Description
Peyote Diaz, born September 11, 1970, in Oaxaca, Mexico, is the son of a Spanish exorcist and an Aztec priestess. Before embracing shamanism, he performed with Mexico's finest mariachi band, notorious for violent brawls. All other members met violent ends: Carlos and Juan died in a saloon shooting, while Antonio, Jose, Pancho, Miguel, and Zapata perished in separate fights. Alone, Peyote encountered young Asakura Hao in a bar. Initially intrigued by Hao's shamanic power, Peyote ultimately felt drawn to the darkness within Hao and became his follower, seeking purpose. He was fully integrated into Hao's group approximately five years before the Shaman Fight, advocating their self-sufficient, non-materialistic way of life.

His typical attire includes a green-and-orange Mexican serape, a sombrero, jet goggles, and a black veil decorated with bones and a skull covering his mouth. Long green hair grows from the top of his otherwise bald head, often draped to one side. He wears knee and knuckle plates labeled "Hao" and carries a guitarrón guitar. After Hao resurrects him, Peyote's appearance deteriorates: he neglects hygiene, becomes emaciated, loses teeth, and sports an unkempt beard and hair. New tattoos appear: a half-sleeve depicting Hao overlooking the heavens and a misspelled "friend" (友ださ instead of 友だち). Surgical scars also become visible around his scalp.

Initially, Peyote demonstrates absolute loyalty to Hao, executing orders ruthlessly, such as using unconscious teammates as mediums in battle. He believes fighters need a clear purpose to avoid becoming "losers." However, repeated failures in the Shaman Fight and Hao's perceived indifference erode his faith. He begins questioning Hao's motives and the morality of their missions. Post-tournament, he becomes aimless and suicidal, admitting to suicide attempts to "serve Hao again." His emotional conflict peaks when he declares his deep love for Hao makes him the one who "hates him the most."

As a shaman, Peyote's furyoku starts at 3,000, later rising to 32,000. His primary weapon is his guitar, manipulating souls through vibration. His guardian ghosts are his deceased mariachi band. His Oversoul techniques channel Antonio, Jose, Pancho, Miguel, and Zapata into Calavera dolls for offense, while Carlos and Juan possess human bodies (like his teammates BoZ) for defense, often forming cactus-like weapons. His strongest Oversoul, "Grande Fantasma," uses a large Spanish Fallas doll for powerful stealth attacks despite its size. Post-resurrection, Hao grants him the spirit Santa Muerte to prevent suicide; Santa Muerte acts protectively and enables "New Trance."

Leading Team "Tsuchi-Gumi" with BoZ in the Shaman Fight, Peyote controls BoZ's unconscious bodies via Carlos and Juan and attacks with Calavera dolls in the second round against Team "The Ren." Chocolove McDonnell disrupts his Oversoul by making the spirits laugh, allowing Ren Tao to defeat him. Eliminated, Peyote joins missions targeting Team "The Ren." Leveraging Nichrom's revelation about Chrom's death, he impales Ren with Grande Fantasma – a fatal blow reversed by Yoh Asakura. Peyote later attacks Yoh's group at a hospital, but Ryu restrains him, forcing his retreat via Gandhara intervention.

Post-tournament, Peyote openly doubts Hao's vision during a mission against warships, blaming their failures on Hao. When Mohamed Tabarsi warns him about Hao's mind-reading, Peyote's Grande Fantasma kills Zang-Ching. He murders Bill Burton and Brocken Meyer, claiming it would "strengthen" them. As Kanna, Matilda, and Marion attempt a counter-curse, Tamurazaki shoots them. Peyote intercepts the attack, revealing Hao knew of their dissent, and uses his Oversoul to crush himself and the three women, ensuring their permanent death through irreparable bodily damage. In the 2001 anime adaptation, Peyote remains loyal to Hao throughout, never questioning or betraying the group.

His name references the peyote cactus, native to Mexico and used in traditional rituals. He frequently uses the Spanish phrase "Eres correcto" (intending agreement, though grammatically inaccurate). The surname "Diaz" means "son of Diego" in Spanish.
