Imperial Senate Guards were decedents of Galactic Republic Senate Guards. They wore blue and black armor and used Lightsaber Pikes, like the Shadow Guard. They were part of the Senate Building Security forces, and were mostly stationed on Coruscant, but sometimes escorted Senators and other officials to different planets.
The Senate Guards were the lowest ranking of the Emperor's Guardsmen. They were often paired with Royal Guards and Shadow Guards. These units also used thermal detonators and were trained different martial arts. The Senate Guards were deadly foes to the Rebellion's troops.
