Janson is featured as a major character in Michael A. Stackpole's X-Wing comic book series as alternately Wedge and Hobbie's wingman and an integral member of the squadron. Aaron Allston included the character in his installments in the "X-wing" novel series which followed from the comics, although Janson in those novels is prominent as a member of Wraith Squadron, not Rogue Squadron. Janson also fought against the Yuuzhan Vong during the "New Jedi Order" series of novels, and kept an eye on Han Solo after the death of Chewbacca. He was known as a skilled pilot and an expert shot, and personality-wise is known to be a joker. In his early days as part of the Rebel Alliance was mainly a gunner in the two seated version of the Y-wing because of his shooting ability. His first combat kill was New Republic pilot Kell Tainer's father during a botched mission where Doran was about to stray into an Imperial radar scan. Despite repeated attempts to get him to change course, Janson was forced to shoot him down to save the rest of the squadron. In the Wraith Squadron Series he was the first to implement the saying "Yub Yub Commander." as a joke to Wedge after fooling him during the pilot interviews. The rest of the squadron soon followed and Wedge was hounded by it for many years to come.
