- Colbert Bump: The series suddenly received a surge of interest in the West thanks to its inclusion in Super Robot Wars X, which also led to it receiving a page on This Very Wiki and even greenlit another installment despite the last installment not working that well due to a Sequel Gap (as a warning, the 2020 installment has a longer Sequel Gap).
- No Export for You
- Due to the series' kanji-heavy Theme Naming, terminology, and close relations to Chinese mythological roots, the Mashin Hero Wataru Series was one of the only projects to have an exclusive sole-export to Chinese-speaking regions - China, Hong Kong and Taiwan; this led to the franchise receiving widespread popularity within those areas during the mid-1990s.
- Meanwhile, the West's only exposure to Wataru was the famous Keith Courage In Alpha Zones for the TurboGrafx-16 as well as Super Robot Wars X.
- Official Fan-Submitted Content: Given Himiko's endless possibilities of offense, a couple of her ninjitsu were fan-submitted ideas turned canon, which was a lot of fun for Sunrise and their audience.
