Author's note:

Hi! so If you are a Tumblr person, then you might know what this is about. There's this Bad Boy Marco AU, where Marco is actually a bad boy (duh) nad Star is...well, a proper, refined princess. The credit to this whole AU goes to fullysketch. I hope he likes it!

Star Comes to Earth

-Part One

Let's start with the intro...in case you don't know, there's another dimension called Mewni. There is a queen, a king, and Princess Star.

There used to be times where Star was an outgoing, creative, and quite wild, girl. She wasn't anymore though, thanks to getting an appropriate education at St. Olga's all traces of her individuality were gone...or at least hidden.

"Star, dear!" The princess rapidly headed downstairs, her small hands picking the ends of her blue dress as she went down each step. She followed her mother's voice, which lead her to the main hall.

"Yes Mother?" She asked politely, her hands tucked behind her back. Her hair was in two long braids, which ended with big red ribbons.

"Star, your father and I have been discussing, and we think you are ready to prove yourself with the wand," the queen stated, glancing towards the King. Star nodded, bringing her wand out of the small purse she was carrying.

"Oh, why thank you and-"

"We weren't done Star." Star widen her eyes and looked down,

"I apologize." The king shook his head while his wife sighed.

"As I was saying, you are going to show us if you are ready for the throne. So we've decided to send you to this other dimension called Earth." Star gasped silently.

"Earth?" She repeated, the name sounding so odd on her lips. The king nodded and marched towards her,

"Why yes! It's the perfect dimension, and they have no magic there!" He said, trying to cheer the princess up as he saw her bewildered face.

"We already made arrangements on where you are staying, Star." The queen said tiredly.

"so pack your things, we'll meet you outside. The guards are ready." Star nodded.

"yes Mother." And just like that, Star bowed and walked out of the hall and into her room, already thinking about the marvelous things waiting for her. Oh yes, she has read so many books about Earth...she just never really found it attractive. But this was her chance to expand her knowledge. And she would be staying at someone else's house, is not like she would be abandoning her high-class castle. And her mother probably set her with a group of highly polite and refined people. Yes...it wouldn't be so bad.

Marco groaned as the clocked continued ticking. He looked around, finding Janna with a pencil on her mouth. He smiled to himself before tipping over his chair and hitting it, making the pencil fall on the floor. Janna frowned, but once she saw Marco, she shook her head with a sly smile.

Marco smiled to himself, tucking his hands into the leather jacket he was wearing. He was always wearing a red hoodie below it, along with a red beanie and his normal jeans. He took out some bubblegum and his fingers quickly got rid of the wrapper before putting it into his mouth. He began to blow on it, making the teacher glare at him.

But that was Marco. The bad boy of the school.

"Marco Diaz, please report to the principal's office," the speaker echoed. Marco chuckled, feeling everyone's gaze on him. He smiled.

"Let's see what I did this time," he thought out loud.

"Go Marco!" Janna yelled from the back. Marco saluted his best friend before heading out. He sighed once he got outside. He fixed his jacket and bended down, an untied shoestring was bugging him. What if he tripped?! Untied shoestrings are a major hazard in his opinion.

As he finished tying it he headed towards the office. He could hear some people talking inside it.

"This is... From Mweni...yes another dimension...won't cause trouble...we'll pay money..."

Marco rolled his eyes, he always did when people tried to solve things money. Not everything can be solved with it. Geez.

The door opened and two grown ups stepped out. One of them was quite short and had a large beard, he nodded towards Marco. The other one was a female, she was tall and had a fancy crown. She glared down at him then shook her head.

He groaned and then without looking he stepped into the office, bumping into someone.

"Hey! Watch where you are going!" he fixed himself before looking up. There was a girl with the same kind of dress that the other lady was wearing. She had two long braids and her skin was as pale as the snow. He smiled cockily.

"I'm sorry, it was my bad," he stuttered, rubbing the back of his neck and smiling at her. The princess rolled her eyes and crossed her arms over her chest.

"You should. I'm royalty and I could easily have you in prison by now if I wanted to," she responded. Marco chuckled.

"Name's Marco. Marco Diaz. What's yours princess?" he said sarcastically, extending a hand towards her. The princess glanced between him and his hand, in the end she decided against it.

"Princess Star." Marco nodded. He was about to add on when the principal finished whatever he was doing behind his desk and asked for their attention.

"Marco, as you can see, this is Star. She is the princess of Mewni," he started. They both looked at each other and then looked away...annoyed.

"And Star, this is Marco, your guide."

"WHAT!?" they both yelled.

"Sir, I can't be with him! Just...just look at him!" Star said, panicking. Marco rolled his eyes and leaned at the nearest wall.

"Well don't feel special princess because the feelings are mutual." Star gasped.

"Did you hear that!? That is just plain rude!"

"Seriously princesa, chill." Marco sighed, it was unbelievable how she was getting on his nerves. And Star thought the same. Marco was exactly the type of people she didn't want in her life. Marco was a rude, careless, and...bad. Yes. That's what he was. The boy with the bad reputation.

"I'm sorry but I don't take advice from people with records." Marco groaned.

"I hate you so much right now," he whispered, narrowing his eyes at her. Both of them turned to see the principal, who was shaking his head.

"Marco, you could use some good influence on your life, and Star, blieve it or not, Marco is one of the top students here." Star gasped and looked at the boy, who just shrugged.

"Looks like the joke's on you, princess," Star narrowed her eyes, in her mind going over a million spell that could destroy the guy in front of him.

"So that's the cafeteria. Those are lockers. There's some classrooms. That's a water fountain," Marco listed in monotone. Star was following close behind him, and as much as she didn't show it, she was curious for each place.

"And we are done here. Nice to meet you princess but this guy has to go," Marco mockingly bowed at her, and then swifty he turned around and began to walk away

"Hold on!" but before Star could ask him more about it -the school, her schedule, and the people- the boy was long gone.

"Ughh humans." She took out her wand and a piece of paper that her mother had given her.

'Mr and Mrs. Diaz household.' Star narrowed her eyes when she read the last names.

"I guess everyone has the same last name." she said to herself, and moment after with the help of her wand, the girl started to walk towards the house she would be staying in.
