I just learned that piccolo’s species Namekians can reproduce asexually and technically have no genders, I have wondered for years why I never saw female namekians and wondered how they’d reproduce.
Apparently they just spit out eggs whenever they want.
“Though they might all have traits that could be associated with human males, the Namekians have no specific gender. They are often referred to as "he/him," but aside from that, they are considered to be genderless.”- CBR.Com.au
Google it guys it’s pretty interesting multiple sources cover the topic.
