he Omnidroid is a series of intelligent and destructive robots developed by Syndrome to fight and kill Supers. Syndrome made many different versions of this battle robot. All were designed to fight and kill Supers, and each subsequent model improved upon the previous one by correcting flaws found during fights. The Omnidroid's only weakness is itself: in the film, Mr. Incredible scrambles into Omnidroid's inner workings, causing the machine to pierce its own hull in a vain attempt to pry the hero out of inside itself.

The Omnidroid series of robots were designed by Syndrome to use AI and destructive features such as claws and lasers to target and destroy its enemies. It is self-learning and can correct its own mistakes, and also collects information on superheroes it encounters.

Omnidroids were used to kill various superheroes - each time a superhero eventually defeated an Omnidroid, data from the nearly destroyed version was then used to create an improved model, specifically designed to have functions to defeat the superhero who had previously destroyed it. Through the instructions of Mirage, the superheroes do not fully destroy the Omnidroid as "it is government property".

The final Omnidroid created by Syndrome was controlled via a remote, which he uses to appear as a Superhero by "destroying" it after launching it himself into Metroville. However, the Omnidroid learns that Syndrome is controlling it and turns on him. The Omnidroid is eventually destroyed by the combined efforts of the Parr family and Frozone.
