What is the personality type of Nightmare Sans? Which MBTI personality type best fits? Personality type for Nightmare Sans from Online Fictional Characters and what is the personality traits.
Nightmare Sans personality type is ENTJ, though he is more theoretically introverted.
If you look at the "Recommended by" comments, you can see that people are commenting on his personality, not his appearance. He's not scary, he's not confusing, he's just "creepy" and "odd" and "one of the best remixes of all time".
Nobody is saying that he's scary or confusing, only that he's weird. A fundamental difference between Nightmare Sans and other Freaky Undertale characters.
I think it's very possible he isn't trying to be scary. He's just... different. Different doesn't necessarily mean bad. There are characters in Undertale who are different but amazing. Trickster is one, Mettaton is another, and even the many characters with the same name (and the same personality type) are both very different and not at all bad.
But there is a difference between simply different and actually disturbing. I think that's the difference between Zesty Cream and Zesty Cream's brother.
If you look at Zesty Cream's personality, it is very... interesting.
