Johnny Test (also known as Johnny Testicles) is an annoying bratty half-pint who is the star of the god-awful Johnny Test. He is basically a retarded version of Dexter and Jimmy Neutron who does many stupid experiments, and they hate him for that. Johnny Test is also a member of The Barney Bunch and The Brat Family.
