hera
Hera is the wife of Zeus. She is also one of his three sisters. She has a jealous and vengeful nature against Zeus' lovers and offspring, but also against mortals who crossed her. She threw Hephaestus down to earth because he was ugly. Hera tried to kill Heracles by sending two serpents to strangle him while Heracles is still a baby. She also sent a crab to bite Heracles' feet in order to distract him, during his fight with the Hydra. Hera tried to prevent Leto from giving birth to her children but she did not know that Leto gave birth to her children on the floating island of Delos. Hera also forced Semele to see Zeus in his true form, which resulted in Zeus killing Semele with his own thunder and lightning by accident. Hera's sacred animals were the cow, lion and peacock. Hera is also sometimes kind to other gods and mortals on certain occasions.
