S1·E10 Azoth the Avenger is a Friend of Mine

A bullied boy, Craig, deciphers a coded message that allows him to summon his comic book hero, Azoth the Avenger. This long-haired Conan-like barbarian beats up the bullies that plague Craig, but is defenseless against his abusive father. Azoth returns to whence he came but inspires Craig to take a stand against his father - intoning the same spell as before and sending his father...somewhere, leaving him and his mother in peace.
