Chuck's Reviews Transformers Titans Return and Legends Hardhead
 

Hardhead was one of the original Headmasters introduced during the Rebirth miniseries. I've always felt a closer connection to the US fiction than the Takara version, where the smaller robots were the characters who combined with transforming vehicles. Takara as usual has enhanced the experience with a cartoon accurate deco and face, while including a repainted Titan Master vehicle to round out the pack. The Legends set is the better value but may be harder to find at this point.
