Once again, Is this not enough to convince you that she's female?

Seriously, Look at her! Just like a m,other she is taking care of all the children Pokemon! This is what being female is all about! Numelgon has a very mo,therly figure.

SHE EVEN PICKED ONE OF THEM UP WITH HER FEMININE, MO,THERLY PIGTAILS ANTENNAE

If that isn't feminine to you, then you mustn't know what femininity is at all. This is NOT masculine. It is blatantly feminine.

SHE EVEN THREW OFF SEVERAL FEMININE FACE EXPRESSIONS AND USED THE MOST FEMININE ATTACK IN POKEMON, DRAGON PULSE ONCE AGAIN

Yeah, gayfags. Concede now.

Japan isn't a fan of adding LGBT to kids cartoons. Ash's Numelgon is female.
