The Underminer

Behold, The Underminer! He is always beneath the wiki, but nothing is beneath him. He seeks to destroy peace and happiness in the wiki forever.

Near the end of the film, he appears from a gigantic drill vehicle to show his existence, prompting the Parr family to spring into action and serving to demonstrate that they will go on to have many adventures and fight various enemies as a superhero team.

Incredibles 2

The Underminer appears in a flashback by Tony Rydinger, in which he is saying his famous quote, in which Tony runs away and hides under a car from him. He is also booked as a Terrorist and Bank Robber, which were not present traits in Rise of The Underminer, released 13 years before.

The Underminer uses a vacuum to suck up money from the bank in which Mr. Incredible tries to prevent him from doing so, after being sucked up into the machine. He breaks out, and tries to fight Underminer, as he sets off bombs to destroy buildings above.

He later escapes with the stolen money, leaving his machine to knock down the Town Hall, which Frozone barely prevents from doing so. Afterwards, it is unknown what happened to the Underminer since he is never seen again afterwards and only mentioned a few times more (such as the part where two detectives question Mr. Incredible and Elastigirl to know if they stopped the Underminer from succeeding his mission to which Mr. Incredible explains that his family failed to do so). However, during the credits, the Underminer can be seen in his drill machine coming up off of the ground.
