|~ The Underminer|
The Underminer is a villain that appeared at the very last minute in the Pixar movie, The Incredibles. He is then the main villain as well as the final boss in the subsequent video game; The Incredibles: Rise of the Underminer which is somewhat close to being a sequel to the movie.
The Underminer is voiced by John Ratzenburger.
As the Underminer orders killer robots to rage war on Metroville, Helen, Violet, Dash and Jack-Jack fight off the surface invasion and 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.
