The Spiderbots are supporting antagonists the 2009 film 9. They are tiny spider-like robots created by the Fabrication Machine as guards of its factory.
Following the Fabrication Machine's reawakening thanks to a certain talisman, it gathers up the Machines (including the Spiderbots) to lay down a manhunt on several stitchpunks, as the Fabrication Machine intends to absorb their souls to complete itself and finalize its conquest of Earth.
When one of the stitchpunks, 9, sneaks into the Fabrication Machine's factory to rescue 7 and 8, one Spiderbot crawls through a pipe and hides as another Spiderbot goes past a hole. Though 9 was able to rescue 7, 8 ends up being absorbed by the Fabrication Machine, who sends the Spiderbots to go after 7 and 9.
The Spiderbots chase them up the tunnel, but 9 manages to get the other stitchpunks to kick in a barrel filled with an explosive substance. As the stitchpunks escape, the barrel explodes, destroying all of the Spiderbots, Steel Behemoths, and Seeker Drones.
The Spiderbots have fangs like spiders and metal bodies with glowing red eyes. They can squeak and climb on the walls.
