"Following our defeat at the hands of the Autobots, Lord Megatron found himself in the crosshairs of usurpers across the galaxy. Two-byte traitors and turncoats who thought they had what it took to command the Decepticons better than Megatron. To this end, I was instructed to eliminate these threats (minimal as they were) by any means necessary. Rather than dirty my own servos, I chose to reconstruct a damaged Autobot; One who had been a particular thorn in Megatron's side. Impactor. Just processing that name makes me ill. Though he doesn't know it, Impactor's new 910-1994 body type is wired to seek out high priority targets and eliminate them with great prejudice." -Excerpt from personal datalogs of Decepticon spy Shockwave Halfway through sketching this bad boy up, AA2 came out, and gave us an actual factual TFA Impactor. Luckily I could salvage my idea with just a few tweaks.
The head kind of reminds me of Judge Dredd. I'm not sure if that's what you were going for, though. Still, excellent work.
