Jacob Siler

He first competed in American Ninja Warrior 3 where he failed the Soritatsu Kabe. He trained on the warped wall for the following season and went on Northeast Qualfying. He made it all the way to the Soritatsu Kabe, but just like last time, he failed to complete it. However this time he made it to the top 30 as he barely made it with the 30th position. His semi finals run was digested, but it was shown that he failed the Soritatsu Kabe again.

He's the only competitor to fail the Soritatsu Kabe each time he has attempted the course.
