"Stormbringer" debuted in July 2006 and is set during the same time frame as "Infiltration" as in the first issue, Optimus Prime receives Ironhide's message from "Infiltration". The setting is far from Earth, and the Transformers are scattered across the universe since Cybertron had been made uninhabitable by war. The series' main villain is Thunderwing, and key protagonists include Jetfire and the Technobots. The mini-series was promoted with the tagline "No Humans on Cybertron!", referring to many fans' discontent over the human cast of "Infiltration". The four-issue series was written by Simon Furman and drawn by Don Figueroa. The two had previously collaborated on several projects for Dreamwave, as well as IDW's own "Beast Wars: The Gathering".
