one of the 20th century's first metahumans. This led the young hero on a quest to learn of his father's fate. After having read his father's diary, Arn turned to the government's secret Project M, demanding to know the location of the "Dinosaur Island" mentioned in his father's diary. There he met Georgia Challenger, who led him instead to Maple White Land in South America. Surprisingly they found Arn's father, Hugo Danner, who had spawned a new band of "offspring", the Sons of Dawn. Danner used his father's formula to bestow powers on these Sons of Dawn and mentioned that the creators of the villain Übermensch had also stolen that formula. Arn was forced to oppose his father when Danner ordered the Sons of Dawn to attack a Brazilian city. The combined might of the All-Star Squadron defeated the Sons of Dawn and Danner was killed.

The couple eventually married and on numerous missions came up against his WWII Nazi nemesis, Baron Blitzkrieg (calling himself simply The Baron and working for the Soviets). When the couple bore a second child, it was kidnapped by the Baron when Sandra was on a mission in Communist Poland. The child was (and still is) assumed killed at the time. The couple gradually grew apart and sometime in the 1960s, Phantom Lady disappeared while on a covert mission for Argent. Though Munro later discovered she was alive, the two were never reunited. Munro settled in Florida with his friend, Roy Lincoln (the Human Bomb). There he eventually met the young hero Grant Emerson (Damage). Munro helped Emerson search for the identity of his biological parents. For a time, it appeared that Grant might be Arn and Sandra's lost child. Eventually they
