Optimus Prime is dead. The terrifying truth is that the grief-stricken Autobots have lost their leader and greatest warrior - and Earth has lost its staunchest defender against the Decepticon menace. You'd expect the Decepticon leader, Megatron, to be celebrating now that Prime has gone. But Megatron's is not the most rational and logical of minds right now, particularly after Lord Straxus' mind-swap attempts. Far from being joyous, the Decepticon leader is utterly subdued - the spectre of Prime's all too recent presence a constant and haunting companion! Could it be that Prime will be as much a problem dead as he was when he was still alive?
