Starsign: Taurus

A British Shaman and a traditional "dowser," whose parents were killed by Hao. Lyserg has dramatic interactions with all of the main characters at some point, and though he travels with them for a long time, he fights against Yoh's team more than once during the series.

Pre X-Laws: When Lyserg first encounters Yoh's group, he attacks then to determine their strength, hospitalizing both Ren and Horohoro with one attack. After Yoh knocks some sense into him, Lyserg calms down and they welcome him to come along as they search for the Patch Village. Lyserg's father, Liam Diethel, wanted him to be a detective. Lyserg's mother and father were murdered by Hao when he was six years old. Lyserg's name is pronounced differently in the English anime so that it's not a recreational drug reference (lysergic acid diethylamide). His spirit's Japanese name, Morphine, is also a drug reference (morphine). She is called "Morphea" in the English manga and "Chloe" in the English anime. He is apparently so beautiful that Ryu could mistake him for a girl.

[Spoiler: X-Laws : Once the X-Laws are introduced, Lyserg starts to question whether Yoh is truly strong enough to defeat Hao. Marco, of the X-Laws, convinces Lyserg that Yoh is too sweet and kind-hearted, but that the X-Laws have the strength that Yoh is lacking because they have the power to kill. When Yoh states firmly that he will not kill, Lyserg decides to leave and follow Marco. During the Shaman Fight, Lyserg competes as a member of X-Laws. In the anime, Lyserg discards his first spirit as he gains control of Zeruel, an Archangel provided by Jeanne. In the manga, Lyserg never abandons Morphea, even when he is presented with the Archangel Zeruel. Morphea and Zeruel combined to form Lyserg's Armour Oversoul, which in the anime was part of his final act of justice, bringing him back to Yoh's side.]

For his character, Lyserg is rather unstable when it comes to parent-child situations. He has a generally kind heart, although he becomes a bit of an anti-hero. Lyserg's dreams are to take revenge on Hao and to become a great detective much like his father. He is very passionate in his hatred for Hao, and will snap at the sight or sometimes even the mention of him. He is the most intelligent of the five warriors.
