Chapter I: One Bad Day.

A six year old boy, named Harry Potter is trapped in a dark room of unknown. His limbs were painfully bound with chains and he could almost taste the air which is damp and filthy from his own perspiration and urine. He dared to make a single move and sound as his once innocent green eyes were wide in fear, taking the horrors surrounds him. His auntie Petunia laughs hysterically on the floor. Eyes rolling to the back of her head, no sound came from her but the hoarse sound of insanity hairs sprawled on the dirty floors which is tainted with the dried blood of uncle Vernon, who lie on a heap. His fresh wounds were now sealed with stitches, two gaping holes in the chest and a curved violent gash on the belly. A sick smiley face was violently carved on his body.

The door on the far corner slams open and a tall, pale and slender figure walk casually. The young boy could hear his cousin Dudley who was trying to hide into the shadows, the bigger boy was sobbing quietly as possible. Harry couldn't blame him. If he had the strength he would do the same. It was the monster in shape of a man, laughing madly, dressed in cheap purple suit and a top hat. It was the clown prince of crime and genocide. The Joker.

The dull light flickers several times, obscuring the face of the Joker. Finally stopping in front of Harry the Joker leaned closer, allowing the boy to see clearly the permanent grinning face of his worst nightmare. The fearful green orbs held the stare of the mad green ones that glowed with malicious glint, this moment will forever haunt the young boy.

"Oh Harry, stop squirming we're going to have so mucchhhhh fun instead! Best seat on the house and with popcorns too! WAHAHAhaha! Oh and I'm sure small D here will entertain us, right Pet? Vernie?"

And they shall watch the world burn.

"Wand?"

"Check"

"Books"

"Check"

"Uniform?"

"Check"

"Phone?"

"Check"

"Alfred?"

"Che- What the… where is he?" It was the Elven year old Harry Potter now known to the world as Harry Wayne, son of one of the richest man on the earth. He has an average height for his age, his lean but strong build is very noticeable with his cargo pants and a plain white shirts. He has a healthy tan skin and vibrant green eyes. His short black hair was swept to one side effectively concealing his jagged scar which was shaped like a lightning bolt. The young boy was getting a continued stream of appraising looks from the young girls and a jealous looks from boys of all age. He also received a disgusted sneer from a young blonde boy, who after meeting his gaze, continued on his way. All of this was ignore as Harry try to find his familiar. Worry is written on his face.

"What did I tell you about letting that cat out of your sight?" The second voice belongs to Zatanna Zatara, She a tall woman who was very beautiful and charming. She had a long- raven curls that almost reaches her waist. Cool blue eyes which held the same worry that Harry's has. She wore a white tube that proudly shows her well defined curves, black magician's jacket and black skinny jeans. She too, had received a good amount of appraising looks from men at the station. Zatanna check her pocket watch and bit back a curse. "Only a half hour left, we need to find him fast."

"Woof" A large black dog tackled Harry causing him to stumble slightly. It was his godfather Sirius Black in his animagus form.

"Padfoot!"

"Zanna, Harry" Zatanna and Harry both turned to the one and only Bruce Wayne. His aristocratic features and muscular built was recognized by almost everyone in station. On his arms is a dark tabby cat is resting comfortably, the feline basically meld with the expensive suit of Harry's father. "Looking for this?"

"Dad!" the boy, obviously delighted took his familiar and began to pet it. Alfred then jump beside Zatanna after the few seconds of attention. "You got Alfred."

"Where have you two been?" Zatanna inquire.

Bruce shrugged. "Padfoot want to walk with me before Harry go to school" the man knelt and pulled his son to hug in which the boy happily return.

Bruce whispers softly in his ear. "Sirius's connections said that some of those Dementors are still around the village near your school, I trust you learn from your charm activity with your teacher, Zanna"

Harry pulled away, smiling at his father before giving a confident nod.

"That's my boy" Bruce once again, pulled Harry into another hug before Alfred the cat meow softly, gaining the attention of the small group. "I guess it's time to go now, got everything you need?"

"I'll be fine, tell Dick, Jason, Tim, Damian, Alfred, Barbara that I will miss them."

"You should message them and your friends at the league that will keep them away from bugging me."

"I will Dad, I got my phone." The boy grinned.

Zatanna leaned forward and give her favorite and only student a kiss on forehead before ruffling the boy's hair. They were very close to each other in fact her relationship towards Harry can be compared to those of a mother and child. "Have fun Harry, no dueling at the hallways, make friends and maybe date some girls."

"WOOF! WOOF!"

"ZANNA! PADFOOT!"

The adults chuckled at Harry's flustered reaction, on Padfoot's case he let out a series of deep rumble. They look up when a magically enhanced voice inform the passengers that the students only have fifteen minutes to board the train.

Padfoot bump Harry with his large head before trying his best to hug his godson in his dog form. "I'll miss you too Padfoot."

"And please act like a dog." The said dog pounced then proceed licking his cheeks. "That's too much."

"Woof"

"Take care, Harry. See you in Christmas." Harry nodded before pulling Zatanna in a tight hug. The magician smiled as Harry squeezes her.

"I will"

Bruce put his hand on the boy's shoulder. "Be safe, Harry"

"Bye Dad. I love you"

Scooping up his familiar. the boy board the train without looking back at his father, Zatanna and Sirius. Just walking away from them was hard, it hurt him inside with every step he take. His excitement to learn magic at the school of Sirius and his biological parents were replaced with sadness and agony of leaving his family. Reality began to hit him. Hard. He won't see his friends from the league, he won't see Zatanna the closest women he had for a mother, he won't see Sirius or hear his jokes and stories about his time at Hogwarts, stories about James and Lily or his bark like laugh, he won't see his brothers, he will surely miss Dick's affection and Tim's muttering behind the bat computer, even Jason's unique sassiness or Damian's cocky and offending quips. Nothing will come close to Alfred Pennyworth's cooking and sarcasm and then there is his father. Father. Bruce Wayne is his father no matter who is his real parent is, his salvation on his dark past. He saved him from the Joker. He saved him from the Dursleys. He saved him from being an orphan. He fed him, he gave him clothes, he gave him family, he gave him home, he gave him love and for that, Harry is forever grateful.

He knows that his father didn't approve of his decision to go abroad. He was almost feel ashamed that he convince him and making his Dad to see another son to leave, Harry was aware to the story between his brothers and his father. The birds always flew away from the bat to prove and rediscover themselves.

"Meow?" Alfred the cat, bunt Harry's chest with his head, a way to express his affection. Harry smiled at the comfort the he receive from the gesture. The black tabby was a gift he received from Zanna, she said that the cat was his reward for learning the Patronus charm and according to her it is a tradition at Hogwarts that each student may have a familiar once they reach the age of eleven. The famous magician also give showed him a trick that will transfigure his familiar into a ferocious feline where he needed an extra claws and teeth. This causes the two to bond magically, Alfred's eye color turn to the same emerald green of Harry's. The boy smiled fondly. He remember naming the cat after Pennyworth, when Damian became annoyed and complained the tabby always seems to appeared whenever Robin tried to sneak out, much like their butler.

"Let's go buddy. Our adventure begins"

Harry found an almost empty compartment at the last car. Its only occupant is a lone girl who has a blonde hair which is tied in a bum, a fair complexion with a pinkish twinge. Her grassy green eyes were fixed on a textbook that Harry recognizes as a first year text book about potions. That means we're on the same year.

"Hello I'm Harry Wayne" Harry offered a polite smile as she peered on him. "Can I sit here?"

The girl looked up from her book and gave him a calculating stare. It took several moments before the girl nodded.

"Ok then" The boy fully step inside before heaving his trunk with ease. He took his sit which was directly opposite to the girl. His familiar gave the room a slight sniff before deciding to settle on his master's lap. Harry was fidgeting his phone and he could tell that the girl eyed him with interest.

Several moments pass in a blur, the ride was silent besides the constant purring of Alfred the cat. Harry felt relaxed and serene, he certainly loved watching the view on the window side and then the compartment door slid open. There stood a boy with two larger kids who had a matching mean looks. The boy on the lead was pale and has blonde hair. Harry recognizes him immediately as the one who sneer on him earlier.

The boy gave Harry a pointed look before taking a sit next to the girl who scowled at the other blonde's direction. "What do you want Malfoy?"

"Saying hello to an old friend, Greengrass" the Malfoy-boy said with a smirk.

"We're not friends" The Greengrass-girl said, eyes flashing dangerously.

The blonde boy blush slightly before his adopting a frown and saying on more business-like tone "Your life at Hogwarts will go a long way if we join forces you know"

"I think I'll just do fine. Now go before I hex you" the refuse the offer in icy voice.

Malfoy taken aback clearly not used to the girl's treatment, he looked around the compartment to compose himself. His eyes landed on Harry's whom he gave a nasty look, his lips twitch into a sneer of pure distaste. "I didn't know you're consorting with a mudblood Greengrass, You and your family is a disgrace to the purebloods for mixing with wrong sorts"

Harry had heard from Sirius that the magical Britain had a bad reputation because some families are prejudicial when it comes to heritage. For them, muggles and muggleborn are always beneath them because they lack the 'purity' in blood. He just not realized how bad it is upon encountering the Malfoy-boy who seems to think that he is a muggleborn because of his clothes.

Harry was about to interfere but the Greengrass-girl rose to her feet, glaring daggers at the other blonde. "The wrong sorts? You mean like your coward Death Eater of a father who brought his way out Azkaban? And for your information I don't know him."

Malfoy was gob smacked; it took him three flat seconds before his face turn to a full snarl. He raised his hand ready to hit the girl. Harry quickly climbed to his feet sending Alfred to the floor. He put himself between the blondes before things get worse. "I think you should just leave. No one wants you here."

"Listen to me yank. Don't you dare to interfere with me you filthy mudblood, I'm a Malfoy and you will respect me while you walk in my country!"

"Isn't Malfoy French? Mal-foi? Malicious Faith?" Harry said smartly, he fought a little to suppress a grin while the girl on his back cocked an eyebrow. Malfoy look even more upset, the large boy on his left looked confuse while the other actually let out a snicker which was quickly silence when the blonde boy glared on him. Harry could feel his cat tense, ready to pounce in action.

"Leave" It was The Greengrass-girl. Her voice was firm, demanding obedience.

"This isn't over." Malfoy tried to recover by holding his head. "You will regret this Greengrass you and your mudblood friend" They all left.

Harry slid the door shut before letting out a long sigh. Alfred bunted on his legs to show his worry for his master. He smiled fondly before taking his cat to his chest.

"Are you ok?" He asked the Greengrass-girl who gave him a curt nod. Her eyes relayed the unspoken thanks to him.

The city of Gotham exploded with chaos. A hospital and its nearby establishment set ablaze, hundreds injured, thousands of dead, millions of property destroyed. The police shot a boy over confusion and the inmates of the Arkham Asylum run rampant they lay waste on everything they set their eyes with.

Harry Potter was never been this afraid on his life. He and the Joker were both sitting on the couch that overlooked the city.

The Joker stands causing the boy to flinch. He let out a long sigh of contempt before saying "This might be my finest work yet"

"Stay here boy, Uncle J have some more to kill before the bats swoops in."

A/N: I originally plan to post this chapter on the middle of the month but due to some complications, I decided to delay and fix this chapter. I want to say sorry for this short chapter but I plan to edit everything once I got more time.

There are several things that I want to point out. Each chapter might contain some titbits regarding to Harry's past and things that happened around the wizarding world, I might introduce or reintroduce some character that will play an important role in the future. Several events will be altered greatly to avoid the repetitive fanfics of year one to year seven. I intend to create a contradiction between purebloods regarding their beliefs on their purity and interest on muggles. You might notice this above when Draco and Daphne were interacting.
