Why is Meiko always the bad guy???

This is like asking....
Why does Len always die?
Why is Rin always bossy?
Why is Miku always sweet?

Going off of what zerowakakkoi said, and especially since you're talking about fanfictions and not songs; basically the Популярное headcanon of Meiko is that she's older than most of the other Vocaloids, drinks, and isn't totally a nice person.

Also, Meiko, while a lot of people know her; she's not as Популярное when compared to the other well known Вокалоид (Miku, Rin, Len, etc.) so people are probably also еще willing to make her the villain than other Вокалоид that they like, that's kinda my own personal speculation.

Long story short, don't take peoples hate Комментарии against Meiko personal, it's just like Ты say; it isn't true. Crypton has not дана any of their Вокалоид ANY canon personalities, traits, items, etc. there are just things, like Meiko's sake, that are widely accepted headcannons.

I dunno. Meiko is cool

I know right? No matter where I go it's always Meiko being evil. I don't think she's actually evil. I think she's actually a nice person.

I don't really know since she is very motherly and kind , but probably just some idiot haters или Mikutard . I guess she is being the bad guy in KaiMi Фан fiction right ? . but she wasn't always being a bad guy , for example read some KaiMei fanfic.

They're n00bs. They're going to put a lot of clichés in there, especially Meiko being the bad guy and Miku being the good girl. If Ты headcanon the opposite, then that's okay. Опубликовать it on the web if Ты want to.

IDK. Maybe she's not Популярное или that the Vocaloid staff don't like her.
