Mayuri wears face paint except when he is bathing, revealing blue hair and somewhat tanned skin. He created a black cross upon the center of his face covering everything but his nose and a small portion of his lower chin with the face paint. He wears short and round but wide ear attachments, his chin has a long golden attachment reminiscent of an Egyptian Pharaoh beard, his teeth are golden color, and he wears a golden frame around his face. His hair is also styled into "horns," that slope down from the top of his head and frame his face, which when viewed from the front looks much like a Pharaoh's crown. Given his habit of changing his appearance, this wardrobe will likely not last.
Mayuri is a stereotype mad scientist who loves nothing more than subjecting both enemies and allies to horrible experimentation to sate his insidious curiosity. His science ethics are nonexistent, as he will do anything to further his own knowledge.
Mayuri is also extremely brutal, cruel, and sadistic, though also seems to be rather charismatic, as his subordinates are exceptionally loyal to him. He also thinks rather highly of himself, though unlike Szayel, he doesn't see himself as a "perfect" being and, in fact, scorns the very idea of perfection. Aside from that, Mayuri's only (remotely) redeeming quality is that he doesn't treat his own body any better than that of his test subjects most of the time.
Not much is known about Mayuri's past, but at some point he was sent to the Maggot's Nest for unknown reasons. He was eventually released by Kisuke Urahara, who was Captain of the 12th Division at the time, and was made 3rd Seat of the division. Some time after Urahara and his lieutenant, Hiyori Sarugaki, were forced into exile by Sosuke Aizen, Mayuri was promoted to the capatincy of his division. At some point, he created an artificial doll whom he christened Nemu Kurotsuchi, who became his lieutenant.
Mayuri played a large role in the genocide of the genocide of the Quincies, killing and experimenting on many of them, including the grandfather of Uryu Ishida, who has harbored a grudge against Mayuri ever since he learned this.
