Sadodere is a Japanese character archetype that involves sadism. They are quite malicious like yandere, but they are not the same character archetype. The similarities of yandere and sadodere cause fans to either mix them or become confused with them.
A "Kamidere" refers to a character with a god complex, making them self-centered and arrogant towards those they see as inferior to them and who are not deserving of their time. They will demand to be treated like the perfect being they think they are by others, included those they like.
Yadere are most often female characters, but male examples do exist. However, when they appear, they may sometimes be referred to as “male yandere” to differentiate them from the umarked female yandere. A concept closely related to yandere is yangire.
There are a handful of examples of dorodere in Japanese popular culture, such as Alluka Zoldyck from Hunter X Hunter, Kanato Sakamaki from DIABOLIK LOVERS, Juuzou Suzuya from Tokyo Ghoul, Nagito Komaeda from Danganronpa, Reisuke Houjou from Mirai Nikki, Shiro from Deadman Wonderland, and Tsukasa Yugi from Jibaku ...
The word "dere" comes from "deredere" (デレデレ), an onomatopoeia meaning "lovestruck" or "lovey dovey". Dere type characters are characters that express their affection in different ways, or on different levels. Most of the dere types are how characters react to becoming lovestruck.
Then you're probably familiar with the Japanese term 'dere' which comes from the phrase 'dere dere' meaning to be lovestruck. You might recognize these Big Five Dere types in an anime or manga: Deredere, Tsundere, Yandere, Kuudere, and Dandere.
Nearly every example of a yandere in fiction is somewhat of a toxic character. At best these characters tend to have an unhealthy attachment to their love interest. More often however, the yandere characters are emotionally and/or physically abusive to their love interest and the people around them.
The character that inspired my consideration of different yandere archetypes is actually Toga Himiko from My Hero Academia, whom I would call a “modern yandere.” A supervillain who gains power from inflicting large wounds and draining blood from her victims, her ideal man is someone who looks like he's been beaten ...
It's also a type of pizza too. Then there's “yandere,” someone who expresses their intense love through insane, sometimes violent, methods. While typically relegated to the 2-D realm, apparently yandere exist in real life too, as was seen recently when Japanese Twitter user @hanahanakaidou made this post: ▼ “Oh god…”
Miku may be a kuudere, but when the time comes, her emotionless exterior melts. Throughout Quintessential Quintuplets, she has shown an array of different expressions, ranging from surprise to embarrassment.
