Alexei Luthor of Earth-2

The Earth-2 counterpart of Lex Luthor (DCCPA No. 1, 1982: "Crisis on Three Earths"). Unlike his Earth-1 doppleganger, this Luthor did not meet his Kryptonian archnemesis, the Superman of Earth-2, until they were both adults (Act No. 23, Apr 1940). Also unlike the Earth-1 Luthor, Alexei appears to never have lost his full head of red hair.

Several 1940's tales chronicling Luthor's battles with Superman retroactively show him with a full head of red-hair, such as the All-Star Squadron retelling of a portion of the 1941 Power Stone series of tales. This Luthor bedeviled Superman repeatedly after he was married to Lois Lane, such as when he learned of his adversary's weakness to Kryptonite with the help of Swami Rivers and when he used a "magic" mask and was thwarted by the pair known as Hocus and Pocus.

Decades later, the villain Brainiac murdered Luthor when he disputed taking orders from his Earth-One counterpart.
