Has anyone read them besides me? I like them, but I don’t understand them. How is it possible for Transformers to be in the same world as Gobots? Catalyism or not, it doesn’t really make how a bunch of sentient robots to mix with cyborgs. Two different types of things. I hope I am not giving out spoiler but how did a well know transformer get made from the parts of Leader- one and Cy-Kill? The robots parts, yes but the brain parts, yuck?
