"Demon King" Demise

Demise is the main antagonist of Zelda:Skyward Sword and the overarching antagonist of the series. Otherwise known as the "Demon King", he led an ongoing war in the ancient past against the goddess Hylia before being sealed away all in an effort to take the Triforce and conquer. Despite being sealed he could only take the form as a large mindless entity called the Imprisoned. Years later his servant Ghirahim attempts to revive him by sacrificing Zelda who is part of the bloodline of the goddess. Upon his defeat however he cursed the bloodline of the goddess and the hero to suffer the wrath of his incarnations for all eternity.

Demise is demonic and humanoid in appearance, towering at twice the height of the average adult. His skin has a cracked and rocky texture to it save for his head and neck and his legs. His hair is long and fiery and he wears a long and dark waist skirt.

Demise's power as the king of demons is immeasurable, having the authority to command an entire army of various demons. His greatest weapon is his darkened blade, the polar opposite to the Master Sword itself albeit larger. The sword itself is the true form of Demise's loyal servant Ghirahim who is capable of magical abilities himself. He can also manipulate different forms of magical energies.
