3- EARTH 1

Barry ended up in STAR LABS with Kara in his arms. He put her down. "Woah, that was cool!" she exclaimed.

"Cisco, Caitlin, this is Kara. Remember, I told you about her?"

"Oh, yeah! Sooooo cool!" said Cisco.

"So, Kara, I hear you deal with super-powered villains, too?" asked Caitlin.

"Oh, yeah," said Kara. "But, none of them looked like Barry." With that, she covered her mouth in shock. "Did I just say that? Darn, I think I just said that! Ooooooops. Well, you know, no two people look alike!" She noticed everyone was staring at her. "Um, sooooooooo..."

"Well then!" said Cisco. "I'm glad you brought a friend because guess what? I analysed the DNA of the murdered girl, and the murderer. Same DNA. Ran it through facial recognition. SAME FACES! Looks like we're dealing with a doppel-"

"Ganger, yeah." Cisco gave Barry a nasty look. "Okay, Cisco, can you figure out what powers she has? It's not like Zoom to send a teenager over to kill me."

"No, but maybe you can. There's an attack at Central City bank! Might be her! Go!"

"I'm coming, too!" said Kara.

"Race you there," answered Barry.

Barry arrived before Kara (naturally) and peeked inside the bank. There stood the same girl that was murdered (well, not the EXACT SAME, but the doppelganger) wearing a black mask and a black suit to match her black hair. The only thing that wasn't black was her pale white skin, which kind of made her look like a vampire, Barry observed. But then, to his astonishment, she touched the banker. He stood there for a second, then collapsed on to the ground. "Oh, great!" said Barry.

Kara landed next to him at this point. "I got here first," he teased. "But really, we've got problems. She touched that guy, and he just DIED! No weapon, no nothing."

"Yeah, relax, Barry. He probably had a heart attack or something. There is no such thing as the touch of death! You are ridiculous!"

To Barry's horror, she flew right in front of her. The girl reached out her hand. It got closer and closer to Kara. Barry sped toward her just as Kara fell down. He caught her before she hit the ground, just as the girl ran out the door.
