Don't even go there with the gender stereotypes. XD I'm female and I immediately preferred Yveltal, if only for the design. Though X and Y are likely referring to chromosomes, I also think it's a double-play on the dimensional axes, XYZ. Clever, given that this is the Pokemon franchise's first 3D main adventure. It's highly likely that sometime down the line, we'll get a third installment titled "Pokemon Z."
