Duke Sigmund Igthorn

Duke Sigmund Igthorn is the main antagonist of Disney's Gummi Bears and was a renegade noble who sought to take over the world with his army of ogres - he also wanted to use the power of gummi berry juice to aid him in this quest, as the juice gave humans superhuman strength.

Often refered to as "Dukie" by his minions he was short-tempered, power hungry and extremely unpleasant towards almost everyone - he was even cruel to his own minions, ruling over them in the style of a tyrant or dictator: depending on his mood (which, as mentioned above, was almost always bad).
