Arcee has dedicated her life to the power of information.  As a teacher, she saw to it that young Autobots all learned the value of the facts, and how to tell truth from lies.  During the war, she turned her dedication to the truth to carrying data for the Autobot High Command, often from deep behind enemy lines.  She will face any danger to defend what is right, no matter what the cost.
