Author Note: I do not own Harry Potter or anything from the DC Universe. Also some of this story was inspired by the fanfiction Harry Isley. If you recognize something from my fanfic then I probably don't own it.

Summary: Harry Potter grew up abused with his relatives. But when he was on vacation in Gotham Harry once again became an orphan when his relatives were killed. Watch Harry growing up in Gotham under the care of Poison Ivy and during his time in and out of Hogwarts. (All Seven Years of Hogwarts and beyond. A Harry Potter/Barbara Gordon/Daphne Greengrass pairing.)

Harry's early years in Hogwarts and pre-Hogwarts years will be more of a summary with a lot of time skips until the story goes more in-depth when Harry is a bit older.

Warning: This story will be very AU so if you don't like the fact that I messed with the Harry Potter or DC Universe, you can read something else.

Chapter 1

Harry Potter was anything but a normal boy while growing up. In fact, Harry Potter was convinced that his relatives had it right when they told him that he was a freak. The reason for this was ever since Harry could remember he could make strange things happen. For instance one night after a particularly bad beating from the Dursleys when he was five years old, Harry discovered that he could use his hand to "will" the locks on his cupboard open so that he could get some bandages and food. Shortly after he made this discovery Harry found that he had some other amazing powers. For example, when he was six Harry discovered that he could levitate and summon things to himself. Moreover, when he was seven he learned how to teleport while running away from Dudley and his friends. However, even with all of these amazing powers Harry still had a difficult life living with the Dursleys, but all of that was about to change.

During the September after Harry's eight birthday, Harry found himself to be the most excited he could ever remember up to this point. The reason why he was excited? It was because the Dursleys were forced to take him with them on vacation to Gotham City in the United States. During the flight Harry was even allowed to watch a movie on the television and eat a whole meal. Of course, this may have only been because he was flying coach while the Dursleys were flying First Class. However, all to soon Harry found himself in Gotham City with the Dursleys on the way to the hotel which was near the famous Arkham Asylum.

Once they were at the hotel Uncle Vernon had Harry put everything away before the Dursleys decided to go out to dinner while leaving Harry in the hotel room. But with that being said, Harry couldn't have been happier. For once he had a relatively full stomach and he would even get to watch the television. Yet this good mood did not last for long once he turned on the news a little while later.

"This breaking news just came in," said a brunette reporter on the Channel 7 News, "it appears that the Joker has once again broke out of Arkham Asylum, hijacked a taxi, and is currently on the run from the both the Police and Batman. Unfortunately it seems that the Joker toke the lives of the four people inside the taxi, the names are Matthew Phillips, Vernon Dursley, Petunia Dursley, and Dudley Dursley. We will continue to keep you informed of any news on the current Joker situation."

At that moment only one thought entered Harry's mind. What do I do now?
