Female for both. Pokemon X is my "serious" playthrough using my real name. Pokemon Y is my random challenges and fun playthrough using my pseudoname "Belldandy." I don't typically like playing as the other gender.
As always, for my first playthrough i picked the male character and named him after myself. This time it felt kind of special though, since the game allowed you to customize the protag as you wish!! Im currently replaying the game on another cartridge and chose the femalse protag, curious to find out the different customizations for her.
I usually play as female, but I bought both games this time so I was a girl in Y and was planning to do a blind Nuzlocke in X as a boy, but for some reason i can't remember I stopped with the Nuzlocke and only focused on my Y copy...
