A/N: Ok, so this got in my head somehow. Also, I know that I have at least three other fics I need to update… I'll get to them eventually… Maybe after I get this whole Rise of the Guardians thing out of my system. Anyways, review please!

It wasn't all that odd when it started snowing during the Avengers newest battle with Loki: animated statues overrunning Central Park while the megalomaniac laughed. After all, it was November in New York. They generally got a little snow. The sudden ice underfoot was both inconvenient and strange, with the way it just appeared, but they had bigger things to worry about. In fact, they didn't notice anything was wrong until Loki's look of gleeful malevolence turned to outright anger. They braced themselves for a new attack, wondering what had set him off.

"Frost! I told you to stay away from here!" Loki bellowed, aiming a strike at what appeared to be thin air. Instantly, Thor's face lit up and looked around until he was gazing at the same spot Loki was.

"Jack! Where have you been?" He greeted enthusiastically, striding forward to embrace…nothing. As soon as Thor stepped back, Loki's eyes narrowed.

"Why, you impertinent little…" He hissed, lunging forward. The Avengers braced themselves to move forward and defend Thor, although wondering what was going on. Did the brothers have an imaginary friend? But a snowball hit Loki in the face, stopping him in his tracks.

"Um, who threw a snowball?" Tony asked, landing and flipping up his faceplate. Thor looked back at them, obviously confused.

"Can't you see him?" The god of thunder asked. Tony raised an eyebrow.

"See who?"

"Jack Frost, you idiot." Loki spat, still wiping his face. Tony laughed.

"There's no such thing as Jack Frost, he's a kid's story." He informed the two brothers. Loki laughed now, but there wasn't much joy in it.

"You see Frost, they don't believe. They never will." He claimed, then dodged another snowball that appeared out of thin air, only to retaliate with a blast of magic. Thor ignored them in order to turn back to his team, a delighted look on his face.

"That's it! You must believe in him, then you'll be able to see him!" He exclaimed. Tony raised an eyebrow.

"Oh, so then we can all keep each other company in the mental hospital!" He mocked.

"Tony. Just do it." Steve ordered. Tony rolled his eyes.

"Fine. I believe in Jack Frost." He said in a bored voice. Instantly, like a green screen effect, there was a boy there, floating in the air. Tony's eyes widened and he studied him a little more carefully. White hair topped a pale face made up of bright blue eyes and a cocky grin. He had on a blue, frosted hoodie coupled with pants that looked about three centuries old and no shoes despite the cold. In his hand was what looked like a shepherd's crook.

"Holy- do you guys see him? Or have I gone mental?" He exclaimed, rubbing his eyes.

"I see him. I'm still working on believing it though." Natasha put in. Loki rolled his eyes.

"You mortals are so small-minded. You will believe that there are whole other worlds out there, but you won't even believe in the spirits in your own." He waved a hand and disappeared in a burst of green smoke. The Avengers stared at the spot where he was, then reverted their attention back to the teenager who was now sitting atop his staff, showcasing amazing balance. He grinned and waved.

"Hey."

Thinking about doing another chapter with the scene from Jack's point of view... Thoughts? Review!
