"Transformers: Dark Cybertron # 1" (IDW) cover by Rob Liefeld (self-homage to "The New Mutants #87" cover). It’s a Virginia Comicon Convention Exclusive.
I usually don’t like Liefeld work, but the cover is cool!
What you don’t see here is Optimus and everyone else standing behind some conveniently placed rocks so he didn’t have to...
Thank Primus G1 robots don’t have the same anatomy as humans.
