His bloody reign culminates in a battle against Malcolm and the English forces.

Banquo A fellow-captain and companion of Macbeth, who also receives a prophecy from the Witches: that his children will one day succeed to the throne of Scotland. This information is sufficient to spell his death at the hands of the resentful Macbeth, who is later haunted by Banquo's ghost.
Duncan King of Scotland. His victories against rebellious kinsmen and the Norwegians have made him a popular and honored king. His decision to pass the kingdom to his son Malcolm provokes his untimely death at the hands of Macbeth.

Donalbain and Malcolm Duncan's two sons. Fearful of implication in their father's murder, they flee Scotland, Donalbain to Ireland and Malcolm to England, where he raises a large army with the intention of toppling the tyrant Macbeth.
