Flonominal, real name Derrick Cornish (voiced by Busta Rhymes), is a rapper, and member of Thugnificent's Lethal Interjection Crew. His vocabulary seems to be quite limited, and uses hip-hop slang frequently at the end of, even in between his sentences, and if he can't think of anything else to say such as "Word!" and "Nah mean?" and also adding "son" in his sentences, hinting that Flonominal comes from New York City (like his voice actor). Although he puts on a hard-man, gangsta facade and is as loud as Thugnificent at times, he is shown to be soft and sensitive, as seen as when his mother called him and scolded him about the controversy caused the Lethal Interjection label and the constant attacks on the elderly by Thugnificent's rivalry with Robert Freeman (Granddad), and when Butch Magnus Milosevic viciously hit him on the leg with a baseball bat, after demanding Riley's chain back. He resigns from the Lethal Interjection in "Bitches to Rags" when Thugnificent is unable to pay for the house and when Thugnificent gets him fired from a job as an office worker. In this episode, however, he is not voiced by Busta Rhymes.
