Official Hasbro Photos of: Protectobots Spoiler: Protectobots Defensor Spoiler: Defensor Constructicons Spoiler: Constructicons Cyclonus Spoiler: Cyclonus Ultra Magnus Spoiler: Ultra Magnus Reportedly according to a Hasbro rep at Toyfair, it indeed was a scale issue. Of course both Bonecrusher and Scrapper also have more updated vehicle modes. It's not just that noticeable for them. You are absolutely right. The Legends figures are all glorified chest plates or weapons. They needed to get rid of Groove for Rook mostly to spread the costs of a Brawl mode. I think Rook is a genius move to reflect how policing has change from that of the 80s (in the g1 cartoon) to the more militarized form you have now. Same Streetwise having a shotgun.
