Hellllllllllllllllllllo to my new story Ben 10 and the Wizard Conqueror! Obviously this is a Ben 10 and Harry Potter Xover. Some info that will help you before you start:

One: This is four years after Harry Potter and the Deathly Hallows, meaning there is no You-Know-Who and no Death Eaters. Also, I'm using the same teachers as in DH, minus the death eaters.

Two: Ben and Gwen have NOT met Kevin E. Levin (I'll never get over that ^-^), Michael Morningstar, Julie whatever-her-last-name-is, or anyone else from Ben 10 OR Ben 10 Alien Force. And Kevin's mom is alive (they said so in the one episode of Ben 10 AF)

Three: as I said in the summary (that sucks) Gwen and Kevin have their powers from Ben 10 Alien Force…just because I want Gwen to have some powers and I don't like Kevin's powers in Ben 10 (No offense, Kevin)

Four: Technology DOES work in Hogwarts…cause in the books it doesn't…and if it didn't then Ben couldn't have the Omnitrix and Kevin wouldn't be able to sell stolen alien tech…well he only sells a little in this story…^-^

Five: KEVIN IS NOT SOME MUTATED ALL-OF-BEN'S-ALIENS-THING AND HE WON'T BE FOR THE WHOLE STORY!!!!!!!!! (not that I would love you any different if you were some mutated all-of-ben's-aliens-thing) I don't want him to be ugly (still no offense, Kevin)

I DO NOT OWN BEN 10, BEN 10 ALIEN FORCE, OR HARRY POTTER!!!! IF YOU ACUSE ME OF THAT, I WILL SEND MY MINONS OF DEATH TO REAK HAVOK APON YOUR SOUL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

And now, without further ado, Ben 10 and the Wizard Conqueror! *Applause*

Chapter 1: Aboard the Hogwarts Express

"Wow!"

The bright red Hogwarts Express was dazzling to Ben Tennyson as he, his cousin Gwen, and his Grandpa Max walked down Platform Nine and Three Quarters. Grandpa Max and Gwen were pushing carts, Ben being too short to push his own; on each were a trunk and an owl cage. Ben ran up to the train, staring at it in awe, jumping up and down with excitement.

Ben and Gwen had received their letters from Hogwarts School of Witchcraft and Wizardry one sunny day in August, telling them to go to London to get their books and supplies for their first year at a the magical school. Gwen thought they were being pranked, but Grandpa Max had told them that his parents were wizards and he was born without magic: a squib. Ben had been excited from the very beginning; first the Omnitrix, now a wizard school! He was becoming more and more special by the minute!

Max quickly had them on a plane to London and off to buy everything they needed at Diagon Alley. Their time there was a pleasant experience…for anyone who wasn't Gwen.

Ben had begged Grandpa Max to take him to Weasleys' Wizard Wheezes, the joke shop created by the famous Weasley twins, Fred and George. (A/N: they saw an add for it in the Leaky Cauldron, where they were staying until September first.) There, Ben spent most of his money on joke products, only to use most of them up by playing prank after prank on Gwen before the first of September.

Ben started running around the platform while Grandpa Max and Gwen loaded their trunks onto the Hogwarts Express. He noticed a very thin woman with white blonde hair trying to get her son to get on the train. They boy had shoulder-length pure black hair with eyes to match. He was wearing a black shirt that looked like the sleeves had torn off, shorts that were covered in dirt and grime that went down to just below his knees, and black boots that went up to his shins.

"Mom, I'm not going! Everyone will laugh at me and call me a freak!" the boy yelled, causing some nearby heads to turn. His mother just sighed, putting on her best comforting smile (which looked pretty phony to Ben).

"Now dear, there's no need to worry. No one will laugh at you. You're not a freak, you're just special," she said, attempting to get they boy to look at her. But these words just made him angrier, opposite of the intention.

"Special is just a nice way of saying 'freak'!" he shouted, turning around and storming into the train, trying to get away from his now sobbing mother. Ben walked up to her, clearing his throat, causing her to look at him, smiling an even phonier smile than before.

"Er, ma'am…do you want me to help you get those on the train?" Ben offered, referring to the boy's trunk and owl cage that were lying on the floor. Now the woman smiled a true smile at Ben politeness.

"Why thank you very much. You're so generous," she replied, eyes shining with happiness and a touch of jealousy for whoever's son he was. She picked up the trunk and nodded towards the cage. "You can take the owl cage. Again, thank you so much."

"No problem. I help people all the time," Ben said as he brought the cage over to the Hogwarts Express. If you can count being an alien and saving people helping them, Ben thought. They placed both the trunk and the cage in before the woman turned to look at Ben again.

"What's your name, son?" she asked. Ben hesitated, but figured that she wasn't going to hurt him and was just curious.

"Ben. Ben Tennyson."

"Well, it was wonderful meeting you, Ben. Now get on the train or it'll leave without you. And that would be a loss for Hogwarts, now wouldn't it?" she said, more serious thank joking. Ben smiled and hopped on the train just as it started leaving.

Ben stuck his head out the window and waved goodbye to Grandpa Max, yelling, "Remember to write!"

"I will!" the faint reply came back. Then, all of Platform Nine and Three Quarters disappeared out of sight. Ben sighed, turning around to come face to face with Gwen. His red-head cousin grabbed his arm, pulling him down the narrow walkway. "C'mon, before all the compartments are full!"

They walked through three cars before finding one that was empty…mostly, except for one boy: the boy from the platform. Ben was about to open the door when Gwen stopped his hand. "He doesn't look friendly. Maybe we should go find another compartment," she said, urgency in her voice. Ben just shook his head.

"No. This one's fine. He's not that bad."

"You don't even know him!" Gwen hissed at her cousin. But Ben wasn't going to give up.

"I don't care." With that, Ben walked into the compartment, Gwen following at his heels. The boy looked up, but only for a second, before turning his head back towards the window, staring absently at the passing farms. Ben sat down across from him, Gwen right next to Ben. Ben, being the polite little gift from above he is (don't you just love sarcasm ^-^ ) held his hand out to the boy.

"Hi. I'm Ben. Ben Tennyson," he said in his usual cheerful voice. The boy looked up, taking Ben's hand and shaking it without even smiling.

"Kevin Levin," he said in a bored tone. He looked at Gwen, eyes lighting up slightly. "Who're you, toots?"

Gwen fumed at being called "toots," but answered anyway, in the most polite voice she could call up at the moment. "Gwen Tennyson."

"You guys related or somthin'?" Kevin asked, looking at Ben, who was grinning from ear to ear.

"We're cousins."

"Hmph. Better than siblings, I guess," Kevin said, voice still dull and bored. He finally sat up straight as a cart pulled by a plump witch came by the glass compartment door. She opened the door, looking at the eleven-year-olds' puzzled looks.

"Anything from the trolley, dears?" she asked, voice indicating that she was somewhat exhausted from pulling the cart around the train the whole day.

Kevin's face fell. He was very hungry, but had no money to pay for the candy and sweets the witch had to offer. "No."

Gwen, noticing the disappointment in Kevin's voice and the begging look on Ben's face, pulled her change purse out of her Capri pocket. She couldn't help but notice the large smile of amazement and greed that formed on Kevin's face as she opened the teal, beaded change purse, revealing its contents. "I'll have six of everything." Upon saying it, both Ben and Kevin's faces lit up with sheer boyish happiness.

In only a short hour, all of the sweets were gone, leaving the very full Ben, Gwen, and Kevin joking around with the last box of Bearty Botts Every Flavored Beans (I may have spelled that wrong), daring each other to eat disgusting looking ones. The most repulsive one was one that Gwen dared Kevin to eat: it was a chocolate brown that looked just like a bean shaped Hershey Bar; but it was actually dog poop flavored.

Then they got to the topic of what house they wanted to be in. Grandpa Max had told Ben and Gwen about it during one of their lunches in Diagon Alley. Kevin had found out from "overhearing" a fourth year taunting a couple first years on his way to the compartment.

"I'm hoping to be in Ravenclaw," Gwen said, sticking her nose up in the air with a smug, yet proud look on her face.

"Well, you are preppy enough to make it in," Kevin said, not missing the opportunity she made for him to mock her. Gwen fumed up again, and tried defending herself.

"I'm like the most laid back person I know!" Gwen declared at Kevin, glaring at him with her green eyes. (A/N- all you Total Drama Island fans out there, cheer Duncan and Courtney with me! *Woo Hoo!*) Kevin put his arms behind his head in a casual elegance only he could attain.

"Sure thing, toots. Whatever floats your boat." Kevin closed his eyes, but was still paying attention to the conversation about the houses. "What 'bout you, Ben?"

Ben's face scrunched up as he thought about it. He shrugged his shoulders, saying, "I don't really care…just anything but Slytherin."

Kevin's eyes shot open, and his eyebrows creased as he glared at Ben. "What's so wrong with Slytherin?" he asked, his voice showing his anger at Ben's statement. But Ben was oblivious to Kevin's increasing anger and continued.

"Well it's simple. Every witch or wizard who went bad was in Slytherin. Just look at You-know-who; he was related to Salazar Slytherin and was the badest of the bad. Case in point," Ben said, feeling very knowledgeable.

"You know what; not everyone in Slytherin is bad!" Kevin was now on the verge of explosion, his face getting red in rage. Ben was now getting mad too.

"Try telling that to all the Sytherin Pure Bloods! I bet you're face'll be very different after that conversation!" Ben yelled at Kevin, who stood up and headed to the door.

"Kevin! Where are you going?!" Gwen cried as Kevin pulled the compartment door open and stepped into the walkway. Kevin turned his head back to face Gwen's, black eyes full of hate.

"Anywhere away from Tennyson!" Kevin slammed the compartment door shut, shattering the glass with unknown strength. Gwen, who was closest to the door, shrieked as she jumped away from the glass shards that flew in her direction. Once all the glass was settled on the floor and benches, Gwen and Ben looked at each other, both sharing the same confused look.

"What should we do about him?" Gwen asked. Ben turned to face the window, then turned back around to his cousin.

"We can deal with him later. Right now we need to find a way to get rid of this glass before we get to Hogwarts." Gwen nodded her head in approval and pulled her oak wand out. Pointing it at the door, she whispered "Reparo" and the glass shards returned to their original place, fixing the compartment door. Ben's eyes were wide with amazement.

"Where'd you learn that?" he asked his cousin, who just shrugged in return, replying,

"I skimmed through a couple of our books and found this spell. It seemed useful, so I made sure to remember it."

Gwen moved to where Kevin was sitting and looked out the window; Ben followed suit. They could see the castle from a distance. Realizing how close they were, the cousins pulled their black robes over what they were wearing. (A/N- I'm going with the book here: they don't have uniforms, they just have to wear the robes over their usual garb)

In no time, they reached the platform and the Hogwarts Express's doors opened, spewing out the students. Ben and Gwen were among the last to exit the train, but soon found out where to go, due to the booming voice yelling, "Firs' years! Firs' years ov'r here!"

They headed towards the voice, which was coming from a very tall man with tangled dark brown hair and a beard. Ben nudged Gwen's side. "Doesn't that guy look like a giant!" he whispered with enthusiasm. Gwen, however, made a disgusted face at Ben.

"Don't say that! It's rude," she whispered back.

They followed the crowd of first years to a huge lake that gave a perfect view of the castle. The torches' light reflected off the black lake, giving the castle an even more magical look that it already had.

They all got into boats, the giant's at the front, with all the other's behind, spreading out father as it go to the back, making the boats a pyramid floating across the water. In Gwen and Ben's boat were a girl with short, straight black hair and a boy with blonde hair, who—to Gwen—wasn't bad looking at all. He caught her staring, causing her to turn back to face the castle, blushing madly.

When they got to the castle, they were lead inside and up a staircase, only to come face to face with a some-what tall man with dirty blonde hair that was cut so it was just past his earlobes. He was wearing a long navy blue robe with a light blue shirt and black pants under it. Around his neck was a black and green amulet connected to a chain. He smiled as the first years came face to face with him.

"Welcome to Hogwarts," he stated in a husky, yet cheerful voice. "In a few moments, you will walk through these doors and join your classmates. But before that, you will be sorted into your houses. Here at Hogwarts, your house is like your family. Each house can receive points that will be added up throughout the year. Your triumphs will earn you points, while any rule breaking will loose you points. At the end of the year, the house with the most points will be awarded the house cup."

Ben heard a snort behind him, and turned to see Kevin, standing alone at the edge of the group, with a bored smirk on his face. Ben turned back around to face the man in the blue robe.

"The sorting process will begin momentarily," he said before turning to enter the oak double doors behind him. Once he left, the group did as any other large group of kids would: start talking.

But they all returned to silence as the doors opened to reveal the man. "Follow me."

They walked into the largest room Ben had ever seen. It had four long tables in columns, each one filled from the back to the room to the front, only leaving about a tenth of the table open for the new first years at each table.

Ben looked up and swore he could see the sky…but that was impossible. They were inside.

"It's not the real ceiling. It's bewitched to look like the night sky," the black haired girl from their boat informed him. Ben smiled at how knowledgeable she was. "I read about it in Hogwarts: A History."

"Cool," Ben replied with a huge grin on his face. Suddenly, the group stopped walking, and Ben—with his attention span of a squirrel—didn't notice and ran into Gwen.

"Ouch! Watch where you going, Ben!" she angrily whispered to him. Ben just shrugged and looked up to the man in the navy blue robe, who was now holding a very old brown hat in his hand. There was a wooden stool next to him that looked very old and not really stable. He pulled out a list and cleared his throat.

(A/N- sorry that there's no Sorting Hat song…I'm just way to lazy to write one)

"When I call your name, come up and I will place the sorting hat on your head, and you will be sorted into you houses," he said, glancing at the hat. "Natalie Anderson!"

A tall brunette walked up, nervous written all over her face. She sat down on the stool and the hat was placed on her head. It started to move and then suddenly yelled into the hall, so loud even the students in the very back could hear.

"GRYFFINDOR!"

They table farthest to the right of Ben busted into applause. Natalie jumped off the stool happily as she skipped over to the Gryffindor table, receiving many hand shakes and high fives from the students seated closest to her.

Many names were called until one name came up that made both Ben and Gwen stiffen.

"Kevin Levin!"

Kevin POV

I was suddenly brought out of my daze as I heard my name called. Not wanting to ruin the image I've set for myself in these short minutes since entering the school, I walked up to the stool slowly and casually, slouching as I sat down, an "I-don't-care" look on my face.

The hat was placed on my head and the creepiest thing happened. I heard its voice in my head!

"Hmm…very interesting. A clever mind, but very devious. Ruthless and barbaric, doesn't really think before acting." Now this made Kevin uneasy; the hat was reading him like an open book!

"Terribly hurt and secretive. But what's this! What a strange ability. Hmm…yes…he'll belong perfectly."

"SLYTHERIN!" the hat screamed. Now the table farthest to my right (Ben's left) was applauding. The hat came off of my head and I walked over to the table, not missing Tennyson's look of disgust. I smirked as I sat down, receiving many pats on the back.

I fell back into my daze as some Slytherin older student tried telling me all about their amazing and ancient traditions and more first years were sorted. Then, again, I was pulled out of my daze upon hearing the name of my mortal enemy.

"Benjamin Tennyson!" I smirked. His name's Benjamin!

Tennyson walked up to the stool and the old as hell hat was placed on his head. It only took a second before the hat came to a decision.

"GRYFFINDOR!" Again, more applause. I hope I never hear another applause after today!

"Oh! And Gryffindor is our enemy house," the moron next to me said. Finally he had my interest.

"Why?" I asked, actually curious.

"Well, it goes back to the founders of our school. You see…" Ok, not interesting anymore. I looked back up to the school to see Tennyson's cousin—what's her name again? Glen or something—on the stool with the hat on her head.

"RAVENCLAW!" the hat yelled. I smiled, but then quickly turned it into a smirk. Kevin Levin does not smile. But I was happy…for her. She had gotten into the house she wanted. She must be smart.

But that doesn't make sense! All smart girls are supposed to be ugly geeks. And she was so beautiful…

Shut up, Kevin! Do you hear yourself! You're going soft!

I sighed and turned back to the table as the last person was sorted. Then, some really wrinkly old lady stood up, raising her hands, saying, "I won't keep you waiting any longer. Let the feast begin."

Food by the thousands appeared before my very eyes. I had never seen so much food in my life! I looked greedily at everything, filling my plate with as much as it could hold. I soon forgot about Glen and her moron cousin, Tennyson, only focusing on the food in front of me.

There you go…so how was it? I would love it if you'd review…pretty please?
