We decided to give Roborexus an updated design since his first appearance
back in issue 1. He was originally a throwaway reference/homage to the transformer Grimlock, but since we’ve decided to feature the little robo-dino a bit more prominently, we simplified his design to make him easier to draw and not such an obvious riff off of Grimlock.
But we don’t plan to go back and alter the design in his original appearance. We’ll just say that was a prototype build.
There won't be a page posted next weekend (Labor Day weekend here in the US), but the comic will return with a new page on Saturday, September 8th. And it'll be one of my favorite pages of this issue so far.
