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. They seemed pretty cowardly, and would usually jump onto a platform and then fire at Ratchet.
