Chapter 1: We're not in Kansas anymore.

Hello there! I don't own Star Trek, or anything else mentioned here apart from the plot.

Summary: The reboot version of MirrorMirror. After a transporter malfunction, Carol Marcus finds herself in an universe resembling her own but also vastly different. Keep in mind that the universe is not the one with the ISS Enterprise, this one is different in other ways which you will have to read to find out. And it's only Carol that goes. Also, Christine Chapel and Janice Rand exist in this fanfic, in both universes and their roles are the same from the Original Series. Furthermore, this is Pre-Beyond, because Carol wasn't in that one. Carol / Jim, and maybe Spock / Uhura.

Carol had been called down to the planet by the Mr. Spock to aid the landing party, even though she wasn't originally on it. The Captain also was inclined to go down but he was still recuperating from another mission and Dr. Mccoy was adamant that the Captain didn't leave the ship because 'Damn it Jim! Overtime you leave the ship, you return looking like a damn blobfish!' and so, the Captain was reluctantly staying behind.

"Scotty, are you sure the transporter's gonna work with the ion storm near by?" Jim had come down to the transporter room to see that everything was in order before Carol went down, because he was the captain and he worried about all his crew.

"Don't ya worry, Captain! Storm's far enough not to mess with ma controls."

"Very well." Jim turned towards her, "Be careful down there, Doctor."

Carol nodded, "Of course, Captain. I don't think we'll be down there for long now."

"Good. Mr. Scott?"

"Ready here, Captain."

He smiled at Carol, and she smiled back. Ignoring the feeling in his stomach, Jim turned to the scotsman. "Energize"

Just then, something hit the ship and rattled them all. Kirk fell to the ground and hit his head rather hard, quickly he got up again ignoring the dizziness he felt and shouted, "What the Hell was that?"

"I don't know, Captain!" Scotty was messing with the controls. Carol seemed to be stuck in the transporter, glimmering and half transparent.

"Carol, get off the transporter!" Kirk yelled, but she didn't seem to hear. In fact, she was completely frozen but her figure kept flickering.

He was about to jump on the platform to get her, when yelled for him to stop, something about his safety and the dangers that could happen.

Then, Carol stopped flickering. She disappeared completely from the transporter platform.

"Scotty, is she on the planet surface?"

"Checking right now, sir."

Scotty lifted his head in alarm and shock his head, "No, sir. She's not there."

Then where is she? Jim turned to look at the platform where his friend was moments ago, praying to whomever was listening that she was okay.

Dr. Marcus opened her eyes, she had appeared on a very similar platform, only this one was on the opposite side of the room as the one she was used to. She felt rattled, and also confused for the planet they were studying had no life forms, especially not any with transporter capabilities.

She frowned. The landing party was nowhere to be seen, and neither was the Captain or . The only person in the room apart from her was an Ensign she recognized from the science labs, Ensign Espinoza. Only he was wearing red, not blue; and the uniform design was different from the ones used on the Enterprise. The trousers were dark gray and the shirt was a deep red with no patterns and it seemed to be made of a sturdier material than the ones they currently had, the opening for the head was wide leaving the neck and part of the collarbone exposed.

Espinoza looked at her seemingly perplexed, "Carol?" He asked, "What the Hell happened to you?"

And then Carol knew, she wasn't on the Enterprise anymore.
