E522
a model of assassin droid specially commissioned by the Empire and built by Sienar Intelligence Systems, the E522 was characterized by its waspish waist, large shoulders, and squared-off head. This series of droid was produced with an impressive collection of weaponry, both passive and offensive. The E522 was equipped with a heavy repeating blaster, an ion cannon, six hunter-seeker missiles, and a toxin-injection system. It was propelled by a pair of recycled tank treads. Note that Labyrinth of Evil indicates that the E522 assassin droid was produced by the Techno Union during the height of the Clone Wars.
