A/N I was suddenly inspired to write this. (If you read my Kingdom of Albion story, do not be alarmed. I am not abandoning it, I just felt that I needed to start writing this story. I'll update that one next week).

If you've ever seen Hellboy, this is based off of that. I am trying to make it a little different, but the story is going to follow the plot of the first movie (Though some backstories and characters will change, and some characters may die that didn't die in the movie.) Also, Enjoy 3

Disclaimer: I don't own Merlin or Hellboy, because if I did I'd be the happiest girl on the planet.

What is it that makes a man a man?

Is it his origins, the way things start?

Or is it something else, something harder to describe?

For Professor Gaius Wilson, it all began in 1944 on a classified mission off the coast of Scotland. The Nazis had become desperate, combining science and black magic to upset the balance of the war. Being paranormal advisor to President Roosevelt, he and a small squad of soldiers quietly invaded the small island, not knowing that what they would find would change their lives forever.

Avalon Island, October 9th, 1944

11:49 PM

Gaius and the commander of the squadron, a man by the name of Odin, crotched in a low ditch and the young professor pulled a small wooden box from the large pack over his shoulder.

"Here," He opened the box and handed a large rosary to the old sergeant. "You and your men will each need one of these."

Odin chuckled. "Are you Catholic?"

"Amongst other things, yes."

Odin let out a small laugh before holding out his spare rifle. "Here, you'll need this." But Gaius shook his head at the weapon.

"No, I abhor the use of violence."

An uncomfortable silence fell between the two as the first few drops of rain began to fall. "Sergeant Odin," Gaius spoke up. "I hope you don't think me mad-"

"Three days too late for that, Professor Wilson."

The rain was coming down in sheets now, and the soldiers were becoming anxious. Finally, Odin had enough.

"You're wasting our time." He snapped. "There's nothing on this island but sheep and rocks."

"Ruins." Gaius corrected. "Not rocks. The remains of Trondham Abbey. Built on an intersection of Ley Lines, the boundaries between our world and the other-"

"That's a load of hog swallow. Before you joined, I'd never even heard the word 'parabnormal'."

"Paranormal and you read the transmission as well as I."

"What I read was a bunch of German nonsense, talking about ghosts and hocus pocus."

"I have seen ghosts, Sergeant."

Odin rolled his eyes. "Of course you have."

Their attention was brought away from the conversation when a large spotlight suddenly lit up beyond the rut they sat in. The squadron slowly rose up to peek over the edge and gaped at the sight of a large group of Nazis standing in the center of the ruins not a hundred yards away.

"I'm sure they're here for the sheep." Gaius whispered with a smug smirk. They moved out of the ditch to the outer walls of the ruins, watching as a hooded figure stepped into the center of the Nazis, where a large, circular machine stood. The hood lowered to reveal a beautiful woman with long dark hair and bright blue eyes. Gaius let out a gasp of recognition, but offered no explanation as the woman motioned to a man with two long blades in his hands and a metal mask covering his face. The man nodded and walked to the edge of the group, standing guard.

"The freak in the gas mask?" Odin looked to Gaius for answers.

"Myror. If he and Nimueh are here, this is worse than I thought." The young professor responded vaguely, attention firmly fixed on the ritual.

A burly man with short brown hair approached Nimueh, who smiled and handed him a large leather bound book. "No matter what, my work must continue." She whispered, placing a kiss on his forehead. "I grant you everlasting life, dear Valiant."

The man Valiant bowed low to her and left the small gathering hurriedly. Nimueh turned to face the Nazis. "It's time." She announced. One of the generals brought a large box to her, which she opened and pulled a golden gantlet from.

"Tonight," she proclaimed, putting the gantlet on her left hand. "We will open a portal, and awaken the Seven Gods of Chaos! Our enemies will be destroyed, all impurity being razed from our world, and from the ashes a new Eden will arise!"

She pointed the gantlet towards the circular machine and chanted.

"Wacan hlaford fram abysgian. Brengan feorr Emrys, Caeg fram Dóm!"

The machine flashed with golden light and a whirlwind opened inside.

A small flash of white lit up behind her for a second, but her attention was fixed firmly on the portal, knowing Myror would take care of any interruptions.

Geoffrey, one of the younger soldiers sitting behind Gaius, was forcibly pulled back behind the wall, camera still in hand.

"I was trying to document-"

"Listen here, you moron!" Odin growled. "You try something like that again and I'll carve you a new one, got it?"

"We need to do something!" Gaius hissed. "They've opened the portal! We need to close it before anything gets through!"

Myror, who noticed the camera flash at the same time as Nimueh, edged closer to the wall, his hands tightening around the hilt of his blades in anticipation, when something launched from behind the wall and landed at his feet. He barely had time to acknowledge the grenade before it exploded, throwing him back against a nearby archway and drawing the Nazis' attention away from Nimueh, now floating three feet off the ground like a marionette.

The ally soldiers ran in guns blazing, barely giving the Nazi troops time to react. Gaius made his way towards Nimueh, hoping to find a way to disable the machine before it was too late. He tumbled to the ground when a sharp pain shot through his leg, and it didn't take a medic to tell him that he'd been hit. He looked up at an old German general sneering down at him with his gun raised to deliver the killing shot and suddenly the general was lying on the ground, covered with bullet holes and Geoffrey and Odin were helping him to his feet.

"The portal…" he gasped against the pain.

"Will this stop it?" Odin asked, pulling a grenade out of a pouch hooked on his belt and handing it to Gaius.

All of a sudden, the sergeant gasped out in surprise, and a large blade stuck out his chest. Releasing their hold on him, Geoffrey and Gaius turned to see Myror standing behind them, his blade red with Odin's blood and the other raised to finish them off next.

Gaius stared down Myror, unafraid of whatever terrible death he had planned. To the assassin's surprise, the young professor pulled the pin on Odin's grenade and tossed it towards the open portal, grinning as it to slide underneath.

Forgetting about the cocky professor and the terrified soldier, he ran to the portal and slid under it as far as he could, his fingers just out of reach of the explosive. The ruins lit up as the portal went down in a cascade of flames, throwing Myror out of sight.

Gaius watched as Nimueh writhed and jerked in the air, the gantlet ripping her apart until her howls of pain were only echoes and the gantlet a piece of rumpled up gold. The soldiers let out a cheer of victory, but Gaius frowned and bit his lip in concern.

"What's wrong, Gaius? We closed the portal!" Geoffrey cheered.

"Yes," Gaius nodded. "But it was open to our world for too long. Something may have come through. We need to look around to be sure."

Geoffrey relayed the warning to the other men, who began searching the abbey while he helped Gaius limp into a small chamber to look at his leg.

Geoffrey froze at every sound while he wrapped Gaius' leg up. "Do you believe in hell?" he asked in a shaky voice.

Gaius sighed. "There is a place -a dark place where evil slumbers and awaits to return. From there it infects our dreams, our thoughts. Nimueh gave us a glance of that world tonight."

"Nimueh? That pretty lady?"

Gaius nodded and opened his mouth to say more, but a loud squeak sounded in the chamber, causing Geoffrey to jump back. "What was that?"

Gaius glanced at the ledge around the ceiling of the small chamber, his eyes finally landing on a small figure curled up in the corner. Geoffrey saw it too and drew his gun, letting loose a shot. The figure screeched like a bird and scurried over to one of the other corners. Geoffrey moved his gun towards it again, but Gaius held his hand out.

"No!" he whispered as the rest of the squad filed in, hearing the gunshot. "He's frightened."

Gaius reached into his pack and pulled out a bar of chocolate he had stashed away, slowly unwrapping it and holding it up towards the figure. "Are you hungry? Would you like some food?"

The figure slowly raised its head to reveal two bright gold eyes in the shadows. Gaius took a bite from the bar to show it was safe and held it back up, smiling as the figure inched forward.

Quick as it could, the bar was snatched from Gaius' hand and devoured it in seconds. Gaius pulled another bar from his bag, whispering for one of the men to grab a blanket. Geoffrey handed him a large wool blanket from his pack and Gaius held the new bar of chocolate up to the figure.

"I have more, but you're going to have to come down if you want it." He placed the chocolate bar in the blanket and held it out like a net. The figure crawled to the edge carefully before finally making its decision and jumping down into Gaius' arms, allowing them all to get a better look at him. Gaius' face lit up with joy.

"It's a boy." He whispered. "A baby boy."

He was small, about the size of a four year old child, with short black hair and ears that were adorably big. He almost could've passed off for a human child, except the outer edges of his skin were fiery red, and his eyes a vivid gold. Gaius knew at once that he was the child of a demon, a creature from the other world, and that they should kill him while they had the chance. But then, he looked into his eyes and saw so much goodness, and light and love that when the little demon smiled up at him, Gaius fell in love.

"What do we do with it?" Geoffrey asked, looking at him from over Gaius' shoulder.

Gaius bundled the demon in the blanket and held him tight. "I'm going to raise him."

"What are you going to call him?"

Gaius thought for a moment and smiled. "Merlin."

And from that point on, Gaius was a father. The American Government adopted the demon and put him under Gaius charge, on the condition that he live in a government facility and his existence never be known to the public.

And so A.L.B.I.O.N was born, and there Merlin sits to this day; the U.S Government's biggest secret.

A/N Hi! Hope you enjoyed the little teaser. Now, some of you are probably going to be like 'Why did he call him Merlin? That doesn't make sense.'

Maybe he just likes the name 'Merlin', have you thought of that? Not everything needs a reason.

Reviews are love, please tell me if you like it. I will update probably Tuesday or Wednesday even though I already have the chapter written, I want to get a little further ahead before I post Chapter 1, so I'll see you then!

Thank you for reading!

(Also, P.S, if you see any spelling, grammatical or repeating mistakes, by all means tell me because I do not have a beta)
