"Before the Great War, Teaching Unit RC-687-040—Arcee for short—was a teacher, giving young Autobots the knowledge to make their own decisions and spurring them to think for themselves. Once the conflict erupted, she became an intelligence officer for the Autobot war effort, serving under Highbrow in such risky endeavors as Project Omega."

A suggestion the team had for Arcee is having her sound like the slug lady from monsters inc. A lot of freedom for interpretation here as Arcee has gone through a bunch of different interpretations over the years.
