9.) “Alf,” “Consider Me Gone” (1990)

It was enough of a surprise that Alf (voiced by Paul Fusco) was ready to leave the Tanners behind on Earth to go back to his home planet. However, when he got into a spacecraft, it was intercepted by the Alien Task Force, from whom Alf had spent years hiding during his stay on Earth.

However, the show’s writers could not just let him go home in peace, giving him what viewers can only assume was a tragic ending.
