Demon


 * For the seventh dungeon in The Legend of Zelda, see Demon (Dungeon).

Demons are a race of monstrous, humanoid beings that are usually evil villains. Although not all demons are evil, they still exude a dark aura that attracts monsters and mutates animals. Demons appear many times in different Zelda games.

Unified Timeline
During the Era of the Goddess Hylia, the demon race emerged from the earth, desiring the Triforce, and led by Demise. Demise desired to rule the world with the enormous power the Triforce would grant. Hylia protected the Triforce and took the surviving people to the sky, hiding the Triforce there as well. Hylia and some humans remaining on the surface managed to seal Demise; however, Hylia knew the seal would not last, so she decided to extinguish Demise with the power of the Triforce. However, gods cannot use the power of the Triforce, so she abandoned her status as god to be reborn as a human.

When Hylia was eventually reincarnated as a human (as Princess Zelda), Demise's servant Ghirahim made himself the Demon Lord and set his plans to revive the Demon King in motion. Demons thrived on the surface, so he sent out the demons to locate Hylia's mortal incarnation. Eventually Ghirahim succeeded in reviving Demise; however, Link defeated Demise and the demon race disappeared from the earth.

During the Force Era, demons returned and almost covered the world in darkness. However, the Hero of Men used to the Light Force and the Picori Blade to seal all the demons in a treasure chest, restoring peace. Years later, seeking the Light Force, Vaati opened the treasure chest, accidentally unleashing the demons upon Hyrule once more.

In the Era of the Hero of Time, Ganondorf successfully infiltrated the Sacred Realm and took the Triforce of Power. As the Sacred Realm reflects the heart of the once who takes the Triforce, it became a dark world infested by demons.

Downfall Timeline
In the Era of Light and Dark, Agahnim used his powers to send people to the Dark World. Anyone sent there became a demon, except Link, who possessed the qualities of a hero and instead became a pink bunny (until he found the Moon Pearl, which allowed him to remain in human form in the Dark World). At some point after the defeat of Agahnim, demons infested Labrynna, and attacked Impa shortly before Link awoke to help her. Demons also appeared in the Wind Fish's dream, and attempted to prevent Link from ending the dream by waking the Wind Fish.

Child Timeline
In the Twilight Era, Zant was given magical powers by Ganondorf, which he used to transform the Twili, the inhabitants of the Twilight Realm, into demons. He used this army of demons to attack Hyrule.

In the Shadow Era, a reincarnation of Ganondorf used the Dark Mirror to create demonic copies of Link, known as Shadow Links. If this mirror is used by an evil person, it reflects their heart and creates demons. This new Ganondorf used the power of the Trident to turn the Knights of Hyrule into demons. With the knights now demons and the Royal Jewels turned into gates to the Dark World, demons returned to Hyrule again.

Adult Timeline
In the Era of the Great Sea, the Forsaken Fortress (known as the Demonic Beast Island in Japanese) served as Ganon's base, and was inhabited by many demons.

Transformation
It is possible for demons to turn into humans. In Skyward Sword, Gratitude Crystals can be used to turn Batreaux into a human.

Likewise, humans can turn into demons. Ganondorf, originally a Gerudo, became the demon king after claiming the Triforce of Power during the events of. Anyone Agahnim sent to the Dark World became a demon, except Link, who possessed the qualities of a hero and instead became a pink bunny (until he found the Moon Pearl, which allowed him to remain in human form in the Dark World).

The reincarnation of Ganondorf, also originally a Gerudo, became the demon king after claiming the Trident. This Ganondorf then turned the Knights of Hyrule into demons with the Trident's power.

Other races can also become demons. Vaati, who was originally a Minish, became a demon after draining the Light Force. The Twili were turned into demons by Zant, using the magical powers bestowed upon him by Ganondorf.

Possession
Demons have demonstrated the ability to possess other creatures. Both Ganon and Malladus have possessed Zelda; both have also demonstrated the ability to exist as a disembodied spirit.

Demon Kings
Demise, Ganon, and Malladus have all held the title of demon king. Demon kings are generally depicted as requiring specialized weapons such as Silver Arrows to kill. Rather than getting killed, demon kings can be merely imprisoned. Due to the inability to permanently eliminate the demon king (due to the existence of resurrection) the title is seemingly retained after death.

The Japanese name of the Genie indicates that it is a Demon King as well.
