Acer is the scientist who works for Professor Zündapp in Pixar’s Cars 2.
Acer is an assistant and technical specialist connected to Zündapp’s plot to disrupt the World Grand Prix. He helps develop and handle the equipment used in the scheme, which involves an electromagnetic pulse device and a stolen form of Allinol fuel. Acer is identified by his green AMC Pacer-inspired design.
Cars 2 expands the series from Radiator Springs into an international spy adventure. Mater becomes involved after being mistaken for an undercover agent, while Lightning McQueen competes in races held in Japan, Italy, and England. Finn McMissile and Holley Shiftwell are the actual espionage professionals trying to stop the conspiracy.
Grem is another henchman, and Rod Redline is an American agent whose early capture helps launch the story. Those characters are connected to the same plot, but Acer is the scientist working with Professor Zündapp.
