We love to watch the fearless nature that many of our favorite sports stars exude in their respective games. But even professional stars have to feel a little scared of their competition from time to time, right? To celebrate Halloween, Athlon Sports asked hundreds of pro athletes, "Which athlete scares you the most?" Here are our favorite responses.

Our favorite athletes play their respective games with reckless abandon, often making the very difficult look very easy. But we all know there has to be some internal fear during the highest level of competition.
