Roger's goal is to show The Critic what his world would be like if he was never born because he believes he made an impact on others. However, it turns out that if Critic never existed, his fellow reviewers would hold very successful careers, as well as Roger. When realizing that he could have been God's "number-one guy", he decides to kill the Critic in a fight. He taunts the Critic to shoot him, after God told him that angels could not be killed. Unfortunately, he is easily killed by the Critic, realizing that God made "a dick move" by lying to Roger.
Roger makes a return in the Scooby-Doo review. After his death, he is in charge of running Purgatory. He tells Critic that this is where angels go when they die, only to tell him that he's the only angel in Purgatory because he didn't know angels could be killed. He summons the Critic to warn him that a great catastrophe is approaching and his only hint of answer lies in the review. When the Critic and his past and future versions of himself finish the review, and destroy the DVD for the sake of mankind, he appears to the Critic one last time. Roger lets the Critic know that many new adventures lie ahead of him, and that he'll be watching him; making sure he has something to critique.
He later reappeared in the review of Scooby-Doo 2 four years later. He first warns the Critic that his reign of terror is not over by a long shot, and that he must complete what he started, by reviewing Scooby-Doo 2, and magically making a DVD copy of the movie appear for him. Roger then shows up in person, in the guise of a not-at-all-suspicious security guard that the Critic didn't even know worked there. He tries to convince the Critic he is behind his being forced to review the movie, but the Critic doesn't believe him. Throughout the episode, Roger slowly loses his mind, as the Critic can't seem to figure out he's behind everything, to the point where he practically begs him to frame him.
