Spare a thought for poor Optimus Prime. He's survived the combined attack of Megatron and the Predacons, survived a painful teleportation to his homeworld of Cybertron, and now faces death once more...this time at the hands of his fellow Autobots! Thanks to a skilful bit of manoeuvering, Megatron's got the Cybertron Autobots convinced that Optimus Prime is a Decepticon imposter!
