Black Assassins are Black Arms soldiers that appear in Shadow the Hedgehog. They are distinguished from Black Warriors by their larger size and the gold-coloured pieces of armour that they wear. These creatures are the elite of the Black Arms army and are only ever encountered aboard the Black Comet.
Assassins are capable of absorbing more damage than Black Warriors and often ride on small hovering saucers. They will also teleport after being attacked, attempting to take enemies by surprise. They are armed with Refractors, energy weapons that shoot red laser beams which bounce off of scenery and other enemies.
