Serket (or Serqet) was an Egyptian goddess known for her scorpion motif. Originating in the country’s northern region (known as Lower Egypt), she was a protective goddess with healing power against the scorpion’s venom. In some variants of the Osiris story, it is Serket who protects Isis with her scorpions while the latter gives birth to Horus. Other roles Serket performed in Egyptian mythology were watching over the souls of the death and punishing evildoers with scorpion stings.
Of course, my portrayal of Serket as a woman with a scorpion’s body is inspired in large part by the character of the Scorpion King (played by Dwayne “The Rock” Johnson) in the second Mummy movie with Brendan Fraser. You have to admit, the scorpion-centaur look is kinda neat.
