Dexter's Laboratory (commonly abbreviated as
Dexter's Lab) is an American
comic science fiction animated television series created by
Genndy Tartakovsky for
Cartoon Network, and the first of the network's
Cartoon Cartoons. The series follows Dexter, a boy-genius and inventor with a secret
laboratory, who constantly battles his sister Dee Dee in an attempt to keep her out of the lab. He also engages in a bitter rivalry with his neighbor and fellow-genius Mandark. The first two seasons contained additional segments:
Dial M for Monkey, which focuses on Dexter's pet lab-monkey/
superhero, and
The Justice Friends, about a trio of superheroes who share an apartment.
