Walt Masterson is a jewel thief.
Season Three[]
Walt used his apprentice, Nathan Dean, a metahuman with the ability to project a supersonic sound, to distract the people at the Smallville Jewelry Store with his high-pitched shriek while he stole the jewels. Clark was able to stop him and Nathan but was blinded in the process of stopping Nathan's super loud scream. Masterson had Nathan kidnap Pete Ross to get Judge Abigail Ross to dismiss the charges against him. However, Clark managed to save Pete and defeat Nathan, and Masterson remained in custody.
