One Piece Odyssee

Adam is a towering, monstrous figure, his body covered in a grotesque network of scars that look less like injuries and more like the remnants of something unnatural. His bald head and piercing eyes exude a permanent, terrifying presence, and his shark-like grin sends shivers down the spines of even the most hardened warriors. His skin is textured, almost resembling tree bark or cracked stone. He wears a Marine-style captain’s coat, but blackened and tattered, with gold epaulets still intact—a haunting reminder that he was once part of the Marines... or at least wore their uniform. Beneath, he wears ragged, dark red pants, held together by makeshift wrappings, with black, heavy-duty boots. His right hand is shackled, a broken chain hanging from his wrist—a symbol that he was once imprisoned, though no records exist of such a man ever escaping from Impel Down. Strapped to his side is a brutal-looking hatchet, its blade chipped and darkened, as though stained with old blood

Nothing is known about his personality

Very little is known about Adam—only whispered rumors and horrific battle stories from those who have survived encounters with him. Some say he is a former Marine experiment gone wrong, a man brought back from the dead, or even a relic from a forgotten age of piracy. Others claim he was once a Vice-Admiral, betrayed by the World Government and left to rot in a hellish prison, only to break free and carve a path of destruction in his wake. What is certain is that Adam does not serve anyone. He does not conquer islands, build fleets, or hoard treasure like a traditional pirate. He simply wanders the Grand Line, appearing only when someone powerful needs to be erased from existence. His fighting style is said to be merciless and raw, relying on pure brute force and instinct rather than refined swordsmanship or flashy techniques. It is rumored that he can cut down a Sea King in a single swing and that his body is so resilient, even Haki-infused attacks barely faze him.
