Busman is an idea for a comic book superhero created by Otto Mann.
Otto's idea was that the character would drive a bus by day, but by night fight vampires in a post-apocalyptic war zone. Otto later went to a comic book convention, with the intention of showing his idea to Jack Tate, but it's still unknown whether Tate liked Otto's idea or not. While traversing The Desert Busman picks up various passengers and safely takes them to Garlicville after fighting off the hordes of Mutant Vampires. He also met Busbabe while escorting the passengers.
