Chapter 1.

Chase's POV.

Mr. Davenport and I were in the lab, working on a new invention together, when the mission alert went off, Adam and Bree running down the stairs. Leo normally would've been right behind them, but he was at summer camp. Mr. Davenport started looking at the cyber desk.

"Oh no." He sighed.

"What is it?" My sister asked.

"In Maine. Some crazy guy is killing innocent civilians."

I looked at the picture and smirked.

"What's with the getup?" I asked as I referred to his clothes, which looked like a pirate's.

"Now you know why I called him crazy, Chase. Not only is he killing innocents, but he dresses like that." Mr. Davenport explained.

"He probably didn't get his Halloween candy." Bree laughed.

"Seriously guys, get dressed in your clothes and get to Maine. I'll meet you there." Our father explained.

We nodded as we got into our capsules and changed into our mission suits before grabbing onto Bree's arms, and she sped us to Maine. As soon as we got there, we saw him.

"Who are you?!" I demanded as we all got into fighting positions.

The man turned around and smirked before answering.

"Well, most people call me Hook. Captain Hook. But if you want a name, Killain will do."

I burst out laughing and said.

"I don't know whether to take him to jail or put him in a mental facility."

Making "Captain Hook" glare at me as he suddenly lunged.

I heard screams, but the main thing I felt was something sharp get stabbed into my side. Then after a few seconds, my vision blurred and the room started spinning. I then fell into unconsciousness, hoping my siblings would stop Hook.

Bree's POV.

I watched as Killain plunged his hook into my brother's side. I wouldn't stand for this.

"Yahhhhhhh!" I yelled as I tackled him and hit him in the face multiple times with my super speed before knocking him out.

Wincing as I pulled my gloves off, I found out my knuckles were bloody and bruised. I pulled them back on and tied him up, just as Adam yelled my name. I ran over to find out he had turned Chase on his side and pulled the top of his mission suit up. Then I saw something yellow oozing out of it. Feeling sick immediately, I asked.

"What the heck is that?"

"Why are you asking me?" My brother replied.

I shrugged in agreement and turned on my comm set.

"Mr. Davenport!"

"Bree, did you get the man?"

"Yeah, we got him, but he hurt Chase badly. His side is bloody and there is something yellow oozing out of it."

"Alright, I'll be there in a few minutes. Is he unconscious?"

"Yeah he is. He also looks very pale and in a lot of pain."

"Ok, I'm coming in." My father sighed as he turned off his comm set.

I turned mine off and turned around to see our not so fit father run in, kneeling down beside Chase.

"It's worse then I thought...we're gonna have to get him some help somewhere else." He explained after examining him for awhile.

"Where?" I asked.

My father answered me immediately.

"Storybrooke."

Yay! So a few things we need to go over.

This takes place in season 2 of Once upon a time after the episode where Cora dies.

And season 2 of Lab Rats right after they they find out Douglas is their father.

This is AU because of a few reasons, but one of the main ones is because I need Belle to remember who she is at this time.

Call her Angie she likes that is my beta reader/editor.

I want/need someone to make a trailer for this on Youtube if at all possible.

This is the FIRST lab rats/once upon a time crossover!

Over and out.

Susz.
