#9 Jeff Hardy
Most pro wrestlers don't face paint as a way of hiding their true identity or making themselves seem mysterious. Jeff Hardy was already a well-known name and well-known face in pro wrestling when he started using face paint in the early 2000s.
Following The Hardy Boys' split, Jeff went to SmackDown and began climbing the ladder to the main event. To distinguish his new singles career from his time teaming with Matt, he started using face paint.
Jeff Hardy is an accomplished artist outside the ring as well as inside it, and his face paint is often aesthetically pleasing yet disturbing. This is an example of a wrestler using his face paint to enhance an existing character, rather than trying to transform into a new one.
Jeff Hardy still breaks out the face paint when the mood strikes him, as seen during recent runs on SmackDown Live.
