Barney Stormin is a Piston Cup skyrighter that first appeared in Cars, and later made a cameo in Cars 2: The Video Game. He is a Wacool Biplane Co. that is painted red and white, with white designs on his rear half.
In Cars, Barney is writing in the sky above the tie-breaker race at Los Angeles, before quickly flying out of the way as Marco and the other fighter jets come rushing through.
"Barney Stormin is a professional skywriter. His job not only requires aerobatic skill and relatively low winds, but most importantly, good spelling because as Barney likes to say, "There is no eraser in the sky.""
