Bruce walked down the same hallway the next morning, putting on his under armor suit. He entered the main cabin to find his bat suit folded up on his chair, his invisibility cloak and chest piece hung on a spare manakin, usually used for his normal uniform. The sun glaring through the windows caused him to squint to find his breakfast, a plate of scrambled eggs, a side of bacon and a protein shake, on the counter.
"Master Wayne, I didn't expect you to be up this early." Alfred said as he walked in.
"Well, I like to get an early start on my day." Bruce grinned.
"All the modification on the Bat Car are finished." Alfred confirmed.
"We're seriously calling it that?" Bruce chuckled.
"Well, you have everything but a Bat Car so I thought I should get you one." Alfred joked.
After twenty minutes to eat and dawn his uniform, Batman walked outside.
"Are you sure they're aren't any press around here?" Batman asked.
"I asked the police to seal off the area to ensure your privacy." Alfred assured.
"Good, thank you Alfred, but I have a wizard to catch." Batman said as he walked up to the Bat Car. "I have to say, you outdid yourself, Alfred."
The rusty, light blue car was replaced with a sleek black one with stainless windows, shiny rims and two black fins on the back.
"Thank you, sir." Alfred smiled as Batman sat down in the driver's seat.
The car started by itself as Batman shut the door. He pulled back the gear and the car took to the sky and turned invisible with the press of a button.
As he flew over the city, he pulled out his phone and tried to activate the tracker he had placed on the case before the thug had gotten away. It kept failing to connect, but the car lurched to the right, as if it knew where Batman wanted to go.
Soon, they were flying over green, hilly countryside, a train track running alongside a large lake below. Clouds began to roll in and soon, he was in a gray fog, but the car flew on, the newly installed lights shining forwards into the darkness. After half an hour flying through the mist, the clouds opened up and he could see a huge castle, or at least what remained of it, on the lake side. Large clouds of smoke was spiraling up from it and there were holes on all of the four main towers.
Suddenly, his phone buzzed as the tracker icon appeared on his map.
"The case is in the tallest tower to the back right." He said out loud to get a few clicks in reply and car veered towards the tallest tower.
As he flew over the castle, he noticed a large standoff between two forces in the open pavilion. Death Eaters and a few other groups were facing off against what seemed to be the residents of the former fortress. He looked back up to see they were nearing the tower and he could see one black cloaked figure on a balcony holding what seemed to be a bow and arrow.
"Take us up, I need the drop on him." He ordered and the car complied.
They rose in elevation until they were hovering about twenty feet above the tower. Opening the door and tying a cable to the hook on the bottom of the chair for elevated drops, he readied his grappling gun.
He won't see me coming He thought to himself and his cloak turned invisible, everything but his head being completely gone.
"Stay here and wait for me." He told the car as he pulled the hood over his mask and began to quickly lower himself using the cable.
Arkayus readied his bow, the arrow tips being a vial of the Joker Toxin, aiming for the students of Hogwarts when he thought he heard something above him. Lowering his bow, he looked up, only to see nothing. He looked back at the crowd below him when he got kicked in the back of the head. He went tumbling into the room where the balcony was connected to as Batman's invisibility wore off.
"You." Arkayus laughed as he struggled to his feet. "I was wondering when you'd come back."
"I have a friend who's an archer, but he prefers green." Batman informed as he stepped into the room.
"I doubt he's as good as me." Arkayus taunted.
Arkayus whipped out his wand and fired a small lightning bolt and it got Batman in the chestplate and was thrown back, but got up again.
"What, how?" Arkayus gasped.
Batman leaped at him, grabbing the wand. They both struggle for possession as they traded blows, Batman punching Arkayus in the mask while Arkayus got a few shots into Batman's stomach. Finally, the wand went flying out of their hands and over the balcony, tumbling onto a ledge far below.
Arkayus kicked Batman back and grabbed the bow and arrow and fired it at Batman, only for Batman to catch it mid flight. Arkayus whipped out a knife and swung at him narrowly missing Batman's neck. Batman grabbed Arkayus' wrist and squeezed, getting a pressure point, causing the Death Eater to drop it.
Batman pushed him back, but Arkayus tripped on a pile of books and fell on his quiver which had swung forwards from his back to his side, holding thirteen of the Toxin arrows. All the vials broke, most of the poison going through Arkayus' mouth hole in his dragon mask. He coughed and shook violently.
"Batmaa-ack!" He sputtered, the glass he had landed on tearing through his cloak and getting blood everywhere.
Batman stood back, unsure of what to do until Arkayus finally stopped shaking and laid still. He stepped onto the balcony again and took out his binoculars and stared down at the courtyard. The two forces were still facing off, but some of the residents of the castle seemed to be surrendering to the Death Eaters.
"I have to help them." Batman told himself and ran through the room to a spiral staircase and began to run down. Back in the room, Arkayus shuddered and rose to his feet, removing his mask and hood. His dark skin was already losing color and turning chalk white, his brown hair paling and turning an unnatural shade of green.
"Batman…" He wondered aloud, smiling. "We aren't done yet."
Batman reached the bottom of the stairs and ran through corridors and hallways, some parts of the ceiling broken, the paintings on the wall torn or burning. He reached a junction where the hallway split in two. Suddenly, three orbs of black smoke flew down from the ceiling way above and landed on the left, right and behind him and solidified into Death Eaters
"So we really want to do this?" Batman asked.
"AVADACADAVERA!" One yelled and a green fireball launched from his wand and hit Batman in the stomach.
Batman sunk to one knee with a groan but quickly got his gun out and fired an array of sparks into the first, sending the Death Eater flying into a decorative suit of armor and crumpling to the floor. The second and third wizards pulled out swords from within their cloaks and rushed at Batman. He kicked the one in front of him and sidestepped the one charging at him from behind and punched him in the mask, making him stumbled back.
He turned and ducked, nearly being beheaded by the second Death Eater. He looked up and karate chopped the wizard's neck, causing him to drop his swords and clutch his neck, trying to get air. Batman sprayed a bottle of mist in his face and he collapsed. The one behind him left at him, but Batman caught him and whirled around, sending the Death Eater flying into a marble pillar.
Batman continued to run through the never ending maze of hallways and chambers and finally ending up in a classroom having a ninth story window. The army of Death Eaters looked ready to destroy what looked like students of this building.
"Batman!" He heard someone call behind him.
He was grabbed by the shoulders and thrown back into the hallway. Arkayus stood over him, but he didn't look the same. His dragon mask was gone and his face was white and hair green.
"Look what I have!" He laughed and pulled a vial of green liquid out from under his robes. "If you want to stop me from shooting this into a crowd of innocent students, you're going to have to catch me!"
Batman lunged at him, but Arkayus deformed into black smoke and flew up a flight of stairs, laughing as he flew. Batman grapple gunned a stone a few stories above him and flew upwards, the black smoke flying above him. He ascended six floors until Arkayus turned down a hallway, so Batman let go of his gun and hopped onto the floor and ran after him. He found Arkayus aiming the bow at the crowd, standing on another balcony.
"Too late, Batsy!" Arkayus cackled as he was about to let the arrow fly.
Too far away, Batman pulled out the magic pistol and fired. The sparks shot through the air and hit Arkayus in the shoulder. Arkayus flew off the balcony and dropped the arrow. Batman leaped and caught the arrow in one hand, while using his second grapple gun and firing the hook downwards, snagging Arkayus' cloak and hauling him back up. He hung the cord around a gargoyle and let Arkayus hang there for a second and pulled out his binoculars and looked down on the crowd. The Death Eaters were retreating and some white skinned wizard was wand fighting some kid.
"Can't you see it, Batman?" Arkayus chuckled. "We have won. Lord Voldemort prevails."
"You're insane, Arkayus." Batman informed him. "You've lost, it's over."
"Oh, it's definitely over." Arkayus told him. "Lord Voldemort has killed Harry Potter, and now that Voldemort has won, my services are no longer required."
"What are you talking about?" Batman questioned.
"Goodbye, Batman!" Arkayus cackled. "Always remember, I was the greatest magical enemy you have faced! Inferno!"
Arkayus pointed his wand at the cable he was tied to and it evaporated in smoke and he fell. Batman reached out but couldn't grab him as Arkayus tumbled downwards, laughing as he went until he landed on the rocks of the shore, 300 feet below.
Batman stayed there for a minute, his arm outstretched, staring at the dead body far below. He finally got up and held up his binoculars towards the courtyard. The white Death Eater had disappeared, and the lone student was all by himself.
The Bat Car, fully visible, pulled up next to the balcony and Batman hopped in.
"Bat Car, take me back to the docks." Batman panted.
As the car flew away, a tall red haired kid in the castle looked up and saw the car.
"Hermione, is that my old car?" He asked.
"Ron, you're probably seeing things." Hermione said as the car disappeared in the clouds.
Batman looked at the setting sun as the car flew over the clouds and leaned back in his chair and closed his eyes. He fell asleep as the car flew into sunset.
Back at the rocky shoreline, Arkayus' body began to bleed. The blood, poisoned with the Joker Toxin, began to seep into the mermaid infested lake as cheers of victory rose from the castle.
