General Onox

Onox is a video game character in the The Legend of Zelda: Oracle of Seasons. In the game, he is known as the "General of Darkness". His appearance is strongly similar to the Iron Knuckles of Ocarina of Time and Majora's Mask, and has a cone-shaped mask/helmet like Zant from Twilight Princess. It is said his evil causes the very ground he steps on to become infertile. At first, he seemed to be the mastermind behind the kidnapping of the Oracle of Seasons, Din, using her power to turn Holodrum into a dying land by throwing the seasons of Holodrum into chaos. Onox appeared as a tornado and kidnapped Din, imprisoning her in a giant crystal, shaped like a giant rupee. He then banished the Temple of Seasons to the subterranean world of Subrosia, heavily damaging it in the process, and the Rod of Seasons lost its power and needed to be re-powered in the temple. In addition, Onox's army, along with various monsters, began to ravage the land. When Link awakens the Maku Tree he gains the ability to penetrate the barrier around Onox's fortress.

Link challenges Onox, and Onox uses a giant flail to attack while his armor protects him from almost all of Link's attacks. When Onox begins to lose the battle, he uses Din (still encased in crystal) as a shield. When defeated, Onox reveals his true form: a demonic armored dragon called the "Dark Dragon". In this form Onox is gigantic and attacks from the air. Link destroys him but, as it turns out, Onox is only gathering the powers of destruction from the dying lands of Holodrum to light the Flame of Destruction for Twinrova as part of their plan to resurrect Ganon.

It should also be noted that Onox has certain Gerudo characteristics, like the clothing under his armor displaying the typical Gerudo patterns and colors, and the Gerudo symbol on his armor (this symbol also appears on the Mirror Shield and blocks in Ocarina of Time when the crescent was removed, and in The Wind Waker in the stained glass window that depicts Nabooru).
