MALCOLM: He is the elder son of King Duncan. He first comes across as a weak character and unsure of his power/position after being saved by sergeant. He eventually challenges Macbeth, who murdered his father, Duncan in the middle of the play. Malcolm's sudden reaction of fleeing after the death of his father was a surprise. He seems to lack the experience to make him confident or capable of taking over. It's only when he meets Macduff, who complements him in courage and experience, do we start to see the potential power in Malcolm.
