One of Click and Clack's mechanics, Fidel thinks of himself as more of an automotive consultant and prefers never to stain the spotless Armani suits that he wears to work at the garage everyday. Click and Clack are well aware of Fidel's peculiarities, but also know that he's a genius at diagnosing car trouble. How much of a genius? Fidel can tell what's wrong with a car by just listening and smelling - almost the way a dog smells fear. Fidel also has an eye for the ladies, although the favor is not returned; women are only too aware of Fidel's inability to pass a chrome bumper without checking his reflection.
