Metis was the first wife of Zeus, the king of the gods in Greek mythology. According to a prophecy, Metis would bear two children, the first being Athena, while the second one, a son, would be so powerful that he would overthrow Zeus.

This prophecy worried Zeus, so he tricked Metis into turning herself into a fly and then swallowed her whole.

However, Metis was already pregnant with Athena at the time. She continued to live inside Zeus's head and helped him to rule the world. One day, Zeus experienced a terrible headache. Hephaestus, the god of fire and metalworking, split Zeus's head open with an axe, and Athena emerged fully grown and armed.

In Simanity, it wasn't Zeus who tries to get rid of her, but Hera.
