The Transformers: Robots in Disguise Vol. 4
Megatron's back... and CYBERTRON will never be the same. Everything BUMBLEBEE and his AUTOBOTS have built teeters at the edge of collapse-and STARSCREAM has to make the choice his whole life has been leading to. And meet the new PROWL-deadlier than ever, colder then any other AUTOBOT, and ready to end the DECEPTICON threat.
