Duke Igthorn

Duke Sigmund Igthorn is a character featured in Disney's 1985-91 television series the Adventures of the Gummi Bears. He was voiced by the late Michael Rye.

Background
Duke Sigmund Igthorn was once a knight of Dunwyn who was exiled for conspiring against King Gregor. At an unknown point afterwards, he took control of a rundown castle called Drekmore, and its resident pack of Ogres. Since then, he has constantly conspired to usurp King Gregor and rule Dunwyn himself. He has a brother, Victor Igthorn, who is a brave knight that fights evil. It is implied at several points that Duke Igthorn's father had attempted to control Dunwyn, and raised his son to do the same.

In terms of personality, he is very bad-tempered and a schemer. He is competent enough to gain temporary success in many of his plans, but his success is always short-lived. He later develops a crush on fellow villainess, Lady Bane, but his feelings are unrequited.

Despite the fact that he has many Disney villian attributes, such as being full of himself, Duke Igthorn is also somewhat cunning and a fairly skilled commander. Because of his superior physical strength and command of ogres, the Gummi Bears, as well as King Gregor, consider Igthorn to be a serious threat to their respective homes.

Appearances
Duke Igthorn serves as the series' primary antagonist. He leads a group of Ogres, who are extremely loyal and physically strong, but very stupid. However, Toadwart, a smaller and slightly more intelligent Ogre, serves as his lieutenant.

His introduction to the Gummi Bears and their vast technology has also led him to attempt to assault them in hopes of gaining access to their Gummi Berry juice, which temporarily gives humans super-strength. To this point, many of his plans revolve around capturing the bears and gaining a constant access to their juice. His other schemes are usually ill-fated plans to take over Dunwyn.

In the series finale, Duke Igthorn disappears from his castle for nearly a year. Believing him to be gone, the Gummi Bears send a message to the Great Gummis telling them that it is safe to return. However, Duke Igthorn suddenly arrives, destroys Gummi Glen, and captures Dunwyn. However, the Gummis are able to stop him.
