- Both Ninja Ami and Ninja Yumi are hardcore, especially for a show geared towards children.
- Ninja Yumi's mannerisms consist of pure badassery.
- Knoble Knight and Decibel Destroyer count because they are believable manga superheroes.
- Yumi ate tons of tofu dogs against Sauerkraut Malone, to the point where Malone had to give up his golden teeth as a trophy.
- "Five words: Eat my exhaust fumes, (Beat) bucko!"
