Summary: When Loki falls from the Bifrost, he lands in a world very similar to Migard but with a few differences...

Thor/Young Justice Xover. Old team. Because it had to be done. :)

Chapter One

Memories flashed through Loki's mind, zipping through his head as the glittering colors of the world he grew up in fell away. They were mostly of his brother; Thor smiling, Thor eating, Thor breaking things—Thor doing everything, really. They were all from when he was younger, when he still thought himself an equal. When he was still happy. And then the shadowy mists of the ether closed over him, obscuring his view of his home for the last time, and his consciousness faded away.

Loki blinked his eyes open to find himself on a small but comfortable white bed, feeling weak but otherwise unhurt. Looking around, he realized he was in an infirmary of some sort. But that made no sense; he clearly remembered falling off the Bifrost into nothingness. So how had he ended up here?
The metal door slid open to reveal a man dressed in a black, skintight suit and cape. Over his head, he wore a cowl with horns pointed skyward. He did not appear to be wearing any armor, which struck the god as odd. Loki reached for his magic in case the visitor was hostile, only to find it was weaker and harder to use, much like it had been when he was—
His breath hitched in his throat as he caught sight of his form in the steel door that slid shut behind the man. It was how he had looked when he and Thor had been close friends and brothers, from the time he had been remembering as he fell. Had those memories somehow triggered his shapeshifting abilities? After all, much as he was loathe to admit it, he did not have a firm handle on that particular skill set yet.
"Hello," the man spoke in a deep, scratchy voice. He had not moved from his position by the door after coming in, and had seemed to analyze Loki's expressions.
"Hello," Loki replied shakily, fixing his green eyes in the holes of the man's black cowl. "Who are you and what are you going to do to me?"Loki refrained from asking where he was, much as he wanted to; it would do no good to divulge that he was lost. He suspected he could be in Midgard, but he wasn't entirely sure.
"I'm...Batman," the man said, shaking his head slightly as if he had expected to be recognized. Loki wondered briefly if he was the king of this land, then shook that thought away. "All we want is to heal you, and to see if you have any meta abilities. We detected some unusually high readings when you fell in front of our mountain." So they had some sort of device that could sense power levels (as Batman probably meant by 'meta abilities', Loki reasoned, though he wasn't sure), and Loki had landed in front of some mountain, near or in which, he supposed, he now was.
Loki looked down at himself. Besides the change in his age (he was only a few centuries old now), his clothing was the only thing different about him. Instead of the gilded green tunic and cape ensemble that was his usual wardrobe, he was wearing a strange, loose-fitting greet shirt with short sleeves and slightly bluish pants made of an odd material. His magic was still too weak to change his clothing as he usually could; at this point in his life, he had only been able to create small, insubstantial objects, a single, weak duplicate of himself, and teleport short distances. His healing magic, however, had always been a strong, natural thing, so that was unaffected, which was good. "I am healed now. So what will you do to me?" he asked.
Batman tilted his head. "Healed...? Impressive. If you would accompany me, we will have a little talk to see who you are."
Loki rose, shaking his head to clear the dizziness, and walked over to Batman, who snapped a pair of handcuffs on the young god's thin wrists 'just in case'. The tall man then led his small charge into a room devoid of all furnishings except for a desk and two chairs. The door slid shut behind them with a resounding clang. Batman sank in one chair and gestured for Loki to sit in the other. This is an interrogation, Loki realized. It was quite obvious the man had no idea who he was and was simply taking precautions to see if he was hostile.
"Let's begin," Batman said simply. "Who are you?"
"Loki," the god replied, not bothering to come up with a fake persona.
Batman seemed unfazed. "Last name?"
"No," Loki responded without missing a beat. It was true, in his mind, anyway; he had no idea what to call himself. He was no longer Odin's son—the old god had made that much clear at the end of the terrible battle on the Bifrost—and he would be dead before he thought himself son of that horrible monster who'd sired him.
Batman just nodded. "Where are you from?"
Loki knew he couldn't say the truth, so he said the first Midgardian place that came to mind. He had already determined this was Midgard, albeit a different place Thor had been sent. "El Paso, New Mexico."
"Age?"
Loki thought for a second. The Midgardian equivalent of his current appearance was... "Sixteen."
Batman nodded and scribbled something on his paper. "What is your power?"
Loki noticed how he'd said 'what is your power' and not 'do you have any powers'. He'd obviously inferred that Loki had somehow gone from New Mexico to wherever they were now. Obviously, he was a long distance away from where Thor had been. Good. However, Loki was not about to simply tell this man everything he could do, so he replied, "I don't know yet."
Batman cocked his head. "All right. Wait here a moment." He got up and left the room, returning a few minutes later with a pale, redheaded girl wearing a strange assortment of pink and white clothing. They shared a glance, and then the girl sat in the unoccupied chair while Batman stood by the door. The girl leaned across the table and lay her hands gently on Loki's head. He immediately pulled away. He knew this pose; he'd used it himself far too often to count. It was how he read people's thoughts.
The girl smiled gently, taking his resistance as uncertainly. "My name's Megan," she said in an overly cheery voice. "I won't hurt you." Then she lay her pale hands on Loki's head and closed her eyes in concentration. When she opened them, they were glowing. When Loki felt the tendrils of Megan's mind, he was ready. He'd pulled out a few of his memories that didn't involve anything specific to do with what he was trying to hide, and altered them to fit in with the bits and pieces of modern Midgardian culture he knew from Thor so that it looked like he had a normal, if eccentric, family and life. Then he crafted a memory in his head of a terrible fire sweeping through his happy home, burning everything in his path, and him trapped in his room, terrified out of his mind as the flames creeped closer, and then the burning room folding around him and then waking up here. Yes, that was believable. So, armed with these false memories, Loki was ready for Megan when she invaded his mind. If he had been at full power, he could have looked into her memories without detection while feeding her the false ones, but in his weakened state, he was only capable of the latter.
"You poor boy!" Megan exclaimed as she withdrew from his mind. Good; the false memories had fooled her. With a sad, apologetic smile, Megan got up and went over to Batman, obviously to report what she'd seen. After a short conversation, she returned.
"Um, we, the Justice League, have a team that..." The redhead trailed off as Batman shook her shoulder.
"The Justice League has a team of younger heroes to go on covert missions. I believe they can help you find your powers," the dark-clothed man summarized. He obviously expected Loki to know what the Justice League was, so Loki didn't bother to ask. He'd find out later. As for this team...Batman had mentioned they were considered heroes, so it wouldn't be a good idea for him, a monster, to be a part of it. Still, it would probably be the easiest way to fund out what he needed to know, like where he was, exactly, and how to return his appearance to its former, older state. Batman unlocked the handcuffs still binding Loki's wrists and Loki stood, rubbing his wrists where the metal had chaffed them. The tall man lay a hand on Loki's shoulder and shoved him less-than-gently forward through the door, Megan following close behind. The trio walked through several hallways, all with the same featureless metal walls, until they reached what seemed to be a gathering place of some sort built directly into rock, as evident by the fact the walls were rock themselves. The room was devoid of any furnishings except for a raised dais in the center and a row of circles inscribed with some kind of swirling pattern along one wall. Batman put a hand to his ear and murmured something. There was a blur, and a boy with hair redder than Megan's materialized in front of them. He had large green eyes and freckles, and wore a strange white shirt and the same odd blue pants most of the Midgardians Loki had seen while watching Thor wore. His smile was lopsided and he had a joking air about him. Loki immediately disliked him, though he wasn't sure why. After about a few minutes of awkward silence, a group of other teenagers walked into the room. There was a tall, muscular boy with black hair and startling blue eyes, and his shirt had an 'S' inside a shield. Beside him was a smaller boy, also with black hair, who wore a black and white ensemble and a pair of dark glasses, the reason for Loki couldn't fathom. After them came a tall, dark-skinned boy with a shaved head and sea-blue eyes. Next to him was a tall, girl with a faint tint to her skin and grey eyes. Her blonde hair was longer than Loki had ever seen hair before, even on women. Behind the two of them walked a shorter, dark-haired girl with pale blue eyes. Loki, sensing magic on her, smiled slightly. Megan giggled and jumped into Loki's line of sight.
"This is the team!" she exclaimed giddily. "Guys, this is Loki. He has some super powers, and needs our help to find out what they are! Loki, this is Wally—" the redheaded boy nodded at the god with a self-satisfied smirk, and Loki inwardly rolled his eyes. "—This is Conner—" the muscular boy with the 'S' on his shirt gave a small wave. "—This is Robin—" the smallest boy grinned widely. Loki wondered how old he was. The boy seemed young for crime fighting, so this must be some kind of special circumstance. Maybe he was the one that organized things but didn't participate. Like Loki. Loki began to take a liking to the small boy. "—This is Kaldur, he's the leader—" the dark-skinned boy nodded. "—This is Artemis—" the blond narrowed her eyes in suspicion, glanced at Batman, then gave a tiny wave. "—And this is Zatanna!" the girl Loki had sensed magic on waved, and Loki allowed a small smile to slip through. So they had a mage. Good. This would make things a lot easier. Batman began to speak, breaking Loki out of his thoughts. He told the teenagers how Loki had appeared out of thin air in front of Mount Justice (which was, Loki gathered, the mountain they were currently residing inside). Then, as the black-clothed man went on summarize what had happened after Loki awoke, the god allowed his mind to wander. He'd always been good at sensing the general power levels of other people; just from observing, he could see that Zatanna was the only mage in the team. Kaldur had some magic, but it was tied to an element, which was too limited and uncontrollable to be of any use to Loki. Wally had some sort of magic, but it seemed more like the magic he'd observed Jane doing; the magic Midgardians called science. This type of magic was chaotic and vastly unexplained, so Loki held no interest in it. Megan's magic was tied to her self; she could do simple spells and read minds, but could do nothing to help Loki. Conner's magic was of the same sort, but weaker and blocked by some sort of shield. If Loki got to know Conner well enough and was feeling particularly giving, he may help the boy breach that shield and reach his full potential. Maybe. Robin and Artemis had no magic whatsoever, Loki realized with surprise. It made no sense that they would be in this team, but he supposed they had their reasons.
After Batman ended his synopsis of the recent events, Artemis spoke up. "How do we know we can trust him?"
Batman nodded at Megan, who smiled sadly. "I looked through his mind. He never had any knowledge of power, and his family was normal, but then...there was a fire, and he got scared and teleported here. Batman's instruments picked up that he has high power levels, but he doesn't know what he can do yet. His past was that of a normal civilian, and I looked through all his memories." Artemis nodded in understanding, but Loki had to stop himself from laughing. Either he'd done a better job than he'd thought, or Megan was very unobservant. His hastily crafted cover had worked perfectly.
"So...what now?" Wally asked awkwardly.
"Test him to see what he can do," Batman replied and then, with a sweep of his cape, he slipped away.
"Hey," Robin said, stepping up to Loki. "I like your name. You got a last name?"
At Loki's shaking head, he scowled. "Everyone's got a last name. You had a regular childhood; obviously you have one." "
I didn't. Please stop asking," Loki replied. This was a large tear in his carefully crafted plan; he was undermining his 'normal' past by having no last name. Well, he could probably still play this to his advantage. "I—my family's gone. I don't have a..." He trailed off with what he hoped was an appropriate amount of depression. Robin put a hand on his shoulder and turned to the others, who were standing awkwardly by the door thy had entered.
"C'mon. Let's get Loki acquainted with what we have here. He'll be feeling the aster again in no time." With that, the small boy sauntered off into the connecting room, a living room, after his teammates, leaving Loki standing slightly dumbstruck in the entryway.
"...Aster?" the young god whispered.
