Humberto de la Torres was the son of Spanish farmer Ramon de la Torres and his wife Emelita. Humberto loved to read from his favorite book, Don Quixote by Miguel de Cervantes. When a three-man biker gang consisting of Black, Red & Yellow tried to scare the De La Torres family off their land, they found protection from the ghosts of Don Quixote and Sancho Panza. Eventually the Ghostbusters and the literary ghosts teamed up to defeat the biker gang, who revealed themselves to be working for Sandoval. The businessman was after the cover mine hidden beneath the De la Torres' land.
