I will go straight to the point, this OC is a total Mary Sue and here's why: 1. 8th princess of the heart. There are SEVEN. Not eight, respect the canon please. 2. "Sora's true love blah blah blah", it speaks for it self. Ridiculous. Sora is already canon with Kairi. I'm not a SoKai shipper, but SoKai is canon: deal with that without doing many problems, you're being childish and you look like a 13 years old possessive fangirl, total cringe. 3. Why she has a Keyblade? WHO passed it to her? You know what is "Keyblade inharence ceremony", right? 4. Keyblade master: it would be ok if only we knew WHO her master is, and Tifa doesn't know. Tifa is not a Keyblade master or a KINGDOM FUCKING HEARTS character. She's a Final Fantasy character, and in Kingdom Hearts FF character are useful as a finger in the ass. 5. In her FaceBook Blog she says that she's a half angel, and this speaks for it self too. 6. Show don't tell rule: as you describe her as OP, perfect, beautiful and so on and say that she's autistic but is that useful to the story? In you're friend fan fiction too: she doesn't SHOW to have autism and I think you're using this thing just for not being criticized, disgusting. 7. "Kairi the Evil bad one! Gne gne! She steals MY Sora, bitch :'(" style mode on: I hear these things from horny 13 years old fan girl, and you're like... 25? 28 years old? And that's pretty embarassing for your age. 8. Perfectioned Self-Insert: this is just your friend but powerful, flawless and without a good logic (she just thinks to drool over Sora instead of thinking about a good characterization or character development or is just me?)

So yeah: this OC to be saved needs to be "built" from the start.
