Scorpions understandably had a large influence on Egyptian mythology. Ra's daughter, Selket, was associated with the scorpion, which graced her crown. In order to make her son, Horus, strong, Isis exposed him to scorpion stings in the desert. Scorpions were also associated with Set, along with other "wicked" animals of the desert.

There was indeed even a King Scorpion, a predynastic ruler known only from a few surviving artifacts such as the "scorpion mace". It is unclear whether the ruler's name or title were "scorpion" but the kingly figure on the mace is labeled as SQRT along with hieroglyphics of a clearly drawn scorpion sign.
