Chromia is an Autobot. Her sisters are: Arcee and Flareup. She transforms into a lavender-dark blue Suziki B-King 2008. In Revenge of the Fallen, Chromia and her sisters chase Sideways down an alley in Shanghai. Later in Egypt, the sisters are sent with Ironhide as an advance team to recover Sam. The pink and purple sisters are then hit by what seems to be a clone of Bonecrusher, but Chromia is seen taking cover. It is said that they survived.
