In Pixar's Cars 2, which villainous scientist creates the lemons' weapon?

Professor Zündapp is the villainous scientist behind the lemons' weapon in Pixar's Cars 2.

Zündapp is a German scientist and member of the criminal group known as the lemons. He develops the electromagnetic weapon that makes Allinol-powered cars appear dangerous by triggering violent reactions in their engines.

The scheme is designed to discredit Allinol, an alternative fuel promoted by Miles Axlerod during the World Grand Prix. The lemons want the world to return to petroleum-based fuel, which would increase the value and influence of their companies.

Zündapp is also known as Professor Z. He is pursued by British spy Finn McMissile and secretly works with Axlerod, whose public image as an environmental campaigner conceals his role as the operation's mastermind. The character's name echoes the German motorcycle manufacturer Zündapp.
