My G1 Prime has them in the same shade as his legs, with (increasing less as time goes on) silver paint.Oh yeah, no disrespect to Ditillio and Forward intended, it just suddenly struck me as interesting/odd is all and I wanted to see what people thought. Looking at TM2 Megs he doesn't seem to have any necessarily organic parts (in the same way as Optimal Optimus' gorilla chest is organically styled but doesn't seem organic per se), but then it becomes this big thing in BM.
That's sort of what I was thinking, except that G1/old-school Megs did show an aversion towards organics and BW Megs (as opposed to BM Megs, who I maintain got driven a little space-crazy by being strapped to the outside of ship during a presumably long transwarp trip) seemed not to care either way (or to put it differently was typically pragmatic about the whole thing - power is power no matter whether it's organic or mechanical), whereas both Prime and Primal show a fondness/appreciation for organics. Based on the sparks involved, you'd think if anyone was going to lose their organic side it'd be Megatron^2, not Optimus^2.
I'll sorta pay that what with the pseudo-Biblical Covenant of Primus stuff, and I can think of a few various fanwank scenarios that'd sorta work myself. I'd still like to hear Verno's take on all this though.
