Chromia is a soldier under the command of Elita One and seems to function as a second-in-command for her, leading the rest of the team when Elita’s not around. She’s brave, hard as nails and, not surprisingly, in a relationship with Ironhide. She has also taken over from Firestar as Flareup’s mentor when the latter turned out to be better suited to more offense-oriented tasks.

Chromia is one of the many cybertronians that were subject to Jhiaxus’ experiment of trying to introduce gender in the cybertronian race. Part of a later stage of the experiment, Chromia isn’t as mentally damaged as Arcee or Crasher.
