Azure Blue first appeared as an evil miser in The Golden Helmet in Donald Duck Four Color #408. In that story, he was revealed to be a descendant of Olaf the Blue (Vikings discovered America according to that story) and he wanted to find a Golden Helmet so he can be king of North America and make everyone on the continent his slaves, but Donald Duck and his nephews Huey, Dewey and Louie wouldn't let that happen. Azure was assisted by Lawyer Sharky.
