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.
Americans Hate Tingle - Masato Kusaka is a fan favorite in Japan. Kamen Rider fans from just about everywhere else, on the other hand, absolutely loathe him for being a smug, petty-minded Jerkass.
Badass Decay - Takuma. At first, he's able to curbstomp all three Renegades on his lonesome, is enough for one of them in human form, will kick your ass with poetry, and at one point wields the stolen Faiz Gear against the good guys (admittedly, though, that last seems to happen a lot.) Later in the series, he's a constantly weepy, whimpering Butt Monkey. Takuma circa #20 and Takuma circa #40 have zero in common and not in a good way.
Magnificent Bastard - Masato Kusaka. He's a scheming Jerkass of epic proportions, and the epic proportions are what make him fun to watch. He's basically a "good guy" version of The Starscream (and the term "good guy" is used very loosely—he's only a "good guy" because he hates the villains only slightly more than he hates the heroes). He's popular in Japan, but the popularity could be the enjoyment of a good bad guy. He really is the series' best villain, and a rare instance of it being shown that not everyone who doesn't want the apocalypse is necessarily a sweetheart in all (or any!) other ways.
Memetic Sex God - The Faiz Gear's voice. Standing by. Complete.
Narm - Possibly when Dragon Orphenoch stopped beating up Faiz due to a toy airplane.
Nightmare Fuel - Just how do Orphnochs kill and/or turn a human? By having tentacles enter their insides and go into the heart (Though Kiba just downright stabs the heart with his sword), shown rather graphically (against a backdrop of a chest X-ray, thankfully).But Wait, There's More!. Said target then continues to live for a few minutes, wandering in some confusion before dying and turning into dust... or reviving as an Orphnoch.
How could you forget that said heart bursts into flames and disintegrates into nothing?
The scene showing the Orphnoch King eating an Orphnoch. Petrifying it first, then breaking its face off and eating it with crunching noises, then opens its mouth with a simple but HORRIBLY disturbing CGI effect.
It's also scary because the body of the first petrified Orphenoch, which the King didn't get to eat, was pretty much indestructible. That makes it freakier.
Same thing for Kitazaki's actor, Ray Fujita, better known as Rei Suzumura from Garo.
What Do You Mean, It's for Kids? - With the dark, serious tone of the show, one could easily mistake this TV Asahi Sunday morning program for an adults' show.
Women In Refrigerators - With the only female Rider in this series - the original Delta - getting killed just before suiting up for her first fight after we find out that Samus Is a Girl, the female Rider curse that will go unbroken until Kamen Rider Decade has its most glaring example in this series.
The Woobie: Kiba is established as this in episode 1. He wakes up after a 2 year coma and it's revealed his previous happy life is no more. His parents are dead, his girlfriend hooked up with someone else and his house is sold because his corrupt uncle needed money.
Yuka gets it just as bad. She's not only The Unfavorite and has to deal with Abusive Parents who absurdly dote on her (half? step? foster?) sister, but said sister is an Ungrateful Bitch who, after Yuka brings their parents to her when she gets hurt, lies off her ass and tells them that it's Yuka's fault in the first place. Apparently, Yuka's property is also routinely stolen and/or destroyed at school. In an early episode, a group of girls tackle her to the floor and steal her shoes and socks - the next time she sees her stuff, it's torn and cut to pieces. Is it any wonder that when she first became an Orphenoch, she took no prisoners?
