Stroman and Johnson stated that "Tribe" would have a rotating focus on its multitude of members not seen in the early (and only) issues. Trading card sets put out for the series showed a number of these potential future characters, including "Fly Girl", a New York runway model and fashion designer with flying abilities. "Fly Girl" supposedly produced a line of clothing for Tribe's headquarters, the "Beat Down Gym", and in a touch of real-life commercial synergy, Stroman and Johnson advertised similar "Tribe" fashions for sale in advertisements within the comic book. Many of the items (The Beat Down Gym - Hype Club and others) were sold by the creators at comic conventions and online.
