Giygas

Giygas (ギーグ�Gīgu) is a character in Mother and EarthBound. Known as both the "Embodiment of Evil" and the "Universal Cosmic Destroyer," Giygas is an evil alien who intends to sentence all of reality to the horror of infinite darkness. With an army of Starmen, Octobots and other deadly war machines, Giygas also uses his immense power to influence certain Earthlings to assist him, such as Pokey Minch and Geldegarde Monotoli. In EarthBound, most of Giygas's operations take place in the city of Fourside.

Biography
Giygas was raised from infancy by a woman named Maria and her husband George, both of whom were abducted from Earth in 1909. During this time, George studied the aliens' PSI powers without their permission, culminating with his escape back to Earth. Once he matured, Giygas was tasked by his people to ensure that PSI never spread onto Earth. However, Giygas did not want to betray those who raised him, particularly Maria. In the end, he was forced to detach himself from Maria and begin preparations for the invasion of Earth.

Eighty years later the invasion begins, although Giygas is confronted by the great-grandson of Maria and George, Ninten, and his companions. Before the two can fight, Giygas, still hurt by the loss of Maria, offers Ninten to come with him back to his home planet, signifying that the only thing he really wants in life is companionship. Ninten declines this offer though, and Giygas is forced to attack. Ninten then sings a song once shared between Maria and Giygas, and the comforting memories he had suppressed weakens Giygas. The latter surrenders and retreats, but not without promising to take revenge on Ninten.

Giygas returns to Earth many years later as the primary antagonist of EarthBound, though he vastly differs from his appearance in Mother. In the time between invasions, Giygas gains such tremendous evil power that it destroys his entire being, including his mind, causing him to become undefinable by human standards. As such, Giygas manifests as what can only be described as pure evil; in Pokey Minch's words, "he is the Evil Power." Due to the loss of his mind, Giygas becomes irrational and incapable of thought. In the final battle, Pokey attests that Giygas isn't aware of himself or what he is doing, referring to him as "an all-mighty idiot." This is highly reminiscent of the Lovecraftian god Azathoth, who is referred to as the "Blind Idiot God."

Now wielding a vast cosmic power which he is unable to control, Giygas becomes a threat to the existence of the universe itself. Ten years after the beginning of EarthBound, Giygas initiates the apocalypse. The only known being who manages to escape destruction is an alien insectoid named Buzz Buzz, who travels back in time ten years and warns Ness of the impending catastrophe. Ness is given the Sound stone and instructed to record the Eight Melodies in order to gain the power of the Earth and be strong enough to face Giygas.

In Ness' present-day, Giygas' influence is seen throughout the Earth, mainly in the form of enemies that Ness encounters. Now existing as the whole of evil power in the universe, Giygas is able to manipulate the evil in the minds of living beings, both human and animal, and he can apparently manipulate even the forms of inanimate objects.

In the final battle, Giygas is held within the Devil's Machine, a machine created to contain Giygas' tremendous power. During the battle Pokey shuts the machine off, causing all of Giygas' power to be unleashed; an event that surrounds the four children in a chaotic, bizarre dimension of darkness. His attacks are random and incomprehensible, and his speech is erratic and mindless. He is eventually defeated after Paula calls out to the people of the Earth to pray (including the player), and the combined prayers reach Giygas and exploit his weakness, which turns out to be human emotions (possibly due to his loss of Maria). He fades into nothingness, and his apocalyptic future is erased.
