Wheeljack was Cybertron's most dangerous mad scientist. Braninstorm was,,, a scientist who created WMDs possibly too dangerous to actually use. Wheeljack was often a liability to himself. Brainstorm seemed to be onconcerned with ethics. Wheeljack served directly under Optimus Prime, but Brainstorm might actually be the better inventor. So did Optimus choose Wheeljack because of Brainstorm's moral ambivalence? Just trying to figure how these two characters would relate as they are both "the fixer" guys who have never directly been compared and contrasted.
