The Transformers: Stormbringer is a comic book mini-series, published by IDW Publishing. The series debuted in July, 2006 and is set during the same time frame as The Transformers: Infiltration (the first issue shows Optimus Prime receiving Ironhide's call from Infiltration). It technically consists of issues seven through ten of the ongoing Transformers saga, which is split into arcs instead of being one complete series. The four-issue series was written by Simon Furman with art by Don Figueroa. Unlike Infiltration, the series is set almost entirely on Cybertron. The series is available in The Transformers: Volume 2.
