Why are so few Generation 2 toys actually featured?
Furman, with the acclaim from his original run on the US book, was basically given total creative freedom by Hasbro. The only change likely to be forced was Megatron’s new body, which allowed a greater narrative freedom, and also revamped the character after his less than impressive earlier incarnation. Aside from this, it seems Furman was largely left to feature who he wants, and most of the Generation 2 characters featured fulfil plot purposes [e.g. Rotorforce and the Laser-Rods are tangible results of Bludgeon’s mission].
