Sean “Mitoman” Loughlin, a 15-year-old from Boonsboro, Maryland, has demonstrated resilience and determination on the ‘American Ninja Warrior’ stage, competing while managing mitochondrial disease. The condition affects his body’s cellular energy production, requiring him to be connected to a feeding tube for 20 hours daily. He only disconnects from his feeding pump for training and competition.

Despite his physical limitations, Loughlin trains rigorously, inspired by his participation in the show. "Because I get to do ninja, it makes my life 100 times better," he stated. His mother, Christine, expressed immense pride in his dedication, noting, "It’s just incredible that he can do this stuff."

During his run on the show, Loughlin, who weighs 94 pounds and stands 5’1”, proved to be the lightest contestant of the night. He navigated early obstacles, including the Shrinking Steps and Rollercoaster, with ease. Although he experienced a minor slip on the Domino Effect, he recovered. His smaller frame presented a challenge at the Wall to Wall obstacle, but he persevered.

Loughlin reached the final obstacle, the Warped Wall, with the audience cheering him on. After a near miss on his first attempt and visible effort on his second, he succeeded on his final try, hitting the buzzer at 3:15.60. When asked if he ever doubted himself, Loughlin responded, “No. Never planned on giving up. Always gonna give it my all.”

‘American Ninja Warrior’ airs on NBC at 9/8c.
