Dr. Robert Bethany was a physician at the Smallville Medical Center in the WB/CW TV series Smallville. He served as the main antagonist in the Season Six episode "Freak".
He was portrayed by Adrian Hough who voiced Haytham Kenway in Assassin's Creed III.
Robert Bethany was a doctor working for Lex Luthor who was abducting and experimenting on kryptonite-infected individuals around Smallville. In order to locate meteor-infected people, Dr. Bethany exploited Tobias Rice, a young man who had been blinded during the second Smallville meteor shower. The incident had left Tobias with the ability to sense other people who had also been infected by the meteor rocks.
Due to Tobias' gift, Bethany located and abducted numerous individuals and conducted experiments on them, extracting their DNA before erasing their memories of the abduction. Dr. Bethany arrived at the bowling alley guiding Tobias who persuaded him to take his glasses off and Tobias points directly at Daniel Kim, a bowling employee, saying he's "one".
Dr. Bethany went to the Luthor Mansion to talk to Lex saying Tobias was getting impatient waiting for a cornea transplant and knew Lex was delaying the surgery because it would take away Tobias' ability. He's certain Tobias will tell someone what he and Lex are up to, but Lex said their work was important to prevent meteor freaks from killing others.
Dr. Bethany didn't believe him though. Clark and Chloe later visited Tobias at his house and while offering ice tea, Tobias almost dropped a glass but Clark used his super speed to catch it. He was startled when his glasses fell off, gasping and clutched his head before asking them to leave. Clark and Chloe were suspicious so he used his super hearing to listen in on Tobias calling to Dr. Bethany, reporting that he "found another one."
Clark discovered Dr. Bethany's involvement and went to confront him at the hospital but he denied even knowing another victim, Daniel Kim and maintained that Tobias' file was confidential. When he turned away, Clark distracts him by blowing on some papers with his super breath and stole Dr. Bethany's laptop.
Clark took it to Chloe but she was missing. He then visited Tobias again to question him. Clark thought Chloe was taken because she was a witness, but he was shocked when Tobias reveals that Dr. Bethany is only collecting meteor-infected people. The doctor had Chloe abducted and was experimented on strapped to a table, naked, while masked figures scan her body and took samples.
Dr. Bethany admitted to Lex that his computer was stolen, and it contained information implicating LuthorCorp. Lex instructed him to bring Tobias back and recover the laptop by any means necessary. Tobias was preparing to leave with Lana Lang when Dr. Bethany arrived, claiming that it was finally time for Tobias' surgery. Tobias seems prepared to leave with Dr. Bethany but turned off the lights in the house and retrieved one of his father's guns. Dr. Bethany announced his intention to kill Tobias and Lana with a stun gun designed to fake a heart attack to cover up his research. Lana intervened and the three had a standoff in Tobias' home.
Tobias tries to scare him away with the gun, but they struggle. Lana retrieves Tobias' gun. She shoots at Dr. Bethany at the same time he blasts Tobias with the stun gun, but Clark super-speeds into the confrontation.
