This is a partial character sheet for Kamen Rider Amazons. Visit here for the main character index. Subjective trope and audience reactions should go on the YMMV page.
Tropes Applying to Amazons in general:
Always Chaotic Evil: Once they hit the 'fully awakened' stage. Before that, Amazons like Mamoru, Jin, and Haruka can be kept in control. After that? They become mindless beasts with a craving for human flesh.
Artificial Human: The Amazons are this, being made of artificial virus-sized life forms called Amazon Cells.
Being Evil Sucks: The majority of Amazons would be perfectly happy to live normal lives if it weren't for the unfortunate fact they have a Horror Hunger for human flesh and will turn into man-eating monsters whether they want to or not.
HeelFace Revolving Door: Somewhat. The surviving Amazons that witnessed Haruka's fight with Jin do not attack the reformed NPS and leaves with Haruka and Mamoru without incident. A noticeable one is a Bat and Crab Amazons.
Horror Hunger: Once they transform fully, they gain a hunger for human cells.
Hyperactive Metabolism: As shown with Mamoru and Haruka, they burn through food really quick in their monster form (which it seems most Amazons are mode locked into), and a quick bite can restore their strength.
Picky People Eater: FRESH human protein is the only food they can stomach when they're far gone. Refrigerating it helps maintain the appeal, but a few minutes after the human dies, their flash becomes completely unpalatable to awakened Amazons. Savvy Amazons try to get around this problem by eating their prey very fast; others go the opposite route.
Power-Up Food: Anything with protein, especially humans, can power them up if they get enough.
Random Power Ranking: Amazons are rated from E to A as a measure of how dangerous they are. However, it should be noted that this ranking refers to their initial level, and they can potentially grow stronger, as shown with the Queen Ant.
To Serve Man: Exclusively go after humans. Justified, as their Amazon Cells go for human cells, so they're instinctively driven to eat humans. However, ones that manage to keep themselves under control in some way (like Jin, Haruka, and Mamoru) only need stuff high in protein, not specifically human protein.
Tragic Monster: Were created in a lab, and seem to have been trying to live life as normal humans, but ultimately once the medicine in their armlets runs dry, they will transform into man-eating monsters with no humanity left and unable to control their actions.
Hive Queen: As the Peston Service finds out to their horror, her apartment building is invested by another 182 Ant Amazons.
It Can Think: While not seeming to retain her humanity or be quite as smart as a normal human, she's the first Amazon to imitate one and use complex plans to lure them into a trap where she can kill them. She's also smart enough to retreat and eat to regain her strength after getting attacked by Haruka.
Non-Mammal Mammaries: It's especially jarring when they found the biggest suit actor they had to be this creature.
Devoured by the Horde: The most dangerous thing about fighting them is that they're mindless berserk Amazons in a large group. Kota would've suffered this fate had he not managed to set off the sprinklers and fumigate the entire building with Anti Amazon gas.
It Can Think: Averted. Unlike their queen, they're all dumb as bricks and can be distracted by loud noises. That moment of distraction saves Kota's life when he sets off the sprinklers and by proxy the fire alarm.
Mooks: Are Rank E and serve the Queen. While there are 182 of the blasted things, individually they're extremely easy to kill to the point the Amazon Riders can rip them apart with ease and the Peston Service can hold their own against them one on one. The problem is there's 182 of them!
Zerg Rush: Individually they're not very strong at all, but the issue is there's nearly 200 of them in one place.
Butterfly Amazon #1
It Can Think: Much like the Queen Ant Amazon, he came up with a complex plan for gathering food. unlike her, he's not actually a berserk Amazon.
Affably Evil: He's very polite and soft-spoken to the Amazons in his restaurant, and always wants to reassure them if they feel uncomfortable. He also cooks unsuspecting humans with a big smile on his face. Even while he's in the face of danger, he tells his customers to escape so they don't get killed.
To Serve Man: His entire MO is to kill humans and feed them to the Unawakened Amazons at his restaurant.
Unwitting Instigator of Doom: Much of Season 2's plot and main conflict can be indirectly pinned on him, as Mamoru chancing across one of his 'manburgers' causes his partial awakening, forcing him to leave human society at the end of Season 1.
Villainous Breakdown: It's ambiguous exactly how "villainous" he is, but he starts losing it when his plans go down the tubes and His Amazons Register indicates he's awakening.
Well-Intentioned Extremist: He sincerely believes that eating human flesh will slow the process of an Amazon's awakening, and seeks to continue gathering meat for his "patrons"
Bait-and-Switch: We're led to believe the Rose Amazon is a beautician working at a salon who decapitates her victims. The Amazon turns out to be her boyfriend, and understandably gets enraged when 4C wounds her while assuming she was the Amazon.
Tragic Villain: Shuuya is an example of an Amazon that tries to live a normal life with a human fiancee named Emily. However, she gets shot and he kills those involved. When he sees Emily, he decapitates her to end her suffering. Then he dies at the hands of Omega and Neo.
