We must fight alongside our enemy against a common threat.
Overcast is the long-lost brother of Jetfire and has been a loner for many eons, refusing to get involved in the conflict with the Decepticons. Overcast had a change of heart after witnessing the destruction of one of his favorite planets at the hands of Unicron. He then realized that this battle extends well beyond a simple conflict between Autobot and Decepticon. He has since joined his brother in battle against Megatron in order to avoid the potential revival of their common enemy. Like Jetfire, Overcast is a fast and powerful warrior whose impressive skills have served the Autobots well during battle with the Decepticons.
