Chapter 1

Legendary pokemon are rare.

So rare in fact that some of them disguise themselves as humans and have a child with another human so that they may have children.

This story is about one certain child by the name of Harry Potter. Otherwise known as the son of Xerneas.

Xerneas had run into Lily when he had traveled to another dimension for the day, and he fell in love with her. Two years later, Lily gave birth to Harry Potter. Xerneas loved his son but sensed that something dangerous was coming. Something that he couldn't stop.

Xerneas was sitting with Lily on the couch, reading a book, when it happened. The door was literally blasted open. The two adults stood up and Xerneas told Lily to run and get Harry while he held him off.

Xerneas faced off against Voldemort but try as he might, he could do nothing as the man shot a killing curse at him. The next thing Xerneas knew, the world was fading into blackness.

Several hours later, Xerneas woke up. He looked around but no one was there. He suddenly remembered what happened and ran upstairs. He found the body of Lily and knew she was dead. The only question was, where was Harry?

After countless hours of searching, Xerneas still couldn't find Harry. But he would never stop looking, never. It was his job as a father to find his son.

Three years later...

Harry winced as his arm fell against his side. His uncle had broken it and thrown him into his cupboard. Now the four year old was crying silently on his bed, his pale blonde hair with multicolored tips totally messed up. He wondered what he had done that would make his parents leave him with his aunt and uncle.

Meanwhile, Mew had just teleported to Xerneas's side. The legendary pokemon had finally found Harry Potter but he wasn't in the best of condition.

"Xerneas!" Mew exclaimed as soon as he appeared.

"Mew! What is it?" Xerneas asked.

"I found him. I found Harry." Mew replied and Xerneas's eyes widened in shock. Before he could say anything though, Mew said. "But Xerneas, he's not exactly healthy."

"What do you mean?" Xerneas asked, his eyes narrowing.

Mew took a deep breath and then he asked.

"Did Harry's mother ever tell you about someone named Petunia Dursley?"

That was when Xerneas exploded with rage. His son was with Petunia Dursley, a woman who hated anything to do with magic including her own sister.

"Where is he?" Xerneas growled.

"Back in the wizarding world, Little Whinging, Privet Drive, number 4." Mew replied taken aback a little.

Xerneas instantly disguised himself as a human and teleported to the house. He marched up the front lawn and slammed the door open, effectively startling everyone in the house.

"Where is he, where is Harry Potter?" Xerneas demanded growling.

"What do you want with him? Get out of here!" The man yelled at him.

"I won't leave until you give him to me." Xerneas growled.

The woman who had been trembling ran to the cupboard and pulled out a small boy who certainly didn't look four years old. She shoved him at Xerneas and the small boy stumbled as he collided with Xerneas. He looked a little scared when he looked up at Xerneas but Xerneas gave him a small smile and the child relaxed.

"Take him and leave!" The woman said.

Xerneas wanted to blast them so badly, but instead he picked up Harry and teleported back to his world.

When he reappeared in the forest, he gently sat Harry down onto the ground and transformed into his true self. Harry instantly scrambled back in fear.

"Don't be afraid, my child, you are safe here." Xerneas said gently. He hoped that Harry remembered his form from when he had shown his son it.

Harry stared at him for a moment before he asked.

"Papa?"

Xerneas smiled and softly nuzzled the child. Harry collasped crying onto his neck.

"Papa, where did you go? Where?" Harry asked still crying.

"I'm sorry, my little one, I lost you for a little while. But I am back now, and I promise that I will take care of you." Xerneas said laying down on the grass.

Harry nodded and after a minute, he sniffled and said.

"I thought that you didn't love me."

"Oh little one, I will always love you, now matter what." Xerneas said soothingly. "And your mother will as well."

"Papa, where is mama?" Harry asked turning his head as he looked for his mother.

Xerneas frowned for a moment and then he said softly.

"Mama had to leave, little one, but she loved you very much."

To Xerneas's surprise, Harry did not cry out for his mother, instead he just snuggled against his father's side with tears pouring down his cheeks as if he knew what had actually happened to his mother.

That was when Xerneas saw the lightning bolt scar on Harry's forehead. The legendary pokemon was about to ask where Harry had gotten it, but the child had fallen asleep. Sighing, Xerneas curled around his son and fell asleep as well.
