"Marcus Grayson was a former boxer turned OSI operative hired by Oscar Goldman to watch Steve Austin's back during a sting operation mission. Ultimately, Grayson finds himself taking part in a battle royale fight aiding Steve, though not before Steve initially mistakes him for a bad guy and delivers a bionic punch, which Grayson just shrugs off. He is played by real-life boxing star George Foreman."@en . "Marcus Grayson"@en . .
