Transformers Combiner Wars Stop Motion Series Part 2

While I still do not have a Complete Stunticons team, I was able to make due with what I had. It played perfectly into the script in my opinion. PLOT: Motormaster arrives seeking his Stunticon team, only to find 3 of its members unaccounted for, much like the Arialbots, who are also missing a member of their team. Megatron believes Optimus Prime is to blame, and Optimus Prime believes Megatron is to blame. Is there a larger force who is responsible for the kidnappings?
