About Giygas

Giygas, also known as Giegue in EarthBound Beginnings, and Gyiyg in Japan, is a fictional alien character in the Mother video game series by Nintendo, created by Shigesato Itoi. The character serves as the main antagonist and final boss of EarthBound Beginnings and its sequel, EarthBound. In the series, he invades Earth in an attempt to wipe out humanity in EarthBound Beginnings, and returns in EarthBound where he conquers the world and sends his forces into the past to prevent protagonist Ness from defeating him. The battle against Giygas, which depicts him in turmoil, drew inspiration from a Japanese film which traumatized Itoi as a child. He has received positive reception with critics referring to his battle as one of the creepiest in video games, and considered one of the greatest and most iconic video game antagonists of all time.
