The Cowboy Ninja from Salmon, Idaho took on the second stage of finals on "American Ninja Warrior" Monday night.

Lance Pekus finished the first round of finals with the fastest time out of all of the ninjas.

But on Monday, he took on the most challenging obstacle course ever on the season finale of the show.

But the Wingnuts won. Pekus wasn't able to get through Wingnut Alley on Monday night.

But then again, the course proved to tough for all the competitors. The season ended without a winner after all failed to finish the course.
