Does Boo have a gender?

Gender Identity of Boo

Boo is unique among characters in the series for having transitioned genders at different points. Initially, Boo was portrayed as a male character until ILVGwebmaster decided to change this, aiming to introduce more female characters. According to ILVGwebmaster, the majority of Boos are considered female, particularly since, in Super Mario Galaxy, they express affection for Mario.
