Chapter 1

"Boy!"

Harry looked up from his cleaning when he heard his uncle yelling for him. When Uncle Vernon came into the kitchen he didn't seem angry which was a big change for Harry.

"Yes uncle Vernon?" Harry asked, noticing the backpack in his Uncle's hands.

"I've got an important client coming over, the names Pegasus or something but that doesn't matter what does matter is that his into this Japanese Duel monsters game which you are going to let Dudley show off his duelling skills on you to impress Mister Pegasus, got it?" Vernon said with a glare.

"I am to lose a duel to Dudley in front of Mister Pegasus," Harry said, he should of known that he would always be worthless and Dudley would always be number one, he wondered if anyone would come and take him away to a loving family.

"Here," Vernon said as he shoved the backpack into Harry's arms "Go and make yourself a deck out of these cards Dudley didn't want. Be ready for seven tonight."

Watching his Uncle leave Harry went out into the garden and began to build his deck, not really noticing how some of the dragon cards seemed to be calling out to him.

***Time Skip to the end of the duel***

"You freak! You were supposed to lose!" Vernon yelled as he lost his temper and much to Petunias shock and Pegasus anger hit Harry causing Harry to fall face first into the nearby glass table.

Pegasus had seen enough, he pulled out his mobile, phoned for an ambulance then cradled Harry in his arms like a new born baby.

"Don't worry little one, no matter the reason why those dragon cards reacted the way they did I won't let anything happen to you," Pegasus said softly as there was soon sounds of sirens in the distance.

To be continued...

Okay guys this is the last challenge I adopted...or I think so...but this is only the prologue and not a proper chapter as I can't do action! Next chapter will have more in it and a time skip to duellist kingdom! Let's just say that Pegasus is going to fight for his son's eye sight!
