Rayleigh is light-hearted, casual, and fun loving, much like his captain Roger was. In the past, he was shown to have been impatient with the antics of the younger crew members and took the position of crew disciplinarian very seriously. However, he has changed his personality in his older years, becoming much more relaxed even when training Luffy.Though he often has a serious air, Rayleigh enjoys going with the flow and appearing in unexpected places and in unexpected ways. He’s even fatherly.
