Mr. Lyon was a patron of the Windgate Club, a gentleman's club in Metropolis. Lyon frequently doted attention on one particular stripper at the strip club Windgate, who would then disappear shortly afterward. He became infatuated with a dancer named Melissa Paige but she grew uncomfortable with him and attempted to escape.
She tried to tell her story to the Daily Planet was ran over by a car and killed. Chloe Sullivan and Lois Lane received the call and witnessed Melissa's death. They both believed that Melissa was more than just a stripper and Chloe she was from the Windgate Club.

She noticed an embarrassed Clark Kent who was doing his own investigation into Senator Jennings. After Lois gave him a lap dance, Clark noticed a European man, Mr. Lyon, meeting with the owner and used his super-hearing to overhear them talking about $500,000 and the owner's "girls."
When he saw Lois Lane on stage performing a sexy dance while she was undercover, he believed she was a new stripper at the club, after asking who she is from the bouncer, and successfully bought her. During a police raid on the club, Lyon managed to get Lois out. Chloe concerned for Lois began questioning dancers about Lyon who told her that he wines and dines them then they vanish. A shocked Chloe learned Mr. Lyon had Lois. Deciding to make her his next victim, Lyon took Lois to his apartment.
He gave her a red dress to wear, which was identical to the one Melissa was wearing the night when she was killed and promised her he wouldn't peek on her changing. He asked her if she needed help putting it on after she was looking through his belongings and then she quickly puts it on.
He then takes a photo of her in the dress and tells her she's prettier in the dress then all the other dancers and she'll make them all very jealous. When Lois tries to get out, he grabs her and forces her to stay. She tries to fight back, but the bodyguard tasers her unconscious. His guard then carried her into Lyon's helicopter and tried to fly her out of the country to keep her for himself like his previous victims.
