The Main Family:
* Hagar: The titular character, a Viking chieftain who is known for his gruff demeanor, love of ale, and frequent attempts to conquer new lands. He's often portrayed as incompetent and prone to making bad decisions, but he also has a good heart and cares deeply for his family.
* Helga: Hagar's wife, a strong-willed and quick-witted woman who often uses her intelligence to outsmart her husband. She is known for her sharp tongue and her ability to hold her own in a fight.
* Eddie: Hagar and Helga's son, a young boy who is often the butt of his father's jokes and pranks. He is a bit of a scaredy-cat but also possesses a strong sense of loyalty and compassion.
* Happy: The family's pet pig, who is often a source of comedic relief. Happy is known for his gluttony and his tendency to get into trouble.

* Grimnir: Another of Hagar's companions, often depicted as a cunning and ambitious schemer. He frequently tries to undermine Hagar's authority and take over his leadership position.
* King Borric: The ruler of Hagar's land, a generally wise and benevolent king who often tries to rein in Hagar's more outlandish schemes.
