A/N: Hey everyone! Sorry for not updating much, I'm already got plans to update Ultimate Alien Spy and the Omniharem fictions soon so don't worry. Now I had this idea about "what if no watch Ben had a different power instead of the Omnitrix?" and then I said "What would happen if he would be a Campione instead?" and then this came out.

Chapter 1

Ben Tennyson, the God Slayer!? (Prologue)

Ben Tennyson had seen his far share of strange things recently, finding out that he had other hims in other universes, all had powerful watches that turned them into powerful alien monsters, and finding out that his Grandfather was an intergalactic police officer as well as the Plumbers (Which he wanted to to be apart of, but Max didn't want him to because of School), but this one really taken the cake. Ben was walking up to his room think of the mess he had gotten himself into, as he opened the door, his face became dark red at the site.

"Ben?" Said a female voice, the girl had long blond hair, blue eyes, and had peach colored skin, she was warring nothing at all and caused Ben to get a nose bleed at the site of her beauty. Her name was Erica Blandelli, who had just woke up from her slumber.

"Erica?! Oh crap! What are you..." Ben yelled as he covered his eyes, "S-Sorry! I didn't mean to-"

She then warped her arms around him as her large chest pressed against his back which made him more red. "I don't mind if it's you, my King." She said with a teasing way.

Ben face became even redder as she said that, Ben then got up to the.

"Got to go!" Ben said as he left and closed the door, Erica pouted and folded her arms around her large chest,

Ben panted and got some air, he still remembered how she came to his life.

He was now a Campione, in other words a God Slayer. The one who had defeated the God of Victory, Verethragne and now posed the ten Authorities: Gale, Bull, White Stallion, Camel, Boar, Youth, Raptor, Ram, Goat, and Warrior. Ben was still a little taken back at what happened that faithful day (As well as having his first kiss taken from Erica), Ben looked at his left wrist and remembered what Ben Prime told him that day when the Evil Ben's came after him.

'It's just a watch, Ben, It doesn't make you a hero.'

Ben then thought he may not be the Ben who should take up the Omnitrix, but something much more. At least it beats the mundane life of Bellwood anyway.

(Bellwood High school)

Ben Tennyson was on his ordinary schedule, as he was walking to his next class, but was interrupted when he felt his back against a locker.

"What up, Tennyson." Said the older kid, he had long black hair, dark eyes, he wore a black shirt over a long sleeved grey shirt and blue jeans. He was Kevin Levin, the School juvenile and bully. He had just started coming to this school and began to bully Ben and everyone else.

"Hey, Kevin." Ben greeted casually.

"Gimme your lunch money!" Kevin yelled with a glare.

"Sorry to tell you this, but I'm broke." Ben said with a nervous grin on his face.

"Well, looks like you are going in the locker." Kevin said as he stuffed Ben into his own locker. Kevin left laughing while Ben was inside his locker.

"Even though I'm part of the Soccer team, I still get bullied..." Ben said to himself, then someone came and opened the door of Ben's looker. It was Erica. He manged to get himself out of his locker.

"Erica? What are you doing here?" Ben asked confused by her sudden appearance.

"I thought I'll be going to your school, my King" Erica said lovingly and holding on to his arm as her breasts pressed against his arm, Ben blushed by the closeness. Ben and Erica both walked to class together while everyone watched them with jealous eyes. Ben noticed this

'Looks like I'm going to die today.' Ben thought to himself.

(In Class)

Ben was sitting in the back of his seat with a bored expression on his face, The Teacher walked into the classroom.

"Good morning, class!" She greeted happily to her students while the all the students greeted back at her.

"I would like to introduce you to a foreign exchange student to you all, she's from Italy and I would want you to treat her with respect."

Everyone nodded.

"Good, you can come in now!" She called out to the new foreign student who had walked into the class room, it was a girl with long blond hair, blue eyes, she wore a skirt and had a sweater on that showed off her well developed chest (which all the male students couldn't keep their eyes off of), she had a beautiful smile that could light up a room. Ben face palmed.

"She's hot!" A student said.

"Such beauty." Another said.

"Wow, Italian babes are freaking hot!" The third said.

"I'm so jealous!" A female student said.

"So pretty." Another female student said, the whole class was talking about her.

"Please introduce your self." The Teacher asked.

"I'm Erica Blandelli, please to meet you all!" Erica said with a smile which made all the guys go goo goo over her.

"Very good, now please take a seat where ever you want."

Erica nodded and did just that and came across Ben and hugged him. Which made everyone shocked.

"What the hell?" Another said.

"Are they dating or something?"

"How the heck can she date a guy like that?"

Every guy was now giving Ben the stink eye, Ben couldn't help but get nervous.

'Some how, I wish I had my normal life back now...' Ben said as his head fell on his desk. This was going to be a long day.

(After School)

Ben was exhausted, while Erica seemed very upbeat. Ben groaned. Ben and Erica decided to go to the Burger Shack, Ben was amazed at how much she ate.

"You sure love chili fries." Ben said impressed by how fast she ate them.

"So delicious." Erica said with a smile. "I never knew these chili fries would be so good."

"I'm with you on that one." Ben agreed as he started to eat his. "We better get going, it's getting late."

"Anything you say, my King." Erica said as she held on his arm. Ben blushed.

"You don't have to keep calling me that." Ben said. "Just call me Ben."

"Okay, Ben 10." Erica said with a grin on her face. Ben cringed at that.

"Don't call me that either!" Ben yelled blushing even redder. Erica giggled at hit reaction to his new nickname and with that they left.

A/N: Hope you enjoyed this one shot (It might become a full story if I get enough positive feed back) and I hope I got Erica's character right (I see the anime and she tends to be a huge tease), please tell me what you think and feel free to suggest which series you want Ben 10 to be crossed over with in the comments.

Good bye and see ya next chapter!
