My dragonsona, one of the main forms I use. Tai is bigender and regularly shifts between male and female presentations as well as anthro and feral. This is all done with their petrification and stone shaping abilities, becoming stone, reshaping, and becoming flesh again.
She/her or he/him are appropriate for their respective presentations when observed, but neither is default so they/them pronouns are used when referring to the character in general. Y'know... Schrodinger's Gender.
