The Red Panzer appears in 1976 suprised to see such a young Wonder Woman. Wonder Woman tags along as he retreats to the past, neither realizing that he's journed from Earth-2 to Earth-1 and back again! On Earth-2, in the 1940s, E-1 WW and E-2 WW meet for the first time. After helping E-1 Wonder Woman return to her time and space, the Red Panzer returns to attack E-2 Wonder Woman.
After the Earth-1 Wonder Woman returns home, this series begins to follow the World War II adventures of the Earth-2 Wonder Woman. These adventures continue through Wonder Woman #243.
