Emilio Storme was a scientist at S.T.A.R. Laboratories with a dangerous obsession towards Superman of Earth-One. He first adopted the alter ego of Whirlicane using tornado styled equipment, and later returned with an android with two settings, as Lightning and Thunder. During his second encounter with Superman, Storme's android self destructed seemingly also destroying his master.
His counterpart only went by the name of Lightning Master, his true identity unknown. This hooded scientist in the Metropolis of Earth-Two created a lightning generator and portable lightning gun, which he used to blackmail the city until his schemes were undone by Superman. However, scant weeks later Lightning Master was back, this time sent as an assassin by mastermind Ian Karkull, utilizing a flying saucer equipped with an upgraded version of his generator. And once more, Superman handed him defeat, alongside that hero's allies of the Justice Society in Johnny Thunder and his amazing Thunderbolt.
