If you don't know who Eyeless Alice is, let me give you a brief explanation. She is a fan made character who is the daughter of Eyeless Jack and Nina the Killer. I already hate people who make their own OCs based on a relationship between canon characters. But this is a whole other level.
First of all, why can't the appearance be something that isn't a copy? Seriously. She has no eyes with that weird black goo coming from them, razor sharp teeth, a pink streak in her hair, and her dad's mask. Don't forget the grey skin! It's basically copying her parents' styles and giving us a major Mary Sue impression.
Also, when someone is born without eyes, there isn't gaping black sockets. Especially not with black whatever-the-heck-it-is from the sockets. It's actually more of a closed eye look, but not exactly. So either this kid got sacrificed, she gouged her own eyes out, or her parents did it. And the liquid stuff was poured into the sockets. Because obviously she couldn't have been born that way.
I saw a rant about her (which is where I got the idea to write about this from) that said that she shouldn't have been born with grey skin. I actually beg to differ for once. The "incident" with Jack and the cult (I'm guessing) took place before Alice was being created and born. Since hereditary traits are a thing, her skin color could be one of those traits.
The final thing about her looks is that she has her dad's mask. Taking elements from other pastas is not appreciated in the fandom, so a lot of people are annoyed.
Her name is also looked down upon in the category of taking elements/copying. Eyeless Alice, huh? Sounds like the name of dear old dad. It just adds more Mary Sue-nis to her.
In short, she's a Mary Sue among the community with a lot of bad features and little to no backstory or history. Thank you for reading!
