In Pixar's Cars 2, which villain is a weapons designer and scientist?

Professor Zündapp is the weapons designer and scientist villain in Pixar's Cars 2.

Professor Zündapp, often called Professor Z, is an eccentric German-designed vehicle who works with Sir Miles Axlerod's plot. He develops the electromagnetic pulse device used in the film's plan to disrupt the World Grand Prix and manipulate the public's view of Allinol fuel.

The character's name references Ferdinand Porsche's Zündapp prototype, although the film's villain is a fictional creation. His appearance and role fit Cars 2's spy-thriller style, which expands the series beyond Radiator Springs and introduces international locations and espionage characters.

Finn McMissile is a British spy who opposes the conspiracy, while Miles Axlerod is the scheme's central organizer. Those characters are therefore related to Professor Zündapp but are not the scientist described in the question.
