AN:This is my first attempt at a soulmate fic. I'm using the "the world has no color until you meet your soulmate" version.
"What's going on?" Felicity asked as she, Iris, and Caitlin went into the breach room. Cisco and Barry gave her guilty looks as they stepped back from a large machine. It was humming and had clearly just been turned on.
"We were just...seeing if we could open a breach." Cisco said. He looked away when he met Caitlin's eyes.
"We have a theory." Barry continued. "That we could potentially open a breach to all the earths simultaneously."
"And then we could just pick one and pop over." Cisco finished. Felicity and Caitlin shot each other incredulous looks. Iris facepalmed.
"For people who claim to be such fans of sci-fi you guys are idiots." Felicity grumbled.
"You don't see how this could go wrong?" Iris asked. "What gives us the right to go from earth to earth?"
"But we wouldn't be-" Cisco began.
"You could accidentally change countless people's lives." Felicity cut him off. "Oh yeah." She glared as Barry scoffed. "What happens if you're dead on the earth that you visit? What happens if you accidentally hurt someone? You get to leave; the people you visit are stuck with the consequences of your actions."
The boys were about to protest when Caitlin shut them down with one silent murmur of, "It's exactly the thinking that created Zoom."
They frowned, looking at the machine. Felicity put her hand on Caitlin's shoulder while Iris glared at them.
"Shut it down." She ordered. The boys looked at each other and sighed.
"Fine." Barry muttered, looking annoyed. He walked over to the machine and began flipping switches and pressing buttons. It shuddered and sparked. Suddenly a breach opened and began pulling them all towards it. Iris was the closest, but Barry pulled her out of the way. Cisco pushed Caitlin down. Felicity lost her balance and fell. Sliding through the breach she caught sight of Barry running towards her. She reached out her hand, but the breach closed too fast.
Barry ran at the breach but the second Felicity went through, it closed and he slammed into the wall. They all stared in horror at the empty place where she'd disappeared.
"Felicity." Cisco said.
"Find where she went." Barry shouted. Cisco nodded, running to the computers.
"This is bad."
"What?" Iris asked.
"Well according to this." Cisco said. "I can't trace it...our theory worked a little too well." He gulped. "I've been able to narrow down her location to...three thousand different parallel earths."
Barry covered his mouth, looking at the breach machine. Iris shut her eyes, turning away. Caitlin's eyes were wide and she went completely pale. Cisco was close to tears.
Felicity fell, surrounded by the blue walls of the breach. Around her different worlds flashed by. She caught glimpses of many strange things in those Earths. A space ship. A man wearing a golden helmet. What looked like another version of Oliver with a feathered hat and goatee. A man in blue and red with a giant S on his chest flying through the skies. Then a breach opened up in front of her. She screamed as she fell, landing in a dark alley. Standing, she wiped her hands on her dress and looked around. It was dark...too dark. Something was really off. Looking around her, she walked out of the alley and began her way down the sidewalk. She shivered. It was cold and rainy in whatever city this was. It sure didn't look like Central, though she couldn't know what this version of Central would look like. There was a garbage can ahead with newspapers in it. She walked over and gingerly fished a paper out. She flattened it out.
"Gotham Gazette." She read. The article was about a confrontation between someone named 'the Riddler' and Batman." She took the paper. It could give her some valuable information. Looking around, she realized something else. This earth, whichever one it was, was in black and white. There was no color. Her dress, that she knew to be purple, was now a faded gray. Her nails were no longer red, but black. Everything around her was faded, muted and various shades of gray and black.
"You lost, blondie?"
The voice came from behind her. She spun around to see a man leaning against the street lamp about 5 feet away from her. He was tall with dark hair that had a white streak, running through it. She frowned and backed up.
"No. I know exactly where I'm going."
"Really?" He smirked. "Even after falling through that wormhole?" Her eyes widened. He nodded. "Oh yeah, I saw it."
Felicity shut her eyes, her legs shaking. "Are you going to kill me? If so, please just do it quick. I just fell through a breach into this dark and cold and creepy place that has no color and-"
"I'm not going to kill you." The man said. "I don't do that anymore."
Felicity gaped at him. "Anymore?" She said slowly, backing away. He watched her, not moving but watching her.
"I only killed criminals and there were...extenuating circumstances." He frowned. "It's a long story."
Felicity looked at him. She was usually good at reading people and her gut told her he wasn't a threat. He looked regretful. "I'm Felicity." she said. He looked at her.
"Jason." He replied. "You...you mentioned the world was black and white?"
Felicity nodded. "Ever since I got here." She said. "Is that normal?"
A look of sadness crossed his features, but he nodded. "Yeah." He murmured. "You can only see color when you meet your soulmate."
"Soulmate?" Felicity asked. "That's a thing?"
He nodded. "You can stay with me." He said, motioning for her to follow.
Bruce Wayne sat in the Batcave when an alarm went off. Frowning he looked at his computer. There was bizarre energy reading...in crime alley. He jumped to his feet. Grabbing the Batsuit, he turned on his com. "Batman to Watchtower."
"Go ahead, Batman." Martian Manhunter replied.
"I need Zatanna for something.' Bruce glanced at the computer.
"I'll send her your way."
Bruce nodded, hacking the camera closest to the alley. Rewinding the tape, he watched as a strange light bubble formed in the alley. Then it seemed to tear open and a woman fell out. She was young and scared. He watched as she looked around, her eyes were wide. She walked down the street, shivering, rubbing her hands on her shoulders. She didn't seem threatening, but he couldn't be sure. She turned out of the alley and walked out, looking around her. She grabbed a newspaper from a trash can. Smart, that way she'd know the date and where she was. Then another figure entered the view of the camera and Bruce gripped the seat as he recognized him.
Zatanna entered cave. "Where's the fire?" She asked.
"Someone seems to have tumbled into our world." He looked at her. "I need you to track her."
"Her?" Zatanna said, smirking. "Bruce, there are easier ways to get a date."
"Zatanna this isn't a joke." He looked back at the screen. The woman was leaving. "Red Hood has her."
