RK-7, a B1-series battle droid, fought for the Trade Federation in the Second Battle of Theed. He held the rank of commander, leading a squad of ten other battle droids.
In the course of the conflict, Viceroy Nute Gunray tasked RK-7 and his unit with the protection of Gode Takrab's shuttle. This assignment was intended to either support Takrab's objectives or, if those failed, to serve Gunray's own plans. RK-7 endeavored to prevent the Naboo Resistance from seizing the shuttle, despite his lack of complete knowledge regarding the mission's true nature.
