Ivar the Boneless

Ivar the Boneless - Ragnar and Aslaug's fourth and most violent son. A birth defect has rendered his legs useless and left him impotent. Ivar is more unstable than his brothers, sadistic and seemingly narcissistic. While publicly boastful, in private Ivar is deeply insecure about himself and feels unloved by all except his mother Aslaug. When Lagertha kills Aslaug Ivar vows vengence and with the help of Harald and Rollo makes himself king of Kattegat. He is married to his former slave Freydis, who manipulates him and inflates his ego.
