A lot of tropes from the Japanese and American versions probably apply here too.
Ninja Warrior UK contains examples of the following tropes:
- Downer Ending: Nobody completed Stage 2 in the series 1 final.
- Joke Character: There's definitely a few of these, just like SASUKE.
- Difficulty by Region: Obstacles are MUCH easier than in the US version. The Warped Wall is 10.5 inches shorter and the ring toss pins are closer together. Justified by the fact that the UK series is only a few years old, while the American version has been going on for 10 years, and the Japanese versions has been going on for 20 years.
- Spiritual Successor: The BBC axed Total Wipeout. ITV took the opportunity to bring over the very format that inspired Wipeout in the first place!
