Charlie Ball Sets Stage in ‘American Ninja Warrior’ Return

From Junior Champion to National Stage

Charlie Ball, a 16‑year‑old from Readington, New Jersey, has built a reputation that stretches back to his early days on two seasons of “American Ninja Warrior Junior.” He first competed at ages 9 and 11, earning the nickname “Unstoppa‑Ball” that still follows him today. The exposure he gained in the kids’ series planted the seeds for his recent move to the adult competition.

Ball made his rookie appearance on Season 18 of NBC’s “American Ninja Warrior” in June 2025, finishing fourth in the June 29 episode and securing a coveted bye into the semifinals. His next head‑to‑head race is slated for July 13, where he will face two other ninjas on identical courses. The youngster taped his runs in Las Vegas, a fact that adds to the prestige of his debut.

A Lightning‑Fast Run on Season 18

During his first adult run, Ball completed the seeding course in 57 seconds, navigating six obstacles: Shrinking Steps, Rollercoaster, Domino Effect, Kite Surfer, Wall to Wall and the Mega Wall—an imposing 18.5‑foot Warped Wall. By blasting through the first five obstacles in under a minute, he unlocked the Mega Wall challenge and posted one of the fastest times of the night.

Commentator and co‑host Akbar Gbaja‑Biamila had spotlighted Ball as “the pick to be the fastest time of the night,” and Ball delivered under pressure. “It was super,” Ball said, reflecting on the transition from the kids show. “It was very different… I definitely felt the different atmosphere. I was super nervous, but it was good.” Once the course began, his nerves vanished and he focused on the challenges ahead.

Life Off the Obstacles: Coaching and Community

Since discovering the sport at age 4 while watching “American Ninja Warrior” with his family, Ball has never lost his passion for ninja competition. He began imitating the athletes he saw on TV and officially started training in 2018. Today he trains four to five times a week and has added a new identity: Coach Charlie.

Ball now teaches younger athletes at Next Level gym in Flemington, where he trains alongside fellow ninjas Abby Clark and Joseph Capobianco. “I have the same love for it that I always have had,” he said, noting that the dynamic has flipped—he is now the role model many kids look up to. His advice to young competitors is simple: enjoy the sport and let that love fuel consistent work rather than tying self‑worth to performance.

Looking Ahead to the Semifinals

Viewers will see Ball return to the competition on July 13 for the racing portion, where he will face off against two other ninjas on identical courses. His future in the series appears bright; he told reporters, “I definitely plan to be there… I just have to fill out the application.” That ambition reflects a broader commitment that began when he first imitated televised ninjas as a preschooler.

Ball’s journey from a backyard imitator to a featured rookie on national television highlights how early exposure can shape a lifelong passion. As he continues to train, coach, and compete, his story serves as a roadmap for young athletes dreaming of joining the ninja elite.
