Prologue

"I could have done it, father! I could have done it! For you! For all of us!"

"No, Loki."

Loki groaned in pain as he slammed into the ground on his side. Well, that hurt, of course. Even a god can feel pain. He opened his eyes, and tried to sit up. But his head was swirling in dizziness. Closing his eyes to shut out the world spinning before him, he collapsed back into the dirt. He tried to hold onto consciousness, but he slipped helplessly into the dark realm of his mind.

"Am I cursed?"

"No. Put the Casket down."

"What am I?"

"You're my son."

"What more than that? The Casket wasn't the only thing you took from Jotunheim that day, was it?"

"No."

Always that one word. No. No. No.

Somewhere, in another part of his mind, Loki could hear a loud beeping echoing, faster and faster. Someone was screaming, screaming, and he was sure it was him. As he fought his way back into the real world, he felt something, a needle, piercing his chest. Loki plunged back into the black depths of his subconscious.

After what seemed like centuries, Loki finally managed to struggle awake. As his eyes opened, he was greeted by a young woman in white clothing. Her name tag read "Madeline."

"Hello," Madeline said, smiling sweetly. Loki already took an instant disliking to her."I'm Madeline."

"Yes, I can see that from... whatever that is on your tunic," Loki croaked out. He looked at his arm and saw the tubes sticking out of it, leading up to a small bag filled with liquid. "What... where am I?"

"Okay, one, this isn't a tunic, it's a shirt," Madeline replied. "Second, the thing on my shirt is my name tag. Third, you're in the hospital. In Manhattan, to be exact."

"'Manhattan?'" Loki repeated. "Is that really what you mortals call this realm?"

"Wow, you must have gotten hit pretty hard on the head," Madeline commented. "I'm gonna get you something to eat, okay? You must be starving." With that, she left the room.

Loki reached for the tubes and quickly ripped them out of his arm. He hissed in pain, and bit his lip. The incessant beeping turned into a long, drawn-out ringing.

Loki let out an annoyed growl and threw off the hospital blanket and slipped off the bed, his bare feet hitting the cold floor. As he let go of the bed to shift his weight to his feet, he fell forward and hit the floor. Loki's head reeled in dizziness.

At that moment, another nurse came racing in. She grabbed Loki and tried to pull him towards the bed.

"Let go of me!" Loki snarled, trying to tear himself from her grasp. "I am Loki of Asgard! You will release me at once!"

"You'll be discharged when you're in proper health," the nurse said, shoving him into the bed, "and when Mr. Stark has paid all the fees for your surgery."

Loki desperately reached for his magic, in the part of his mind he knew it would rest, but it wasn't there. "What did you do to me?" He clawed her face, his fingernails tearing her flesh. Immediately bloody gashes appeared on her face. "What did you do to me?!"

A needle punctured Loki's neck and he blacked out.

"Is the throne really worth what you've done? What you've become?"

"I never wanted the throne! I only wanted to be your equal! Now fight me!"

"I will not fight you, brother."

"I'm not your brother. I never was."

When Loki woke up again, he saw a dark-haired man sitting in a chair across from the bed. The man was watching him curiously. "Was wondering when you'd wake up."

Loki said nothing in reply.

"The name's Tony Stark." Tony waited for Loki to say something. He didn't. Tony continued, "The nurse said you said your name was 'Loki of Asgard.' Right before you slashed up her face with those fingernails of yours."

Loki continued to ignore him.

"So were your parents Norse fans or something?"

"Do you ever shut up?" Loki finally snarled.

"Uh, last I checked, no," Tony replied. "Nice to know you can still talk, by the way."

"Why am I here? What did you to do me? Where are my powers?!"

Tony looked at Loki with raised eyebrows. "Powers? How hard did you hit your head?" He shook his head. "Never mind, I'll start from the beginning. I was at a campground with my girlfriend, we were out hiking, and we found you unconscious in a smoking crater. We called an ambulance and now here you are."

Loki let out what sounded like a snort. "Right, mortal. Here I am."

"You mind telling me what you were doing there?" Tony asked. "In that crater?"

"Yes, I do mind, actually," Loki replied. "Maybe if you explained what happened to my magic, I'd tell you."

"Can't do that," Tony told him. "I don't know what happened to your... uh, 'magic.'"

"Liar!" Loki shrieked. He tried to lunge at Tony, but found he was restrained by a band stretching across the bed and over his body. "Release me! Now!"

"Can't do that," Tony said, unimpressed. "Doctor's orders."

"I told you to release me! You will do so! Right now!" Loki continued to try to struggle out off the strap, but couldn't. "I am Loki, the rightful ruler of Asgard! You will obey me!"

Tony just shook his head and left the room.

"I will out of here!" Loki screamed. "And when I do, I'll kill every last one of you mortals! Every last one of you, do you hear me?!"

. . .

So that's the end of the prologue. I guess this should technically be in the Avengers category, but whatever. I'll just roll with it.

Constructive criticism is appreciated, FLAMES are NOT. Thank you.
