A cartoon image of a man in a straw hat and shorts

Start with a simple outline of Luffy's body in Gear 5. Focus on his muscular physique, wide shoulders, and distinct hairstyle. Add the details of his face, including his scar under his eye, and emphasize his determined expression. Highlight the key features of Gear 5, such as the flaming aura surrounding Luffy's body. Use simple, abstract shapes to represent the flames. Pay attention to Luffy's straw hat, ensuring it's part of the composition as it's a crucial part of his character. Use a limited color palette, primarily red, black, and white to maintain a minimalist style.
