Canon

The closest thing to an official explanation would be the scripted episode Dark Glass written by Larry DiTillio... but of course, this episode was never produced, but then again, existing canon doesn't necessarily conflict with it either... so I guess you could take it as pseudocanonical evidence. <shrug>

If Starscream's ghost could possess Waspinator et al, there's no reason why Dinobot's own ghost/spark/soul etc. couldn't have possessed Dinobot II once Rampage's had left the building.

Possessing a body just to die again?! Who does that?! :p ;)

Blood-dee hell, I can't find Frenzy & Rumble anywhere at my local stores! I had a search online today, and the only place I could find them was at Robot Kingdom, who have now jacked their price for that set up to US$59.90! :eek:

Does anyone know if Hasbro Australia has any plans on releasing these toys here??? Maybe I should give Hasbro AU a call... (>_>)
