American Ninja Warrior Junior[]
Jonah first competed in Episode 5, specifically Bracket 3, for American Ninja Warrior Junior. Competing against Nate Pardo in the Seeding Round, he unfortunately lost the race against Pardo. Then, in the Knockout Round, Brown beat out Maggie Owen in the race, advancing to the Final Showdown. But Brown ended up losing the Showdown against Nate Pardo, meaning he did not move on.
American Ninja Warrior 16[]
Jonah returned to the course in American Ninja Warrior 16. In Qualifying, Jonah completed the course with the fastest time in the first qualifier. Since he cleared in under 1:20, he also got to attempt the Mega Wall. However, he failed to complete it.
Jonah raced Jonas Harmer during the Semifinals. His race was digested, but while Jonas failed Wingnuts, Jonah cleared the course, earning his first trip to the National Finals.
Jonah was digested once again at the national finals on Stage One, but he failed the Giant Rollercoaster after the bar on the first track went off the track, causing him to land on the ground underneath the platform, ending his rookie season.
