Gentlemen, I would like to propose a theory of 4 distinct Hex phenotypes, caused by dominant or recessive genotypes represented on the axes of the pictured chart. I will explain each classification as follows:
Official Hex is Hex as depicted in her media of origin, namely XY and Masters, and is thus an inoffensive design
Fanart Hex is Hex caused by the Moomoo Milk incident and the lasting effects it has had on her cultural zeitgeist. Plenty of SFW Hex fanart still depicts her as generously endowed, such as
>>56999590 for example.
Porn Hex is self-explanatory; it is how she is depicted in most pornographic material - well endowed and overtly sexual.
Tomoko Hex is perhaps the rarest and strangest phenotype - it is Hex in her onmodel design but overtly designed and displayed for sexual appeal. This is mainly for niche groups, such as people who enjoy weird stinky socially awkward NEET-esque girls such as Tomoko, thus explanining the name.
Thank you for attending my TED talk.
