Which Pixar film introduced the character Miles Axlerod?

Cars 2 introduced the character Miles Axlerod.

Axlerod is presented as a former oil baron who has converted himself into an electric car and founded the World Grand Prix. He promotes Allinol, a supposedly clean alternative fuel, and becomes a central figure in the movie's espionage storyline.

As the plot develops, Axlerod is revealed to be the mastermind behind the conspiracy targeting cars that use Allinol. His plan uses the fuel's vulnerabilities to create chaos and discredit alternative energy. The revelation gives Cars 2 a villain whose identity is tied directly to its themes of fuel, technology, and international competition.

Axlerod is voiced by Eddie Izzard. He is a separate character from Professor Zündapp, the German scientist who helps carry out the plot, and from Chick Hicks, the racer associated with the first film. Cars 2 is therefore the specific entry that establishes Axlerod's role in the Cars universe.
