"Keerah!" Cat Grant screeched from her desk.

Winn watched as Cat came out to dramatically look at Kara's empty desk. Cat then scanned the floor to look for her assistant. The entire staff at the executive floor of CatCo Worldwide Media ducked their heads to avoid being given whatever demoralizing task she had in store. She locked eyes with Winn and approached him as he desperately tried to think of some excuse for his friend's hundredth absence. You would think he would have gotten more skilled at coming up with them, but Cat was so cold hearted that she only found one thing to be excusable; and there were literally only so many times he could say Kara was cramping from that-time-of-the-month.

"Winn, where's Keerah?" Cat demanded with a piercing gaze.

"Well, you see...she text me this morning that-" Winn stammered.

"And don't tell me she's cramping again for the third time this month."

"Uh...car trouble?"

"That's preposterous! With what I pay her she could never afford a car. You know what, I don't care. If she's not here in the next five minutes it won't matter anyways."

"Why is that?"

"Because she will no longer have a job. I thought my indignant tone made that implication very clear."

Cat went back into her office without another word. Winn let out a low groan as he picked up his phone and called Kara.

"Hi! You've reached Kara Danvers. Sorry I can't come to the phone right now, but if you leave me a message I'll get back to you as soon as I can. [BEEP!]"

"Kara, where are you?" he whispered. "Cat is angry– well, angrier than usual– that you're not here yet. Just get here as you get this message...I hope you're okay."

Winn got up from from his desk and made his way towards Jimmy's office to see if maybe he had heard from her today. He took the long route along the windows so he could include a stop at the break room to pour himself his 2nd cup of coffee. He yawned as he took in the birds' eye view of National City, and then his jaw snapped shut in surprise as he witnessed a streak of blue lightning race along the expressway.

What's The Flash doing here? Did Barry get himself into trouble again? Winn thought.

That's when he heard the sonic boom as Kara – or rather Supergirl – flew into the air. Only from what Winn could see it wasn't a controlled flight. Almost like she had been knocked into the air by The Flash.

He clenched his jaw as he saw Supergirl smash into the tenth floor of one of the surrounding skyscrapers. Winn took off running for the elevators and dialed the DEO.

This can't be good.

"I don't have time for this," Kara groaned as looked up at the time on the bank's digital billboard sign. It was 8:13am – and a cool 72 degrees.

"What's the matter Superfreak? Got a date or something?" Livewire bantered.

"No, I'm late for- never mind that. How do you keep getting out, anyways?"

"What can I say? I guess you really can't keep lightning in a bottle!"

Livewire cast a bolt of lightning at the heroine. Supergirl flew into the air to avoid the attack and used her super breath to knock her opponent closer to the fire hydrant at the edge of the block. Supergirl then used heat vision to knock off the top of the hydrant and sent a geyser of water into the air, soaking the villain.

"Not again!" Livewire crowed.

The surrounding crowd applauded Supergirl's rapid victory just as the police rolled up in time to slap handcuffs on Livewire.

"You got it from here?" Kara asked one of the officers.

"Yeah, thanks again Supergirl," the officer replied.

Good, because I need to get to work before Cat fires me, Kara thought.

Just as she turned to the direction of CatCo she saw a flicker of light, followed by the familiar whoosh of a speedster.

"Why hello there Flash," Supergirl smiled as she turned back around, and then gasped in horror.

Rather than seeing the Scarlet Speedster, she instead saw a horrific figure clad in a black suit with sparks of blue lightning all over his body.

"Sorry. The Flash isn't available," the figure spoke rather ghastly.

"Who are you?" Kara demanded.

"I'm this Earth's new ruler. But for now, you can call me Zoom."

"You're from another Earth, aren't you..."

"I see you're familiar with the multiverse."

"Yeah. Well, since you're new in town let me explain something. I'm Supergirl, and I'm the protector of this city. Why don't you tell me how you got here so I can send you back the way you came."

"I don't have to explain myself to you."

There was a sudden flash of light and then he was gone.

He's faster than Barry. Way faster.

The policemen suddenly dropped and Kara noticed Livewire was gone. Either she ran, or Zoom took her; however, the injured police officers where her first priority. Kara knelt down to check the officers, and grimaced at how contorted their necks were.

"Oh no!" Kara cried.

She sped to each of the officers and confirmed the same thing. They were all dead.

Kara tapped her earpiece to activate her comms.

"Alex, are you there?" Kara uttered.

"Yeah, Kara. What's going on?" Alex replied over the radio.

"I need you to get Hank out here. There's a speedster running loose in the city."

"Did what's his name get himself stuck out here again?"

"No, this guy...Zoom...He killed...Just tell Hank to get out here now."

"Oh God...Okay, we'll be right out-"

"No! You stay put! He's different than anything we've faced before."

"But I can help."

"Not this time."

Supergirl turned off the comms and flew into the air. She focused her attention on any sonic booms or cries for help. There were screams happening all over the city, with police band filled with reports of officers down. They were all happening so fast, it seemed like it was coming from everywhere at once.

Finally, she spotted the blue lightning streak cutting across the central park towards a pair of police officers at a hot dog stand. She swooped down and rammed Zoom with her shoulder, knocking him off course.

"You again," Zoom spat. "I was going to save you for last. But I guess you leave me no choice."

"You're not going to hurt anyone else!" Kara roared.

"Is that so?"

Zoom then charged directly for Supergirl, and she had difficulty keeping track of the distance. She planted her feet into the ground, ready to use her strength and invulnerability to act as a literal roadblock for the sinister speedster. Zoom was directly in front of her in what felt no time at all.

Instead of feeling a sudden impact, she felt an odd sensation; like a strong gust of wind not only over her body, but through her body. Then, she didn't see Zoom at all anymore.

"What the-"

A sudden scream, and she turned and saw Zoom was holding one of the police officers up by the neck in one hand, and his hand was through the chest of the other. Kara screamed in protest as Zoom snapped the neck of the officer he held and casted both of them aside. Zoom then used his blood soaked hand to remove his mask to reveal what Kara would have considered to be a rather handsome man under different circumstances.

"Why did you do that? This fight is between you and me!" Kara asked.

"You heroes never learn do you," Hunter Zolomon scoffed. "There is no such thing as fair. Only the ones in power can set the rules; and that's no longer you."

Another flash of light and Zoom was gone once again. But how? She was Supergirl, the fastest person on the planet, next to her cousin. How could she be so powerless to stop him?

No, don't let him get to you, Kara thought. Just stay focused, and you'll find some way to beat him. You always do.

Supergirl flew once again and scanned the city. From the small interactions she had with Zoom, she could tell that he was arrogant enough to stay in plain sight. Or maybe it was that he was sadistic enough to make sure she could see his acts of terrorism.

There! On the expressway! She could just barely make out the streak of lightning. Supergirl flew down to the ground as Zoom charged at her directly once again. She waited for him to phase through her and so she could then quickly turn around and use her heat vision while his back was turned.

BAM!

Supergirl went flying through the air, too stunned to be able to stop herself.

CRASH!

Supergirl groaned as she slowly got to her feet, broken glass sliding off her cape. She was in some sort of office building, most of the occupants were running away while a small fraction rushed up to check on her.

"Are you okay, Supergirl?" a young woman asked.

"Yes, I'll be okay. Is anyone injured?"

"No, thankfully!" the young woman replied. "We were all gathered at the corner conference room to celebrate a coworker's birthday when you crashed the party. No pun intended."

"Tell everyone to stay inside the building. Preferably away from the windows. It's not safe outside right now."

"Sure thing. Are you sure you're okay?"

"Yes, thank you."

The two women waved goodbye to each other and Supergirl flew off once again. As she gained altitude she was joined by Hank Henshaw– or rather, the martian J'onn J'onzz.

"I'm so glad to see you!" Kara exclaimed.

"What is going on?" J'onn inquired.

"There's some crazy speedster running around. We need to find some way to trip him up and stop him for good."

"Can't we just corner him?"

"He can somehow move through solid objects. I don't know what we can do to stop him short of..."

"I think I might have a way. I just need to get in front of him," J'onn proposed.

"I don't think that'll be a problem," Kara shot back.

The two heroes land in front of the streak of blue lightning as Zoom tore through the city towards the police headquarters. Supergirl then leapt forward with her own speed, and pounded the ground with her strength to make Zoom lose his footing. Zoom easily leapt across the large crater her fists had created, but this meant that he was no longer accelerating. She used her super breath, but instead of blowing she inhaled deeply since he had already gone past her.

Since Zoom was still in the air, he was pulled back and lost his footing as he landed. He stumbled for just a second, but that was all the time J'onn needed. The martian grabbed onto Zoom and looked him in the eye, and the villain suddenly collapsed.

"Finally!" Kara exhaled in relief. "What exactly did you do to him anyways?"

"I used my psychic abilities to convince his mind that he was asleep, which rendered him unconscious," J'onn explained.

"When you say psychic abilities...does that mean you can do, like, mind reading too?"

"Yes, but don't worry. It doesn't work on Kryptonians."

"Oh good! But that's not what I had in mind. I guess that means you really can't read my mind, ha!"

"What exactly did you have in mind, Kara," J'onn sighed as he gave her an exasperated look.

"What I meant was, can you read his mind to find out why he is here and how he ended up on this Earth?"

"Do you mean that in some kind of existential sense?"

"No, more like a multiple universes kind of sense."

J'onn decided not to ask anything further and knelt down to place his hands on Zoom's head. He closed his eyes, however Kara was able to see them moving rapidly underneath the eyelids. J'onn then opened his eyes and stood up to face Kara.

"It looks like he really is from another Earth," J'onn began. "He was trying to steal speed from The Flash of a different Earth, someone named Barry Allen. But somehow, he was thrown violently out of that Earth and into some kind of breach, almost as if time and space itself had cast him out. He has no idea how he ended up here or what could have caused such an anomaly."

"You sure it was Barry Allen that he was fighting?" Kara entreated.

"Yes. His thoughts were consumed by his goal of stealing Mr. Allen's speed; as if his life depended on it."

"Stay close to him and make sure he remains unconscious. As much as I hate the idea of keeping someone comatose, he's just too dangerous to even chance it. Did the DEO ever install one of those cells Barry had designed for the metahumans on his Earth?"

"I'll make sure our guest is put in there right away."

Both of them took flight, each holding on to a limb of their prisoner to ensure he could not escape.

I wonder what is going on back on Earth-1? Kara wondered.
