You do realize that she's female right? The voice actor is a dude, but that proves nothing. They wouldn't have something this fucking feminine in the anime as a male. Also you take into account that nobody unironically likes male ones. No, She's more feminine than Gardevoir, so don't bring up others mons like Purrloin as an excuse.

She doesn't sound female, but this again is more evidence proving that she is. How so? Leavanny was a dude and it sounded blatantly female. Numelgon is essentially this in reverse.
