The Doctor is the LuthorCorp scientist behind Leviathan.
Season Five[]
The Doctor performed tests of Leviathan in Crater Lake (without public knowledge). While the tests proved successful, she expressed concern about the harm Leviathan does to marine life, which were dismissed by Lex Luthor. The Doctor later oversaw the Leviathan demonstration for the Pentagon, where she saw the weapon seemingly self-destruct.
Notes[]
- The character wears an I.D. badge (providing the character with a canonical name), during the Pentagon demonstration. However, the camera never gets close enough for the name on it to be readable. Lex Luthor only refers to the character as "Doctor".
- While the Doctor expresses concern about marine life, she appears to have no issues with secretly testing an experimental weapon in Crater Lake, a popular swimming spot for local youth.
