Onyx a Mary-Sue?

We all know what Mary-Sues are right? If not, Mary Sues are female characters that are too over powered, over sexualized, sometimes the creator themselves in the fandom, too pretty, "perfect" and etc. They're bad and they exist in both OCs and in Canons as well. Mary Sues are often paired with one canon or sometimes more than one canon and they could also be paired with an OC or multiple OCs and sometimes they're paired with both Canon and OCs. And when paired with canon(s), they sometimes do a horrible job at making their couple a possibility ... Usually there is no story to the characters, or sometime the stories don't make sense at all. Cross overs are often involved and .... sometimes the creator lacks creativity at creating multiple OCs. Get the idea?

But Onyx?! NAH! ... Could she?

This is something I have been denying. I seriously think Onyx is not a Mary-Sue... but I have been watching some rant videos, reading Mary Sue rant journals, looking at Mary-Sues themselves and I have come to the conclusion people who own Mary-Sues have a formula on what makes Mary-Sues ... Mary-Sues. 

I do not support Mary-Sues in anyway! I will admit when I was younger, yeah Onyx/Rosie was a Mary-Sue! A HUGE one too! But as I grew and started to change my OCs' looks, I started to make more, I guess "adult decisions" on who my character is, what makes her that way, how she interacts with the canons, and why she's there. But I started thinking a lot about Onyx and well ... Is she a Mary-Sue? I believe she isn't! But what do you think? She sorta follows the Mary-Sue formula! 

Sad backstory
Hooks up with a canon from the Archie Comics
Shadow shows interest in her
She gets raped (spoiler)
Acts similarly as Shadow (compatibility) 
A creation
Immortal (by age)
Dark abilities only she can use 
Possibly OP 
She is a weapon 
Sexy appearance 
Boobs

Eeeeeesssssssssssshhhhhhhhhh. I guess boobs don't apply since they are not meant to be huge. I don't wan't to use the excuse that my style is sexy and it gives off that impression ... but I do enjoy making female OCs very sexy. Over exaggerated body proportions, thin waists, big hips, strong or sometimes thin legs. UGH! My Pony OCs are probably the only OCs that are not Mary-Sue at all since all are pretty much AU (Alternate Universe) and don't interact much with the main 6 or the background 6. 

Anyway, could Onyx possibly pass as a Mary-Sue? 

Why Onyx? Well if you didn't know, Onyx is my one Sonic OC that I have worked on for years! Literally years! She is my main character, along with a few, that exists in the canon world and interacts with the gang. She's my baby ;^; and I truly believe that if by any a chance, a miracle from God, Archie SEGA or SEGA themselves were to have an opening for new character, Onyx could possibly fit! (I can only dream, right?) Not trying to say that other amazing OCs can't compare to mines, just saying if there were to be an opportunity like that, then Onyx could fit! Her story is linked with the Mobius Universe! But that's just a dream ... I do plan on making two versions to this story! The story I planned and the story that would be "SEGA" friendly.

But really, could Onyx be a Mary-Sue? If so, how? I'd like to hear your opinions and be honest! I can handle critiques :3
