Jason Teague was a student at Central Kansas A&M and former assistant football coach at Smallville Crows football team. Jason was even the ex-boyfriend of Lana Lang and the son of Genevieve Teague, a member of a group known as the Veritas.
Jason had dirty blond hair and green eyes. Jason started to wear the traditional clothing of football coaches and be seen wearing a red shirt, jacket, and anything with the same color.
Jason grew up in a rich society with his parents and always wanted to leave his parents' shadow. Jason decided to play football instead of studying law like his father Edward wanted and moved to Smallville to be with Lana which his mother didn't approve of. Jason wanted to be independent and live his own life with Lana. Jason even had a sense of humor such as joking in serious situations which would annoy Lana. Jason also seemed jealous whenever Clark Kent entered the middle of his relationship with Lana. Interestingly enough, even though he wanted to get away from the Teagues, he still had family sense of loyalty and even pointed out how betrayal ran in the Luthor bloodline. Jason helped his mother Genevieve search for the power stones by helping her murder Bridgette Crosby and kidnapping the Luthors. Jason even treated Lex horribly which was sinister and Genevieve kept motivating him to use his sinister personality by using the idea of Clark and Lana being together.
Jason had a loving relationship throughout their time in Smallville with Lana Lang after the pair met in Paris, France. Jason became Smallville High's school assistant football coach and was fired when Lex Luthor revealed to Principal Kwan his relationship with Lana. Jason helped his mother Genevieve Teague to locate the three Kryptonian stones that when united form a single crystal that would create Clark Kent's Fortress of Solitude. Jason and Genevieve kidnapped Lex and Lionel Luthor to discover the location of the stones and Lionel claimed that Lana had one of them. Genevieve confronted Lana and the two men started to fight until Genevieve got murdered by Margaret Isobel Thoreaux's hand through Lana.
Lex and Lionel managed to get loose and tried to escape. Jason chased the two of them into the woods, however Lex trapped him on a cliff over a river and just as Jason was about to reveal Clark's secret to him, he fell off the cliff after getting shot by Lionel.
Jason headed to the Kent Farm since he believed Clark had the secret of the stones and help Clark's foster parents hostage. A meteor shower crashed through the Kent House directly above where he was standing which killed him.
