Story: Perseus and the Monster Force

AN: This is an alternative universe (AU) story that is a combination of the Greek and Roman pantheons. The hero in this story is named Perseus, but he will be quite different from Percy Jackson, except for his sea green eyes and raven black hair. This will not be a Percabeth story, although Annabeth will be in the story as well as all the other characters. Perseus will be an immortal, but not a god, at least not at first. He will be a mix of the pantheons, Greek and Roman. The first and second great prophecies will come into play here, except half-blood of the eldest gods will mean a child of Rome and Greece. A half-Greek and half-Roman immortal child; this will change Percy from the original stories. I won't go into more detail, but this story will be different and I plan on making it full of action, so stay tuned more to come.

Chapter 1: Beginnings

Yosemite National Park, California

A wolf the size of a grizzly bear ran through the forest. The night was young, but the wolf ran as if her life depended upon her speed or was it the little bundle that she held in her jaws protectively. She stopped running and panted quietly next to a large stone wall. The grey stone of the wall rose at a ninety degree angle from the forest floor. The wolf laid down her bundle; the small blankets it was made of began to move until the small hand of an infant was exposed. The wolf sniffed the hand before her golden eyes began to glow. The glow of her eyes extended to cover her body, until the light grew blindingly bright. The light ceased and in the place of the wolf stood a beautiful woman with gold eyes and shining black hair. She wore the silver outfit of a hunter, but she wasn't a hunter of Diana or Artemis. No, she was Lupa; the Mother of Rome.

Lupa reached down and picked up the child. The baby grabbed her finger and squeezed tightly causing the woman to pull out of the child's grip in pain. She used her other hand to pull back the blankets to look at the child. The baby's skin was tanned, which was odd for an infant. He had black hair that matched Lupas'. He opened his eyes making the Mother of Rome smile at the sight. The baby had the most beautiful sea green eyes; the eyes of his father. Lupa sighed before frowning as she looked at the rock wall behind her. She concentrated on the wall until a Greek symbol appeared; a triangle, the delta symbol.

Suddenly, a breeze whipped through the forest; the smell of sea salt evident in the cool air. A mist of water appeared before her. The water began to condense into the form of a man. He was well over six feet tall. His skin was tan with wrinkle lines around his eyes and mouth, like he smiled all the time. He had short black hair and a neatly trimmed beard. He wore a Hawaiian shirt and khaki shorts. On his feet were weather beaten and worn sandals made of a light tanned leather. His sea green eyes shone brightly matching those of the child.

"Poseidon," Lupa said. The name wasn't easy for her to say; Greek names were never easy. Lupa tried to frown at the sea god, but she couldn't. She still cared deeply for him, even though he had helped her break the most ancient of laws.

The sea god smiled at the Roman goddess. "Lupa, are you sure about this?" he asked worriedly.

Lupa sighed. "He can't stay with me. The pack would never accept a child, let alone a forbidden one," Lupa explained.

Poseidon's bright green eyes darkened. "He's my son too," he said.

Lupa's golden eyes darkened. She could see the sadness in his eyes. "He's our child. That's the problem. We made a mistake and I won't let this child pay the price," Lupa explained.

"What happened to the tough Roman goddess?" Poseidon said with just a hint of amusement.

Lupa growled. "She'll kick your salty butt, but my son… our son needs a home. He won't have that with me and certainly not with you and that terrible wife of yours," she exclaimed.

Poseidon nodded. Something about Lupa always warmed his blood and made him feel more alive than any woman he'd ever known before. It was most likely her wild side, the sea god mused. "I know," Poseidon said. "He'll hate both of us for leaving him."

Lupa looked down at the ground sadly. She hated feeling this way; she felt so weak. She took a few deep breaths before looking up to the man or god she loved. "We made a mistake. We have to own up to it," she said.

"I don't like it. He's one of her sons. How do you know he'll take care of him?" Poseidon asked desperately.

Lupa smiled at his concern. "He mourns for his own lost child. He's not beholden to his mother. He will help the boy grow and learn. He will make him strong," Lupa said.

"I really hope you're right," Poseidon said as he looked at the bundle in the goddess's arms

Lupa gave him a warm smile. Her pearly white canines shined in the moonlight. "I know I am," she said. "Would you like to hold him?"

Poseidon stepped closer until he was only a foot away from the Mother of Rome. Lupa placed the child wrapped in blankets into the god's waiting arms. Poseidon held the child carefully. The baby reached up and tugged on the god's beard. The strength of the child was amazing. Poseidon carefully pried the baby's hand from his beard. "That's one tough grip there son," he said.

Lupa's smile widened at the sight of her son with his father. "He has the strength of Rome," Lupa boasted.

Poseidon's crooked grin spread across his face. "He has the good looks of a Greek," Poseidon replied proudly. Lupa shook her head in amusement. "What did you name him?"

Lupa frowned at the question. "I haven't," she answered.

Poseidon's smile never left his face as he looked into his sons eyes; the eyes of the sea. "Don't worry; let his adoptive father name him. It seems only right," Poseidon reassured the goddess.

Lupa nodded. "Do you know how to bring him here?" Lupa questioned.

Poseidon leaned down and kissed the baby's cheek. "I love you son," he whispered. He turned back to the goddess with tears in his eyes. It was hard for the goddess to look at him. "I do."

Poseidon placed the child back into Lupa's arms. The sea god walked up to the stone wall and placed his hand over the delta symbol. His hand began to glow as he channeled his power through the stone. As the god of earthquakes he could use seismic waves to feel through rock and earth. He stretched out with his mind until he found the man he was looking for. He turned back toward Lupa. "He'll be here soon," Poseidon said.

"We better go," Lupa said.

Poseidon stepped closer to the goddess and rubbed his thumb across the baby's cheek. "Obey your new father child. I will be there when you need me," Poseidon said. He looked into Lupa's golden eyes. He leaned forward and kissed her tenderly. "I'll always love you my goddess." He smiled at her before disappearing into a fine mist.

Lupa had her eyes closed after he kissed her. When she opened them he was gone. She looked down at her son and sighed. "Grow up strong and proud, like a true Roman," she said. She kissed the child's forehead before laying him down on the ground just below the delta symbol. She stepped back away from her son; her body began to glow before she morphed into the giant wolf once again. The stone wall began to shift as the delta symbol began to glow. Lupa ran off into the woods.

The stone wall opened up into an entrance that was as tall as a man and twice as wide. A dark haired man with grey eyes stepped out of the entrance. He looked around until he heard the child whimper. He looked down at the bundle with wide eyes. He picked up the child and looked into the bundle. He gasped at the sight of the boy's sea green eyes.

"Who are you?" he whispered. He looked around for a note or something, but nothing was there. "Well, I can't leave you out here all alone, can I?" The baby smiled making the man smile in return. The child's smile reminded the man of his lost son.

The man sighed before stepping through the entrance. Before the doorway closed the man looked at the child once again. "I will call you Perseus," he said. "My name is Daedalus, and I'll be your father."

AN: I may not be updating this story very often until I get the others finished, but the poll results on my profile showed 50% in favor of a new story and not a sequel, so here it is.
