A/N: A new story! I came up with this story the other day and it wouldn't leave my head, I just had to write it! As I said in my now canceled show (I will release an expiation video sometime in the future explaining why I stopped making it) I mentioned that there needed to be more crossovers between One Piece and Star Vs. so yeah... I came up with a good story. Anyways I hope you all enjoy it!

Disclaimer: I don't own Star Vs. the Forces of Evil or One Piece, if I did then that would probably mean I own Disney... and if I owned Disney I would own the World!

Star: What?

Emma: reference to the Fox Deal that went official a few days ago...

Monkey and Butterfly

Prologue

The young 6-year-old Princess of Mewni Star Butterfly smiled and giggled. She had found where the servants of the castle kept their dimensional scissors. She had managed to steal one of them.

"Let's do this!" she cheered.

She cut open a hole in the air, creating a bright ocean blue portal. She jumped right into it cheering.

She found herself in a forest and she ooed and ahed at everything.

Then she heard a yell. She found it was a boy the same age as her.

"Why does Grandpa keep doing it!" yelled the boy.

"Hi there!" cheered Star.

The little boy turned around, he was surprised as a such a well-dressed girl the same age as him.

"Who are you?" asked Luffy, "And why are you dressed like a Princess?"

"I am a Princess! My name is Star and I'm from another Dimension!" cheered the young Princess.

"Oh I'm Luffy!" cheered the boy.

"What are you doing in the forest?" asked Star.

"My Grandpa left me here to train!" said Luffy.

"Oh that's too bad! You want to go exploring with me?" asked Star.

"Sure!" cheered Luffy.

And so began the friendship between the two… and it would grew into some far more powerful… they would eventually see each other as family.

Next Time: Star is forced to go to Earth to train to be a Princes, however she ends up alienating her new roommate. But when an enemy shows up, she must team up with her roommate and brothers to fight him off! What will happen? Find out next time!
