When a boy in the North Blue took a stand against the world nobles, he was chosen to become the new Overlord. Now he's on a mission to conquer the North Blue and put an end to the world government. This will be heavy on OCs and will contain harem and lemons.

From boy to slave: Luffy was enslaved at a young age. From slave to killer: Luffy made his first kill, and he liked it. From killer to fugitive: Luffy's fate is sealed. From Fugitive to pirate: Luffy sails the seas after his freedom. From pirate to Overlord: Evil Always find a way. Evil Overlord Luffy, harem.

Another Luffy eats a different devil fruit but this take has Luffy becoming slightly more sinister as the story progresses.

Story 2: The Fourth Overlord is plauged by the shadow of his mighty father, and is left with no other recourse than to go beyond. A world of gold and glory is ripe for conquest, for the one that is willing to take it.

The Overlord was sent across dimensions to retrieve specimens of a fruit thing. Next thing he knew, he slammed headfirst into a pirate ship.
