In Greek mythology, Chromia (/ˈkroʊmiə/; Χρωμία) is the daughter of Itonus (Ἴτωνος), son of Amphictyon, himself son of Deucalion. She was also, in some traditions, the mother of Aetolus, Paeon, Epeius and Eurycyda by Endymion.
Chromia is the name used by several fictional characters in the Transformers franchise. She was one of the female Autobots, and girlfriend to Ironhide. The original Chromia was a character in the 1986 The Transformers animated television series, voiced by Linda Gary. Although introduced in the 1980s this character wouldn't get a toy until a convention exclusive in 2005. A second character named Chromia was introduced in Transformers: Cybertron this time an evil Decepticon who turned into a gunboat. She was called Thunderblast when the series was dubbed into English. A third character called Chromia was introduced for the 2009 film Transformers: Revenge of the Fallen as one of three Autobot sisters.
Chromia is one of Elita One's most skilled and trusted field commanders. Her flair for battlefield improvisation is legendary, and she is very good at interpreting orders to best fit a changing situation. She is fluid in handling unexpected circumstances and compensating immediately. Chromia is one of many female Autobots that fought alongside Elita One during the Great Cybertronian War. She enjoys her life as a fighter, and shows personality and interests similar to her Autobot love, Ironhide.
One summer day she went away
Gone and left me, she's gone to stay
She's gone, I don't worry
I'm sitting on top of the world
All the summer worked all this fall
Had to take Christmas in my overalls
She's gone, but I don't worry
I'm sitting on top of the world
Going down to the freight yard
Gonna catch me a freight train
Going to leave this town
Worked and got to home
She's gone, but I don't worry
