You know the old saying 'you'd lose your head if it wasn't screwed on'? Well, it looks like the Autobot Fortress Maximus has gone and done just that - literally! The trouble is, he hasn't exactly picked the best time to do it. The Decepticon Pretender Beasts are on his trail, and when they catch up with him, they're going to terminate him! Not really the time to go to pieces, wouldn't you say? To add to his problems, Spike Witwicky, Fortress Maximus' binary-bonded partner, doesn't want anything to do with Transformers anymore!
