In the “Dragon Ball” series, Piccolo does not have any biological children.
As a Namekian, Piccolo’s race has the ability to reproduce asexually, but he himself has not produced any offspring. Despite this, Piccolo takes on a crucial mentor and fatherly role, especially with Gohan.
Their relationship between them starts when Piccolo trains Gohan to prepare for the fight against the Saiyans, and over time, it evolves into a deep and meaningful bond. Piccolo’s guidance helps Gohan unlock his potential and grow stronger, showcasing Piccolo’s caring and protective nature.
This father-figure role is a testament to Piccolo’s character development from a once villainous figure to a beloved mentor and protector within the “Dragon Ball” universe.
