He's about as big as any other AoE Deluxe. The legs carry no vehicle kibble, making the toy bulkier above the belt than below. It's typical of the standard of engineering that we've seen in AoE due to the screen models being so counter-intuitive to toy designs by having robot modes with minimal alt mode parts. IMHO Lockdown does a better job than some other toys in its redistribution of vehicle kibble in robot mode. I do like the way that the 'backpack' parts compacts itself to try and minimise its appearance; it achieves this with greater success than say either of the Leader Class Optimus Primes or Voyager Galvatron (although admittedly a Lamborghini Aventador isn't a big blocky vehicle like a Western Star or Freightliner truck, so there's relatively less kibble to compact/redistribute). I can see that HasTak designers have done a rather commendable job with the screen model that they were given to translate into an action figure. I just hope that the screen designs for TF5 will go back to being more translatable as toys.
