Okay so I decided to make a new crossover and delete my other one. I really want to wait for Kristen Britain's new book for the Green Rider series to come out before I continue it. So here I am with a crossover with Transformers and Avengers.

P.S. Tony will most likely be acting like a kid in a candy shop so you have been warned.

Disclaimer: I sadly don't own Transformers or Avengers (goes to a corner and cries)

Also I only own the plot and the new autobots and Lennox's half sister(but she learns who her real brother is in this)

Natasha's POV

It was a normal day in Avengers Tower when JARVIS made an announcement, "Master Stark wants all Avengers to please report to the lab. Director Fury is calling." Once he stopped speaking all of the Avengers groaned and started heading towards the lab.

"We are wanting you and the other Avengers to go with our possible new allies to Diego Garcia," is what I the red-headed assassin, Natasha Romanoff, also known as Black Widow, hear as I step into the lab with my partner, Clint Barton, also known as Hawkeye, and Thor.

"Who are these possible new allies Fury?" asks Tony Stark, known as the billionaire playboy and Iron Man.

"They are known as NEST, but as to what it stands for and what they do, we don't know as of now," says the man with the eyepatch on the call.

I sigh and lean against the wall as the rest of the Avengers come in. First is Captain America himself, followed by Bruce Banner and James "Rhodey" Rhodes. "Why do you want us to go?" I ask. Fury looks at me then at every other individual in the room. "Because if they are a big threat I want you all to be the ones to stop them."

With that he ends the call and Tony turns to look at the rest of the Avengers, "So let's start packing. He said they'll be sending a plane to meet us at the airport. We got to be there in an hour." Then he walks out and we

all walk out after him and head to their floors.

An hour later they are boarding a C-17 with Captain Lennox and Master Sergeant Epps, who apparently knows Rhodey from when he was in the military. "How's it been Epps?" Rhodey asks Epps as we take off. I ignore them as I watch a man with hair about the same color of mine, bright blue eyes, walk around from the other side of the blue and red flame Peterbilt that was parked in the plane. He sits down next to Captain Lennox before he addresses us. "I am Orion Pax. One of NEST's allies." Everyone introduces themselves as a voice is heard over the intercoms.

"Everyone this is your good ole pilot speaking' here. Buckle up cause we are getting ready to land."

Tony's POV

As we get off the plane, a black GMC TopKick 6500 pickup truck and a yellow and black Camaro pull up next to the plane. Once we are off the plane Orion gets in the Peterbilt and backs it out of the plane and parks it next to the Camaro. A boy that looks about 18 gets out of the Camaro. "Hey Captain, Epps," he says then turns to us, "I'm Sam." I nod and the others give him a small wave.

"Before we show you around you all have to promise to not to tell anyone about anything you see here for the time you are here," Lennox says as he leads us to where we will be sleeping. "Of course we won't tell anyone. The people we talk to the most are here," I say using an arm to point to the others.

"Okay now Sam will show Thor and Mr. Rogers around. I'll be showing Mr. Stark, Mr. Banner, and Rhodey around. While Lennox will be showing Ms. Romanoff and Mr. Barton around," Epps says as we walk out of the barracks. "We'll be meeting back up at the hangar over there," Lennox says pointing over at a building that is larger than the others.

We split up and I hang back with Bruce while Epps and Rhodey walk in front of us while catching up. "So what do you think is so secret that no one else in the world should know?" I ask Bruce. He just shrugs and looks ahead.

"So here is where we set up a lab for you Mr. Stark and Mr. Banner," Epps says pointing at a building.

"Ok you can call me Tony and him Bruce."

"Of course and now it is time to meet up with the others."

As we head to the hangar a woman that looks sorta like me but obviously a girl walks up to us. "Hey Epps," she says.

"Hey, who dragged you out of your workshop?" he says with a small smirk on his face. She punches him hard in the shoulder. All of us besides Epps laugh. The woman finally realizes we are there and turns around and we get a good look at her. "She looks sorta like you Tony," Bruce whispers. I give him a small nod. She extends her hand out to us, "I'm Antonia Lennox but call me Toni or Ann. Lennox's little stepsister." We shake her hand and introduce ourselves. "Dr. Bruce Banner."

"Tony Stark."

She smiles, "Pleasure to meet you boys. I'll be coming with you guys to the hangar just to make sure you'll have an extra person to catch ya when y'all faint." Epps elbows her. "What? You know it is true!" she says. We just stand there confused.

"Come on boys." She turns around and heads to the hangar.

Steve's POV

We are at the entrance of the hangar when Tony, Bruce, Rhodey, Captain Lennox, Epps, and a woman come. "Hey Sam," the woman says to Sam. He gives her a small wave. "Are we goin' to wait for Will to come?" she asks no one in particular. "No need to wait sis," Lennox says as he gives her a side hug.

They lead us in and I see the Peterbilt that was on the plane, the camaro and the pickup truck that came up to the plane as we got off, and neon green, medical Hummer H2, a silver Martini Porsche 935 turbo, and a black and blue Chevy Colorado, in a semicircle.

"Before we let you meet them you need to promise again that you won't even tell Director Fury about them," Lennox says looking at all of us. "We promise but who are "them"?" asks Clint.

The woman turns to the vehicles, "Okay welp these are the autobots." All of a sudden the vehicles start moving and transforming.

When they stop there are now six bi-pedal robots standing in front of us and I'm holding Clint up after he fainted. "Hmm only one of them gave them the reaction I thought they would give," the woman says taping her finger on her chin.

The bot that was the Peterbilt bends down and looks at us, "I am Optimus Prime leader of the autobots. This is our weapon specialist, Ironhide, our resident medical officer Ratchet, head of special operations Jazz, our scout Bumblebee, and our resident engineer Meltclaw." He pointed to all of them as he spoke.
