Which Scooby-Doo series introduced the gang’s early childhood versions?

A Pup Named Scooby-Doo introduced childhood versions of the Scooby-Doo gang.

The animated series premiered in 1988 and reimagined Fred, Daphne, Velma, Shaggy, and Scooby as young mystery-solvers. Their designs were more stylized and deliberately cartoonish than those used in the original 1969 show, while the stories retained the group’s interest in strange cases.

The series also gave the characters younger versions of traits associated with their older portrayals. Fred remains enthusiastic about solving mysteries, Velma is highly analytical, Daphne is confident, and Shaggy and Scooby continue to be easily frightened and food-focused.

A Pup Named Scooby-Doo is not the same as later productions that show the characters as teenagers or adults. Its central premise is specifically a childhood reimagining. The show ran for four seasons and was produced by Hanna-Barbera.
