Dr. Randall appears exclusively in the "Crystal Pharaoh" episode of the *Cleopatra D.C.* OVA series as an antagonist threatening Cleopatra Corns and her associates. He demands a diamond in exchange for a captive’s safe return, warning: "if you want to get her back safely, give us the diamond. Otherwise..." His goal is to weaponize the diamond into an optical weapon, declaring his intent to make the Corns group fear him and revealing that "nobody knows this will be an optical weapon!" He describes the diamond as a "Lethal Weapon" capable of burning the world, with a mysterious woman collaborator reinforcing the global threat by stating it will affect "not just the Corns, but the world!" Dr. Randall displays a mocking demeanor, taunting Cleopatra with the phrase "Energetic and charming, as always..." His background, affiliations beyond the conflict, and development remain confined to this episode.
