This one contains some of what I would describe as possible issues as well. First two questions: Arenya's hair is blue, which is natural in her world for part dragons but not for normal people... uh, I'll call that unnatural in her world. She has wings and can fly which is an unusual power, but she can only fly for about a minute, and her other powers would be world-shattering on Earth, but within the context of the story are all attainable by regular humans simply by practice, no differently from you are I practicing weightlifting, and in fact she's much weaker and worse at them than most of her peers because they were wealthier and could afford tutors or went to better schools when younger. If it's no different from lifting weights, is it really a "power"? I ended up saying her powers were at "city-destroying" level, but that's more a vague metric of her ultimate potential than her current powers (where she'd probably beat an untrained person in hand-to-hand combat through sheer strength, lose to a trained fighter, and struggle to beat an average person who uses magic).
She doesn't have a "weakness", per se, but she also isn't a regular human, but would be vulnerable to, y'know, getting stabbed or equivalent.
I got 10% on this one for Arenya. Averaging across both quizzes I'm at 18.5%, which I think is a good metric for the sueness. As it stands, I maintain that quizzes like this can only be used as a general metric, not an infallible guide. We writers can certainly be blinded by our attraction to our characters, but at the same time we are the ones who know them and their stories best - so if we are confident that the results of such a quiz are wrong because there's details the quiz didn't take into account.
Curiously, I think Arenya's best friend would rank higher than her on this second quiz. No decidedly inhuman powers or tragic backstory, but she is very beautiful and has half the school falling for her. She is convinced that this is because her family is wealthy and everyone wants to get with her for the money, and she isn't wrong, but ignores that her appearance is a factor as well. However, she's so focused on her studies that she just rolls her eyes at the looks she gets, and deliberately dresses in non-attractive clothing to avoid getting attention. She's called the "blond ice queen" because she's cold to everyone who isn't as studious as her, but warms up to Arenya quickly for a couple reasons. She's a lot more skilled than Arenya and can learn topics very quickly... in fact, let me try the quiz with her in mind...
13%.
