Zeus had swallowed Metis too late, as she had already conceived. Athena grew inside Zeus until one day Zeus was struck with a terrible headache. Such was the pressure and the pain, that Zeus ordered one of the gods (as to which, it varies) to cleave his head with an axe. (don't ask me why they thought this was a good idea. The gods are weird.) When they did, Athena sprung from Zeus' head fully formed and armed .
