When I was a kid I always felt bad for
Shockwave. I mean, Megatron had an arm cannon that rested on his arm and the thing was bulky and probably got in his way but at least he had two hands. I bet poor Shockwave had a bitch of a time opening jars. Not to mention he was all alone on Cybertron, so it isn't like anyone could help him.
Not that anyone would have anyway, Decepticons were kind of dicks.
