Shigesato Itoi
Giygas, also known as Giegue, and 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 of "Mother" and its sequel, "EarthBound". He invades Earth in an attempt to wipe out humanity in "Mother", and returns in "EarthBound" where he conquers the world and sends his forces into the past to ensure that protagonist Ness could not defeat 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.
