A/N: Sup, Players? Look this is my second crossover and I honestly don't know everything there is to know about Harry Potter, so if I get something wrong, warn me. Although I know a great deal about Teen Titans. This is set basically during the Order of the Phoenix and before The End. Anyhow:

Sirius has asked Harry to accompany him and Dumbledore in Jump City, California. Harry, although suspicious, agrees and tells Hermione and Ron where he's going. When he and Sirius meet up with Dumbledore, who had left earlier than necessary to check on something, at a Pizza Place, they notice a group of ex-Slytherins (the already graduated type) and decide to follow them. When the Slytherins (or should I say death-eaters) attack a giant T the trio encounter Raven and the Teen Titans.

I'm working out the kinks.

Prologue: Part 1

Ron and Harry burst out laughing. Fred and George had just told them a hilarious joke but apparently they weren't supposed to know about it.

"Just don't tell anyone, okay? Mum and Dad would sacrifice us to a bloody dragon if they knew that we know that joke." The older wizards whispered to them, the four were already getting strange looks from the adults just from Ron and Harry laughing. They nodded and tried (unsuccessfully) to calm the laughter.

"What's so funny?" Hermione asked as she walked up to them, they were at the House of Black. The chuckling two quietened down.

"Nothing, nothing." Harry said waving his hand, as to dismiss the conversation. Hermione was obviously unconvinced and showed it well.

"Okay then, well, Sirius wants to talk to you Harry. He said he wanted to see you in the family tree room (didn't hear the name in the movie) straight away." Hermione then walked off, probably to go and play with Crookshanks or talk with Ginny. Ron, Fred and George stared at him.

"What do you think he wants?" Ron seemed curiously confused. Harry shrugged.

"Won't know until I go see." He stood up and walked to the huge circular room. As he walked he began guessing why his godfather wanted to see him. He didn't even notice that he'd walked straight past a mumbling Kreacher.

Death-eaters? No. Voldemort? Nope. When he got there the door was open and Sirius Black was standing in the centre of the room, back facing Harry. Said boy knocked after a few seconds and his godfather turned to him.

"Ah, Harry. I wanted to ask you something rather important." Sirius motioned for said boy to come closer.

"What is it, Sirius?" Harry did as (silently) told. Sirius used his wand to shut the door and then turned back to his godson, placing his hands on Harry's shoulders.

"Now Harry, I want you to come with Dumbledore and me to Jump City in America. We have some very important business there and it does involve you." Sirius whispered to him. Harry was slightly confused.

"I'd love to come but, Sirius, why does it concern me? And why America?" Harry's head was nearly swelled with questions. Sirius sighed and patted Harry's head for no apparent reason.

"You'll see soon enough, my boy." He then left but not before Harry noticed the despair in his eyes. The scarred boy was now overly confused. Why was Sirius so upset? Why did he ask Harry to go to America with him? Harry shook his head and retired for the night.

The next morning came quickly with the twins hilarious pranks on the adults. When the three were alone, Harry told Ron and Hermione what Sirius had asked him.

"That's bloody ridiculous! Why do you think he didn't tell you?" Ron was clad in a plain T-shirt and Jeans. Hermione, dressed in a simple long sleeved shirt and imitation jeans, glared at him.

"Why else you idiot? It will obviously have an enormous emotional effect on Harry!" Hermione's glare softened when she looked back at the raven haired boy. Harry simply looked at his two best friends.

"Guys . . . whatever Sirius isn't telling me obviously must have something to do with my parents. Why else would he have looked so distressed earlier?" Harry mumbled to them, he didn't want Fred and George to catch wind of their conversation yet. The other two nodded. Suddenly there was a knock on the door. The trio jumped and turned towards the door of Harry's room. Standing right at the door, was none other than . . .

"Harry, I think it's time we leave." . . . Sirius Black. Harry nodded and said his goodbyes. He and Sirius walked down to the kitchen, no one else was there. He offered his arm and together they apparated to Jump City.

When Harry opened his eyes he noticed that he and Sirius were in an alleyway. The animagus then led Harry to a Pizza Place. The lighting scarred boy had so many questions before he saw Dumbledore; then there were tons more. The elderly Hogwarts headmaster smiled and motioned to the seats at his table.

"Why do you think they listed mustard as a drink?" Albus questioned as Harry and Sirius sat down. The teenager just grabbed a spare menu that was on the table and looked in the drinks section, indeed mustard was listed as a beverage. Sirius just shrugged. He then grabbed another menu and hid behind it. Harry looked around and saw five death-eaters (in full uniform) strolling across the road. Harry sharply turned around and threw the hood of his jacket up.

"Why are they here!?" He hissed. Harry glanced back at them for a second . . . yep, definitely death-eaters.

"The same reason we are here, I would presume." Dumbledore said replied. Harry looked up at him, "We should follow them; they may just show us an opportunity not worth missing." Sirius nodded.

"Let's hope she's doing alright." Padfoot mumbled almost inaudibly. But Harry heard him.

The trio had discreetly followed the five death-eaters to an island with a giant building shaped like a 'T'.

"This gives a whole new meaning to saying 'to a T'." Sirius whispered to Harry who nodded. I mean a giant T? Gimme a break! The death-eaters then turned to their smoke forms and attacked.

One minute earlier.

Raven had been sitting in her room, staring at her violin case. Her grandmother gave her violin to her when she was young, saying it would be useful for the purification of the soul. Meaning that Raven should play it whenever she needed to express emotion. But it was no fun without Granny's piano playing. Just then she heard Starfire's (and possibly Beast-Boy's) screams; clashes, bangs and all sorts of noises associated with damage. Raven placed the occupied case on her bed and stood, ready to fight if necessary. Before she could do anything, the door started glowing green . . . then shattered into a million pieces. The pieces flew at her and Raven simply produced a shield to defend. Then a barrage of hexes, curses and other harmful spells hit the shield, although she couldn't see the faces of her attackers. Raven's powers depended on her emotions and her emotions depended on her mind. Raven's mind was delicate at that very moment. So you can guess why she wasn't surprised when the shield went down. Although she was very surprised when . . .
