In Abrahamic tradition, Gog and Magog appear in the Hebrew Bible, often known as the Old Testament, and Quran 21:96 as individuals, tribes or lands. In Ezekiel 38, Gog is an individual and Magog is his land, in Genesis 10 Magog is a man, but no Gog is mentioned; and centuries later Jewish tradition changed Ezekiel's "Gog from Magog" into "Gog and Magog," which is the form in which they appear in the Christian New Testament's Book of Revelation, although there they are peoples rather than individuals. Gog and Magog were the name of ancestors of an unidentified group of peoples.
In English lore, Gog and Magog are giants who are guardian spirits of the city of London. A legend was attached to Gog and Magog by the time of the Roman period, that the Gates of Alexander were erected by Alexander the Great to repel the tribe. After the Roman Empire became Christian, Ambrose identified Gog with the Goths, Jerome with the Scythians and Jordanes said that Goths, Scythians and Amazons were all the same; he also cited Alexander's gates in the Caucasus.
"A giant said to have lived in ancient England. It is said he could rip a tree from its roots as easily as an ordinary man could rip a vegetable from the ground. He fought Corineus, the legendary hero of Cornwall."

"A giant believed to have lived on the island of Britain in prehistoric times. His body was so huge that he could destroy a sailing ship with a swing of his arm. He repelled all who invaded the island, but was defeated by Brutus of Troy."
—Shin Megami Tensei V: Vengeance lore
Gogmagog is a punishing enemy that is exclusive to the Canon of Vengeance, found in the Shinjuku area of Da'at, within a basin near the Shinjuku Gyoen leyline fount. Should the Nahobino step into the basin, Gogmagog will react by emitting gravitational waves to pull the Nahobino into itself. Gogmagog is the target of a subquest issued by a Throne from Bethel, titled "As God Wills," where said Throne requests assistance from the Nahobino in slaying Gogmagog. Completing the quest unlocks Gogmagog for fusion.
However, in the Canon of Creation, Gogmagog is not a locked fusion, and so can be fused at the Nahobino's pleasure or can be found roaming as wild demon encounters in the Taito region, specifically in Komagata.
