Alex Raymond's comic strip
Dale Arden is introduced in the first Flash Gordon story, July 7, 1934, as simply "a passenger" on the plane Flash is flying on. After the plane is hit by a meteor, Flash saves Dale by parachuting to the ground. The two are then abducted by Dr. Zarkov, who takes them on his rocket to the planet Mongo. In the 1930s comic strips, Dale often comes into conflict with other female characters who desire Flash romantically (such as Princess Aura and Queen Azura).
