I do not own Harry Potter, or Doctor Who, or DC Comics, nor any other references I may use at any given time.

I saw a rather cool crossover of Harry Potter, Doctor Who, and Percy Jackson a few days ago, and I was struck with inspiration. I really like the Doctor Who series and was probably going to do a fic with it, but this one is what I have come up with. I have also been looking for an original 'in' into the DC or Marvel universe, and I thought that Harry becoming a Gallifreyan would be an excellent, if roundabout way to do it.

Well, I hope you guys enjoy reading the exploits of the Time Lord from Little Whinging, arriving in the big Jump City.

Starting Chapter

"I love Pizza!" A young green-eyed male yelled out as he took another bit out of the ketchup, pineapple, and guacamole pizza, a myriad of colors streaked across the thick crust pizza.

"I mean, it's not as good as fishsticks and custard, but I like it." The young man muttered, taking another bite from the cheesy goodness.

Potter, the young time lord of the DCAU Universe, was currently attempting to create a way to meet up with his oldest friend, Raven, after not seeing her for almost 7 years. At least, he wanted to not have to regenerate right after saying hi.

So he decided to grab a bite to eat, and was extremely surprised to see her with the Teen Titans, also grabbing a few slices of pizza.

"Titans Go!" the streetlight dressed character, Robin yelled, as the superhero group started to save a baby carriage from an oncoming bus. Starfire, the Tamaranian Princess, flew the carriage out of the way, while Cyborg, Miss Martian, and Raven worked together to stop the bus.

As Potter watched the baby turn out to be a teddy bear, and the Titans get attacked by the H.I.V.E. Five, he decided to step into action.

He still wasn't supposed to, mostly because his 15th birthday was a week away and he promised his mother not to start until he was fifteen, but Potter thought that she could let this go.

Jumping down off the Pizza Corner building, Potter pulled out his mask, a simple piece of dark purple cloth, with two eyeholes, completing his costume. With black military boots, black loose cargo pants, a black shirt with the Gallifreyan word for Potter on it, and a grey scally cap on his head. That with the 10th Doctor's overcoat, and he looked quite outrageous by most terms. Especially since there was no hint of spandex on his person.

Completely psychotic for a superhero.

Before he touched down, Potter clicked his boots together, which triggered a release mechanism for his hover-skateboard.

Floating for a second as he watched the water from Aqualad's swords be turned into jelly, by the sister of Mammoth, Shimmer, Harry decided to make his appearance.

Potter was very surprised by the line-up of heroes and villains. There was Robin, Kid Flash, Aqualad, Starfire, Miss Martian, Raven, Cyborg, and Beast Boy from the Titans. And on the H.I.V.E. Five, there was Mammoth, his sister Shimmer, Jynx, Gizmo, and Billy Numerous.

"Hello, how are you all doing on this fine day?" He asked, floating from behind the genius of the group, Gizmo.

"Narfbag!" The diminutive genius yelled in surprise.

"Why thank you, and greeting to you too," Potter said, "My name is The Potter, and I will be your hero today."

Slipping his hand into his pocket, Potter brought out his own sonic screwdriver, capped with a yellow light, before pointing it at the midget's backpack.

The bright yellow glow and shrill whirring sound, marked its use and the earth tech went out of control, sending the screaming boy flying through the skies like a certain trio of Poke-thieves.

Laughing at the sight, the young time lord's arrival threw both teams off their game. Apparently, seeing the British-sounding hero was something neither team expected.

The villains were the first to get their heads back on, though Billy seemed to be having some trouble, so many heads and all that.

Kicking the mechanical man in the chest, Mammoth raced towards the Gallifreyan, intent on taking revenge for his friend. However, he was stopped by the green shape-shifter, who took the form of a gorilla in order to match the larger teen's strength.

Shimmer however, was able to slip by the leader of the Titans, having turned his Bo Staff into cardboard and kicking him in the chest.

Raising himself slightly out of reach, Potter then thought about his next move.

He could go for the transmuter, using his board and limited martial arts to knock her head with the hoverboard. However, if she was able to change his clothes to lead or his board to wood, then he would be out of the fight for a bit of time and probably taken out easily. Potter could help Beast Boy against Mammoth, but seeing as both Kid Flash and Aqualad had already moved into position to help him, it would be rather over the top. He couldn't go for Jynx, because his main weapons, his tech, would be completely destroyed by the unlucky bolts, or Hex Bolts, of the pink-haired villain. So, Potter went after Billy Numerous, going to help Miss Martian and Raven.

This whole train of thought only took a second for his Gallifreyan mind.

"Do you lovely ladies need any help?" Potter asked, hovering over the heroes, who were crushing groups of Billys after Billys.

Potter reached into his pocket, pulling out a small metal ball before tossing it into the largest crowd of Billys.

A large flash was the only warning before a wave of sonic energy knocked all the Billys down, till only one was shown to be left. The original.

"Well, I think you guys can handle this guy now." Potter said, nodding towards the single clone-man, still dazed from the blast.

Looking around, Potter saw that for the most part, it was only because of overwhelming numbers that the Titans had won the day.

It was obvious that Kid Flash and Aqualad were excellent teammates and worked very well together, but they were the only ones whose teamwork was good in the fights. Robin wasn't used to working with Starfire or Cyborg, and Beast Boy was left behind by the two Young Justice founders. Miss Martian and Raven couldn't work together, what with Raven's protective shields around her mind preventing telepathy.

Soon, the H.I.V.E. Five were round up by the police, Gizmo's angry profanity sounding faintly from within the police truck.

Watching as the criminals started on the road to, hopefully long and redeeming, prison terms, or more likely, juvie, Potter felt the eyes of his new friends on him.

"Now that that is over, who are you?" Robin demanded, crossing his arms over his chest in annoyance. He really didn't like that he needed help.

Looking around, The Potter saw that only Starfire and perhaps Miss Martian were on his side.

"Perhaps we should bring this to a more secure location? Shall we?" Potter said, waving his hand towards Titans Tower. The others besides Robin, who didn't seemed to be giving him the benefit of the doubt, quickly assented to the reasonable request. No one wanted more drama than there already was, especially in public.

Almost too soon after, the group was comfortable in the architecturally impossible building, and Potter was surrounded by the second most powerful super-teen group in the world.

"Well…" Robin stated.

"Umm, Hi. My name is The Potter, and I would like to ask to join the Titans." The time lord said, watching as Raven's eyes widened at his name. a small potted plant was covered in black energy and exploded.

Faster than the adult Flash, Potter was slapped and then hugged by his childhood friend.

"Where have you been!?" Raven yelled, shaking Potter by his shoulders. Then, all at once, she turned her head and turned crimson.

The other Titans were shocked. They may have not known the half-demon long, but to their entire knowledge, she was the very definition of loner. Seeing her hug anyone willingly, much less show so much emotion was a sign of the apocalypse.

"Robin, I can vouch for my friend here, he is a friend from my childhood. Though, he is going to have to explain where he has been these last few years…" Raven said, giving the British sounding alien her patented Raven-Glare.

"Umm, well, I've been around. I spent a great amount of time in Kansas, surprisingly. Met a young man, pretty interesting guy. I also have had some fun on one of Jupiter's moons, but that's for another time." The Potter said, almost losing control when he saw the faces of the Titans.

"Wh-what? I don't understand, Friend Robin, is this one of those jokes of the bad like the ones Friends Beast Boy and Kid Flash do?" The Naïve Tamaranian teen said, a question mark appearing above her head. The two 'jokers' hung their heads in shame, having been insulted unknowingly by the cute girl.

"Unfortunately not, my friend here is an alien like you and M'gann. He just likes to confuse people." Raven answered, though even she was surprised. Though that was mostly about the Kansas part, since there was almost nothing of interest there.

"Really, you are an alien? Oh this is most wonderful! It is a pleasure to meet you, friend of Friend Raven!" Starfire yelled, taking the time lord into a sweeping hug. Robin growled quietly in the background, a small tick on his brow.

Miss Martian, the more sensible of the two sensual alien females, also seemed quite happy, though she also held a look of confusion.

"Hey, what species are you, if you don't mind me asking? What planet are you from?" She asked, her clothes melting into plain black and red sweatpants and a t-shirt. Who says superheroes can't get comfortable.

"Well, I'm a Gallifreyan. And my species come from the planet Gallifrey, even if I was not born there." Blank looks seemed to make the alien boy sheepish before he decided to continue.

"Well, Gallifreyans are rather advanced lifeforms, because of the anomalies from around our home. I may look pretty human, or rather, humans look Gallifreyan, but one of the largest differences in our two species is that we have two hearts." Potter said, gaining looks of surprise from his audience.

"Wait, dude, you have a back-up heart?" Beast Boy exclaimed, jumping up and yelling how cool that must be. Potter laughed at that, though he truthfully didn't want to delve much deeper into his ancestry or powers. Some would seem more frightening than others.

"Ah no, they work in tandem. If you used a heart monitor, I would have a four beat rhythm instead of just two beats." Potter said, chuckling at the expression on the shape-shifters face. He probably knew the most about anatomy, considering his powers.

"Are there any other abilities that are unique to your race?" Robin said, uncrossing his arms as he calmed down.

"Mostly just an increased brain capacity, our dual hearts were built to support the amount of blood needed to fuel our minds. As a whole, Gallifreyans have an eleventh level intellect, with some of our best and brightest going above and beyond twelfth." The teenaged time lord said, shocking those present.

That was probably the most shocking, since on a whole, intelligent aliens were much more likely to be evil than simply super strong ones.

"Why have we not heard from your people, if they are so intelligent, Friend Potter?" Starfire asked.

"Well, partially because we are an observant race. We would rather watch how time flows and bends through history than interact with it. It might also be because I am the last Gallifreyan." The Potter said, a morose but controlled smile on his face.

Miss Martian could understand the feeling, since it was only her and her uncle, The Martian Manhunter, left. However, Kid Flash, whom had left after learning he was a friend of Raven's, rejoined and completely destroyed the somber mood.

"Hey, what kind of superhero name is Potter, anyway? Is it even a super name?" This earned him a punch on the arm from both Cyborg and Aqualad, even if the new alien was happy for the change in topic. It may not affect him as much as it did The Doctor, never having been to the planet, but he was pretty much alone.

"Well, our titles are chosen when we reach a certain age. We stare into a vortex of time energy, watching as our own personal history flows right by us. We can't really see much, just flashes, but we can hear those who call out to us, and the name they call is our title." The Potter said, watching as the looks of understanding came on the faces of his hopefully new friends and comrades.

"Our titles are usually professions or items that describe us and our actions that will happen in the future. I knew a few other Gallifreyans, but there was this one, called The Master, who only sought to conquer the galaxy. He was stopped thankfully." Potter continued.

"So, as a potter, you would be making awesome pots?" Beast Boy questioned, kind of bummed out by the strangeness of it. However, it caused The Potter to laugh.

"No, it means that I will probably create something lasting in the future. Potter, Doctor, Master, Architect, these titles mean more than just a profession. They mean we will be the creators of the word. We are the word, its true meaning." The Potter stated, then slumped down into his seat.

"Hey, you guys mind if we continue this tomorrow, I want to get my ride and go to sleep." He stated, looking out the window to the sun, half of it disappeared behind the wall of ocean.

"Umm, sure man, why don't I set up a room for you…" Cyborg said, before Potter shook his head.

"Naw, it's ok. I got a nice place to stay at least for the night. After that we can figure something out." With that, The Potter reached into his pocket and pulled out a small metal key. One you would use to open a house.

As the young time lord walked over to an open part of the room, he and Raven simultaneously smirked at the small joke. Potter acted as if he were to push the key into a lock in midair, leaving the key there as it floated.

Before the teens' very eyes an old-fashioned police box, one used in the city of London, appeared before the group. It was old, not by look, but by feel, and it could only be described as blue. Blue and old and new.

"Cheers then and all that." The Gallifreyan said, before closing the TARDIS door.

Robin felt, for all of three seconds, that he must get to the bottom of this, before watching as everyone excused themselves, leaving mechanically to escape the craziness of the rather bulky machine entering their home.

The next morning, the fabulous blue box still rested in the corner, providing a rather insightful view into the colorful language of Robin and even Cyborg. Poor innocent Starfire learned quite a bit that morning, and it would be quite a while before the rest could explain that those were not words a princess should be repeating. Before long however, it became a normal Tuesday morning for the group of superteens, fighting over meal choices and celebrating the fact that none of them were going to have a rounded education.

So when a wet Potter came out, with a towel and bathing suit on, the normality level was destroyed.

"Well, hello, and please don't gander. I just got out of the pool." He said, before plopping right down next to the large robotic teen.

"Wait a moment, where is this pool?" Cyborg asked, dismissing the idea of a pool being anywhere close, despite the fact that Potter definitely smelled of chlorine.

"Well, it's in the TARDIS." Potter said simply, grabbing the hash browns and ketchup.

"TARDIS?" The Teen Titans all asked.

"Time And Relative Dimensions In Space. My beautiful blue box over there is a time machine." The Gallifreyan replied.

At that the room erupted into noise, and Miss Martian even went to poke her head into the open door, before squeaking.

"It-It's bigger on the inside!" She yelled, and a wave of satisfaction and nostalgia came over Potter, from both the videos of The Doctor, and the time he showed Raven around. She really liked the library.

"Oh yeah, the TARDIS isn't actually here, in this dimension. This is only a portal to a completely separate dimension that houses the actual ship." He said, as if only just remembering.

Potter was actually a bit sad, if only because the reactions after that were minimal. Being heroes meant weird stuff happened on a weekly basis, and he would never be able to show off unless he started to take civilians on rides.

After finishing up breakfast, The Potter began a little tour of the time machine. It was Cyborg and surprisingly Kid Flash who were the most excited, both being much more into science than the occult stuff usually surrounding the wonders of dimensional travel.

The control room was very different than the old ones, which usually were formed in order to give a rather strange combination of alien and earthlike tech combined. Overall, the dark grey room was almost like a miniature batcave, built for both controlling travel and hero work.

The pool was huge, the largest room in the ship, well besides the engine room, but that was beside the point. Next up after that was the library, where the group left Raven to catch up on some of the more ancient texts that she could find.

Going through the map room, three of the master bedrooms and a fully automatic kitchen, the group finally arrived in the athletic room. Complete with a track, sets of weights and a sparring pad, it made Robin salivate.

Walking back to the library to pick up Raven from the library, he was met halfway by the angry sorceress.

"Who's that!?" She said, pointing to a young girl kissing a young Potter on the cheek, blushes staining both their cheeks.

"Oh bugger me…" Potter said.

Ending Chapter

MuaHAHAHAHAHA

Now I leave you a cliff-hanger. I know this chapter had a lot of information and changes to canon, and if some of you didn't really like it, well you probably didn't make it this far so those guys are suckers!

You know what I hate, when you are trying to type to and it ends up to be ot. Does that happen to anyone else? I swear it makes me mental.

This chapter may not be as long as I would have liked it, but I so badly wanted to know what it felt like to leave you guys with this cliffhanger.

Well, since I have no other things I want to say…

No Flames Please

Review If Possible

P.S.

If anyone wants a group of titans to go on a vacation anywhere exotic, review it. Remember, with time travel, vacations are never an issue for the heroes.
