Our original idea was to revive the Blackhawks in the future, but DC decided we should make it a new group entirely... so we (perhaps both of us, maybe just Gerry, maybe even just I) came up with the name "Sun Devils."

Additional cast members included Anomie Zitar, an apparent feline-human hybrid (fittingly, the team's resident "sex kitten"); a smuggler-pilot named Scyla, a tall, powerful woman whose personality borrowed heavily from Han Solo and who was identified as being from a colony on an asteroid belt; three clones, genetically raised as starship repairmen, who had no name and were referred to only as "One", "Two" and "Three" (at the start of the series, they spoke in unison or finished one another's sentences, but as the book moved along they started to develop independent personalities; toward the end, Two and Scyla became drinking buddies and possibly more); and Shikon, a member of the Sauroid race.

At the end of the first story arc, the team was joined by a ghostly figure called Myste, a woman who had apparently "died" while serving the Sauroids, but had in fact remained somehow alive, obtained powers and turned against them, attaching herself to the Sun Devils and giving them information and direction for the rest of the story.

At the end of the series, each act's covers could be stacked on top of one another, so that an even larger central image was created by putting the books three wide and four tall.

In a March 2008 interview, Booster Gold co-writer Jeff Katz responded to a question about the Sun Devils' role in his series by telling Comic Related that Rik Sunn is a secret member of the Time Stealers, a team of supervillains currently known to be composed of Despero, Per Degaton, Supernova and the Ultra-Humanite.
