Malignant Mental Masterminds battle the Sandmen

The lone survivor of an Allied attack on his location during World War II, the kamikaze squadron leader was operated on by surgeons who crafted advanced electronics in his brain. Seeking revenge for the defeat experienced by his native Japan, this man adopted the alias of General Electric and used electronic dolls and, later, video games to infilitrate the American military. This led to confrontations with first Garrett Sanford aka the Sandman of Earth-One, and later Wonder Woman.  

After the latter defeated the General (as had the former), this brought Wonder Woman to the attention of Sandman. While he attempted to romance her, ultimately the two heroes decided to remain allies, and Sandman later became an honorary member of the Justice League.

Another Asian man, Hiram Gaunt, utilized an electronic device of his own creation to boost his mental capability. As the Answer Man, Gaunt used his telepathic abilities to initiate some robberies with limited success. Ultimately, Gaunt found himself outmatched by the Sandman and Sandy of Earth-Two, who defeated him and sent him to prison.

While the Answer Man never had occasion to face his world's Wonder Woman, she had met her Sandman aka Wesley Dodds when becoming a member of his team, the Justice Society. There never were sparks of romance between the two, who kept their relationship professional during the many years they works together.
