Making a better, actually accurate one:

Elphaba Thropp, from "Wicked: The Life and Times of the Wicked Witch of the West" is canonically Intersex and Bisexual!
Elphaba, when she is born, is confused multiple times for a boy, before long minutes of debate from the make-shift midwives decide that she is a girl.
Multiple times she is described as being "not a boy, and not castrated" by both her mother and Nanny.
In her adult life when she is sleeping with her lover, she refuses to have sex with the lights turned on, does not allow anyone to see her naked below the waist, and has sex while forbidding her partner to touch her below the waist with his hands.
When her lover catches a glimpse of her naked under the moonlight when the blanket moved in her sleep, he spends a few long seconds in the darkness staring at a strange shape, a lump of some kind of scar at her groin, trying to figure out what he's looking at before she wakes up and sleepily covers herself with the blanket again.
One of the very first scenes in the book has The Lion, The Tin Man, and The Scarecrow gossiping about the Wicked Witch of the West, which include the following queerphobic lines:
*contains one instance of the H slur
"She was castrated at birth," replied the Tin Woodman calmly. "She was born hermaphroditic, or maybe entirely male."
"She's a woman who prefers the company of other women," said the Scarecrow.
"She's the spurned lover of a married man."
"She *is* a married man."
....Considering all of the above description of her physical form at birth and her statements, description, and behavior about sex as an adult, it is safe to say that she is indeed canonically intersex, even if the word itself is never used; the use of the h-slur above is canon enough.
While Elphaba does not canonically date or sleep with any woman in the book, she and Glinda share a bed on the way to the Emerald City, and she kisses Glinda before they seperate. Their feelings for each other are never really acknowledged in this unkind universe because this book is a tragedy, but in a kinder world, they might have acknowledged their feelings for each other and acted on them... And who knows where that would have led the future?
While speaking to her lover and talking about his arranged marriage and her dangerous line of work, he asks her about herself, and she replies "I am married, just not to a man" before bursting into tears, the implication being that her unnamed, unknown spouse had recently died.
