Alright, here with a new DP story, a crossover with my favorite anime/manga, One Piece! I love that manga/anime, with the action, comedy, drama, adventure and plot. Man, it's the first manga that made me cry, so emotional. So I had this idea from rewatching the Impel Down arc and remembered helping RedKnight21 with a Dragon's Frozen Will, with Danny fighting Pariah and dying, ending up reborn in the MLP world, so I'm gonna borrow the concept with Danny fighting Pariah before being sent to a different world.

So hope you guys enjoy the new story!

Prologue: Hell

Impel Down, one of the three symbols of power that the World Government represents. In this case, Impel Down represent a pirate's hell, its only purpose was to imprison and torture all the criminals around the world. A place where they only know pain, suffering, hunger and darkness, with their only escape is through death.

All the captured criminals around the world were sent to Impel Down to pay for their crimes. Once they enter, they can never escape.

But not all the prisoners were guilty.

In the first level of Hell, known as the Crimson Forest, locked in one of the many cells, sitting on the floor with chained hands and wearing black and white clothes, was a boy of sixteen with shaggy black hair and blue eyes.

"Hey, look there, seems like they caught a big shot!" one of his cellmates said, causing him to look up and saw Vice Warden Hannyabal, a weird-looking person wearing green cargo pants, boots and a Egyptian headdress, holding a spear, accompanied with a blond woman wearing the standard guard uniform. Behind them was a beaten man in chains.

He was black haired with black eyes and freckles, wearing shorts, an orange pad on his left elbow and a red bead necklace. On his back was a purple tattoo of a Jolly Roger of a smiling skull with a white mustache and on his arm was a tattoo ASCE with the S crossed out.

"Who's that?" the boy asked as he watched the man dragged away by the guards.

"Don't you know who that is?" one of his inmates asked, giving him a weird look.

"Nope."

"That's Fire Fist Ace," one of them explained. "Second Commander of the Whitebeard Pirates."

"Oh. And the Whitebeard Pirates are…"

"Jeez kid, where you born under a rock?" another one commented. "The Whitebeard Pirates are the strongest pirates out there, led by Whitebeard, the strongest son of the bitch sailing out there."

"Huh, alright," he said as he went back to looking on the ground.

"Geez, Danny, you need to get out more," one of them joked.

"Getting out would be nice," Danny commented with a sigh. "Getting home would be nicer. Then I can kill the bastard that got me in this damn place."

His eyes glowed green, causing his inmates to be silent and took a few steps away from him. He then winced, letting the glow disappear as he rubbed his chest.

His name was Danny Fenton, who was sent to Hell through unfortunate circumstances.

Unknown to him and the rest of Impel Down, his chance to get out would come soon enough, and it would change the course of the world.

Well, ending the prologue here. How Danny got in Impel Down, I'll reveal it in a later chapter, like how the background of anime heroes are revealed halfway through the story. Just seems cool to do it like that. Oh, and a quick heads up, Danny has a new power here. I mean, the title is on the nose.

Next chapter, meeting an intruder in Impel Down. Later!
