Following on from the 'Worst Button Sounds' thread, what are everyone's favourite sound effects or general electronics on a TF? The stand-out one for me has to be Animated Leader Bulkhead. I like the voice clips, and the changes to the electronics (light colour and voice) when you pop the Headmaster on are the icing on the cake. I also like RiD Optimus Prime's effects, bar the 'wrong continuity!' "Optimus Prime, maximise!" phrase. Any others?
