Brett Riverboat is a player-character from the artificial reality game Streets of Laredo. A knifethrower, players could select Brett from a list of 3 characters, which also included The Riviera Kid and "Dangerous" Dan McGrew. When the Armageddon Virus attacked Starbug's Navicomp and Kryten's mind, the rest of the crew were able to project themselves into Kryten's western-style dreamscape. They each took on the skills and costume of a different gaming character. After the other characters were chosen, Lister was left with Brett Riverboat.
