Author's Note: So here's the thing; I love genderswap fics. But not the AU kind where the character has been the opposite gender their entire life, I like the ones where a character is suddenly switched and has to figure out the new mechanics. But there aren't enough of those, in my opinion. So I wrote one. You're welcome, and enjoy.

They had only just fixed New York from last time. The citizens had all but forgotten the tragedy, and everyone was continuing life as normal. Sure, the Avengers still had the odd threat to deal with, but what was Dr. Doom having a temper tantrum compared to this?

Loki was at it again. And damn it if Tony wasn't pissed.

"Can we get this over with soon?" He said over the comm as he aimed repulsor beams at their green-and-gold clad enemy. "I get grumpy if I don't have my coffee in the morning."

"You can get your caffeine fix later, Stark." Clint retorted from two blocks away, where he and the others were fighting off Loki-clones that popped like balloons after just a few strikes. They were easy, yeah, but there were so many of them that this particular team had their hands full. "Right now we have reindeer games to deal with."

"Hey! I'm pretty sure that's my line!" Tony said jokingly. He was catching up to the god, who was fast when he was running on magic. He finally landed in front of him, stopping Loki short. "You know, the first time definitely made an impression, but by now you just seem kind of desperate." He said, swaggering toward him. "What are you even trying to accomplish this time?"

Loki smirked. "A foolish mortal such as yourself would never be able to grasp the complexity of my plan. Had it never occurred to you that you may have been playing into my trap this entire time?"

"Actually, no it hasn't. Not since we kicked your ass and sent you crying back home, anyway."

Loki grimaced. "Very well then." He said. "Let's see what you have to say after I level your precious city!" He raised his staff menacingly.

"Ohh, no you don't!" Tony shouted. He lunged forward and grasped the staff with both hands, and the two began to wrestle over it.

"Stop that! You have no idea the power you're toying with!"

"I'm sorry, is baby scared his rattle will break?" Even as the words left his mouth, Tony started to worry. He didn't want to accidentally hit the trigger or something and end up shooting magic everywhere. Too late.

The staff banged against a piece of rubble, and everything happened at once; a crack, a flash of green light, and then… black.

The next thing Tony remembered was the smell of disinfectant. The distant sound of beeping. A hospital? Yes, that sounded right. But what was he doing there? There had been a battle, he knew that… he must have gotten scuffed up pretty bad.

"He's waking up!" He heard someone whisper from the side of his bed. He opened his eyes to see Pepper staring down at him. Sitting next to him was Clint, who looked like he was about to laugh. "Hey, Tony, are you okay?" Pepper said. "Does anything hurt?"

"No, not really." Tony replied. He frowned; his voice sounded higher than usual. He coughed and continued. "They must have me on some pretty strong stuff." No, clearing his throat hadn't helped; he still sounded like a chick. He put his hand to his throat, and suddenly it hit him; his hands were smaller too. He held them out in front of him and examined them, still battle-worn but now small and dainty.

"Guys, what the hell is going on?" He said in that high, goddamned voice.

"Um, that's the thing-" Pepper started. She didn't get far, though, before Clint cut him off.

"Dude, you're a chick."

"Ha ha." Tony laughed nervously. But… but wait. He shifted a bit in the sheets. Something was definitely missing. Something very important. "Where the hell is my dick!?" He shouted.

"And that's not all." Clint said, obviously amused. "Look down."

Tony did, pulling the collar of the hospital gown away from his chest. "Holy shit… I have boobs!"

"I was going to break it to him gently, Clint!" Pepper chastised.

"How? The dude went from being, well, a dude to a girl! I'm surprised he didn't notice when he woke up!"

"It's not something I normally give much thought to, Legolas!" Tony shouted. "I don't wake up and immediately think, 'gee, am I still male? Better check!' Once again, what the hell happened?"

Clint opened his mouth, but Pepper quickly put her hand over it. "You and Loki were fighting over his staff, right?" She said. Tony nodded. "While you were fighting something must have gone off and… here you are."

"Oh shit, I forgot about that! Where's Bruce? And more importantly, Loki?"

"Well, Bruce is in the waiting room with the others."

"And Loki?"

"Well, that's the thing. You weren't the only one affected by the blast."

"What do you mean? Where is he?"

"He's in the waiting room too, he's-" Tony wasted no time in hoisting himself out of the bed, detaching all the equipment, and marching down the hall toward the waiting room. "Wait, Tony! You need to rest!"

"Aside from a very unsettling shift in equipment, I think I'm fine, Peps!" Tony said, grumbling a little as he turned the corner to where the others were seated. Everyone looked up to face him, startled.

"Tony, you shouldn't be out of bed!" Bruce said. From the lack of surprise on everyone's faces, they had all been told about his predicament.

"I don't give a rat's ass about bed rest. Where's Loki?" At that, everyone pointed at the floor. Tony turned to see a small child of about seven years old with black hair, wearing clothes that were just a bit too big for him and studying one of the spot-the-difference games in a Highlights for Kids magazine. It took him a second to register, but then Tony realized; oh shit. This was Loki. "That's him?" He said. "That's Loki?"

Loki turned to face him, and yes it was definitely reindeer games. The eyes confirmed it. "Are you looking for me, ma'am?" He said.

Tony knelt down. "Yeah. Loki, do you know who I am?"

"Not at first, ma'am. But my big brother explained everything to me." Loki was smiling, his words with an innocent quality to them that the adult Loki would never show.

"Can you tell me what you remember before coming here?" Tony asked.

Loki looked up into the air in contemplation. "I only remember playing in the castle with Thor and Sif, and then I was here. Is it true I was all grown up before I came here?" Tony groaned inwardly. This was going to be interesting.
