Synopsis by Hal Erickson
In this wonderfully Wagnerian episode, Dr. Smith (Jonathan Harris brings the wrath of Valhalla down upon the Robinsons when he steals the gloves and hammer of the Norse god Thor (Bern Hoffman). Now Smith must engage Thor in mortal combat, lest everyone suffer mightily. Amazingly, Thor is vanquished, whereupon the neurotic deity loses all his confidence--leaving Valhalla vulnerable to attack from giant aliens. Sheila Matthews, the wife of series producer Irwin Allen, does a neat comic turn as the "Yo-do-ho"-ing Brynhilda...helmet, sword and all.
