Disclaimer: I don't own Harry Potter or Teen Titans

I'm not sure about the pairings yet but I think I'll stick to the canon ones for HP and I'll have RobStar and BBRae for TT, I don't know who to pair for Cyborg though.

This is my first Harry Potter and Teen Titans Xover. I'm sorry if the characters seems a bit OOC, it's a bit hard keeping them in character since it's been ages since I've watched them. Also I would like to point out that this happened after the movie 'Trouble in Tokyo' and at the beginning of "HP and the Order of the Phoenix". So this means that Raven already defeated Trigon and the rest would be explained in the story

If there are a few grammar errors please point it out to me since English is just my second language but I do live in England.

Chapter 1: Hogwarts New Student

(Titan's Tower)

The Titans just got home from their "vacation" in Tokyo, and as everybody knows Starfire and Robin are officially a couple - well everyone already knew that both had a thing for each other.

Everyone is doing their usual thing Cyborg and Beastboy playing video games, Starfire feeding silky, Robin training at the gym and Raven meditating at the rooftop but something seems to be off Raven is having trouble meditating which is weird because she never had trouble meditating before, so she concluded that she would be going inside her mind again.

She quickly teleported to her room and grabbed her meditating mirror and went inside to see what's wrong.

(Nevermore) - Raven's POV

Hmm... something's wrong here, Happy should have been here by now...

I better go find Knowledge and I better do it fast.

It's so quiet here, the only time that this ever happened is... *gasp* when Trigon is trying to take control, when Rage got fre and tried to consume me but I already beat Trigon and cast him away. He's locked up in the deepest pits of hell and only I can get him out of there.

I quickly ran to Rage's domain and its true, I saw Trigon and all of my other emotions are trying to beat him. This is bad if he takes control, the world might end yet again.

"RAGE SHALL CONSUME YOU!" he shouted. I quickly gathered all of my emotions once again and we all worked together as one, in a single strike we all worked up the power we have "Azarath Metrion ZINTHOS!" i shouted and white light in the form of a Raven shot out of my body and on to Trigon. Rage became my normal emotion again and Trigon lost his control over that emotion.

All the other emotions once again went back to their domains including Rage. Quickly going to Knowledge in hopes of finding out how that happened. "knowledge how did that happen, I have complete control over my emotions now even Rage" i said straight to the point "I don't know Raven, even I am confused by all of this, especially when Trigon appeared, I'll try to gather up as much information about this as I can and I think it would be safe if you meditate longer now" she answered

After that I left without a word.

(Titan's Tower common room)

Raven entered the room in her usual emotionless face. Beastboy's playing alone now since Cyborg went down to fix his 'baby'. Starfire and Robin are in a corner probably cuddling or making out.

"Hey Rae wan to play with me?" asked a very hyper Beastboy

"No, and my name is RAVEN" she answered in her monotone voice. Raven sat down and began to read her book when a tap can be heard on the window. There's an owl at the window which seems to be holding something. Raven using her powers made the owl come inside and the owl dropped a letter on the table. Raven seeing it was addressed to her immediately opened it, completely forgetting the fact that an owl delivered it which is definitely weird because you don't see an owl in broad daylight. The letter contents are:

HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY

Headmaster: Albus Dumbledore

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock, Supreme Mugwump, International Confed. of wizards)

Dear Ms. Roth

I am to inform you that a great threat in the wizarding world is in need of your assistance. A dark wizard known as Lord Voldemort with his fellow death eaters are causing havoc here. I have also heard that a powerful demon known as Trigon made a deal with him for reasons that are still unclear. I have heard that you posses great power that can help us greatly. If you are to accept helping us then please inform us as soon a possible and you will be attending Hogwarts.

Albus Dumbledore

'This is weird and I'm not even sure if I should believe it' thought Raven 'I'll ask the rest of the Titans about this'

"alright Raven what were you planning on saying to us?" asked Robin. Raven merely put the Letter on the table and Robin immediately read it. "So Raven what do you plan to do?"

"I'll accept because if Trigon is somehow involved in this mess, I need to know if he had escaped his prison already" Raven answered and as she said this the other titans' eyes widened.

"You're leaving Rae"

"Friend, I will greatly miss you"

"Are you sure?"

were what the other said and i just nodded and sent back a reply saying that I accept and the owl which was still there and it flew off.

On the rooftop Raven is meditating again when she sensed someone's there. She saw that it was Beastboy but he looked a bit sad which was weird since Beastboy hardly ever gets sad.

"Raven, how long would you be away?" he asked

"I'm not sure but I will probably back after the end of school"

"Rae?"

"Yes"

"I just wanted you to know that I would miss you, it just won't be the same without you here" he admitted but a slight blush on his cheeks

"I'll be back before you know it" Raven game him one of her smiles and hugged him. Raven blushed when she realised what she was doing and quickly pulled away. Beastboy left because he too was embarrassed.

Raven will be leaving in a few weeks time since she got back a reply that all of the things that she needs are already at hogwarts and doesn't need to buy anymore things. She went to Diagon Alley with Hagrid and got everything she needs. All she needs to bring is her things and she already got her set of robes delivered to her as well as her books and school supplies, this includes her ticket to Platform 9 3/4. She will be teleporting to the station so she doesn't need to worry about getting to England.

Raven is now in King Cross Station and is looking for the platform, she saw a few people walking through a wall, so she just followed them and she went on the train, she went in an empty compartment and read one of the books she brought.

A few minutes later three people went there and asked if they could sit there since all the others were full. Raven just gave a little nod and went back on reading her book. The three people better known as Harry Potter, Hermione Granger, and Ron Weasley. Raven didn't know their names of course and she didn't intend to know.

The Golden Trio was looking at the weird and slightly creepy girl in the compartment. Raven was wearing her usual leotard and cloak so they can't see her face. Hermione decided to befriend the girl. "Hello, are you new at Hogwarts, I never saw you before I'm Hermione, thats Ron and Harry" she said nicely and pointed at the two boys when she introduced them. Raven conclude that the people seems to be nice so she introduced herself "I'm Raven and yes I'm new here"

"Not to be rude or anything but aren't you too old to be a first year" Hermione smacked Ron when he said this. Raven just replied "I'm not a first year I'm a sixth year and I'm a transfer student from America" she answered without looking up the book she was reading. They couldn't help but notice that she talks in a monotone voice but didn't say anything because it's rude and it might offend her.

"I've never heard of any transfer students in Hogwarts before, Hermione how bout you?" Ron asked while rubbing a non existent beard.

"Me too but I guess Professor Dumbledore wanted to try something new as he he always does" Hermione answered but sounded a bit unsure.

"Stop it, she sitting right across us you know, she can hear us" Harry scolded to both of them because it is rude to talk about people. Ron and Hermione just sheepishly grinned at Harry but they muttered a quick sorry.

"So, Raven what house do you think you'll be in?" asked Hermione trying to start a conversation.

"I'm not sure since I don't know how they sort someone" answered Raven still not looking up her book but had the slightest but of interest in the topic which made Hermione a bit relieved since the tension is slowly going away.

"Well there are 4 houses you can be sorted in, Gryffindor, Huffflepuff, Ravenclaw or Slytherin. Gryffindor is for the most brave, Hufflepuff's for the most loyal, Ravenclaw's for the most wise and knowledgeable ans Slytherin is for the most cunn-"

"EVIL! Slytherins are evil bastards" RON cut in which caused Hermione to whack him across the head, no one noticed it but a Raven slightly paled more when he mentioned the word evil.

"-as I was saying Slytherin are for the most cunning. All three of us are in Gryffindor and we're also sixth years." Hermione finished and once again asked if she had any thoughts on what house she might be in. Raven just shrugged a bit but also asked "What do they do to sort you?"

"There's a Sorting Hat which looks into your mind and memories to see which house you are best at, usually everyone is sorted at their first years but since you're a transfer student I guess they would sort you along with them." Hermione answered. Raven didn't say anything anymore and she looks too absorbed in her thoughts.

This is bad Raven thought my mind isn't safe and it may hurt whoever tries to enter it, once someone's in my mind there is no guarantee that they would be safe and people would obviously start to wonder what's wrong with this 'Sorting Hat' as I conclude that it would start screaming out in pain as soon as it entered my mind.

Harry, Hermione and Ron continued on talking about their summer holiday and Raven still is in deep thought that she didn't notice that the train stopped and only to notice this when Hermione pointed it out.

There she can see Hagrid calling out the first years which is where she would be joining for the Sorting.

Once in the Great Hall the sorting ceremony began but a lot of people were whispering about Raven since she isn't wearing the school robes which Dumbledore allowed on her first day and he allowed her to wear her cloak under her robes.

"Today we have a transfer student joining our sixth year students, please come up to be sorted Miss Raven Roth" Dumbledore said once all the first years were sorted.

Raven walked up to the stool, to everyone's eyes she looks completely emotionless but Raven is actually nervous inside because she can't let the hat into her mind.

McGonagall put the hat on her head as soon as Raven sat on the stool.

You can't go into my mind, it isn't safe Raven immediately told the hat once it was on her head

How am I supposed to sort you then? You need to put down your barriers even in the slightest bit the sorting hat answered back

Don't say I didn't warn you Raven let the hat in a bit only to see Trigon, the hat nearly screamed from the pain that Rage/Trigon caused it but stopped because Raven immediately put up all her barriers completely again.

The hat shouted out "SLYTHERIN" but it seemed a little off to some people because it isn't as energetic as it usaully is it rather seemed a bit weak and terrified, and to be honest she already suspected it, she is evil probably even more evil than this Lord Voldemort ever became. She stood up and walked to the Slytherin table where the people applauded and Dumbledore started off his speech again which a pink toad cough-Umbridge-cough rudely interrupted and said a few words that's too sickly sweet for Raven's taste. After a few more words the feast began but when Raven was walking to the table a few people were gossiping about her and some even went pale just from her gaze.

At the Slytherin table a certain blonde, pureblood immediately introduced himself "Draco Malfoy, pureblood. What's you blood status? Pureblood or half-blood?"

Raven said neither which caused most of the people to gasp.

"Are you a mudblood then?" Draco sneered out as he said the word mudblood with pure disgust. Some people started to talk about Raven and her blood status because so far everyone thought she was a muggle-born but they never been sorted into Slytherin because it is a noble house for purebloods.

"No" Raven answered flatly which caused everyone to gasp again.

"What are you then? a squib?" said Pansy while yanking off Raven's hood(she had it on the whole time, even at the train), her appearance caught all the tables attention as most people gasped(what's with the gasps) and some were confused.

"No, and don't you dare touch me or it will be the last thing you'll ever do" Raven sneered at Pansy who was still in her shocked state. Everyone immediately backed off from Raven once she spoke and everyone avoided her glare. Draco however still wanted to know her status is and asked rudely "What the hell are you then?"

Raven finally losing her temper, put her hood back up which shocked everyone again as a black aura of magic pulled her hood back up and then she put her head down quietly saying her mantra before she loses control. A random boy on the table shouted "Are you crying bitch? can't tell us what you really are?"

This caused Raven to snap and when she looked up everyone paled at the sight of Raven and some people even fainted because facing everyone is the four blood red eyes of the demonic form of Raven. All the plates shattered which caught the attention of the whole hall. Raven grew up in size and had tentacles under her cloak. She grabbed the boy that called her a bitch and started dragging him down. Everybody was terrified at this point even Dumbledore had a hint of fear in his eyes.

"WHAT'S THE MATTER? AFRAID OF THE DARK?" Raven said in a demonic voice and everyone was cowering at that point but a boy who who just entered the hall shouted her name which caused her to let out a shocked gasp before fainting.

The boy who shouted her name was weirdly green, which nobody seemed to care about because everyone was still petrified in their seats and Raven was carried the boy her to the medical wing.

Dumbledore finally decided to speak up as he cleared his throat and everyone looked up at him and all had a questioning gaze at him some still haven't overcome their shock and fear.

"Harry Potter, Ron Weasley and Hermione Granger please go to the medical room please" he started and the said students left.

Dumbledore raised his wand up and shouted 'obliviate' and erased all the people in the hall's memory of the what happened in the past few minutes which was good because Umbridge planned on calling the ministry.

Everyone acted like nothing happened and he stood up and excused himself. He went to the medical room where he would start asking questions while wondering if his choice on asking Raven for help was a good idea. He was sure that he made up the right mind to also call up her friend Beastboy to accompany he in case something happens to her he would know what to do.

He entered the room and...
