The blastors were the biggest and most powerful of combatrons. They served as an ultimate support to infantry and as the highly mobile artillery units.
The Blastors were towering and hulked machines, taller than Gladiator-class assault walkers. They had long, cylindrical heads with single optic and a couple of antennae. They possessed broad shoulders and bulky chests, but their legs were thick and stubby. They were designed to intimidate the enemy with their sheer size and durability; often they could remain unfazed after receiving a hit from a tank, and then proceed to fight further.
As most of the combatrons, they were slaved to cerebrators. While being the heavy mobile artillery support, their responsive modules allowed them enough flexibility to fight in scuffles taking place in urban areas.
Each Blastor was armed with twin double-barrelled phaser autocannons, semi-automatic weapons used to hold enemy infantry at bay. However, their main weaponry was the set of two powerful, dorsal-mounted retractable pulse cannons. They possessed incredible range and destructive power, with a single cannon being capable of annihilating a Bruiser-class main battle tank. Nevertheless, they required substantial cooldown time between each shot, leaving them vulnerable to damage in the interval of the salvoes.
While rare, these machines caused justifiable fear whenever they appeared on a battlefield. With their impressive firepower and support of the lesser combatrons, they could turn the tides of battle in the favour of the Machines fairly easily. However, even though they were very durable and far from being defenseless, they were susceptible to attacks of infantrymen and air-to-ground strikes. The Robots were aware of these weaknesses, so Blastors never appeared alone, resulting in the situation when those vulnerabilities were extremely hard to utilize.
