Jed McNally was a Smallville resident who owned a large farm near the Kent Farm in the WB/CW TV series Smallville. He served as the main antagonist in the Season Six episode "Subterranean".
He was portrayed by John Novak who played The Djinn in the Wishmaster horror movie series, Zeus in Supernatural, Faust in the English version of Adieu Galaxy Express 999, Jack Kirby in L.A.P.D.: To Protect and to Serve and Caligo in Barbie: The Pearl Princess.
Jed McNally was a family friend to the Kents and was always kind to Clark.
During the second meteor shower, McNally was buried down in the ground for three days. Exposed to large quantities of raw Kryptonite which mutated his genetic makeup, McNally gained the ability to dig underground incredibly quickly. After emerging from underground, Jed was recruited into Lex Luthor's 33.1 project before being released. Returning to his farm, McNally began smuggling illegal immigrants to work on his farm. A boy named Javier Ramirez had been brought to his farm and wanted to escape the harsh conditions with his friend Francisco. Francisco warned him that everybody who had tried to escape had disappeared without traces. When a migrant worker collapsed, Jed appeared and tells everyone to get back to work. That night while attempting to escape through the corn field, they heard a rumbling. Javier succeeded in escaping, but Francisco was drawn into the earth by McNally using his tunneling powers to trap him underground.
Javier escaped and made his way to the Kent Farm where he met Clark who invited him inside to get cleaned up and fed. In the house, Javier said he ran away from Jed McNally's farm because no one was allowed to leave and there was little food. He also told Clark about the missing people and that he was an illegal immigrant begging him not to call the police. Clark volunteered to help find his friend leaving him at the house while he went to the McNally Farm under the pretense of asking to borrow a tractor part. Jed was friendly and optimistic and talked about how the second meteor shower was actually a blessing for his farm. As he went to get the part, Clark asked the workers about Francisco and one of them mutters a phrase in Spanish that Clark didn't understand. When Clark left, Jed looked suspicious.
Later Clark met two other works from the McNally Farm who report that the ground "swallowed" Francisco. Clark used his X-ray vision on the field and saw multiple skeletons under the surface. Clark called the authorities on Jed and crime scene investigators were excavating multiple bodies. When Javier escaped custody, McNally vowed revenge against Clark and Javier and before he was arrested, he disappears into the ground. Lex was angry that Dr. Bauer did not disclose that McNally was killing his workers, but Bauer claimed he only knew that he was able to displace minerals and burrow through the earth. Lex was upset that his "test subject" will end up in jail and told Bauer he better find McNally before the police.
Clark and Javier were on their way back to meet his mother, when Javier asks Clark to tell him what happened to Francisco.
