Demise

Demise is the first ever villain in the Zelda timeline. He is after the Triforce to rule the world, but was sealed temporarily by Hylia in a brutal battle. In The Legend Of Zelda Skyward Sword the seal starts to give away and a creature called The Imprisoned starts to come out. After Link goes to the Temple in the desert he arrives at the Sealed Grounds and seals The Imprisoned for a certain amount of time. Throughout the game Link seals the Imprisoned two more times. After that Zelda awakens from her 1000 year sleep and gets captured by Ghirahim and brought to the past to revive Demise. Link goes to the past and Ghirihim brings back Demise by using Zelda's soul and Hylia's power to revive Demise. Ghirihim turns into a weapon and is used by Demise. Demise then goes into another dimension to wait for Link to battle him. Link goes into the portal,fights an epic battle with Demise, and destroys him with a finishing blow. When Demise is fading away he tells Link that everyone that shares the blood of him will be haunted by his power forever. This is how Ganondorf and all of the other evil creatures were created to torment Link's descendants.
