So much discussion about the difference in designs between Transformers to TLK and then Bumbleebee. Yes, there are subtle differences but there are subtle differences between the first 5 Transformers as well. None of the designs would look out of place in the other. Brawn would have fit in just fine in Transformers while Barricade would have been just fine in Bumblebee. The only real aesthetic change IMO was having more of their internal structures covered with armor in Bumblebee.
