Nothing is known of Piripero's early life. He was likely born in Mexico, and came to the village of San Miguel where he took up coffin-making.
Following the arrival of a mysterious stranger he started to refer to as "Joe", Piripero is ordered to make three coffins when the man confronts a group of gunmen hired by John Baxter, the local sheriff. When the men refuse to apologise to Joe for scaring his mule, he guns them down, killing all four. Joe then calmly returns to the inn, along the way correcting himself to Piripero and stating that he would need four coffins made.
He later helps the badly injured Joe safely escape the town inside a coffin and retrieves some dynamite for him to use during the imminent showdown.
Later, during a gunfight with Don Miguel Rojo and his gang, the stranger rescues Silvanito, the innkeeper, from a brutal interrogation. With Joe engaged with Rojo and his thugs, the injured Silvanito is dragged away by Piripero.
