Athena and Her Half Brother Porus...?

[.xAlyssa.]

I was assigned a project in English.... We are working on Greek Mythology and I have to write a descriptive paragraph on the Goddess Athena. I just found out that she had a half brother called Porus... Apparently he is the Greek God of Expediency. Just wanted to know if this was true. Thanks:] Please let me know as fast as possible.

Porus was Athena's half-brother because he was the son of Metis alone while Athena was the daughter of Zeus and Metis.
