He is the second spirit ally of Chocolove in the Shaman King franchise.
He is a former shaman who fought in the shaman king fights 1,000 years ago. Hao Asakura is the one who kill him. The Incan people (Dub: Indio) worship his bravery by building a giant Olmec head for him. This causes Pascual to become a kami class spirit.
Pascual Abaj is created by Hiroyuki Takei, and he has no information regarding any inspiration used by the author to create him. He first appears in Shaman King volume 23.
