Robbott De Negro is a ex-gangster and rap artist who is mentioned on the Lithium FM news in Grand Theft Auto 2. He was secretly admitted to hospital amid claims that his skin couldn't cope with the amount of metal piercings he had adorned his body with. De Negro had denied claims he had a piercing problem.
Robbott De Negro is apparantly a real life rap artist, as, according to the game credits, he contributed vocals to two songs on the soundtrack (Negro Vs. Conner's Showin' Me Love and E=MC Good Times' Jacking In Hilltown). His name is a play on that of actor Robert De Niro.
