Forth Right acts as a self-righteous conspiracy theorist, passionately condemning nearly anything against his ideals and musical preference (specifically targeting West Coast hip-hop music and classical music), while promoting old school and golden age East Coast hip-hop music feverishly. Forth Right is also known to dislike thin women (clearly expressing preference towards fat ones) and enjoys sci-fi conventions.
As a result of his behavior, Forth Right is generally disliked by the station's listeners, as evident from the station callers who wish that the DJ play music instead of frequently broadcasting what amounts to soapbox rants. Radio Los Santos DJ Julio G even comments on Forth Right's mannerism during the closing of Dr. Dre & Snoop Dogg's "Fuck wit' Dre Day", claiming Forth Right is "wack" but has nothing against the choice of music played on Playback FM.
Forth Right MC is voiced by Chuck D, who was the lead rapper of Public Enemy (which has a song, "Rebel Without a Pause" on the station), as well as an author, producer, and former DJ.
