Poseidon enemy

Some of my enemies are my father Cronus my brother Zeus Athena becouse Zeus promised the city of Athens.  Athena is my enemy becouse I remember Athena making a contest ho would each give the people of Athens a gift. Who's ever gift they liked better would get the city of Athens. I gave the people of Athens a salt water spring.Athena gave them an olive tree. And guess ho won Athena. And Zeus becouse he was the god of gods.
