On November 16, 2006, World Wrestling Entertainment announced that Marcus had signed a contract with the company through their official website. He debuted for their ECW brand under the ring name "The Alpha Male" Marquis Cor Von on January 16, 2007, in a win over Cassidy Riley. Reportedly the name change was motivated by World Wrestling Entertainment's desire to have him appear under a name they could trademark. One week later, the spelling of the first name was tweaked to Marcus. Not long after his debut, he was made a part of the forming New Breed stable, and with them feuded with the ECW Originals. After the feud died down, Cor Von took several months off for unspecified "family issues", then was released from his WWE contract on September 19, 2007 without making a return to television
