Spirou authors made them the flagship team to a whole new school of young, likeminded artists, such as Didier Conrad, Bernard Hislaire or Frank Le Gall, who had illustrious careers of their own. For a time, Spirou also acted as a side character in Frank Pé's short-lived absurd humor strip (originally published in the weekly magazine). With La jeunesse de Spirou (1987), Tome and Janry set out to imagine Spirou's youth. This idea was later developed into a spin-off series, Le Petit Spirou ("Young Spirou"), which details the antics of the character as an elementary school boy. A lot of the gags center around the character's interest in the opposite sex. It is generally acknowledged, however, that the Petit Spirou has little in common, psychologically speaking, with the adult character.

At any rate, the controversy caused Tome and Janry to concentrate on , and stop making albums in the main series. in the 21st century Morvan and Munuera After a six-year break, which only saw the publication of , a Spirou spoof by Lewis Trondheim not included in the official series (but which received Dupuis' approval), the series went back to a more classical storytelling mode with seasoned cartoonists Jean-David Morvan (writing) and José-Luis Munuera (art). The latter kept close to the spirit of Franquin's graphical style, while bringing its own touch of manga-inspired modernism. Morvan and Munuera's Spirou is partly remarkable in that it uses background elements and secondary characters from the whole history of the title, and not just from Franquin's period.
