City of Evil (S02E04)

After Thundarr triumphs over him, the malevolent wizard Sarott discovers a laboratory containing the shrunken City of Thieves. Vortak, the city's ruler, offers Sarott unrestricted access to its sophisticated army for the purpose of subjugating humans and other wizards, provided he can return the city to its original size. To accomplish this, Sarott must obtain the Gauntlet of Power, a magical artifact that will amplify his abilities and allow him to enlarge the city.
