Although he has adapted his skills to war, Mirage has never truly been a soldier. Formerly an aristocrat living a luxurious lifestyle, he fights only because he has been forced to do so. After the defeat of Unicron and the start of the new Golden Age, Mirage returned to his home planet in hopes of once again finding peace.
However he soon found that his beloved Cybertron faced a new threat – the Machine Wars. He teamed with the Earth-born Autobot Electrons to provide upgrades to the world's population, preparing them for the upcoming battle. He even opted to take a few of the upgrades for himself, increasing his speed by a factor of 2. He has also exposed himself to the highly contentious Forestonite, which has enhanced the range of his invisibility field tremendously.
