What is the name of the main villain in Skyward Sword? Demise. Demise is the Demon King and the primary antagonist of The Legend of Zelda: Skyward Sword. Long before the game's present-day story, he leads an army of monsters in an attempt to seize the Triforce and claim its power.

The Goddess Hylia gathers the surviving people and sends them into the sky, creating Skyloft, while she battles Demise on the surface. Although she succeeds in sealing him, the seal weakens over time. In the game's present, Demise repeatedly attempts to escape in the form of the Imprisoned, a massive creature that attacks the Sealed Temple.

Link ultimately obtains the Triforce and uses it to destroy Demise's physical form. However, Demise's remaining essence is confronted in the past, where Link defeats him in a sword duel. Before his defeat, Demise places a curse on Link and Zelda's bloodlines, saying his hatred will continue to be reincarnated. Ghirahim is an important secondary antagonist and servant of Demise, but he is not the game's main villain.
