The show's first two episodes were written by executive producer Peter Hume. In this version of the series, Flash's actual name is "Steven Gordon", with "Flash" being a nickname.

The new series, based on the comic strip of the same name and its adaptations, adds a character called Baylin (Karen Cliche), a bounty hunter from the planet Mongo. She finds herself trapped on Earth and becomes a comrade of Flash (Eric Johnson), his former girlfriend, Dale Arden (Gina Holden) and scientist Dr. Hans Zarkov (Jody Racicot), who are able to travel back and forth through a "portal between the two worlds" instead of space ships. In a more subtle change, Ming will not be called "The Merciless" and will exhibit the traits of modern, media-savvy dictators.
