 If you ever meet Dexter, you d probably notice a few things about him: he speaks with an Eastern-European accent, wears a labcoat, and happens to be a boy-genius with an amazing laboratory in his bedroom! The show follows Dexter s adventures, in and out of the lab, as he copes with his crazy parents (who are completely oblivous to their son s high IQ and laboratory), fights with his sister DeeDee (who sees the lab as her own playground and never wants to leave), and battles his arch-nemesis Mandark (who also possess an impressive laboratory).
