Romulus and Remus
Twin demigod founders of Rome. They were fathered by Mars and mothered by a princess who had been forced into chastity. As punishment for her apparent breaking of her vows, she was forced to abandon Romulus and Remus in the River Tiber. They survived and were suckled by a she-wolf. Romulus later killed Remus when they were arguing over where Rome should be founded. Sounds like a natural leader.
