Protoss-colossus

The colossus is an antiquated protoss war machine, dating back to the Kalath Intercession. It is unique in that it was created purely as a war machine, in contrast to most protoss automatons which are mainly created for industrial and/or resource gathering purposes. Such a trait was demonstrated by the mass slaughter carried out against the kalathi, appalling the protoss. As such, the Conclave outlawed the manufacture of colossi, and existing machines were deactivated before being sealed away in distant asteroids and uninhabited moons. The war against the zerg, however, has prompted the protoss to reinstate the colossus as part of their arsenal.

The colossus is a towering construct, striding across the battlefield on four tall, slender legs which give it an extremely high level of mobility. The great height of the machine allows it to step up and down cliffs and other steep elevations with little difficulty, and gives it a dominating field of fire. The heavily armored hull of the Colossus carries two powerful thermal lances: one mounted on each side of its body. Complex focusing and targeting systems are used to pinpoint the continuous damage output of the thermal lances for optimal efficiency. A colossus' beam cuts a fiery swathe of destruction through multiple enemies with each firing cycle.
