Bob and Lisa Vorsh are a pair of villains from the anthropomorphic webcomic known as Jack, however they often seem to act as a single being due to them both sharing the role of the Sin of Gluttony.
When alive they took the form of a pair of Compsognathus, a type of chicken-sized dinosaur but in their demonic Sin form they are skeletally thin, extremely tall and now in possession of retractable claws and a blade-tipped tail. They shares this demonic form with one another, making it quite disturbing to behold (even by Sin standards).
While alive, Bob lived a rather mundane life, working an office job and seemingly never having time for fun. All this changed when Bob met his future wife and partner-in-crime, Lisa at a Christmas party. Like Bob, Lisa harbored thoughts of cannibalism and it was the meeting between the two that finally let them act out on these urges; the two cooked one of Bob's co-workers alive and then devoured her. After this, the two went on a cannibalistic killing spree lasting years.
Though the events surrounding Bob and Lisa's deaths are unknown, it is hinted at that the two killed one another. In Hell, Bob and Lisa became collectively the Sin of Gluttony. Though Bob and Lisa can eat and eat others to their heart's content in Hell, the drawback is that they are never full for long, that and everyone in Hell tastes like sulfur. This has led the two to sometimes venture back to Earth and feast upon the living.
Despite the fact they were once lovers in life, Bob and Lisa near constantly cheat on one another, in life and death.
Bob and Lisa also frequently act somewhat like minions to Dr. Kane, though Sins are not known for their loyalty towards one another.
