Collin Miller

Collin Miller is 15 years old. He has a skill level of 12. Steven and Darren do not like him. In the first Ninja Warrior competition in the winter of 2017, he advanced all the way to the Triple Hurdle in the First Stage, but like Aaron before him, he stumbled and fell on the second hurdle.

In the second Ninja Warrior competition in the winter of 2018, he was the only victim of the new Gateway Bridge.

In the third Ninja Warrior competition in the fall of 2019, he once again had #20, and he wanted to break that curse. He did so by clearing the First Stage, but he was one of many to fail the Floating Bridge in the Second Stage.

In the fourth Ninja Warrior competition on Christmas Day 2020, he was expected to reach the Second Stage again, but he was one of several to fail the Hop Rocket.

In the fifth Ninja Warrior competition in the winter in the first part of 2022, he unexpectedly performed the worst out of anyone. He was the only person to fail at the Barrel Roll in the First Stage.

In the sixth Ninja Warrior competition in the summer of 2022, he got more than halfway through the First Stage, but he once again failed at the Barrel Roll.
