For millions of years, Chromia serves as one of the crack troops of the Autobot underground on Cybertron. While tough and determined, Chromia retains a wity sense of humor. She believes that words are fairly meaningless without action to back the up. It is a philosophy she employs in and out of combat. Her blunt honesty often puts off other Autobots, but those who truly understand her know that this is her way of honoring the Autobot ideal of truth. Chromia is extremely protective of Flareup, whom she has agreed to watch after, our of respect for her comrade, Firestar.
