Years ago, before you were born, your mother and Zeus had a one-night stand, which resulted in you.

However, as a result of Hera's hatred, your mother hid you from the gods and the world itself. From a young age, she knew you weren't like other kids. You were special. But, they would see you as a monster. Your mother didn't want that. You had (whatever powers you want <3) but weren't allowed to use them in case the gods found out

However. He knew. Zeus somehow knew.
