Smokescreen is a man of action - he prefers to cut to the chase in any situation. What you see is what you get with Smokescreen - if he likes you, you know it, and if he doesn't, your dead before it matters. Smokescreen has no interest in the back-stabbing politicking of many of the other Autobots - he's just here to kill Decepticons and go home. From the size of his kill list, he's pretty good at it.
