Hawkeye is one of many power-enhancing Mini-Cons scattered across Earth. A member of the Blue Mini-Con Team, when Powerlinxed to a larger Transformer, Hawkeye equips the larger Transformer with "energon imaging", allowing them to detect other Cybertronic forms by their energon signatures, through blinding snow, dense brush or even solid rock or metal.

Hawkeye's Mini-Con storage panel was discovered on a small icy ledge between two rivers in Antarctica. Following the defeat of Megatron, he and the other Mini-Cons returned to Cybertron and helped form the Matrix Cannon, Nemesis Shield and Vanguard Booster, giving the Autobots the power needed to destroy Unicron.
