Which robot that has a screen for a face is your favourite? (The ones we've had are all Cons, it's so unfair to the Bots...) Anyway, my favourite is Prime Soundwave. The series had a lot of fun with him, putting all sorts of things on his monitor: a heartbeat, a radar map, a photograph, a diagram and even a smiley face . It was a clever and witty thing to do, and it made a good compensation for him not speaking a lot. Sideways didn't do much with his face. And Lockdown, well he looks great, but I don't think he will be using his monitor face a lot. Soundwave gets my vote.
