Tubbs Pacer is a gold and brownish pacer who works for Professor Z. He is head of the Pacer family. During the film, Tubbs and the the other main heads of the three lemon families (Gremlin, Trunkov, Hugo) attend a meeting with Professor Z in Porto Corsa to discuss their evil plans about discrediting the Allinol by using the radiation disguised camera to crash out the racers in the World Grand Prix that use the gas, and ensure that all cars keep using conventional fuel to secure the profits of their "lemon" organization who managed to secure the largest unexplored oil resources in the world. Tubbs is seen smiling at the idea and can't wait.
Near the end of the film, Tubbs gets spray painted by Ramone, and is arrested in London with fellow lemons.
