Roy Rothman was the main antagonist of the Season One episode "Zero" of the WB TV series Smallville. He was the brother of Amanda Rothman and sought out vengeance against Lex Luthor when she committed suicide.
He was portrayed by Eric Breker.
Roy and Amanda had a very close relationship as she was the only one to visit him when he was in prison in Central City. While Roy was in prison, Amanda went with Lex Luthor as his escort to Club Zero in Metropolis. There, she discovered that her fiancé Jude Royce was there as well, with other women. She broke it off with him, and when he tried to kill Lex for ruining their relationship, she shot him. To protect Amanda, Lex told the authorities that Max Kasich killed Royce. She was then told not to speak to Lex again, causing her to commit suicide. Learning his beloved sister died, Roy vowed vengeance and targeted Lex as the source of his sister's misery.
Plotting his revenge, Roy met a stranger who looked exactly like Jude and embarked on a plan to ruin Lex's life.
Coming to Smallville, Roy had the imposter Jude Royce stalk and harass Lex's former bodyguard Max for the truth about Amanda's death that night at Club Zero. Roy posed as a contractor working on renovating the Talon and argued with Lana Lang about the plumbing. Max tried to speak to Lex about Jude Royce but Lex wanted no part of it as it was in the past. Not getting the answers he wanted, Roy killed Max and cut off his hand and placed it in a gift box to intimidate him. Clark, Lana and Lex arrived at the Talon, to meet the contractor (Roy) but they find him on the floor unconscious. They rouse him and he reports that someone knocked him over the head. They see the box on the table with Lex's name on it and inside was Max Kasich's hand. Next he had Jude Royce poison Jonathan Kent's herd with chemicals stolen from LuthorCorp. Finally, Roy had the imposter abduct Lex and tortured him at the former site of Club Zero.
At Club Zero, Jude is once again about to shoot Lex when Roy Rothman shoots Jude. Roy turns on the lights and music and shoots the chains holding Lex upside down. Lex crashes to the floor and recognizes Roy as the contractor from the Talon, but he's actually Amanda's brother from Central City. Roy then revealed his entire plan that about a week after his sister's funeral, he walked into a restaurant in Blüdhaven and met a short order cook who looked exactly like Jude Royce. Lex agreed to tell Roy the truth about what happened the night Jude was killed and says it was Amanda who shot her fiancé.
This is not the story that Roy wanted to hear and he becomes furious. He picks up Lex and puts him up against a huge fish tank. Just as he pulls the trigger, Lex twists away and jumps back over a railing. Clark walks in just then. He uses his super speed to push a couch under Lex, then runs upstairs and throws Roy against a post, rendering him unconscious. Then he runs back to the door and pretends to have just arrived.
