Chromia is tough as nails, and always spoiling for a fight. She's been friends with Ironhide for centuries, and their reunion on Earth was one of the high points of the war for both of them. Now, they work side-by-side, hunting and destroying Decepticons. Neither of them has ever been happier. The two robots make great partners, and she, along with her sisters, is an invaluable part of the team.
