There once was a prophecy, concerning the fall of a Dark Wizard Lord. It said that two boys, connected by mind and body, would defeat him. Unfortunately, the seer who delivered this prophecy wasn't a very good one, and the prophecy was misinterpreted;
The one with the power to vanquish the Dark Lord approaches…
Born to those who have thrice defied him, born as the seventh month dies…
And the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not…
And either must die at the hand of the other for neither can live while the other survives…
The one with the power to vanquish the Dark Lord will be born as the seventh month dies…
At this time the Wizarding World knew of three children who had been born on July 31st. Two twins to the Potter Family and a small boy to the Longbottom's. As the Light Wizards didn't know which family would be targeted, which child was the boy of the prophecy, Light Lord Dumbledore sent both families into hiding. Unfortunately, the Potters placed their trust in the wrong man and, on the Night of Halloween, the Dark Lord broke into their safe house while Lily and James Potter where round a friends party. The Dark Lord quickly killed the girl who was babysitting the two boys, Harry and Charles. Then he turned his wand on the two babies, staring innocently up at him. Deciding to kill the both of them, the Dark Lord first shot the killing curse at Harry.
A bright ball of sea-green light enveloped the baby, acting as a shield, and reflected the killing curse straight back to its caster. The only damage was a lightning shaped scar on the small boy's forehead. But even as it killed the Dark Lord, the killing curse exploded, sending rubble flying everywhere. It hit both the babies, cutting Charles across the cheek in a star shaped pattern and knocking Harry unconscious.
By the time Lily and James returned, their house was in ruins, but their babies were still safely lying in their cots, both sleeping peacefully.
This left the Light Wizards at a loss. Which boy was the boy of the prophecy? In the end Dumbledore told the press it was Charles, just to get them off his back, and it stuck. Harry was pushed back into the shadows, forgotten as his brother was shoved into the spotlight of fame, fame for a deed that he didn't do….
As the years when by Lily and James Potter started to neglect Harry more and more as they doted on Charles. Harry was a strange child, considered schizophrenic by most who spoke to him – not that many people did. For the first five years of his life he only ever saw his brother, parents, godfather (Severus Snape – an old school friend of Lily's) and his 'honorary uncles (Sirius Black and Remus Lupin – his dad's school friends and Charles' Godfathers.) But after his fifth or sixth birthday he stopped getting visitors. Severus had an argument with James and was banned from seeing Harry. Sirius and Remus slowly started leaving Harry out to spend more time with Charles.
So Harry spent five years of his life alone, forgotten by even his own family. But he wasn't completely alone. Harry was a rare conundrum. He shared his body with another soul. A soul of a Demigod, Perseus (as they had both decided to call him) or Percy for short.
It would appear the night Lily had gotten pregnant with Harry and Charles, she had also slept with one of the Greek Gods. Not that Harry and Percy knew what Percy was at the time, but the fact remained; he was a Demigod.
This was the reason the world seemed to think Harry was schizophrenic. Sometimes he was in control of their body and sometimes Percy was. Although their personalities were similar, the way they spoke, walked, ate and even carried themselves was vastly different to each other. Percy tended to be more politely spoken, and preferred exercise much more than the book-loving Harry did. On the other hand, Harry walked more upright and stiffly, unlike Percy who was in the habit of slouching.
And if anyone cared to look, not that anyone did, the green of the boys' eyes changed ever so slightly depending on who was in control. Harry's eyes were bright green, the colour of the killing curse. Percy's were a softer sea-green that seemed to draw people in – or they did when people used to be around to see them.
During their five years of solitude the boy's spent a lot of time either in the library or in the gym. Harry liked the library more than Percy, as (due to his godly heritage) Percy was dyslexic and ADHD, which sometimes even annoyed Harry when it got really bad. In the gym, however, Percy could spend hours working on his stamina at running or swimming, or learning martial arts or swordsmanship.
It was when they turned 11, however, that the two boys were suddenly shoved back into the real world…
