Gengen Wer was a primeval Egyptian goose god whose onomatopoeic name means Great Honker and who is a force of creative energy.

The imagery is that of the goose carrying the egg from which life emerges. In order to be part of this creation, a continuing cycle in the Egyptian mind, a person in the Underworld might be described as closely guarding or actually being the egg within the Great Honker.

This goose, also called the crackler ('Negeg' in ancient Egyptian) is a form under which Amun can appear as a creator-god.
