A/N: I had an idea for this story when I was complaining about how hard it was to write a Halo fanfiction story to my friend, and they suggested that I write a crossover of The Avengers and Halo instead.

This story will take place before Halo 4 when Chief and Cortana are still stuck on the Forward Unto Dawn, and when Iron Man is taking the nuke into space… except he misses the vortex back into Earth. Hopefully future chapters will turn out longer! Please let me know if you like!

Chapter 1;

Well, this is it. Tony Stark, billionaire, genius, playboy, philanthropist, and Iron Man thought as he plummeted towards the rapidly closing wormhole. Tears formed in his eyes - immediately freezing since he was in space - as he thought about how he would never see Pepper again. Or Rhody. Or Happy. Or even the Avengers, he doubted that even Thor - weird alien that he was - knew what deep and dark space that the man was in now. It's too late. Tony thought. I never got to marry Pepper, I never got to tell Steve that he isn't actually all that bad, I didn't get to play pranks on Clint, or do Scientific stuff with Bruce, or get to know the real Natasha all that well. Hm…. I expected my life to be flashing before my eyes at this point, but I guess dying is just overrated. I wanted to see Pepper's face just one last time, but now I can hardly recall it…

His suit was breaking down, his oxygen filters were freezing over - breath was becoming hard for Tony. The freezing cold was creeping up his body, the man could feel his organs slowly shutting down, the nuke he had brought into space exploding the Chitauri ship before his flickering vision. His call to Pepper hadn't gone through, and he had disconnected from Jarvis. In his last minutes, the ailing billionaire was well and truly alone.

And down his body plummeted; down, down, down, down, towards the rapidly contracting wormhole to his only chance of salvation. His metal laden body fell closer, closer, closer… but not close enough. With seconds to spare, the wormhole completely closed…

And Tony was still in space.

Dying.

Alone.

So this is the end. He thought dryly. Huh. So I'm not killed by some big bad super-villain - not directly, anyways - or my stupid heart. Not that space is much better, I have to admit. And if I had to choose between the three of them, falling to some world-conqueror actually sounds pretty coo-…

At this point, Tony's brain wasn't able to function well enough to form any sort of coherent thought, but a morbid sense of acceptance fell over the genius playboy. This is the end.

He was ready to die, he had made his mark in the world. Not nearly large enough for him, admittedly, but hey, who was he to be choosy? He was in frickin' space.

He was going to die.

And that was okay.

It was all over now…

There was nothing anyone could do…

But then, his body made impact on something… large. And metal. And not space.

And so Tony, with his last sliver of consciousness, began fighting the inevitable.

But even the most valiant of efforts would save him only a little more time.

He couldn't make it on his own.

But, unaware to the heroic man known as Iron Man, this blow hadn't just woke him up.

Cortana was awakened by a sudden impact on the ship.

What…? She wondered slightly groggily. She brought up the scanners, and checked out what had passed through their somewhat unstable shield systems.

At first glance, it wasn't much. Just a small, insignificant piece of debris that had slipped through their shields. Nothing of importance. But just as she was about to dismiss it, some instinct stayed Cortana's holographical hand. She didn't know what, but it was most certainly something. She took a closer look at the hunk of space junk that had impacted the Forward Unto Dawn. Cortana's nonexistent eyes widened.

Was it…? No. It couldn't be. Of course that wasn't shaped like a man. But just to be sure, Cortana switched sensors.

[No…] she gasped. For, indeed, this piece of metal was showing vitals. They were weak, whoever it was shouldn't even have technically been alive, but it was. Cortana decided to move past that, this person needed help. No matter how slim his chances were, Cortana would be damned if she didn't at the very least attempt to save some idiot's life.

However… She looked down uselessly at her illusionary hands. She was incapable of physically helping that person out there, which meant she only had one option…

[John…] she said urgently. [John! Wake up!]

A/N: All mistakes made by me, I don't have a Beta. New chapter should be out soon, please send me a review!
