Darden

Darden the Huge is the prince of the Urali Tribe on Eodon, having usurped power through a ploy, forcing his tribe to act hostile and war-like.

Darden had managed to usurp the power in the Urali Tribe by removing the statue of Fabozz to a guarded location, taking away his guidance of the tribe. By holding Fabozz under control, he'd managed to rule as an absolute dictator, forcing the tribe to raids agains the other tribes with threats, that otherwise he'd use Fabozz' control over the Tyrannosaurus to make it eat people of the tribe

The Avatar met him almost right away in Savage Empire, when he kidnapped Aiela before the hero's very eyes. It turned out that he was Aiela's unwanted suitor. The Avatar could do little as Darden, having the advantage of a huge dinosaur, beat him soundly.

Darden locked Aiela into a cell in his tribes' land, trying to buy her love with a big gem. However, she was only disgusted with his offer. When the Avatar came to the rescue, he challenged Darden to a man-to-man duel. Without the support from his men because the Avatar had earlier freed Fabozz, Darden died and the Urali accepted the outcome of the duel eagerly, no one shedding a tear for him.
