Cross and Chris are two main characters I've got for that comic I've been threatening to make! Cross is a speedster, aspiring to be a professional hero, and Chris is his sister. And they're multiple, they share a body! Yyyyyeeeeeup.

So their body is female, Cross is male, so they hafta sorta manage/balance a or any transition between them--basically, they're currently on testosterone, and I believe they're either planning on getting or have gotten some sort of laser or electrolysis so they can't grow facial hair. They'll probably end up getting top surgery at some point, and probably not bottom surgery. They have no plans, desire, or need to integrate.
