Edward Groll was a scientist working for LuthorCorp, where he headed the nanotechnology division.
Doctor Edward Groll graduated from Metropolis University. At some point later in his life, he acquired a chair in biophysics at Metropolis University and later was hired to work for LuthorCorp. According to Chloe Sullivan, Doctor Groll had been working for LuthorCorp since the first meteor shower, investigating alien technology. Lana Lang later stated that he had also worked on Project Ares.
Lex Luthor hired Doctor Groll to study and examine the Black Box. He informed Lex that the box was a power source that could provide energy or be used as an extremely destructive weapon. Lana feared that Lionel Luthor would undersell Lex and obtain Groll's information, so she approached Doctor Groll and casually suggested that if he chose to betray Lex, his job and family would be threatened. Doctor Groll later met with Lana, claiming he did not want anything else to do with the black box. He gave Lana all the information he had gathered. He promised never to disclose anything he learned and even warned Lana that Lex has already started military testing on the box. Doctor Groll and his family then went into hiding. This encounter was then photographed by Jimmy Olsen.
Two years later Tess Mercer tracked Doctor Groll down while still in hiding to have him perform tests on the Crystal of Knowledge. He and his team then worked out that the crystal was some sort of alien computer hardrive and planned to open it using a high frequency test but when he performed it, it shot a beam of light into space bringing Maxima to Earth.
Doctor Groll was working on Project Prometheus too, which was a suit designed to allow Lex Luthor to survive after the collapse of the Fortress of Solitude and at the same time grant him powers. Lana learned of this information and agreed with Doctor Groll that Lex would corrupt its power and so they moved the Project to a safe location and Lana became the subject instead. Doctor Groll successfully fused the suit to Lana granting her powers just after Tess broke into the facility and tried to destroy the suit. She and Doctor Groll fought before she shot at him but Lana broke out and stopped the bullet knocking Tess out before leaving at super speed.
The fate of Doctor Groll is unknown.
