Would really like for a scene of Ratchet taking few shots at Shockwave before he retreats. But that wouldn't be the reason for Shockwave to retreat. Fans are smart to know Shockwave doesn't retreat to few rounds of gun shots from one Cybertronian.
He looks different in each scene, sometimes he's barely shorter than Optimus, sometimes he's almost as tall as Bumblebee. Compare 0:55 and 3:55, this is weird since as far as I noticed Optimus is two times taller than Bumblebee
I actually like the green why more than the yellow, it makes him more vibrant when he stands with the other autobots. DOTM-AOE Ratchet will always be my preferred version of Ratchet.
