Doesn't Landorus have a gender? Which only makes the genderless legendary thing even weirder.

I think it's also weird that you can't breed two Dittos to get a Ditto, while they can breed with just about everything else. What's up with that?

There is an official explanation for the absence of Berry Pots in B/W: the land in Unova is not suitable for growing berries. I think they just did it to get people to use the Dream World.
