The primary antagonist of MOTHER/EarthBound Beginnings and its' Super Nintendo/Super Famicom successor, MOTHER 2/EarthBound, in which he is known as Giygas. In Japan, he is referred to as Gyiyg. Giegue was raised by a woman named Maria, who was abducted from Earth alongside her husband George by Giegue's alien race in the early 1900s. George studied the aliens' psychic powers, known as PSI, without permission and escaped to Earth. Giegue, when matured, was tasked by his people to lead an invasion of Earth to make sure PSI never spread on Earth. However, Giegue did not want to betray those who raised him, especially Maria. Yet, he forced himself to detach his emotions from his caretaker and prepared an invasion 80 years later. In the end, his (first) invasion was thwarted by Ninten (a descendant of George and Maria) and his allies, singing a lullaby which Maria had sung to Giegue many years ago, causing enough emotional stress to make the extraterrestrial turn tail, albeit promising to return someday. Requires the Renamon headmod and the Android 21 tail.
