National Champions is purely fictional. It doesn't have its roots in any actual events or people. The story was crafted to engage and captivate the audience through imagination and creativity rather than reflecting real-life happenings.
The theme of self - discovery could also be in it. As they strive for the national champion title, they may learn more about themselves, their capabilities, and their limits. They might find new aspects of their skills or personalities that help them in their journey to become champions. For example, an athlete may discover a new training method that suits them better during their pursuit of the national championship.
