Silvers Rayleigh, also known as the "Dark King", is the former first mate of the Roger Pirates and the "Right Hand of the Pirate King". He became a coating mechanic in Sabaody Archipelago at some point after Gol D. Roger died and the crew was disbanded. He is one of the central characters of the Sabaody Archipelago arc, as the Straw Hats require his skills in order to get to Fishman Island.
Two of Rayleigh's most distinguishing traits are that he typically wears round glasses and that the facial hairs on his chin are arranged like stripes across his lower jaw. He also has a scar over his right eye, which he has had for many years. He also has many scar on his muscular body. When he was younger, Rayleigh kept his yellow brownish hair (black earlier in the anime) clean cut and had a moderate amount of facial hair. Over the years, as his hair whitened, he let it grow longer and wild. He also grew a beard from his initial striped facial hair. During his first apparison in Buggy's flashback, he was seen wearing a t-shirt with an ornately decorated collar, a motif that appeared even in the long coat he wore during the Edd War. He currently wears an orange shirt, light-brown spotted bermudas and simple sandals. He also has a silver-colored coat hanging from his shoulders.
