Judge Roy Spleen is an honorable judge of The Underworld, and is a reccuring minor supporting character in the series. Judge Roy Spleen was first seen in Keeper of the Reaper in season 6, along with, to the judge's displeasure, Fred Fredburger. He is voiced by Phil LaMarr.
Roy Spleen is a very strict and short-tempered judge who makes hostile threats or decisions towards those who misbehave in court. Despite his stern boldness, Splenn doesn't appear to be very intelligent or competent, since he at first didn't know he was the judge for the case of the Keeper of the Reaper, and Fred Fredburger managed to steal his gavel easily. He also immediately assumed out of arbitrariness that Billy and Mandy came to court for a wedding instead of a lawsuit. He neglected to take action when Billy was leading his witness Irwin to give out a forged testimony and Mandy had to point out that's not legal.
