Mainframe
Mainframe is a dork. A computer dork, to be precise. (Both in that he is a computer that is a dork, and a dork about computers.) He'd rather tackle complex mathematical problems than join the inconvenient galactic conflict with the Decepticons. Despite his distaste for combat, he won't shirk his duties when called upon. If anything, he hopes that if he simply must fight, that he'll have the chance to use his considerable brainpower to end things quickly.
Alas, his partner, Push-Button, would rather convert to a piston rifle and blow stuff up than be stuck debugging Mainframe's programs. Naturally, the two don't especially get along.
