Look, I know this is the third idea I've discussed that has previously been done by another user, just leave me alone!
Okay, who honestly thinks that Pikachu is a female? Seriously. There have only been about four arguments to support that he's a female, and they don't work. First, Pikachu wearing one of Misty's dresses. Second, Buneary is either a lesbian or doesn't know Pikachu's gender but likes him anyway. Third, Chikorita's rivalry for Ash's affections with Pikachu. Fourth, the lack of a groove in the tail is because this was before the gender differences. You see what I mean?
Have you seen two girl animals mating and actually making it work? Of course not. This one's a guy.
Just so you know, if there's not enough mannerisms, I go with gut instinct. Here, I kinda think Pidgeotto/Pidgeot is a female.
All of Ash's Kanto starters seemed to have male personalities, and this one had the hots for a Gloom. Sure, the Gloom could have been male, but I say it was a female. Again, I state my thought that some animals don't have capacity or care for homosexuality.
Of course it's a male! It had the hots for a clearly female Charizard named Charla! Relating to my point about some animals and homoexuality, Charizard must be a guy.
Seemed all manly as the leader of the Squirtle Squad, so I say it's a guy.
Okay, my instincts fail me this time, I HAVE NO FRIGGIN' IDEA!
A wild male baboon? That makes sense!
…well DUH! You ought to be an idiot to not think these are male (unless you haven't done enough research).
Likes to get on men, but it's probably a clingy male, like Brock's Sudowoodo! However, it has shown affection for Jessie, so it must be a clingy male.
My instincts tell me it's a girl.
Gut instinct. I don't really rely on game mechanics, just instinct.
Again, gut instinct. However, this could be subject to change if it is seen later with a gender difference edit.
She has the hots for Ash, and possibly his Sceptile.
Meh, seems like one.
This one had affections for two Pokémon that were clearly female, an Azumarill with a bow in it's tail and a Quagsire with a bow in it's head. Plus, it has that goofy and energetic personality that only males can have.
Like Kingler, my instincts fail to see some truth.
Seemed a little strong and manly as a Phanpy, and got macho as a Donphan.
