Dexter is the titular main protagonist of the classic Cartoon Network series Dexter's Laboratory. He is a brilliant child prodigy whose laboratory often is destroyed by his clumsy and not-too-bright older sister Dee Dee. He has a rival named Mandark, who is possibly more intelligent than Dexter is, although that's not what Dexter really thinks.
