"Dangerous" Dan McGrew is a player-character from the Artificial Reality game Streets of Laredo. A bare fist fighting expert, players could select Dan from a list of 3 characters, which also included Brett Riverboat and The Riviera Kid. 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. Rimmer chose Dan McGrew.
