One Piece: I Ate the Adaptation Fruit!

In the treacherous and chaotic era of the Grand Line, where Devil Fruits and Haki dictate the rules of survival, the protagonist unexpectedly transmigrates and consumes the ultimate Paramecia: the Adapt-Adapt Fruit! His core directive is ruthlessly simple: passively adapt to any attack, environment, or negative state to negate damage, and evolve infinitely in the crucible of battle! Armed with this reality-bending evolutionary physiology, his journey completely shatters the traditional logic of the One Piece universe. While legendary pirates and Marines struggle to master their abilities, the protagonist is casually redefining the meaning of true supremacy. Whether it's developing immunity to lightning, hardening his skin against extreme heat, or using his awakened domain to weaken enemies' perceptions, his unapologetic rise redefines the meaning of true supremacy. From a rookie adapting to the harsh New World to the undisputed apex existence who single-handedly alters the outcome of the Paramount War and challenges the Four Emperors, he turns the entire ocean into his personal stage of divine evolution. This is the ultimate unapologetic anime power fantasy about achieving absolute supremacy through extreme "adaptation mechanics" and supreme "ocean domination." If you love mind-blowing power scaling, watching arrogant villains and legendary figures get completely outclassed by a max-level protagonist's god-tier passive evolution, and experiencing the most satisfying and unconventional One Piece conquest ever, this is the definitive anime masterpiece!
