Bio: Edward Lytener was a inventor for LexCorp, who left the
company when there was an investigation. He went out on his own, and
became obsessed with Lois Lane and kidnapped her with his high tech
gadgetry, because she would not notice him. Ultimately he was foiled by
Superman. He escaped from prison, using a new invention which takes
illumination and reflective devices he created to escape. His ulterior
motive in escaping was to gain revenge on Superman for ruining him. He
became Luminus and used a device to turn the sun from yellow to red,
which drains Superman of the source of his powers. This plan was quickly
thwarted and Luminus was back in jail.
