When the UFC was formed in 1993 there was one simple purpose: Determine which form of martial art was the most effective in a real fight (although the fans didn't know the answer was essentially predetermined to be Brazilian Jiu-Jitsu).
As a proving ground for martial arts, the UFC attracted a number of the more...enigmatic and downright strange forms of combat.
Some were self-formed, some had been crafted over generations, but they were all out of the ordinary.
So, here are 13 of the strangest (or most unique or whatever synonym you choose) fighting styles to grace the octagon.
Please note, it is difficult to quantify "strangeness," so these aren't ranked per se but rather go from the least "strange" to the most.
