I don’t think he will return, especially since John Ratzenberger is no longer in every Pixar movie. And even if he still was in every Pixar movie, they could always find a different role for him to play in Incredibles 3. But as for the Underminer, I think he’s long gone.

I had an idea for what Cars 4 could be about. It’d be similar to Cars 2, and the two spy cars would return. This time they’re exposing a cabal of chop shop operations, which would basically be the equivalent of the organ trade.

The opening is Mater talking to a chop shop operator, and initially the conversation appears like they’re fixing the cars, not dismantling them. Mater finds one of the missing cars, and starts rescuing him, when he’s caught by the chop shop owners.

It jumps back to a few months earlier, with Mater aiding Cruz with her racing career, and Holley approaches him after the race. She lets him know about a mission they could use his help with, something that he is uniquely suited to doing: towing cars to safety, and saving them from being dismantled.

Lightning uses his connections in the racing world to find out more about what happened to the missing cars, some of which were former racers that Lightning knew.
