Duke Igthorn was once a knight of Dunwyn. At some point prior to the series, he was banished from the kingdom for staging a military coup against King Gregor. Afterwards, Duke Igthorn moved to Drekmore, a dangerous land bordering Dunwyn. There he took command of the native Ogres and occupies a rundown castle called Castle Drekmore and began scheming to get revenge against Dunwyn. His first attempt was through a giant catapult, which was foiled by Cavin and the Gummi Bears. However, because of the Gummi Bears' intervention, Duke Igthorn came to know of the Gummi Bears and their juice. From there on, he would frequently attempt to gain access to the potion because of the vast strength it would give humans, which would presumably assist in his schemes. Despite occasional bumbling and a slight streak of cowardice, Igthorn is a valid threat to both Gummi Glen and the Kingdom of Dunwyn.
