Talk:Azurill

Untitled

AZURILL (Pokémon Ruby & Sapphire): This is the unevolved form of Gold-&-Silver-onward Pokémon, Marill (the former very popular 'Aqua Mouse' or 'pikablu'). Its infancy is apparent, as its body has not 'grown into' the proper scale for its gargantuan tail. The baloon-like tail - according to the Pokédex - is filled with oil, allowing Azuill to float on the surface and always have a nice relaxing time when swiming. It's only an ickle mouse, really.

Changing gender

It is also the ''only'' Pokémon whose gender
 ratio is different than its evolved
 form—probably a mistake on the
 part of the game's designers—and
 due to the way Pokémon genders are
 determined, this means that 1 in every
 3 female Azurills change to male when
 they evolve.

Yes, I know someone is going to call me out on this (it hasn't been reverted yet AFAIK, but it's undoubtedly gonna happen), but it does happen. Check the gender ratios on serebii.net—they do agree with this—and try it in the games (mind, it's only 1 in 3 female Azurills, and it never happens to males.) --HeroicJay

I find it very hard to believe that a Pokémon will change genders when it evolves. If you capture Marril in the wild, then half will be male, and half will be female. But when specifically breeding, the baby Azurill will have the seperate gender ratio. Sonic Mew 19:10, Jun 23, 2005 (UTC)

Maybe you find it hard to believe, but it DOES happen. Feel free to test it. (You need multiple distinct female Azurills to test - five or so should probably do it, but you can have a few extras to be safe. At 5, the chances you have such an Azurill are abouit 83% by my calculations, and at 10, 98%. Using the same Azurill by saving right before it evolves will NOT work - if it's female after evolution once, it will be the next time too.) Let me explain. When a Pokemon is born, met, or whatever, the game does not flip a coin to see if it is male or female. Rather, it assigns a random number between 0 and 255 as the Gender Value (henceforth, GV). The GV of an individual Pokemon never changes, nor should it. Each Pokemon species has a threshhold for their gender values. I might have the male and female swapped, but the way it works is that, if the threshhold is 255, the Pokemon is automatically genderless. If it's 254, the Pokemon is automatically male. If it's 0, it's automatically female. Otherwise, if the GV is below or equal to the threshhold, it's male, and if it's above, it's female (again, I could have male and female swapped here.) The deal is, Azurill and Marill have different threshholds. They almost certainly shouldn't, but they do. Since the GV doesn't change when it evolves, if its GV falls between the two different threshholds, it'll swap from female to male. This does happen. I have personally seen it with my own eyes, talked with others online who have seen it, and it's a really easy test (the hardest part is evolving the blasted things - they're happiness evolvers.) I know it doesn't make sense. That's why I specifically said it was probably a mistake on the part of the game's designers. But I'm just the reporter. Also, probably the only reason this isn't as well-known as it should be is because... who really uses Azurills anyway? I had no idea that the gender ratios were different until it was explicitly pointed out to me, and I still had to see it with my own eyes before believing it. Go ahead! Test it! Be my guest! Complain, I will not! --HeroicJay 28 June 2005 07:37 (UTC)
