I admit I'm kind of unsure of who to put here since I don't know what "non-human" entails. Does the character have to be completely non-humanoid or simply not be an earth, flesh and blood human? Any way, this is why you get two entries for this.
Naomi Armitage from Armitage III
Armitage is a third generation android, that can get pregnant. Unlike the other ones though she is also equipped to fight. And fight she does. I admit the whole hot pants and bra outfit is stupid, but it was the 90s, so there.
And if this doesn't count as non-human, we also have this one:
Fluttershy from My Little Pony: Friendship is Magic
Yes, I'm a fan of this show. I like Fluttershy the most because I can relate to being shy very well even if I'm not a big animal person. I like that she is the nicest and gentlest of the ponies, which is why I didn't like the newest episode that centered on her very much, because it seemed really out of character for her. All in all, season 2 just isn't as good as season 1 for me.
