Roach (Legacy of the Void)
With the Tunneling Claws upgrade, the Roach becomes one of two units (the other being the Infestor) that is able to move while burrowed. This is also indicated by the appearance of crystals on the backs of the Roaches.
The Roach is useful in all three match-ups because it can absorb large amounts of damage. Roaches have very high HP values considering their cheap cost. This is augmented by its ability to regenerate its health at a tremendous rate while Burrowed. A Roach can heal itself from 1 to full health in 14 game seconds after the Burrowing and Tunneling Claws upgrades are purchased.
