|“||Behold, the Underminer! I am always beneath you but nothing is beneath me! I hearby declare war on peace and happiness! Soon all will tremble before me!||„|
| ~ The Underminer's speech.|
The Underminer is a recurring antagonist in the Incredibles franchise. He serves as the final antagonist of The Incredibles, and as the secondary antagonist of Incredibles 2. He also appeared with greater roles as the main antagonist of the spin-off videogame The Incredibles: Rise of the Underminer and later as a major antagonist in The Incredibles comics by Boom! Studios.
Three months following the defeat of Syndrome and the Omnidroids, 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 to battle against him.
Immediately after the events of the first film, the Underminer's drill begins tunneling downwards, with Mr. Incredible struggling to break into it. At a certain depth, the Underminer detonates several bombs, which causes the Metroville Municipal Bank to fall down below. As the Underminer loots the safe, he is confronted by Mr. Incredible, who he engages in combat. He commands his drill to dig upwards, forcing Mr. Incredible to abandon pursuing him and allowing him to slip away. The Incredibles successfully prevent the drill from destroying the city, but at the cost of thwarting the Underminer and their chance for becoming legal again.
By the end of the film following the arrest of Screenslaver, it is likely that the Underminer is still at large as supers have been declared legal again. In the film's post-credits scene, it is shown that the Underminer is still driving his driller to an unspecified location, likely to avoid being discovered by the authorities.
The Incredibles: Rise of the Underminer
Following where the first film left off, the Underminer orders killer robots to rage war on Metroville, and 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's plans are then revealed: to activate a machine called the Magnomizer, which would pollute the Earth above. The two superheroes manage to destroy the machine and the Underminer, ending his war and minions before it began. This is an alternative timeline as he returns in Incredibles 2.

- 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. They are also obese depending on the version.
- He and Bomb Voyage are the only villains in the series to succeed in their plan.
- It is possible that he is inspired by Gaetan Molière, a villain-turned-hero in the 2001 Disney animated film Atlantis: The Lost Empire, as both like to burrow, use old equipment, are squat and have buck teeth.
- Many have complained that after his speech in the first film, it makes no sense for the Underminer to just be a bank robber, when it was implied he wanted to wage war on the surface world. Many prefer his depiction in the video game.
