Here's the plot, somewhere in the ocean off the shores of Japan, the Seacon's detect a high source of energy capable of powering their latest invention Trypticon. Turns out, the rock is actually the big lizard in his sleep mode (all curled up). Drawing energon from him awakens Godzilla and he destroys the 'cons underwater base the "Victory" He goes on a rampage until Trypticons goes online.
Well, let's have Trypticon get b*tched slapped by Godzilla and the decepticons turned into creamed jelly. Metroplex and Fortmax try to tag wrestle him but still get their fenders dented. Then Optimus uses the Matrix to communicate with the beast.............which "removes" it's madness ala "The Return of Optimus Prime"
