I love the Transformers Kre-O line specifically for the animated shorts Hasbro created to market 'em. If you haven't seen any before, they mostly involve the adorable Decepticons committing mild acts of evil - such as, say, stealing a bit of Energon - and then the Autobots being total dicks to them. In no video is this more evident than in this one (an io9 exclusive!) in which Megatron reveals his nefarious plan for the Energon he stole. I don't want to spoil it, but it involves Megatron wearing a bib that reads "I HEART GRILLED CHEESE." 'Nuff said.
