[Comics General] Who would you say is *the best* unpowered/unenhanced martial artist out there? (both Marvel and DC)

I've been browsing a lot of heroes lately and some of them are denominated as a "master martial artist." I wonder though, who is absolutely *the best* one out there? Obviously, for an even playing field, no mutants or powered people allowed. Just average joe humans.

The Karate Kid (DC) has mastered almost all martial arts styles up to the 31st century. He has no powers other then just knowing every single martial art. He regularly fights kryptonians like Super Girl using nothing more then his skill and a flight ring.
