Richter Maddox was a director at Belle Reve Sanitarium but ran an underground fight club between super-powered patients from his hospital in the WB/CW TV series Smallville.
He served as the secondary antagonist in the Season 6 episode "Combat".
Maddox secretly ran Live or Die!, an underground fight club that pitted metahumans against each other in brutal death matches. The fights were broadcast on the internet for an extremely high fee and fans could choose who wins and who dies. Maddox encountered the Phantom Zone escapee Titan in a bar in Oklahoma.
Titan was immeasurably strong and always seeking new opponents to fight, and soon Maddox made the murderous alien the main attraction for his fight club. Through Oliver, Clark got word of an underground fight circuit being broadcast over the internet. He and Chloe watched on the computer as the main fighter, Titan, battles a man who can project energy from his hand.
After Titan killed the metahuman, Chloe couldn't track the signal or get past the security and started to investigate. However, Lois Lane, desperate for a story for the Inquisitor, discovered Chloe's leads on the fight club and decided to look into it. Lois went to the abandoned Air Force hangar and encountered one of the club's security guards, Athena. After seeing Lois and Athena spar, Maddox pulled a gun on her having been impressed and put Lois in the next battle.
Chloe uncovered his identity as the director of Belle Reve while Clark discovered that Titan was not a metahuman, but a Phantom Zone prisoner, and sought out Maddox's club in order to defeat him. Clark broke into Belle Reve and confronts Maddox as he leaves for the night. Clark demanded a fight and demonstrates his powers to Maddox to convince him catching a bullet with his bare hand. Maddox agreed to let him fight and took him to the hangar, where Clark's first opponent was Lois.
They're forced to pretend to fight and Clark used his heat vision to destroy the equipment. However, Titan's target was indeed Clark and he interrupted Clark and Lois' fight to take Clark on. Clark uses his heat vision to destroy the visual equipment. Titan spotted him and went to confront Clark. Maddox was upset that Titan was ruining his show and tried to stop him. Titan responded by throwing Maddox across the arena, killing him instantly.
