Hello! I'm not sure if you still make any yandere headcanons about typology, but I just think about what kind of yandere enneagram types could be (especially I'm interested in 9w8 and 5w6), you can ignore this if you don't want to write something about it or if you have moved away from the topic of mbti and enneagram. Have a nice day!
/also, I’m sorry if I write something incorrect. English is not my first language so there could be mistakes/
Interesting ask you got there! I haven't stopped writing for enneagram and MBTI. It's just not a popular topic around here lol.
*Important note: I am in no way saying that people who have these enneagrams are yanderes or will be yanderes. This is purely for educational and hypothetical discussion of what enneagrams are observed in yanderes within media (i.e., anime). In real life yanderes are dangerous, so please stay away from them. This blog is purely for entertaining a horror trope*
But personally, I would say enneagrams 1, 2, 4, and possibly 6 would usually fit the yandere trope.
Examples: Giorno, Pucci, Bucciarati
pretty self-explanatory if I'm being honest. Enneagram 1s are ruled through fear of being immoral, so they spend a lot of their time trying to live a moral life. However, morals are subjective. What's considered "good" isn't consistent across all people and cultures. I can see these types deluding themselves into being "good" people for darling.
Example: Yan!Giorno kidnapping darling is the "right" thing to do because he can keep them safe from harm
Examples: Jonathan, Yuno Gasai
Highest potential for fulfilling the yandere trope
2s have a fear of being unloved. Therefore, their motivation in life is to act in such a way that they can be loved and accepted. Usually, this is in a form of giving love so they can receive love. It can be excessive where it becomes unhealthy for the individual such as overcompensating, overprotective, overbearing, etc. See where this is going?
4s have a fear of having no identity. Therefore, they spend a lot of time trying to find their own unique identity. Key word is unique. 4s want to be individualistic. To create a sense of self that is unique and self-expressed by them. In a healthy manner, it's great because it means they have a greater sense of self and high self-awareness
however, on the unhealthy side, it can be seen as inherently selfish
this plays a role in the yandere trope because when you think about yanderes, they are pretty selfish when you think about it. They don't take into account their partner's opinions and thoughts in the relationship. I can see 4s almost taking their darling as part of their identity. Kinda the whole "I can't live without you" or "you're my other half" to a whole new level
6 - security and stability
Examples: Diavolo, Narancia
I'm iffy on 6s being yanderes but I put them on the list because I still think they have potential. Tbf, all enneagrams have the potential to be a yandere in their own way, so don't think yanderes can only be these enneagrams!
6s are ruled by their fear of insecurity. They want security, to know that something or someone will work out and be there for the long-run
For the yandere trope, this can definitely be in the form of seeking a partner and wanting them to stay forever. If darling tries to leave this can cause anxiety, that lack of security is no longer there and the enneagram 6 will work towards obtaining that security back
