Acer

Acer is one of the villains in Cars 2. He works as a henchman for Professor Z.

Official Description
Acer has always felt like an outcast in the car world. The beat-up green AMC Pacer joined forces with fellow “lemon” cars as henchmen for the devious Professor Z, whose clandestine mission is to wreak havoc at the highly visible World Grand Prix. Acer must hunt down the American and British secret agents who’ve stolen crucial information about Professor Z’s underhanded plot—his primary target just happens to be Mater, who’s been mistaken for a spy. Acer tries very hard to be a tough guy, but he’s over-eager compared to his no-nonsense accomplice Grem.
