I dont think to scale human figures could be justified as standalone figure sets, they would jut be too small, but hey should be packaged along with the Transformers. Yes even if they were the same as the movie battle scene figures. I'd prefer something more posable even if it was just a bendy posable type figure which animated aesthetics would suit.
Bumblebee should have been done at a basic size and come with Sari at a deluxe price point. Elite Guard BB could have come with another figure. Prowl could have come with Fanzone instead of the traffic light. Supreme Bulkhead already comes with the Headmaster though I dont think the head transforms or does anything which is a shame.
I think human figures would suit Animated more than any previous series. I envisage them something like the Playmates Simpsons figures. Or if they were done in scale, they could be done in single or twin packs at the £1.99-£2.99 mark; there could also be "deluxe" non-Transformers at around £4.99, such as the "Pretenders" or Fanzone in his car.
I'd only wish for human characters made into toys for a particular TF series if they could interact in some way with the robots themselves. Maybe something along the lines of Masterforce or the old pre-Diaclone pilot idea would be nice. If they do nothing the human toys wouldn't be too interesting. All they'd do is just stand by the side of the TF on your bookshelf looking like a spare prick.
