Note: so, I said this on Facebook but for those who are not there I will repeat it here, for certain reasons I can't update on Friday, but I am not going to back out of my promise of updating twice a week. My second update this week will be on Wednesday.

Chapter 3: A Familiar Face

"Guys, that building's destabilizing," Cisco said over the coms as Kara and Barry were heading towards the mutant. "You might want to hurry up and get there before more deaths are on this woman."

"I'll go into the building. You stop the mutant," Kara instructed Barry, since she couldn't be hurt by the falling debris.

"Got it," Barry said as the two were close.

Kara went into the building, not even stopping as she started taking people out at super speed. She couldn't stop this building from collapsing, but she could get everyone out and safe – fast. Luckily it wasn't a big building there weren't too many people inside, so everyone was out by the time the building finally collapsed.

Barry on the other hand had attacked the mutant, stopping the scream and making the mutant turn around so he could look at her. "Loud voice –" Barry started with a smirk, ready to make a further comment but paused as he looked at the mutant. She seemed unusual and the outfit she was wearing was more goth than Barry ever knew her to wear, but Barry knew that face. "…Laurel?" Barry asked, not believing it. He had just been toasting with Oliver yesterday on memory of Laurel; about fighting in her honor, now she was standing there in front of Barry, but so different from the one he knew.

"Laurel Lance is dead," the Laurel lookalike said with a smirk. "Well, at least on this Earth from what gather. You can call me Black Siren." Laurel let out a scream, right at Barry that knocked him backwards. His ears were ringing. That was louder and stronger than anything Silver Banshee had done on Karry Universe all that time ago. This Black Siren was clearly stronger than her.

Barry got up, undeterred, and ran around Laurel, tossing a lightning bolt. Laurel went to dodge but got hit on the arm, knocking her over. She got up, rubbing her arm. "Not bad kid," Laurel said. "My turn." She let out another wail, knocking Barry over again.

Laurel went to get closer but felt an arm from behind her and she was tossed backward. Standing, she was face to face with Lady Power and she had to smirk at this face. "Sorry, but I don't take kindly to my boy being tossed around," Kara said with a smirk of her own. "And you don't want on my bad side."

Laurel chuckled a very low chuckle. "Oh heroes," she said, nearly rubbing her hands together. "So much fun. I have missed this. I was starting to think those two losers in the robot suits was all this Earth had to offer. Where would the fun be in people I could take down so easily? But you two…" Barry had joined Kara facing Laurel now, "you two are worth the deal."

"Deal?" Barry asked, confused.

"My world had very few heroes. Oh, they were good, but not many. No big numbers. We realized we could out number them, take them down, and we did. Killed every last one of them and took over. Well, nearly every one. Any wannabes were too scared and the vigilantes were easy to break. We thought it would be all fun and games, but well without the heroes it was boring. No one challenged us. No one cared if we stole or killed or did whatever we wanted. Heroes make being a bad guy fun, so when he said I could go to a world where I could have fun again I was all for it. Chaos in a new world. New heroes to fight. All I had to do was kill one person. He's harder to find than I thought though."

"Well this is over," Kara said, bored with the monologue, letting out a freeze breath which Laurel countered with a cry of her own – the sheer magnitude of the cry destabilizing the icicles from Kara's breath before they did harm to Black Siren. As the two were at it, Barry ran to get behind Laurel, but Laurel seemed to sense him. Cutting off the wail, she ducked under and tossed Barry right into Kara's still-going freeze breath.

Kara stopped, going to check on her boyfriend as a wail hit into them making them both fly backward. Kara checked her ears. They were bleeding. "Your vitals are going nuts!" Caitlin said worriedly in her coms.

"You know I killed my earths Supergirl?" Laurel now mocked. "Although she wasn't blonde. Well Supergirl and Superman were easily taken down – they were the only heroes with powers, at least those brave enough to face us." Laurel seemed pleased as she was talking. "Your super-powered sister did get away though. Never found where she went. Maybe she's dead now too."

"I don't have a sister," Kara said, as they were hit with another cry, Siren clearly enjoying herself.

"You need to get out of there now," Caitlin said as she monitored their vitals. The two were not winning this fight.

Kara look up and used her heat vision. "You missed," Laurel said, since the heat vision went right over her.

"No. I didn't," Kara said making Laurel raise an eyebrow but stopped as a street lamp fell on top of her, distracting her. "Out of here, now." Kara took to the air, taking Barry with her.

"I could have run," Barry mumbled but did not complain. He had taken more hits than Kara did after all and was still recovering from the freeze breath.

Laurel got up, shaking broken glass off her from the light. She was bleeding and was a bit beat up, but she was in one piece. She chuckled as she watched the two leave. "Oh, you two are good," Laurel said, respecting the creative way they had gotten away. She knew next time she saw them they would be more prepared to face her than this time, and she looked forward to the challenge.

Barry and Kara sat in the lab. Caitlin had looked over the two of them but they were already healing – Kara under some yellow sun lamps too. "How did a wail take you down so easily?" Joe asked Kara and everyone looked at her, equally curious. They were used to her being indestructible. Very little got through her Kryptonian powers.

"I have super hearing," Kara stated the obvious with a shrug.

"Makes a wail like that even more effective," Caitlin stated, figuring it out as the two rubbed their ears. Barry had already gotten to work on the earplugs he had used against Silver Banshee when on that Karry Universe, not even sure why he hadn't made them before, knowing their enemy was a screamer. He hadn't been thinking, and he was cursing at himself for it.

Cisco on the other hand was working on something else. "Harry, help me here," Cisco said. "I think I can make a collar of sorts that can stop this Siren's powers."

Harry was looking over Cisco's notes and was nodding to himself. "Very good Ramone, although I can see how to make them better," Harry said, starting to write down his own improvements.

"Who would bring Laurel Lance's doppelgänger here? With the partial-destruction of the multiverse, I thought we would need a vibe portal to get on and off this world now? I haven't been able to Earth jump again. And, obviously, Cisco did not bring Laurel here," Barry asked after he was done with the ear plugs. "And who does this person want to kill on our world?"

"Is it someone from this world?" Iris asked. She had been silent since the two had got back. No longer feeling part of the team, but wanting to make sure everyone got out alright this time. "I mean, someone else but Cisco could have the same power. There were two weather wizards after all."

"It's not so easy jumping worlds," Cisco pointed out. "I had problems getting us off Karry."

"Yeah, Vibe Junior," Kara said with a smirk as Cisco made a face at that name. It seemed Kara had found a nickname for him that she liked, just like she liked using 'Stalker' for Barry. And just like Barry's nickname, his new one was so not going away anytime soon. Iris rolled her eyes at this childish nickname wondering what Barry saw in this girl.

"We'll have to capture Laurel and find out," Barry said, still distracted.

-Mutant Earth-

Black Siren was in a warehouse she had taken for her own, planning her next target and wondering how long before Flash and this Earth's 'Supergirl' would be in coming to take her down again. Although Laurel had found out this Earth did not call her Supergirl, but instead used the name 'Lady Power'. There was also no word on Superman. She would have to find him. He had been a challenge. Oh, she was going to have so much fun with them…

That was when there was a blue portal opened beside her and a man stepped out of it. He wore no goggles like the Vibes did or gloves, he had long hair and a little bit of a mustache going for him. "What are you doing?" He asked seeming annoyed at the woman.

"Plotting," Laurel said airily, not even looking up at the man. "So far, I have been having fun just destroying and causing chaos, but I want something more. I was deciding if I wanted to break a bank or a jewelry store." Laurel finally looked up at the man with a smirk. "You know, a girl likes having pretty things, even if she is a villain."

"You have not kept our bargain," the man said angrily, "I brought you here, and you agreed to kill him for me."

"Look, I took down his apartment building, his favorite comic book shop, his favorite restaurant. He's not an easy nerd to find," Laurel sighed, rolling her eyes. "What did this guy ever do to you anyway? I don't even think this is your Earth."

"The reasons why I want him dead are none of your business," the man snapped. "I hired you to do a job, I kept my end now keep yours. Kill Francisco Ramone!"

"I think he goes by Cisco," Laurel shrugged as the man glared at her, clearly not amused by the nickname or her lack of fire to take him down. "Fine. Any idea where he is?"

"He'll be at STAR labs," the man said.

"STAR labs…? Not an easy building to take down if it's anything like my Earth's," Laurel said already thinking this over. "That place is reinforced and has advanced technology. STAR Labs was one of the last places to continue to fight after all the heroes were gone."

"Well, figure it out then." The man said, turning around, but stopped. He didn't turn back around though, but he didn't leave either. "Oh, and he works with your little heroes there. They won't want him dead." Laurel raised an eyebrow and smiled. "You might find fun in that."

"Definitely," Laurel said as a blue portal appeared and the man was gone.

Post Chapter Note 1: I hoped you liked this.

Post Chapter Note 2: To be honest I am surprised not more people guessed Laurel Lance/Black Siren as the wailer. I think I managed to surprise almost all of you here.

PLEASE REVIEW.

Karry Master OUT!
