|“||Behold, The Underminer! I'm always beneath you, but NOTHING is beneath ME! I hearby declare war on peace and happiness! Soon all will tremble before ME!||„|
|~ The Underminer|
The Underminer is the final antagonist in the 2004 Pixar film The Incredibles, and the opening antagonist of the upcoming 2018 sequel Incredibles 2. He would serve as the main antagonist in the subsequent video game, The Incredibles: Rise of the Underminer, which is somewhat close to being a sequel to the movie.
He is voiced by Pixar's good luck charm John Ratzenberger, who has played a character in every Pixar film, such as Hamm in the Toy Story movies and his villain counterpart the evil Dr. Porkchop, P.T. Flea in A Bug's Life, and Earl in The Good Dinosaur.
Three months following the defeat of Syndrome, the Underminer appears at the end of the film, where he announces his "war on peace and happiness!" The Parr family then put on their masks, ready for battle. This led to such a cliffhanger leading to the video game.
As the Underminer orders killer robots to rage war on Metroville, Elastigirl and the kids fight off the surface invasion while Mr. Incredible and Frozone follow the Underminer into the depths of his underground city. The Underminer plans are revealed: to activate a machine called the Magnomizer, which would pollute the Earth above. The two super-heroes manage to destroy the machine and the Underminer, ending his war and minions before it began.
- The Underminer is strongly based on the Fantastic 4 villain known as the Mole Man. They both live underground, have an outright hatred of humanity, and they both have a physical resemblance of a mole, especially the Underminer's nose.
