Did you know

In Latin, alter ego literally means "second I". An alter ego can be thought of as a person's clone or second self.[eg Tom and Arfur ]A professional alter ego might be a trusted aide who knows exactly what the boss[Mac} wants done. A personal alter ego might be a close friend who is almost like a twin. Alter ego can also refer to the second, hidden side of one's own self. In Robert Louis Stevenson's classic The Strange Case of Doctor Jekyll and Mr. Hyde, Dr. Jekyll is a good-hearted, honourable man; but after taking a potion, his alter ego, the loathsome and diabolical Mr. Hyde, takes over his personality.
