In a world of Devil Fruits and Haki, a new power has awakened. When the might of Marvel's greatest heroes is placed in the hands of a child bent on revenge, the Grand Line will never be the same. Riven, a young survivor with a two-billion Berry bounty, has declared war on the World Government. Backed by an army of resurrected legends and armed with powers the world has never seen, he will carve a path of destruction straight to the One Piece. But will this new power save the world, or shatter it?

[One Piece, F!Reader] Being one third of one of the legendary ancient weapons sounds like a dream come true. 'Unlimited' power? The ability to see the future? Think more like having a nagging sibling/weapon in your head, a freaky blood colour and killer headaches. Not to mention being a notorious (ex)assassin. It's just like the world's happy to see you shoved under the rug as a freak of nature. So when the Straw-hat crew shows up in Loguetown, you jump at the chance to prove yourself. Time for the world to see you are more than the sum of your parts! Current arc: Thriller Bark

If you're new here... I really hate writing descriptions.... if you're not new here.... I started re-watching One Piece again....expect more stories >.< hahaha

First year in the Marines "Loyalty, Justice, Courage!" Fifth year in the Marines "If you don't take it, and I don't take it, then how could Admiral Sengoku ever take it? And if Admiral Sengoku doesn't, how are we supposed to move forward?" Tenth year in the Marines "Fleet Admiral Sengoku, why won't you stand up and clash head-on with the Five Elders in Mary Geoise?" That year, Ortoren enlisted as a fresh recruit, his head full of ambition-dreaming of rising through the ranks and seeing the world for himself. Years later, Ortoren became commander of G-5, leading nearly eighty thousand elite frontline Marines. By then, loyalty was all he had left to cling to. Later still, he rose to Admiral of Marine Headquarters, entrusted with overseeing the New World. With hundreds of thousands under his command, his power rested on one simple truth: "The Five Elders praise my loyalty and courage, and Fleet Admiral Sengoku treats me as if I were his own son." In time, Ortoren commanded armies numbering in the millions. At his word, the seas themselves seemed to tremble. One day, as he walked through Marine Headquarters, a group of officers suddenly surrounded him. They overpowered him-the strongest man on the seas-and draped a yellow robe across his shoulders. "It's cold, Admiral," they said. "You should wear something warmer." Looking into the earnest eyes of those officers, Ortoren let out a long, weary sigh. "After all these years of loyalty, my name is ruined in an instant. You've truly done me in."

Chosen to transmigrate as Luffy (OC) for the first episode of the work with wishes OP. I always wondered how Luffy's adventure would be with the most powerful and serious character, so I created this story. The story may start off nonsensical, but I wanted to incorporate these aspects from the beginning: Luffy Fruit: Moa Moa no mi, and Eikon Eikon No mi: Chaos Ifrit! Powerful body with your zoan from the start. Yamato, Shirahoshi, Kuina, and Trafalgar Lami from the beginning with Luffy! There will be a harem. This is an Alternate Universe (AU) with OC, so there will be some changes, such as OC -> Luffy, Law -> Lami, and Luffy (Original MC) -> Lucy. (#Genderbend) Got it! If there are elements of Final Fantasy 16 and the addition of Eikon as mythical Zoans, I'll keep that in mind, including the possibility of colossal battles. --- ------------------------------ With gratitude and enthusiasm: Raccoon Welcome to the Raccoon Explorer's League! ------------------------------ Explore the Unexplored!

Over 100 years had passed since the battle against Muzan Kibutsuji. All the participants that fought in that gruesome war had all passed away during a time of peace from a world without demons. Yet, one from that time is still around. Yushiro, a demon boy created by Lady Tamayo, is at his home painting portraits of her so that he can remember her forever. He wanted to end it all, but Tanjiro told him that he should live on to keep her memory alive. In all of these years, new world powers took over. Marines and Pirates. Marines were supposed to be the good guys and Pirates the bad ones. Yushiro, of course, didn't want anything to do with either of them, but can he really keep his life peaceful even in this Pirate Era?

This story is basically a reader insert. Meeting a lot of characters from the series One Piece, and having her story told. I do not own One Piece and the picture at all. The credit is given to the creator of One Piece and the artist of the photo. I do own the story that I have written.

If someone hurts Luffy... that person's gonna have a bad time.

After traveling through time, I awakened as Luffy-now bonded to an invincible system. Destiny calls me to rise and claim the title of Pirate King. Naturally, catching Nami's attention is one of the many "benefits" of walking this path.
