This is the Nakarkos or Osutogaroa armor from Monster Hunter Generations.
I built this armor last year to compete in the Fan Expo Master of Cosplay competition. It took about 4 months (over 600 hours and 700 dollars) The abdominal plates, mask, arm and leg armor, and skirt sides are all hand tooled and shaped leather, patterned and made by me. The sword and teal parts all light up with neopixels and there is also a smoke machine in the mouth of the sword. The helmet, chest cover, shoulders, and belt parts are all carved EVA foam.
