Herman Stevens Jr. is an American attorney and former professional wrestling manager, best known for his attorney gimmicks as Clarence Mason in WWE and as J. Biggs in World Championship Wrestling (WCW) from 1999–2000. Stevens entered WWE in 1995 as Clarence Mason, a lawyer primarily introduced to play off the publicity lawyers had gotten during the ongoing O. J. Simpson trial. His character and speaking style were based on Johnnie Cochran. According to Jim Cornette, Stevens' stage name was a play on Clarence Darrow and Perry Mason.

Clarence Mason was introduced as the legal counsel for Jim Cornette, who was attempting to reverse a decision at an In Your House #3 pay per view event that had seen Yokozuna and the British Bulldog, whom Cornette was managing, lose the WWE Tag Team Championship held by Diesel and Shawn Michaels. Following this, Mason continued his association with Cornette and his stable of wrestlers.

In August 1996, Mason left the Cornette stable and managed Crush (Brian Adams). Adams had been arrested in March 1995 and spent some time in jail; upon his return WWE gave him a biker gimmick and used his real-life incarceration as part of a storyline, with Mason as his attorney. Later that year Mason became manager of Faarooq and the two formed The Nation of Domination, a heel stable loosely based on the Nation of Islam and Black Panther Party, Mason still managed Owen & The Bulldog while with The Nation, but got fired by the Bulldog in March 1997, In mid-1997, Faarooq "fired" Mason from the Nation of Domination (according to Mason in a shoot interview, he requested to be taken out of the Nation because he was uncomfortable with their racial comments in storylines and interviews that they were doing), and Mason was written off television and released from his WWE contract.

Stevens resurfaced in WCW as J. Biggs, where he managed Chris Kanyon. A few months later, Kanyon dropped his association with Biggs, which left him to search for a new client. This time, Biggs picked the newly established tag team of Harlem Heat 2000, which consisted of Stevie Ray and Big T. The team feuded with Booker T. Biggs gained a (kayfabe) court order against Booker T, which stated he could not use the letter "T" after defeating Booker at SuperBrawl 2000 when the lights were turned off and Big T rolled Booker up when they were turned back on as per match stipulation. Shortly thereafter, Biggs was released from his contract and left the wrestling business.
