These robot minions are sent by the Darkness to hunt down whatever it desires. They sometimes exhibit some signs of humanity, a few even taking more interest in having fun than completing their orders, but are otherwise mindless drones. They chase after Timmy Turner and manage to capture most of his friends and family, but are otherwise easily dispatched on several occasions by Poof or Timmy when he had access to ancient magic.
They are silver/gray colored robots with spiked shoulders. Their helmets vaguely resemble the same one worn by Dark Laser. They are able to create some sort of portal to the inside of the Darkness with their mouths. Their dialog mostly consists of saying "Eliminate Timmy Turner".
When the Darkness first appeared on the super hero planet of Wonder World, the citizens were frightened by its appearance and so they attacked it with the planet's main weapon the "Thunder Rockets", but instead of harming it The Darkness absorbed the rockets and recycled them into the Eliminators who, from then on, would act as The Darkness' guardians and servants.
