Raymond "Ray" Sacks is an antagonist appearing in the CW television series Smallville Season 9 episodes "Idol" and "Charade".
He was the corrupt former District Attorney of Metropolis and an agent of Checkmate code named Black Knight.
In the Season 9 episode "Idol", Sacks hated the actions of a vigilante known as The Blur. Ray Sacks spoke to the press, blaming The Blur for the recent happenings in Metropolis. Sacks issued a press conference demanding that The Blur reveal himself after undercover cops were accidentally captured by the Wonder Twins and when the Wonder Twins mistakenly shut down all the power in Metropolis.
When the power did return, he issued a press conference demanding the Blur to revealed himself and show he truly is a vigilante.
Before Clark Kent could step forward to confess his secret, Lois interrupted Sack's speech by telling the public how the Blur's needs to stay confident in knowing who he truly is and the best way for him to help the good people of Metropolis is for his secret identity to remain secret.
Feeling outraged, Sacks placed a trap for Lois by making her believe The Blur had sent her a rose to meet her on the rooftop of the Daily Planet. Lois believed the city would never believe Sacks, yet Sacks quickly said that The Blur would be at fault after spray-painting the rooftop with The Blur's symbol. He had his henchmen grab Lois and threw her over the roof.
Sack thought Lois died but she had grabbed onto a flagpole of the building. Clark was able to rescue her with help from the Wonder Twins who also prevented Sacks from escaping as Janya turned into a dog. Lois then told Clark how Sacks was arrested for his dirty political antics.
In the episode "Charade", Sack was released from prison which got the Daily Planet interested in checking it out. Sack offered two million dollars for anyone who could get him a picture of the Blue, as he still held a grudge against him. Lois confronted Sack outside his favorite pizza joint and threatened to have him jailed for trying to kill he. Sack tried to kill her until the Blur saved her. While holding a welcome home party at Maxwell's, a photographer arrived with a picture of the Blur.
Before Sacks could take a look at the picture, Lois staged a fake fight while Clark secretly destroyed the picture. Sack was working with Maxwell Lord to eliminate the Blur. Sacks was given the Black Knight chess piece as token of his initiation into the government agency Checkmate and while examining it, he was knocked out by Clark Kent, who crushed the chess piece. His fate after that is unknown, however he is assumed to have died.
