Overlords are commonly used to scout areas and transport units. They can be occasionally seen excreting creep. Because of their important role and defenselessness, they are common targets for raids in episodes such as Spore Loser. Contrary to StarCraft lore, StarCrafts overlords do not seem to be able to relay commands from the player to the zerg. This role seems to have been inherited by the queens.
Overlords are team-colored with two lighter team-colored helium sacs on the sides of their heads. They have six tentacles and two larger "arms". They almost always have apathetic expressions.
As their expressions suggest, overlords are extremely apathetic and seem to be indifferent to most situations. Most of this stems from the fact that the forces they must oversee show absolutely zero sense of self-preservation whatsoever, and tend to blow themselves up or kill themselves with great frequency. The lot of an Overlord is not for those rattled by losses.
They do, however, take their jobs very seriously; in one episode, when their army went over supply due to a spawning trick, the Overlord had a momentary mental breakdown trying to keep up with it all until, thankfully, an Adept proceeded to murder some of his forces and thus lightened the workload. Overlords dislike being threatened and tend to panic with great frequency, which rarely comes to much as Overlords are exceptionally slow-moving.
Notable Overlords Edit
The scouting overlords are two overlords (one red and one purple). They debuted in Cheeseling, where they scouted the same area and bumped into each other, angering them. When red zerglings passed through the area for an early game rush, the red overlord used its arm to block the purple one's eyes to prevent it from seeing the rush. The overlords later befriended each other in ZvZ, as evidenced by them taking a photo together.
The mineral overlord is a purple overlord who debuted in GL HF when Mineral Drone gave him a mineral crystal, leaving him confused. In an epilogue in the season finale, Mineral Drone frantically signaled to it to evacuate them, but Mineral Overlord was confused and thought it was asking for the mineral crystal back. As a result, Mineral Overlord gave him the crystal and floated away instead of evacuating it, leaving Mineral Drone to die in the lava.
