Prowl

Prowl is the Autobot military strategist. As such, Autobot Commander Optimus Prime keeps Prowl near at hand for his indispensable expertise. Prowl is quiet, competent, loyal, and possessed of almost endless patience.Prowl's dedication to logic and reason make him an excellent strategist, but not much of a socialite. He really doesn't tend to get along well with his fellow Autobots, many of whom find his strict adherence to military protocol stifling, and his uptight personality sure doesn't help matters. He does not react well to the unexpected, to the point that it can literally scramble his cerebral circuits.

History
Prowl is one of the Autobots that helped liberate Coruscant from the evil Sith Legion. Later he got his battle computer damage and had to link up to another one to survive.
