Revenge of the FallenEdit
Chromia is the blue compenent of Arcee. She and her Arcee sisters Arcee and Elita-One chased Sideways down a alley way in Shanghai. They then returned to the base. They were not seen until the Autobots were transported under a net and taken to a C-17. They then jumped out to the Egyptian town and prepared for battle. When the Decepticons arrived, her and her sisters went with Ironhide to go find Sam. When they found Sam, things began to fall apart as Arcee and Elita-One were killed and her and Ironhide were trapped by Bonecrusher,Starscream and several Protoforms, so they order Sam to flee. It is unknown if she survived the battle or died with her sisters.
