Depict Monkey D. Luffy as a bold and adventurous steampunk captain

Depict Monkey D. Luffy as a bold and adventurous steampunk captain. He wears a well-worn, brass-studded brown trench coat with a high collar and a slightly tattered edge, indicative of countless battles. His signature straw hat is now reinforced with metal rims and gears, giving it a mechanical look. His left arm is a steam-powered, leather-bound prosthetic, intricately designed with visible pistons and gears that hiss steam as he moves. Luffy’s pants are made of durable, dark leather, and he wears heavy boots with metallic soles that clang as he walks.
