It seems like the breeding mechanics for Pokémon Black and White 2 have changed from the normal breeding. The new system now allows you to easily give your Pokémon a nature that will normally take you quite some time to get.
- Each Pokémon has a single pre-designated ability
- There’s no way of changing what this is
- Some Pokémon are capable of having one of two pre-designated abilities
- The ability is chosen at random when you encounter the Pokémon in the wild
- During breeding, the baby Pokémon’s ability is now dependent on its mother
- If the mother is a dual-ability type, the baby has an 80% chance of inheriting that ability
- This gives the baby a 20% chance of inheriting the other ability that the mother doesn’t have
- You can now 100% guarantee that your Pokémon will inherit a nature from one of its parents
- To do this, give one of the parents an Everstone to hold
