It's not just an epic group-shot introducing the Shattered Glass Repair Crew. It's also giving us a window into their team dynamic.

Mirror!Prowl is dead-center, flanked by his fellow Evil Autobots - a position of power and focus that naturally draws the reader's eye. He's also the only one whose stance conveys a definite sense of control/authority. Mirror!Ratchet and Mirror!Bulkhead look like they're ready and waiting for the command to attack. And Mirror!Bumblebee is just...being his disturbed self. (Honestly I doubt anyone can keep him safely and reliably under control.)

Overall, I think it's pretty clear who was in charge while Mirror!Optimus was stewing as a severed helm in Emperor Sumdac's basement.

When Megatron just agrees to take in a random techno-organic and a mute Autobot:

Meanwhile, in the "Mirror Mirror" episode:

FAN DESIGN for a Shattered Glass Bulkhead. Very simple but I really like how he came out, especially because Bulkhead is one of those designs I find kinda scary to draw due to his... well, BULK.

ANYWAYS! This version of Bulkhead is in charge of all the SG!Autobots Drone Operations in his universe. So, he repairs them, puts them into squads, sets up their patrols, and even leads them into heavy combat situations. But he is actually an honor-bound warrior. He believes all of the drones under his command are individuals. In fact, he has a weekly event he holds where he has new drones reveal their chosen names and helps them give themselves their own paintjobs.
