These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Kamen Rider X
Awesome Music: Totsugeki Kamen Rider X plays during the Apollo Geist vs. X fight.
Memetic Mutation: Starfish Hitler is more well-known in the toku fandom than everything else from the show combined. Even non-Rider fans are familiar with it.
Squick/Nightmare Fuel: In the manga, a female friend of Jin's gets squished by a boulder thrown by a GOD kaijin in EXTREMELY gory fashion.
