Ace was a tall muscular young man with curly black hair. Although they were not blood related, Ace looked remarkably like his foster brother, Luffy. However, Ace was more serious looking than Luffy's lighthearted design, and was also taller and more muscular. He also sported rather childish freckles (inherited from his mother) and tended to make a skeptical facial expression by raising his left eyebrow. Interestingly, his facial features were almost akin to his biological father Gol D. Roger
