[Before Roger Became King of the Pirates] [Villain Protagonist] [Purely One Piece Power System] [Mythical Zoan Fallen Angel Fruit] [Building a Faction and an Army of Devil Fruit Users]
He possesses the powers of darkness and light, along with the comprehensive boosts to strength, speed, and endurance that come with a Mythical Zoan.
After awakening, he gains a monstrous ability to survive that makes him practically immortal, along with an overwhelming boost to his charisma.
That's right, this is the ultimate answer in the world of One Piece: the Human-Human Fruit, Mythical Zoan, Model: Fallen Angel.
He transmigrates to the chaotic era when Roger was still known as Gold Roger. With no System and no old man to guide him, but equipped with the ultimate Mythical Zoan and knowledge of the story's future, Lucifer thrives, rising to become the king of the world under the guise of a mafia boss!
Golden Lion: "Gyahahahaha! That brat's always hoping I'll die so he can take over my territory!"
Roger: "Lucifer is the helmsman of the Great Pirate Era!!"
Lucifer spreads his wings and declares to the whole world:
"I came! I saw! I conquered!"
Don't use your fists. It's so cool to use a double-edged sword. It's so cool to use a seven-star sword with a golden lion as a teacher. 😢
The protagonist's high-end combat power is not enough to enter the final battle.
