Lyserg Diethel(リゼルグ・ダイゼル, Rizerugu Daizeru) is a fictional character from the manga and anime series of Shaman King. He is orphaned from a young age, when Asakura Hao killed his parents for refusing to join him. This makes him seeks revenge, and eventually made him participate in the Shaman Fights to kill Hao. He would eventually join the extremist group known as the X-Laws, believing they would help him gain his revengeLyserg has a very adrogynous appearance, at first meeting being mistaken for a girl by Umemiya Ryunosuke. He has light green hair and green eyes, which he inherited from his father.
He dresses in a similar fashion as his father, and in both cases their outfits were probably a homage to Sherlock Holmes. His clothes consist of a green cloak, a white shirt with a white folded handkerchief and black pants and black leather shoes.

After Lyserg joined the X-Laws, Marco began training him and after swearing loyalty he was given a classical white uniform similar to the others.[1]. The main difference between his uniform and the others is that his skirt is completely open with nothing beneath but a pair of white short shorts and black boots, with bare legs. When not in his X-Laws uniform he wears a white dress shirt, with rolled up sleeves, a tie and suspenders, and a pair of short shorts, with his gun holster on the left side[2]
