The name came from the Hebrew word that directly means "cocoon" or idiomatically meaning "fool", but other sources tell that it came from the word gelem which means "raw material". The word golem is used in the Bible to refer to an embryonic or incomplete substance: Psalm 139:16 uses the word גלמי, meaning my unshaped form, which then passes into Yiddish as goylem. The Mishnah uses the term for an uncultivated person ("Seven characteristics are in an uncultivated person, and seven in a learned one", Pirkei Avot 5:9 in the Hebrew text, varies in English translations).

They draw energy from the men to sustain themselves, often until the point of exhaustion or death of the victim.
Beowulf - Beowulf is the Geatish hero of the Old English poem of the same name. This poem is famous for being the oldest known piece of English literature. It appears that Beowulf and Geryon had their names switched, as Devil May Cry 3 Beowulf more closely resembles the description of Geryon given in the Divine Comedy, while the legendary Beowulf would be more similar to the Devil May Cry 3 Geryon's rider. In the Divine Comedy, Geryon was a chthonic demon representing violence and fraud which had the body of a winged dragon, the arms of a lion, the tail of a scorpion, and the face of an honest man. Dante and Vergil force it to bear them further into Hell, and Vergil protects Dante by sitting between Dante and the beast's deadly tail. It is also possible that the Devil May Cry 3 Beowulf is based upon the literary Beowulf's main foe, Grendel. In particular, Grendel's right arm was ripped off by Beowulf to be used as a trophy, similar to how Beowulf's arms and legs make up its Devil Arm form. The design for Devil May Cry 3 Beowulf could also be based on Pazuzu, a Sumerian wind demon with the body of a man, the head of a dog, the legs of an eagle, two pairs of wings, a scorpion's tail, and a serpentine penis.
