It's a shame really, because Mainframe's Tech Spec bio paints a very interesting picture of a 'bot who really just wants to be left alone to process data and write code. Pretty much the Transformers version of Moss from the IT crowd, then. Let's put it this way; if ever he gets a voice in a cartoon, Richard Ayoade should be playing him. It's certainly his voice I'll hear when I see Mainframe's dialogue in comics. Also, notice the Mainframe's intelligence and skill levels; perfect 10. This guy is formidable, yo.
Mainframe then, was one of the better Action Masters, a good toy, and a good, well thought out Tech Spec bio. Here's hoping that Rocherts do something pretty darn cool with him on the Lost Light (unless they've killed him already). Also, what do you think he might have transformed into prior to Actionisation?
