In the Transformers DOTM novel, the driller was an individual character, but the movie, he was refered as Shockwave. Why is that? In the novel, Optimus talked about how the Driller was a mining robot that Transformers used. But in the movie, all Optimus said was Shockwave, and said nothing about the Driller. Maybe, it's to make Shockwave look stronger. But to me, I felt like the Driller was not part of Shockwave at all. What do you all think?
