They are getting bits and pieces of data so far. Probably that is how they managed to mind scramble Arcee; from the data they collected on Breakdown. But do you think in a later episode they will get the chance to fully take apart a Cybertronian? For that would be the windfall that they are looking forward to so far. The candidates are... A chopped up Terrorcon. Although it is unlikely that new zombie bots will be produced, there is that graveyard where Megatron demonstrated that Dark Energon to Optimus. Plus it is pre-disassembled and easier to transport. Vehicon grunt. Nameless and a quite frankly expendable but no less Cybertronian. Airachnid. Should her end come about, it should involve "weak fleshbags" decapitating her. A fate fitting for someone that seeks to collect the heads of humans before exterminating them from Earth.
