RWBY's Fairytale inspirations are honestly pretty useless in terms of helping a character analysis.
There's no real consistency in how the inspiration plays into the character, except maybe the Wizard of Oz ones, and few of them actually tell you anything about the characters.
How does knowing Ruby is Little Red Riding Hood affect your understanding of her character, or where it's going to go? Or Salem being the Wicked Witch? Hell some aren't even fairytales at all, Coco's a fashion designer Nazi, Neon and the rest of FNKI are memes/in-jokes, and I don't think Sherlock Holmes is a fairytale.
This is why I don't really get why people keep trying to find Neo's allusion, they seldomly matter beyond fueling fan theories.
For a setting that emphasizes fairytales and stories, they really aren't that important in the grand scheme of the plot or setting.
