|The series takes place in the Middle Ages and centers around a powerful yet cowardly barbarian named Dave. Together with his sisters Fang and Candy and their Uncle Oswidge, the family is in temporary rule of the fictitious land of Udrogoth. The real king and queen, Throktar and Glimia, are away "fighting evil" (though they make occasional appearances via crystal ball) and have left Candy in charge.
Much like its predecessors The Flintstones and the short-lived The Roman Hollidays, "Dave the Barbarian" juxtaposes both the ancient and modern. Candy, for example, shops in the local mall and uses the crystal ball for online shopping sprees. Occasionally, the series even drops the so-called "fourth wall" with a character directly addressing the audience.
