Unexpected Help

Transformers and Thor Crossover.

Parings: Sam X Mikaela Tia (OC) X Optimus Prime

Disclaimer: I don't own anything from Transformers that all Michael Bay and I don't own Thor that's all Marvel. I do own Tai Bello.

Tia was slowly coming round when the trio was transferred from the vehicle convoy onto a helicopter, with three other passengers. She groaned in pain as she was jarred and jolted as the helicopter took off and started fly across US airspace.

One of the other passengers, the only female, suddenly looks at her with worry in her eyes as she asks the trio "What did they get you for?"

Sam glances at Tia, who is fully conscience now and is in little pain, and when she nods he replies to the blond, "Bought a car, which turned into a giant robot. Who knew?"

At the looks of disbelief on the others faces Tia laughs and says "Well I met, said giant robot as well as being the only Demi-God Daughter of Thor."

"Thor as in the Asgardian God of Thunder. Oh and I'm Glenn." An excited man says.

Tia and the blond share a glance before chuckling.

"I'm Maggie and this is John Keller, Sectary of Defence." Maggie says as John nods.

"Nice to meet you Maggie, Sir. I'm Tia Bello, this is Sam Witwicky and this is Mikaela Banes. And to answer your question Glenn, yes that Thor."

Mikaela and Sam nod as the other passengers look at them and all of them fall into a semi comforting silence, when Tia looks out of the window and feels a strange and powerful presence heading towards them.

But what Tia didn't know was that, it was getting closer to them they were heading towards it and the Autobots where unknowingly right behind her.

With Optimus and the Autobots they stop outside an old museum and the transform after scanning the area for Decepticons and humans alike. When Optimus transformed he had Mjolnir and the glasses carefully held in is hand.

As the other Autobots transformed, Optimus looks sadly at Mjolnir then as a determined look enters his optics, he looks at the old scratched glasses and takes an intake of breath.

"Please, let this work," He murmurs as his Autobots surround him.

Jazz, who was walking and flipping on the roof of the museum, says to his commander "Fire it, Optimus."

Two blue lasers shoot from Optimus's eyes, just like when he was showing the trio of humans the hologram of Megatron and the war, and hit both lenses of the glasses. A spectrum of light refracts from the glasses and it forms an almost cube like diagram of the Earth and in one part of the land masses shown in the pictures, was a steady beating dot.

"The coordinates from the glasses pinpoint the All Sparks location to be 250 miles from here."

With that said Optimus ends the lasers as Ratchet turns slightly and starts to sniff the air.

"I sense the Decepticons are getting ready to mobilise."

Ironhide turns the same way and mutters the group "They must know it's here as well."

But Jazz, as stubborn as always, shouts "What about Bumblebee? We can't just leave him to die and become some human experiment. And what about Tia, you heard her story we can't let it happen again."

Optimus argues with a heavy spark "They'll die in vain if we don't complete our mission. Bumblebee is a brave soldier; this is what he would want… And Tia can protect herself" 'I Hope.'

Ironhide walks up beside his leader and askes "why do we fight to protect the humans. There are a violent and primitive race; the young femme is proof of this."

Optimus flinches at the mention of what happen to Tia but replies "Where we so different? They're a young species, who have much to learn, but I have seen goodness in them." 'Tia you are proof of this as well.' "Freedom is the right of all sentient beings. There is only one way for use to win this war and you all know what it is. We must destroy the cube, but if all else fails I will united the cube with my spark."

Ratchet turns quickly to his Commander "That's suicide, the Cube is raw power it will destroy all three of you."

Optimus turn to his CMO "A necessary sacrifice to bring peace to this planet, we can't let the humans pay for our mistakes. And three Ratchet?"

"Yes, the All Spark, You and Tia."

Pain flashes across Optimus's optics "Tia would understand. It has been an honour serving with you all. Autobots Roll Out!"

Jazz spins and shouts "We're rolling!" as the Autobots follow the Prime in the direction of the Cube.

Tia slow climbed out of an SUV, following Sam and Mikaela as they walked to the edge of Hoover Dam to look down it. But more S-7 agents herded us to the main builder and just as they were about to pass some Army Rangers, Simmons walking in front of them with Luke standing like a loyal dog behind him.

Tia snarls at them and storms past them and shouts over her shoulder "You should be careful of whose company you keep Simmons. Once a traitor always on isn't that right Luke."

She ignores the glare at her back as she dismisses the conversation between Sam and Simmons as she walks to the Rangers, and stands in front of their Captain.

"Tia Bello Demi-God daughter of Thor." She says while holding out her hand.

"W…Will Lennox, nice to meet you and thank you."

The rest of the soldiers look at the woman in awe as she looks at the Captain with a confused look on her face.

Will seeing this says "On the 5th December last year you saved a woman and her children from a drunken driver. That was my wife Sarah and daughter Annabelle."

At this Tia smiles and pats his shoulder with a smile on her face, but the moment is ruined as a spell goes flying and hits Tia's already injured back and makes her fly into the wall pf the builder and she creates a hole in the wall.

With a pained groan Tia slowly crawls out of the hole to see Luke disappear in a flash of green smoke. The Agents were panicking slightly as she stumbles to her feet just to hear Will whistle loudly to get their attention.

Seeing she is alive everyone walks/limps into the building, with Simmons leading the way.

"Alright here is the situation all of you have had contact with NBE's, some more than others."

One soldier who Tia learned was called Epps asks "NBE's?"

Simmons without pauses snaps "Non-Biological Extra-terrestrials. Try and keep up with the acronyms."

Tia turns to Epps and mutters "Don't worry he's just an asshole."

Simmons hears her and turns to face her but pales as he sees her evil smirk, she was sending his way.

Stuttering slightly Simmons says "What your about to see is completely classified."

The trio and the soldiers enter the room just to see a 35-40 foot silver, evil looking robot frozen in the middle. Tia stumbles slightly as she looks and Megatron and a red light flashed across his glazed over optics.

Tia snaps out of her shock and hears the last part of Simmons explanation to Sam about his grandfather. As she turns to the rest of the rest of the group she doesn't see Megatron move slightly towards her.

John Keller then turns to Simmons "And you didn't think that the United States military may have needed to know that you were housing a giant hostile alien robot frozen in your basement."

Tom Banacheck then snaps "Until these events, we had no credible threat to national security."

But John snaps back "We you got one now."

Will then askes "So why here, why Earth?"

Sam then turns to me and I nod at him and then he says "The Allspark."

Epps then says "Allspark? What is that?"

Tia clears her throat and says "Well, the Autobots and Decepticons, they came to Earth looking for this cube like thing. Mr NBE here, AKA Megatron, that's what they call him. He is the bringer of death and destruction and he wants to turn Earths primitive technology to take over the universe. That's there plan."

Simmons turns "Are you sure about that?"

"Yeah, wait … You know where it is don't you?"

Simmons and Banacheck glance at each and Simmons says "Follow me."
