Onox

Onox is one of the main antagonists of the video-game The Legend of Zelda:Oracle of Seasons.

Onox resembles Iron Knuckle and is one of the last bosses encountered in the game, capable of taking a dark dragon form - his goal in the game is to ruin the land and he often refered to himself as a General of Darkness.

Though Onox is really a Dark Dragon, he usually takes the form of a male Gerudo, possibly to show his loyalty to Ganon.
