Iron Man, AKA Tony Stark, gasped, his face paling. Pepper hadn't answered, and now he was going to die in space.

Alone.

Admitting his defeat as his suit lost power, Tony closed his eyes. The light in his chest left, leaving the explosion from the bombed Chitauri ships as the only bright light. His body went limp and he fell through space back towards the portal. The large hole was beginning to close in on itself, sucking anything in a relatively close distance into it.

Eyes pointed upwards, the Avengers waited with anticipation for Stark to appear. After a while, Captain America spoke up, his voice emotionless.

"Close it."

Upon hearing the command, Agent Romanoff took her eyes off the portal and towards the Tesseract's crown. The sharp end of Loki's staff tapped it, and the portal hitched. Natasha yanked the scepter back and watched the skies.

At the very last second, the Man of Iron fell through the portal.

Along with something else entirely.

Thor glared at the mysterious object that had followed Stark out of the portal. "What is that?"

"I don't know. For all we know it could be alien," Rogers responded.

"But what about Tony? He's not slowing down. Get him!" Natasha's voice came from over the intercom.

Tony Stark was at building level now. Thor began swinging his hammer, preparing to take off, when the Hulk came flying through a building and swiped the limp man out of the air. The green beast left a huge dent in the wall and began sliding down the building. Tony hung like a rag doll in his arms as the Hulk threw himself down to the ground onto his back. As he gained his bearings, he snorted before pushing Stark off unceremoniously, where he landed with a clunk.

The other Avengers raced towards them, coming to a stop. Agent Barton remained unseen somewhere in the wreckage. Thor leaned down and ripped Tony's mask off in one swift movement, where it skidded across the pavement. They waited in anticipation, unsure of what to do. Stark's chest was dark.

Agitated, Hulk shuffled a bit. He clenched his fists and reopened them, letting out an alarming roar. The other Avengers started, looking in surprise.

"Ahh!" Tony shrieked in alarm, his center light springing to life. He gave a few heaving breaths, glancing around. "What the hell?" Deep breath. "What just happened?" A small break as his eyes flicked across the gathered heroes. "Please tell me nobody kissed me."

Captain America glanced around, breathing harshly. His eyes squinted, he blew out a breath. "We won."

Tony tried to lift an arm. "Alright. Hey, alright. Good job guys. Let's just-"

BOOM.

The ground shook beneath their feet. They readied in alertness. Steve put his finger to his ear.

"Romanoff, what was that?" he asked.

"Uhh, you know that thing that fell from the sky? It just landed," came the shaky response. "And you might want to come look at it. I can see it from where I am."

"On our way. Is Barton with you?"

"Here," his voice popped up from Natasha's earpiece.

"Good. We'll be there in a sec." Steve looked back towards the others.

"I must get Loki. Go on without me once up there. I shall take care of him," Thor stated. Captain nodded and then helped the downed Iron Man up.

"Ugh, get me out of this thing," Tony mumbled, falling over again.

"What is that?" Banner asked, back to his normal self and in new clothes.

"Um, looks like a box," Natasha said simply, shrugging. The blue box was laying on its back, smoking. Scorch marks were tracked over its surface.

"Well, that's because it is. In fact, it's a Police Box from the '50s. No idea what it's doing here, though," Stark claimed, approaching it. He was out of his suit, leaving him defenseless, but whatever this was didn't look very dangerous.

"Not to mention it fell from space," Barton added, getting his bow ready with a snap.

Before they could get any closer, the ground rumbled. There was a small click heard and the box shook. It hovered in the air for a moment and then settled back the right way up. The Avengers stood in silence, waiting.

A blue door swung open. A man, wearing burnt and ripped clothing, fell out. He managed to look up long enough to see where he was, and that was it. He collapsed without a word. The door on the Police Box carefully swung shut, leaving the man outside.

Tony quickly bent down, checking for a pulse. "He's alive, but just barely. We need to get him inside the tower."

"No, Fury's sending a jet," Thor remarked, landing with a thud next to the Police Box. "It should be here-"

"Now," Romanoff said. The rumble of a jet came from above them. It landed and the drop door lowered.

"What happened to Loki?" Captain America asked Thor.

"He is already on a separate path, back to Asgard. They were expecting him, so to speak," the demi-god announced as he fiddled with a band on his wrist.

"Come on then; get this guy on board," Barton grumbled. Thor stepped forward and picked the fallen man up, slinging him over his shoulder.

"What about the box?" Romanoff asked.

Steve glanced at it. "Get it on board."

They quickly shuffled onto the jet while Barton, Steve, and Tony found out a way to push it onto the ship. Thor set the limp man on a cot. Bruce began working on his various wounds and burn marks. As soon as they transferred the blue box onto the ship, they took off.

"So, any idea who this guy is?" Rogers questioned after a few minutes of silence.

"No. He seems human," Banner replied as he undressed him to get a better look at the wounds.

"Yeah, well, Thor looks human, but he's not," Natasha scoffed.

"We're going to have to run a few more tests before we can diagnose him as alien. Though he did fall out of a box from space, so it wouldn't be unlikely," Bruce mentioned.

"What in the world is this?" Tony asked as he held up a strange silver object tipped with blue that he had found in the man's pocket. He tried to figure out how to work it, but failed.

"Probably not this world, I'm guessing," Barton mumbled, almost inaudibly as he shined his bow.

The strange man was transferred inside, where Director Fury was waiting. He narrowed his eye suspiciously as they rolled in the man on the cot.

"What the hell is this? You can't go about rescuing civilians and bringing them here!" Nick Fury exclaimed, pointing to the man.

"That's the thing. He's not a civilian. He fell out of the portal with Stark," Rogers answered, jabbing a thumb back at the genius.

"In a box," Barton added airily. After studying the man for a few moments, the Director growled slightly in the back of his throat.

"Fine. Get him to the medical wing," Fury ordered.

New story! Woo! I got kinda bored while reading fanfiction, so I made this!

It will be epic!

P.S. Don't expect a whole lotta updates on other stories if you happen to be waiting. Because this is my muse.
