"

"Nothing, I said nothing."

Mxyzptlk couldn't stop thinking about Kara and that horrible Daxamite, Mon-El. It was him that was stopping Mxy from getting Kara. Mxy had a second chance though. Kara's doppelgänger, Marley, would be perfect for him.

How were they doppelgängers? Mxyzptlk thought to himself. Marley must've crashed on Earth from this universes Krypton.

"Oh so that's how you met Mxyzptlk," Kara commented.

"Yeah." Marley said.

"Are you hungry?" Kara asked.

"Yes I am."

*Elsewhere*

It was a sunny day in National City. Everything was so wonderful, the air, the views, and the rush of people heading to their work. But something was missing. Someone was missing.

Alex was walking towards her car. She'd been having a hard time moving on. She can't stop thinking that Maggie might've already found someone. Better than her perhaps.

Anyways, she continued walking, stopping right outside a coffee shop.

She enters the shop and stands in the line. After a few minutes, she finally reached the counter.

"Hello madam. What do you like to order today?"

"Simple black coffee would be nice."

"Okay. You seem a bit tense. Breakup?"

"Yeah, but that happened about five months ago." Alex replied.

"Well if you wanna hangout sometime, you know where to come. It isn't like this coffee shop is moving anyday soon. Oh and Miss, here's your simple black coffee."

"Thank you. By the way I'm Alex. "

"Isabella."

"Ok I gotta go. I'll be back for another coffee tomorrow."

"I might see you tomorrow then," Isabella said.

At the DEO, Winn and Brainy were at war. A huge war! Which didn't last long. Thanks to Barry.

"No! See that's not how it works! " Winn said

"Your theories are wrong. It should be like this!" Brainy exclaimed.

"NO!"

"YES!"

"NO!"

"Guys! Stop shouting, my ears are hurting." Barry said.

"Okay. Fine." both geniuses replied.

"By the way what were you two fighting about?" Barry asked.

"About how you can breach yourself into the speed force and absorb the energy that it releases," Winn said.

"That part is correct but you can also see the future, past and present," Brainy added.

"Both of you are correct. The speedforce does both of your theories. Now please stop shouting, " Barry said.

"Yeah you guys are so annoying," Mon-El said, walking up from behind.

"Sorry," both responsed.

"Hey Brainy I need to talk to you," Mon-El told him.

"Coming."

Brainy followed Mon-El out of the main area, where Winn looked as though he had tons of questions to ask Barry.

"Hmm... Barry, obviously I haven't time traveled or breaches myself to different Earths, but I really wanna know how it feels. I mean your life as a speedster, Kara's as Supergirl, and very soon Marley's gonna join the team. So what's it like to be able to do all these super cool things?" Winn asked.

"Well it's awesome. Your whole life changes and it's very hard to cope with at first, but as you start training and learning more about your powers, it gets easier. You have amazing friends to help you, you'll but amazed how much you are capable of. Travelling to different Earths is fun. You are able you see your doppelgangers and it's weird cause what you're doing here is completely the opposite there."

"Cool. I wish I had super powers."

"Hey, you help Kara and the Legion, you're a superhero to them," Barry commented

"Really?"

"Yeah. Like mine are my whole team, and my wife."

"Thanks man. But Brainy still gets on my nerves."

"It happens. On my Earth, Harry and Cisco basically kill each other. "

"Whoa."

Suddenly there was a bluish black smoke effect, and a breach opened. Mxyzptlk was back.

"Hello everyone!" Mxyzptlk greeted.

"Hi," Both Winn and Barry greeted back.

"So what happened while I was gone," Mxyzptlk asked.

"Marley has improved a lot in her training with Kara, and she needs to be tested. Oh and Mon-El wanted to talk to you for some particular reason," Winn replied.

"Thanks for the information Wine." Mxyzptlk said

"It's Winn! Why does everyone get my name wrong. It isn't that hard."

"Sorry. Thanks for the information WINN," Mxyzptlk corrected.

"Yeah whatever." Winn whispered.

"Hey, Larry Allen," Mxyzptlk said.

"Barry Allen, " Barry corrected.

"Barry. Why do you guys have names tha are so hard to pronounce?" Mxyzptlk asked.

"What?! Yours is harder. Mix-sea-peel-tlk," Barry replied

"Mxy-zpt-lk," Mxyzptlk corrected.

"Do you see that now?" Winn asked.

"Yeah but that's what you expect from a 5th dimensional creature," Mxyzptlk replied.

"Never mind," Winn said.

"Oh and have you two seen Marley?" Mxyzptlk asked.

"She went to eat. She'll be back in a few minutes," Winn said.

"They're here," he said, surprised to see them back so soon.

"I spoke to soon," Winn whispered.

"Hey guys," Kara spoke.

"Hi everyone!" Marley said.

"Hi beautiful," Mxyzptlk greeted Marley.

"Mxyzptlk I need to talk to you about something so..."

Kara pointed to the corner.

"Sure. I'll be back sweetie," Mxyzptlk told Marley.

"Mxyzptlk, I think Winn has told you that Marley has been training, and she has improved a lot," Kara pointed out.

"Yeah he did."

"Well it turns out she is capable of more than me. So I was wondering if..."

Kara stopped talking.

"What?" Mxyzptlk curiously asked.

"We should test her. I have examined her, and her powers work best when she's angry. Like burning hot angry."

"So you want me to make her angry so we can see if she's capable to go on the field with you. "

"Exactly," Kara said.

"Okay. What should I do?" Mxyzptlk asked.

"Well..."

It was 6:00 in the evening. Kara had gone to Catco to update her work. The only people left were Mxyzptlk and Marley. Now it was time for Kara's plan. Hopefully it works.

"Blossom. We need to talk," Mxyzptlk said trying to make a sad face.

"What about? " Marley asked.

"Our relationship," he replied, still keeping that sad face.

"What about our relationship?" Marley asked seriously.

"I mean... I didn't want to end it this way. I-I mean your nice and sweet but..." Mxyzptlk said, trying to contain his laughter, "But..."

"Are you breaking up with me?"

"Now I kno--" but before Mxyzptlk could complete his sentence, he was thrown out of the building by Marley.

"I hate you Kara Zor-El," Mxyzptlk muttered.

"Mxy!" Marley cried angrily.

"Oh god. Ouch! "

After a few lasers, punches and being thrown around all over the city, Mxyzptlk finally landed in front of Catco, where Kara was watching Mxyzptlk get beaten up.

For a few minutes she enjoyed it, but realised this was not going to end well.

She wanted to sneak out of Catco but Lena got to her first.

"Hey... Lena. I gotta go, my sister just called me and she's... She's having relationship problem," Kara said, trying to lie.

"I thought Alex broke up with Maggie a long time ago," Lena replied.

"Not her, " Kara said.

"You have another sister?"

"Hehe... Something like that." Kara muttered to herself.

"I didn't know you had a sister besides Alex."

"Neither did I." Kara whispered.

"Umm..."

*BANG*

"What was that?" Lena asked, looking through the window.

"Oh look at the time. Gotta go," Kara said.

"Why does she look like you, and is throwing things at that man?" Lena asked again.

"I actually don't know."

"Let me call Supergirl to prevent this misfortune from happening."

Kara finally sneaked out peacefully.

She changed, and flew over to Marley, where Mxyzptlk was almost half naked.

"Marley!"

"Marley!"

"What?!" Marley asked.

"Mxy isn't trying to break up with you." Kara said.

What!" Marley yelled, putting down the car.

"Well... We actually planned this to see your capabilities, and if you are ready to go with me," Kara said.

"What have I done?"

"Let's go home and talk," Kara said.

"Okay."

"Someone please carry me, " Mxyzptlk cried out in pain.

"C'mon," Marley said, carrying him bridal style.

After they reached Kara's apartment, Mxyzptlk got cleaned up, and they all sat on the couch in her living room.

"Who would like to start?" Marley asked.

"Me," Kara said.

"Okay. Start. "

"Okay, so I told Mxy that we need to test you, and as you see you're stronger than me. Your anger determines your strength. I also think you're ready to go with me now. "

"Really?!" Marley asked cheerfully.

"Yes," Kara replied with a smile.

"Yay!!! Max please forgive me."

"You're forgiven blossom. But..."

"But what?" Marley asked.

"You need to take me to the hair salon in the morning and fix my hair that your laser burned," Mxyzptlk said.

"Okay," Marley said laughing.

"You're lucky only your hair got burned Mxy," Kara told him.

"I know," Mxyzptlk said.

"Ouch. Don't touch it. You need to fix it somehow. I can't live with it like this. It's my precious locks, please fix it," Mxyzptlk said.

"Yes sir," Marley said playfully.

The next morning everything was back to normal. Marley couldn't wait to go with Kara and fight all the bad guys.

"Is there any crime going on, or sign of Reign?" Marley asked

"Nope, a quiet morning," Winn replied.

Marley groaned.

"Oh look, there's your first catch." Winn said.

"What is it?" Marley asked.

"There's a robber at the National City bank."

"Marley I'm coming with you. I don't want you to go crazy and burn someones hair." Kara said, interrupting.

"Good idea."

"Before you go. Marley, I present you with my latest and greatest suit that I have been working on," Winn said, showing off her new suit.

"Whoa, thanks Winn, " Marley said

The suit was white itself, with light blue strips off the shoulder, the cape was also light blue with the another side with a bit darker shade of it and the symbol was a gradient from light to dark shades of blue.

"Now I am jealous," Kara remarked.

"Shouldn't we get going?" Marley asked.

"Lead the way," Kara said.

Both of the siblings reached the National City Bank and got down to business. Marley did all the work, since Kara was just there to assist her. She concluded that Marley can go without her now.

"Well done," Kara told Marley.

"Thanks. I wouldn't be here if it weren't for you." Marley said, and Kara hugged her tight, "Kara, that is a little too tight."

"Sorry."

"Let's go back to DEO and tell everyone how well we did," Marley said.

"Okay."

Back at the DEO Marley explained everything that happened back in the bank.

"Winn what's my superhero name?" Marley asked.

"Ahh... Supergirl. Cause both of you are twins so you can't have different names." Winner explained, "I don't know, I don't usually come up with superhero names."

"Okay, but like together we're like supertwins?" Kara asked.

"Yeah," Winn confirmed.

"Yay. I'm so excited to be working with you Kara."

"Me too." Both sisters hugged, this time, Kara didn't hug Marley as tight.

After a few minutes Alex came.

"Hi guys, sorry for coming late. What happened?" Alex asked.

"Well Marley went on her first mission and succeeded. Now we have more power than Reign does," Kara replied.

"That's great," Alex remarked.

"Where were you?" Winn asked.

"Hmm... Nowhere," Alex replied.

"Don't lie to me," Winn said

"Alright! I was drinking coffee."

"With...?"

"Isabella," Alex said.

"Ha. I knew," Winn said proudly.

"Shut up," Alex ordered.

"That's great Alex. You're finally moving on," Kara said.

"Thanks for the support."

"Anytime," Kara told her.

After analyzing the environment surrounding her, she got up and went downstairs,where she found breakfast already been prepared for her. She quietly creeped over to where it lay, making sure she wasn't stepping into any kind of trap. The food was piping hot, almost like it was just made.

After eating, she went to the room she had found herself in earlier, and got changed into some casual clothes that were laying on a dresser, in the corner of the room. Just as she finished getting changed, someone knocked at her door.

Iris rushed to the door and opened it.

"Morning Rissie," Dominic greeted.

"Morning Dominic," she greeted back.

"How was your sleep?" he asked.

"Wonderful. It's like I haven't slept for ages," Iris replied.

"I hope you had all good dreams."

"Yeah. I don't know but I have a strange feeling about you. And-" she was cut off when she saw the ring on her ring finger, "Where did this come from?"

"Well... I may have slipped it on while you were sleeping," Dominic lied.

"Dominic!" Iris cried.

Iris invited Dominic inside.

*Phone rings*

"Hello?"

"Clifford where are you? I'm worried," Marlize asked, fearfully.

"Don't be," DeVoe told her.

"I've got some news. You might want to check this out yourself," she said.

"I'm coming."

"What happened D?" Iris asked.

"My job. I need to go. See you in the evening Rissie,"

"Yeah. Bye," Iris replied.

"Hello Marlize," DeVoe said.

"Clifford where were you? I thought..."

"You thought that Barry Allen had kidnapped me?" DeVoe asked.

"Something like that."

"Well good news. Mr. Allen isn't in Central City," DeVoe said.

"Then where is he?"

"He's visiting his friend on Earth-38."

"That's good, it'll keep him busy. "

"Yes it will."

"But how will Team Flash find the 3 missing metas, without Mr. Allen? And there is no current news about Iris," Marlize told him.

"Yes there's no news about her. Maybe she's hiding."

"Did she go with Barry?"

"I'm afraid not. But I'll find out... Soon." DeVoe replied.

*Earth-38*

Winn kept teasing Alex all day long, but she finally threw a punch at him. From that moment on, Winn was completely silent.

About an hour later, there was a alert about Reign and Purity destroying National City... Again.

Winn called Kara and Marley, "Calling the Supertwins."

Both sister rushed into DEO.

"What's up Winn?" Marley asked.

"Reign and Purity are destroying properties and approaching towards Catco!" Winn explained.

"We're on it," Kara said.

"We'll come as backups," Alex told her.

"Thanks. We'll meet you there."

*Two hours earlier*

"Yes Ruby, I'll be home in time for dinner. I promise I won't be late. I'm just finishing up some stuff at work. See you soon."

The cellphone rattled as it hit the desk. Sam had work to do, and hoped that no one, especially Lena would interrupt her at such a busy time.

But, she thought that too soon.

"Hey Sam, are you busy right now?" Lena asked, walking over to Sam's desk.

"Nope, not at all," she lied.

"Great, I need you to do something for me. As a friend, not as a work thing."

"Name it."

"I want to know if you want to go to this Art Gala tonight, I asked Kara, but she said that she had something on with her sister."

"With Alex?"

"That's the weird thing. No."

"I didn't realise she had another sister."

"Neither did I. And with the Art Gala thing, it's fine if you can't go."

"I'd actually love to go. But I made plans with Ruby. I've been spending a lot of extra time here, and I promised I'd be home for dinner tonight."

"That's fine, I'll just ask James instead," Lena said, putting a fakeish smile on her face, "I hope he isn't busy."

The sound of sirens rung through Sam's ears. She turned to look out the window, to see nothing there. It was a quiet time of the day, but usually you wouldn't hear sirens this high up in L. Corp.

Her eyes flashed red, as she turned from bubbly Sam, to vicious and fearless Reign.

Nothing could stop all the thoughts rushing through her mind, telling her that a worldkiller, Purity, was nearby, trying to figure out her purpose.

Reign landed in front of the woman, who was only half Purity. The other half, Julia, was trying to stay in control, slowly losing.

Purity was gaining control. Nothing could stop the world killers.

*Present time*

Winn had given the Supertwins an area of places that had been effected by the worldkillers.

Nothing could stop the wind blowing in Kara's face, as Marley trailed her, flying fast to the scene of where it happened. No one was around. It was like the whole city was empty.

So... When they flew around these areas, they were amazed to find...
