"Hey cats." Harley smirked at Selina Kyle, who was wearing her Catwoman outfit. The skin tight suit along with the goggles that looked like cat ears and all,

"What do you want Ivy?" Selina turns toward Ivy, igniting Harley for a moment.

"We need you to contact Batman for us." Ivy told her, her eyes watching Selina for her reaction.

"Why would I do that?" She hisses back at them.

"Because we need to make a deal with him." Harley tells her.

"What!?" Selina jumps up in confusion.

"You May have noticed how neither of us have ended up in Arkham already." Ivy tells her. "And we have no intention of going back."

"And how is Batman supposed to stop that from happening?"

"He isn't. Not directly anyway."

"We have a new charge. A kid." Ivy explained. "We met him a week ago, and yet we have already become attached to him. If we were to go to Arkham, we'd be abandoning him."

"The two of us have decided to try to be better." Harley told her. "No less crazy, but no more villain-like behavior."

"Really." Selina said deadpanned. She somehow doubted that they would manage to do that.

"We need to talk to Batman about not looking for us. And perhaps have him help us with our new ideas."

"I can see if I can contact him." Selina nods. "I can't promise that he will agree, but I can see."

"That's all I ask." Ivy nodded back.

12:00am

Gotham Rooftop

Harley Quinn and Poison Ivy watched the bat signal glow. Selina told them that Batman agreed to meet them, and they were watching every shadow so he couldn't sneak up on them.

"What do you want?" The Bat stated, causing them to jump in shock.

"Will you stop doing that!?" Harley shouted, clutching her heart.

"We need to make a deal." Ivy told him. "We are going to go good. We need you not to search for us."

Batman looked at them for a second, his white lenses blocking his eyes. "You have a kid."

"Yes." Harley nodded, unsurprised that Bats was able to figure it out. "And we need to raise him, Batsy."

Batman was conflicted, that much was obvious.

"And what would make me trust you? What would make me help you?"

"We will go clean for a year." Ivy tells him, "We will prove it to you."

"What will stop you from robbing a place for money?"

"I plan to start fighting for the environment on a more peaceful front. If I can prove that I am clean, I was hoping you could help me."

"How?"

"Not many people can afford your equipment Wayne." Ivy grinned at him. "And you are one of the leading industrialists. If you were to start making your buildings more eco friendly, you'd be helping my cause."

"Very well." The Bat stated, shocked that Ivy figured out his identity. "I will keep an eye on you, and the moment you go back to criminals I will arrest you. What about the kid's education?"

"I was thinking we could have some of the less violent villains teach him." Harley told him.

"Not happening." Wayne stated, with no room for disagreement in his voice. "I will pay for his tuition and he will go to Widow Creek Elementary. I need his name though."

"Sound's fair." Ivy told him, glad Harry wasn't to interact with the others. He was a good kid, there was no need to corrupt him.

"We have a deal?" Harley beamed at him,

"Yes." Bruce Wayne told them. "However, I will go farther. If you manage to stay clean, I will hire you two for my company. You can lead the charge to be green."

"Thank you Wayne. His name is Harry Potter" Ivy lightly grins, glancing at Harley. They heard a slight breeze and Batman was gone.

Headmaster's Office

Hogwarts School of Witchcraft and Wizardry

11:00am

"Good morning everyone." Albus Dumbledore greeted everyone as he sat at his desk.

"What is this about, Albus?" Alastor "Mad-Eye" Moody growled out. "I'm a busy man."

"I do apologize, Alastor." Albus nodded at him, his eyes twinkling. "I called this meeting about young Harry."

"Harry?" Remus Lupin sat up. "What's wrong with Harry?"

"The boy, along with his relatives, have gone missing."

"WHAT!?" Molly Weasley shouted. "How could you let this happen Albus!?"

"It was never my intention Molly." Albus calmly stated. "That's why I summoned this meeting. To find him."

"I should never have trusted you to do the right thing with Lily's son." Severus Snape growled. "We need to find him. Lupin, come with me."

"You are right." Remus said, standing up, determination on his face. "James, Lily, and Peter are dead. Sirius is in Azkaban. It's my duty to rescue him. And when I do, I will raise him. I failed my duty the first time, but not again."

"Lupin, If you could accompany me to the Dursley's residence, we can see if we can find any clues."

Albus just nodded sadly as he watched them leave.

Number 4 Privet Drive

Little Whinging, Surrey

11:05am

Two loud cracks were heard on the normally silent street. If Petunia Dursley were home, it would have brought her to the window. However, the two wizards went unnoticed. They silently unlocked the door to Number 4, as they slipped inside.

"Homenum Revelio." Remus cast, only for nothing to happen.

"You really think Albus would not have tried that?" Snape sneered.

The two walked around the house, noticing how clean the house was.

"How can anyone live like this?" Lupin questioned, only to receive a shrug in response. Then he saw the photos on the wall. None of them including Harry.

"This is his home, right?" Lupin questions Snape.

"Yes."

Closing his eyes, Remus starts to use his werewolf tracking skills to pick up on the scent he knows to be Harry's. Surprisingly however, it led him to a cupboard that was under the stairs. The cupboard had a single lock on the outside, which Lupin easily got through. However, he could not prepare himself for what he saw.

Inside was a small cot, clearly heavily slept in. There was dried blood on the sheets, and a little paper that had 'Harry's room' written on it. Remus's eyes flashed yellow in anger, as he shot off a Reducto curse at the wall.

Snape, his eyes not leaving the cupboard, repaired the wall with a flick of his wrist. He then cast a Patronus to Dumbledore, who seconds later apparated in. Looking at the cupboard, Albus knew his plans were falling apart. It was a mistake to use those who actually cared for the boy.

Obliviating the people he told was easy enough, he knew they trusted him too much. Harry's name was still written in the Book of Admittance, meaning he was still alive. He'll just have to wait for Harry's letter to be sent for him to find out where he is. Then he can start to mold the boy to be his weapon and sacrificial lamb. It was all for the Greater Good of course.

Gotham City

1 day later

After Harley somehow managed to burn water when attempting to cook, her, Ivy, and Harry were sitting eating fast food, when the lights flickered out.

Both the women immediately stood up, when they flicked back on and Batman stood there.

"What do you want, Batsy?" Harley glanced at Harry to make sure he was safe.

"Why did you not tell me the child was a Wizard?" Batman growled.

"A what?" Harry exclaimed.

"You don't know." Batman muttered, before pulling off his mask. "Forget the deal. As much as I hate to admit it, I have to trust you guys now. I have summoned Constantine and Zatanna to help me explain this. They will be along shortly."

"Long story, I guess." Harley sat down.

"Let me tell you a story of magic and war." Batman started, before telling them everything he knows.
