Octavius is
Caesar's nephew and adopted heir. He is young and inexperienced when he returns to Rome as an ally of
Antony after Caesar's death—he protests Antony's plan to betray Lepidus, and he is initially outmaneuvered by
Brutus at Philippi. After the events of the play, however, Octavius eventually overcomes both Lepidus and Antony (as Shakespeare dramatized in his play
Antony and Cleopatra) and rules successfully as Augustus Caesar.
