Chapter One-

I opened my eyes, the first thing I see is the ceiling of a Cyberman Warship.

"Oh crap" I stated bluntly before standing, using the wall as support as I headed towards the door.

"Okay, first find my TARDIS, next self-destruct this joint and third-"

"Graham, Ravio, head to the control deck. Cybermen just boarded."

I froze; that voice, those names. It couldn't be, they were-

"Graham, Ravio, this is Yaz. Cybermen have boarded and are on your level. Get back here as quick as you can. Yaz calling Graham and Ravio, can you hear me?"

It had to be... But that would mean...

I shook my head, right now I had to stay focused. I had to save them.

I forced my legs to stop shaking before pushing off the wall and running to where the control room most likely would be located. I slid to a stop when I saw Cyberman storming into the room.

"HEY YOU!"

The upgraded Cybermen turned and I grinned.

"Why don't you pick on someone who is much more valuable than those losers!"

One of the rusty Cybermen stalked up to me, "explain"

I smirked and spread my arms, "take a scan"

The Cyberman did and took a step back, as if surprised.

"You have the Cyberium"

"Yeah, kinda stole it from Ashad" I shrugged casually, I grinned when I saw the humans stealthily leaving the room, "that was the easy part"

"You will return the Cyberium" the Rust Cyberman demanded.

"Not this time rust bucket"

I took out my Sonic and pointed it at the Cybermen before turning it on. They screamed.

"GO!"

The humans ran and I followed.

"Where do we go?!" Yedlarmi, I think that's her name, cried.

"Hanger bay! This way" I led them like old times.

They opened the doors and raced in, there was an entire fleet of ships to steal.

"Which one of you can hotwire one of these?!"

"None of us, hotwiring was Ethan's specialty" the leader of the group called.

I bit the inside of my cheek, "fine, get in one. I'll be there soon"

"Why should we trust you?" the male, Ravio I think, asked.

I rolled my eyes and groaned a 'every time' before answering, "would you rather self-destruct this joint? No? Then listen to me!"

He took a step back before huffing and going into the ship after the others.

I pointed my Sonic to the console and checked for my TARDIS. When I received the reply of it not being detected, I activated the self-destruct.

I ran into the ship and began taking control of it. I quickly made my way to the control chair and flew the ship out of the hanger and into Cyber-Hyperspace mere seconds before the ship exploded.

I sighed and relaxed my shoulders.

"Damn, that was close" I whispered, "must be getting rusty"

"Okay spill" Yaz demanded.

"Yeah, who exactly are you?" Graham agreed, "and how did you do that?"

I looked at them before quickly looking away.

"My name is Thetra, I fought the Cybermen longer than anyone. And I am from all of your future, even the Doctors"
