I found the botcon Overlord/Gigatron interesting but the head always looked wrong to me, not fitting the mold. Anyway, this is a GDO Megatron repainted and with TFP Dreadwing's head.
It looks great, yes, but it lacks the full, childbearing lips of IDW Overlord that purportedly don't move when he speaks. 8/10 (the lips are worth at least 5 points in my book, but I'm feeling generous today)
It's Prime Overlord, though. Prime characters don't have lips at all. Or noses, for that matter. On-topic, that is really stellar. Good job.
