OKay, we back in the Defender comic story, Defender had three friends damaged by his evil clone. One was very roadbuster-looking, named Revolver... In the Assaulter comic they recover Revolver and friends for repair: The assaulter toy ships with a set of mini-vehicles, including one that's sorta Roadbuster-like. (second guy in the second row). Looks like he'll be rebuilt as a Core technology? Would you be interested in a Heartmaster not-Roadbuster in 2013?
