This is my third crossover. I wrote another fanfic introducing Jenny, the Doctor's Daughter, into the cartoon series Avengers EMH, this story is introducing Jenny into the Marvel movie-verse. I see her as a much needed expert on aliens, similar to when the Doctor was called to UNIT. Jenny would be called in to help with tracking down Loki along with the Avengers. If you haven't read Evolution of the Cybermen, please check it out, it is completely unrelated to this story, but if you enjoy this, I think you'll enjoy Evolution of the Cyberman. I also wrote another fanfic, No Ordinary Organisation, which crosses over No Ordinary Family and Alphas. If you enjoy either of those shows, please check this out as well, I haven't had any reviews for it. Thanks, Rossaldinho.

Earth's Orbit

Jenny had had nothing but bad luck since she joined the Time Agency. First, she had never really been on a proper assignment, the Time Agency had assigned her to running patrols and computer work. Secondly, on her few assignments out in the field, she was constantly being side-lined while her male colleague went on the front lines. Eventually, it got to such a point that she decided to leave her partner and work solo. Her first assignment as a solo Time Agent was being sent to this planet to track down a time agent there. Thirdly, her ship was crashing.

She watched through her forward viewport as her ship heated up as it entered the upper atmosphere. She thanked the stars that the pressure stabilisers were still working, and stopped her from being baked inside her ship. Not that it'd matter, her engines were still burning. She was unlikely to land before all of her engines failed. It was time she prepared herself for the inevitable. She was about to die. It was ingrained into her programming as a soldier. Dying was always the inevitable consequence of fighting in a war. Perhaps it would hurt, perhaps it would not, but there was no way to really know… Jenny continued her philosophical debate about what would happen after death, preparing herself for what was to come.

Stark Mansion

"Sir, we have a problem," said the voice of Jarvis

"What's the problem, Jarvis?" said Tony as he worked on his armour.

"There seems to be a projectile heading for this house," said Jarvis "A large projectile."

"A missile?" asked Tony

"Bigger," said Jarvis "I'd guess a satellite, but it's trajectory is wrong."

"All right," said Tony "Call Rhody, I'll need his help on this one, I'm going to suit up."

Tony deployed the Mk IV armour, suiting up and flying out of his house, heading towards the projectile.

"That's no satellite, Jarvis," said Tony "That's a spaceship, Rhody, where are you?"

The War Machine suit flew into view just as he spoke "Right here, what are we looking at?"

"I don't know," said Tony "Jarvis doesn't recognise the tech, so nothing we've seen before, there seems to be a working communication system on the ship, I'm trying to patch in."

As he said it, a voice came from the speaker on his helmet "This is Captain Jenny of the Swiftrunner, are you receiving, engines are failing, emergency eject non-functional, need immediate assistance, please respond."

"This is Tony Stark," said Tony "We'll get you out, Rhody, prepare to get her out, I'll get underneath and see if I can patch the engine."

"On it," said Rhody, matching speed with the crashing ship.

As Tony looked at the tech on the engine, he realised that the tech wasn't anything he recognised.

"I don't recognise any of this technology," said Tony "I don't want to tamper with it in case it gets worse, Rhody, get her out."

"We can't yet," said Rhody "The air pressure would kill her."

"We need to, Rhody," said Tony "The ship could blow any minute, get clear, I'll get her out."

War Machine broke off and Tony flew around, using a small laser to cut the canopy and push it off the other side. Captain Jenny unbuckled her seatbelt and stood up, holding out her hand to Tony.

"You'll need to hold onto me, around the neck," said Tony from the Iron Man suit "I need my hands for flying."

Jenny held tightly around the Iron Man suits neck.

"Jarvis, activate the shield," said Tony

"Are you sure that's wise sir, it's not finished testing yet," said Jarvis, a note of concern in his voice

"If we don't use it, Captain Jenny might die," said Tony "It should stabilise the air pressure."

"Activating shield," said Jarvis

The shield surrounded both of them.

Below them, the spaceship imploded on itself, the shockwave being swallowed by a temporary wormhole opening.

"What happened there?" asked Tony,

"Wormhole converter," said Jenny, in a tired voice, nodding as if she was very tired "Security device to stop ships from crashing if there's nobody in it, it's…" Jenny trailed off. Looking down, Tony saw that Jenny had fallen asleep on his armour.

"You should get back to the mansion, sir," said Jarvis "The air is too thin for her up here, we need to get down to ground level where the air is thicker."

"Copy that, Jarvis," said Tony, flying off in the direction of the mansion, using cables to hold Jenny in place so he could use his repulsors in his hands to keep up speed. It wasn't long before they arrived back at the mansion.
