I recently read some Marvel comics called Runaways where one character is a shapeshifter who frequently shifts between male and female. When the youngest points out that it makes some people, uncomfortable, she has this to say:

What other non-binary characters have you seen around?
Bel Thorne in the Lois McMaster Bujold series about Miles Vorkosigan. It is a hermaphrodite who glories occasionally in freaking out people who are too wedded to the binary. :)
(It does, in fact, prefer the pronoun "it" and the label "hermaphrodite," and it's an alien species, so this is not technically something happening with humans either.)
Negative Man from Grant Morrison's Doom Patrol is a divine hermaphrodite named Rebis (the Hermetic term for the androgynous combination of male and female powers). Rebis is the combination of a man and a woman bound together by a energy being known as the Negative Spirit.
the maincharacter in orlando, is so far the only one I remember..
also im writting a comic for the moment and a couple of the characters is non binary,
I dont know if that counts.
There was a pretty hilarious exchange in Mass Effect 3 about asari and gender. They're humanoid blue aliens that seem to have female secondary sex characteristics, but they are mono-gendered and don't identify as female. They can reproduce with any gender of any species, and when two asari mate, only one of them gets pregnant and actually has the baby (the mother), and the other is known as the father. The exchange I mention is the main character (Commander Shepard) expressing confusion about the terms "father" and "mother", since he assumes that asari gender is equivalent to human female gender.
Note that there's a bit of (hilarious) profanity in the video:
