D-Bear was created by John Layman and Rob Guillory. His first appearance was in Image's Chew #1.
Tracy is a cannibal sous-chef at the Fairmount Speedy Upholstery. He had murdered and ate several victims before he made the chicken soup that was tasted by Tony Chu. Chu's special gift, cibopathy, made him relive the most recent murders. Confronting Cobb with his discovery, Cobb slashed his own throat, rather than to go back to jail. Wanting the names of Cobb's other victims, Chu bit off parts of Cobb's face to again trigger his special gift.
