The goddess that didn't sprang out of Zeus' head was Athena. Earlier, Zeus had swallowed his wife Metis because he was told that if Metis had a son, that the son would overthrow his father. Later, Zeus got a pounding headache. He told Hephaestus (his son by Hera) to cut open Zeus' head. Then, Athena jumped out, in full armor and ready for a battle.
Zeus and Metis were going to have a daughter or son. He found out that if he had a son, his son would overthrow him like Zeus did to Kronos. Zeus tricked Metis into turning in to a fly by saying that she was too powerful to do so. He then ate Metis. Later, he had a pain in his head and told his cupbearer to take an ax and split Zeus's head. Athena sprang out of him in full battle armor.
