I assume you mean Unfezant, which can be male and female. It's one of the few Pokemon which shows clear Gender differences (the Female not having the long 'hair' on her head and having a brown stomach)
You can choose to be either a boy or a girl.
Marley.
Iris is the girl ash travels with, she is also the last gym leader in pokemon white
yes
Her name is Hilda in English or also known as White.
If you are referring to N from Pokemon Black and White, then yes he is a boy
actually there will be a new girl named Iris and a new boy and the series will be called pokemon black and white
dive is given to you by a girl in front of a house in undella town
In Nacrence city, in the building to the right of the Pokemon center. The girl with the petilil or cottonee will tell you how happy your Pokemon is.
Which girl are you talking about? If you are talking about your rival then you are wrong.You can't name her in white or black. In the English version her name is set to Bianca automatically.
After you defeat N and Ghetsis, go to Undella Town and a girl will give you the HM Dive.
There isn't any difference, only that one's a boy and the other one's a girl.
