Dexter's Laboratory has ended after 4 seasons.
Dexter's Laboratory has finished its run on Cartoon Network, wrapping up after 4 seasons and 220 episodes since 1996. It is listed as ended rather than cancelled, meaning it concluded as planned rather than being pulled mid-story.
Dexter, a boy-genius with a secret laboratory, constantly battles his sister Dee Dee, who always gains access despite his best efforts to keep her out, as well as his arch-rival and neighbor, Mandark.
