Hello guys, after a long personal debate and planning for almost a month. I have finally decided on a line up and title.

As the summary says, this fanfic will be a Harry Potter/Teen Titans crossover.

The version I will use for the Titans will be the Post-crisis and Pre-Flashpoint (sorry guys if you are not really a fan of the outside underwear) in short, New Earth. It will begin sometime after issue #100, meaning all stories is canon. As for Harry Potter, the timeline is canon up to Chamber of Secrets but with small alterations in the ancient past as well as the later books to fit it with this universe.

I am hoping it will be interesting to both fans of both universes and to crossover enthusiast, so will give it my best on this fanfiction. Please take some time to Rate and Review. It will help me with my story-making and English skills.

Disclaimer: Teen Titans and other DC characters belong to DC comics and Harry Potter belongs to J.K Rowling. I only own the slight alterations.

Without further Ado I present to you-

Harry Potter and the Gates of the Titans

Chapter 1: Welcome, Titans


A quiet night passes through the streets in downtown Gotham. But as everyone is to expect, the streets in Gotham are always more than meets the eye.

"Look I know it's Clayface, but isn't all of us a little bit of overkill even for someone tough like him?" Kid Flash asked Red Robin as the Teen Titans are watching from a rooftop of a tall building towards an abandoned warehouse near the port.

"I know, but from what I gathered he was hired to do those series of robbery from all those museums last week, that is why it was a clean job and only one specific item was stolen at each museum." Red Robin replied as he look using his binoculars to scout the area.

"True, but it still has to be worth something else rather than its value right?" Superboy asked as he looked towards the sea. Using his vision, he tries to spot any boats going towards them at the moment that might be Clayface's client.

"It has to be because there seems to be no connection from all the items he stole." Red Robin replied.

"Can I see the things he stole again?" Wondergirl asked. Red Robin handed a small tablet and she browsed through.

"A high carat diamond, an antique statue from Peru and a golden Chinese cup. That's odd, this cup is big and does not look like Chinese."

"What do you mean Cass?" Ravager asked as she took a look at the image of the cup.

"That is what tipped me off." Red Robin butted in. "The diamond is just an ordinary one. He could have taken the more expensive ones but seems like he took what was easy to take during that day. That statue also has no relevance to any Peruvian legends or folklore, it's just a random statue. But that Chinese cup is different, notice the symbols and design is Chinese. But the three animals that are sculpted on the handles, base and insignia on one side are a little suspicious for Chinese."

"A goat on the base, a lion insignia and dragon handles." Ravager said.

"A chimera," Beast Boy said as he took a look at the images. "You can tell by the way the dragon is designed, looks more like a snake rather than a Chinese dragon.

"Yeah, so a little piece of our history must have been wrong." Red Robin replied.

"A yacht is coming." Superboy said.

"Alright, Beast Boy and I will tail Clayface. Kid Flash you'll stay here and be on the lookout. Radio if you see anything. The rest of you hide behind those crates, when I give the signal we all jump in. Let's try to take Clayface and the items back with us." Red Robin said as he handed Kid Flash the binoculars, Beast Boy transformed into an owl and flew down and everybody else is making their way towards the warehouse.

When they reached down, Beast Boy transformed into a rat and kept Clayface in arms length which was disguising as a security guard carrying duffel bag. Red Robin carefully made his way by passing towards crates and other objects he could use as cover. After a few moments the yacht made his way beside the port. Clayface made his way towards the yacht and the door opened, revealing Count Vertigo and a few henchmen holding SMGs.

"What the hell?" Red Robin said. "This does not sound like Vertigo's MO. Maybe someone else is pulling the strings. Alright Titans, we'll have to prevent Vertigo from getting those objects. Try putting a tracer on the yacht Kid Flash so we can tail him after. If he escapes, I already placed a tracer inside the statue."

"You got it Red… wait… you placed a tracer inside?" Kid Flash asked.

"Long story, Raven you're on point."

"Alright."

"Titans GO!" Red Robin said as Raven flew towards Clayface and swiped the duffel bag from his hand. The rest of them went out of hiding and are taking down the henchmen. Wondergirl, Ravager and Superboy are putting the henchmen to sleep while Beast Boy transformed into a ram after he jumped on the yacht, helping Solstice.

"The Titans are here!" Vertigo yelled. "Stop them and secure the items!"

Kid Flash made a run from the rooftop and snatched the duffel bag in the midst of combat. As soon as he tried to run away he slipped and saw that Clayface made a carpet using his hand and held unto him.

"You are not going anywhere Speedster!" Clayface snarled as he transformed back to his original form.

Meanwhile Raven is blocking Count Vertigo's Vertigo effect. She also has a force bubble around her that protects her from bullets. As the team is fighting to take most of the henchmen down, Red Robin and Kid Flash are trying to confuse Clayface by running in circles.

"He knows I'm going to drop a cement pellet on him." Kid flash continuously said to Red Robin as he ran and threw anything he can grab on Clayface.

"French Drop then."

As Kid Flash ran towards Clayface he was on the wrist and he was held upside down.

"Too slow kid!"

"Yeah I was kinda." He replied then threw a small ball at Clayface. But that ball was swiped away and Red Robin threw a smoke bomb right under Clayface. He coughed because of the smoke and Kid Flash managed to threw the right cement pellet and Clayface immediately hardened.

At the same time, most of the henchmen were taken down but one was able to throw a grenade towards Raven and she back away because of the impact. Superboy and Wondergirl charged towards Count Vertigo but they were affected by the Vertigo Effect and fell on the ground. Solstice then shined a very bright light blinding Count Vertigo and Beast Boy transformed into a Townsend's big-eared bat and flew towards him. Because the bat can use echolocation, all it had to do was close its eyes and follow the sound. When he was near Count Vertigo enough, he quickly transformed into a Red kangaroo and gave him quick kick on the chest. Apparently the momentum as a bat and an adjusted force from the kick was enough to knock Count Vertigo from the air to nearby crates. When Solstice lowered her light everybody else was knocked out.

"I already notified GCPD. They should be here any moment." Red Robin asked as the last henchman was piled at the center of the Titans and were tied up.

"Looks like it's going to be another line of interrogation then," Superboy said. "Maybe we should do this the fast way. We could all use the sleep for the night.

"I second it. Fast option would be nice." Wondergirl agreed. Suddenly another radiant light shone not far from where they were standing.


For this mission…..different approach… limitations will affect…. gain their ways to fit in…. Adjusting… you good are…... First…. reach Hogwarts….rest shall be opened…. good luck….find the way…..

Red Robin suddenly woke up and studied his environment. He was at a small cabin, and old cabin. Seems like most of the objects around him are old or barely repaired and was looking at the roof. Then that hit him. He was on the ground so he stood up and felt a small headache and saw that Kid Flash and Raven are at either side of him wearing civvies.

"Bart, Rachel, wake up. Holy moley!" he exclaimed which suddenly woke up Bart rather fast.

"What is it? Red why are you in…. What the hell!?" Bart shouted as he pointed to Tim.

"You look young!" they both exclaimed which made Rachel wake up next.

"Who are all of you?" a voice suddenly called to their attention. They saw a man who wore worn out robes and had scars across his face and wears a light brown hair that has a few grey hairs along with it pointing a small twig at them.

"I'd gladly answer your question sir but first, where are we, and why are you pointing at us with a stick?" Bart chortled back.

"But you aren't muggles. That does not explain how you got inside my house and pass through my wards or know what I am holding. I will humor you young man, my name is Remus Lupin and you are in my cottage here and this is a wand." The man replied.

"My name is Tim Drake, this is Bart Allen and Rachel Roth. I am guessing we are somewhere in England base on your accent, what's the date and what are muggles?"

"Pleasure to meet you Tim. We are in Yorkshire of course. Today is August 9, 1993 just a litte pass seven. Well that last question probably was a joke, am I right?"

"Yorkshire, what are we doing in England? 1993, what the heck, time travel? Last thing I remember we were on a job in Gotham, it wasn't 1993. And why are we still talking to a man who is pointing a wand at us?" Bart retorted sarcastically.

"Pipe down for a while Bart. He could have done us harm if he already wanted. Does that mean you know magic sir? I also assume that you can sense magic, too. But you are mistaken my friend only I have magic." Rachel spoke up.

"Forgive me my dear, but your friends are also wizards, and what is Gotham?"

"Rachel is right sir, she is the only one who has magic and Bart is rather fast and I have no power whatsoever. Gotham is where we came from."

"Sorry young ones, but you all have magic. How about we test it? See that ladle over there? Try summoning it to you." Remus replied to them. Tim and Bart then tried to summon the ladle by a wave of hand and after a few seconds it flew towards them but they were both able to catch it.

"Alright hold up, aren't we missing something? Where are the rest of us, Cassie, Conner?" Bart suddenly shouted.

"Sorry but I did not see anyone else I don't know besides you three." Remus explained. "How about we start from what you remember."

They told him about the fragments they remember but they left out Gotham.

"Hogwarts, are you students? And why are you hiding things from me."

"Could you give us a moment for a while, Remus?" Tim requested then Remus went out of his cottage.

"I believe we all are thinking of the same thing." He said.

"Yeah, we are in a completely different world. This is not just a time travel but it kind of explains why we look younger. The question is, are we still in our multiverse? Where are the rest of the Teen Titans?" Rachel asked.

"He seems to know about Hogwarts, he could help us. What do you think Red?" Bart asked him.

"We should play this along and I think we are not in our multiverse anymore. Sounds impossible at the moment but I have a bad hunch that I am right. I don't see a good option at the moment and we can think about the others if we first can find out how we got here, besides, we are the Teen Titans. What could go wrong?"

As they called back Remus they sat around the living room while Tim remained standing.

"Alright Remus, we will tell you things. If you don't want to believe them that is not our problem but, we would appreciate if you could take us to Hogwarts in return." Tim said.

"A fair deal to me."

Tim explained to him about his world and what they were. He left a few personal things out but it was enough to convince Remus about who they are. He also learned that Hogwarts was a school for wizard and witches.

"Teen Titans, huh?" He asked. "What are metahumans and aliens are real?"

"Yes aliens are very real. Basically anyone who has ability surpassing ordinary humans can be considered a meta. In lay man's terms, a superhuman. It can be classified through various categories like magic, implants, genetics, etc. You can obtain it or either be born with it like Rachel here who has magic and Bart who can access the speed force because he is a descendant of Barry Allen, the second Flash who also created it." Tim explained.

"So you are not a metahuman? You kid are from the future? Speed force?" Remus questioned as he looked at the three of them.

"Technically, right now I am." Tim replied.

"Yes I am from the future, well our future anyway. The speed force allows me to do something like this." Bart said as he ran and paused all over the cottage which shocked Remus.

"How did you do that?"

"Well, with the speed force I am able to bend the laws of physics using super speed. All I did was to run all over the placed but I felt something was wrong." Bart replied.

"What do you mean?" Tim asked him.

"Never mind that for now. Could you take us to Hogwarts?" Bart asked Remus.

"Yes. Maybe the headmaster can help you with your situation. I have to take you via side-along apparition."

"What's that?" Tim asked.

"You could say a sort of teleportation."

"I would like to demonstrate my magic to you. However, I do not know the location of Hogwarts how about I take us back here. Would you trust us?" Rachel suggested.

"I should not but my instincts tell me I could. Very well it is located somewhere in Scotland. Now if you would please hold my hand. It will be a little bit of uncomfortable but it is one hundred percent safe." Remus said as they held his arm though Bart was rather skeptical. They disapparated after a moment and they all felt that their world was being twisted and they arrived right outside of Hogwarts. The look of awe was evident on the faces of the Teen Titans.

"Welcome to Hogwarts School of Witchcraft and Wizardry."

"Wow a school for magic. Now this is wicked!" Bart exclaimed. Then Remus took out his wand and mentioned a spell. A white light in form of a wolf appeared and ran towards the castle.

"I will inform the headmaster that he has visitors, maybe he can help you in your situation. There are protection wards so we won't be able to get in. And just so you know, muggles can't find this castle but if they did, they will only see old ruins."

After a few moments the gates of Hogwarts opened and after they all made their first step inside, the Teen Titans fell on the ground.


"Who are these kids headmaster? The boy with the red hair as a strange aura surrounding him and I can't pinpoint where it is from. The girl however, has a different aura that I have not seen my entire life."

"Calm down Poppy, they are waking up. We shall ask them questions to know the truth from all of them."

Tim was the first to wake up followed by Bart then Rachel. After a while they all stood up with eagerness in their eyes.

"So that's why. One heck of a night don't you guys think?" Bart asked them.

"Hello young ones, my name is Albus Dumbledore, headmaster of Hogwarts. May I ask who you three are?" he asked them. Tim looked at his friends and looked back to him smiling.

"Hello headmaster, we are the Teen Titans, and we came for Harry Potter."


What did they learn after they fainted? How did they know about Harry Potter?
