Already knew what was in the game 'cuz leaks so didn't really give a crap.
>>56088657First off, gender unknown is not genderless, it means no-one's sure if it has a winky or hoo-haa. Secondly, the franchise itself canonised male and female Mewtwo when they wrote an entirely new, female, Mewtwo to appear in Genesect's movie. That GAme Freak also gave it a Masculine and Feminine Mega form just shows they see it as being either gender on top.
Shudo wrote ONE specific Mewtwo, not created the entire fucking concept of the thing..
