What is the name of the drill-based villain at the end of The Incredibles?

The drill-based villain at the end of The Incredibles is The Underminer. He emerges from underground in a huge drill-tipped tank and announces a war on peace and happiness.

The Underminer is a mole-like supervillain voiced by John Ratzenberger, a familiar Pixar voice actor. His appearance serves as the first film's cliffhanger: the Parr family has just defeated Syndrome when this new threat rises beneath Metroville. The confrontation continues immediately at the beginning of Incredibles 2.

In the sequel, the Underminer uses his drilling machine to attack the city and rob a bank with a vacuum hose. The Incredibles and Frozone stop the machine, but the battle causes major property damage. That destruction helps prompt the government to shut down the Superhero Relocation Program. The villain is sometimes confused with generic names such as “the Mole” or “the Digger,” but The Underminer is his canonical name.
