ConstructorBots (also known as Flamethrower Bots) were robot enemies found at Outpost X11. They handled a kind of Pyrocitor, which they waved around back and forth in a semi-circle, injuring Ratchet with the flames if they came in contact with the Lombax. For some reason they mistook him for a sandshark, as this was the reason for them attacking him. The ConstructorBots can be seen on top of, or the mid- sections of tall towers in which they can be seen repairing and/or constructing them. Normal sparks shoot out from the base of their flamethrowers when on the towers, suggesting that they can adjust how much power comes from the tool. They seemed pretty cowardly, and would usually jump onto a platform and then fire at Ratchet.
