If you're looking for the bizarro world crackhead bunny generator, it's on this page.
Select up to six characters for reassignment flippage. (Homunculi are set as neutral.)
This version does not weight the results; for the original version, see the Sex/Gender Designation System.
Note: the generator differentiates between sexual organs (sex parts) and reproductive organs (internal baby-making parts), because this allows for more variety, and because there are varying standards for "male/female/neutral", so it's left up to the author to determine which lines are drawn or defined where.
