With the release of X and Y comes a new way of breeding. The way breeding works now is very different from how it has worked in previous generations. Old items have new uses and the mechanics themselves have changed. This post is to help explain those differences and hopefully to help breeders, new and old alike, to breed the perfect Pokemon.
Below is a list of new changes to how breeding works in Gen VI. If something is not mentioned here then it is still the same as in Gen V.
Perhaps one of the most important items in breeding now is Destiny Knot. What makes this item so special is, instead of 3 IVs from each parent being randomly chosen, when one of the parents is holding this item 5 IVs from both parents are passed on leaving only 1 IV to chance. With this item breeding Pokemon with 5 IVs is much much easier and faster then in previous generations.
Destiny Knot is given to you by a maid in the second floor of the Hotel Cyllage in Cyllage City. It is also given to you after you defeat Beauty Aimee who is in the alley where Cafe Cyclone is in Lumiose city.
With breeding in 6th Gen comes a nice surprise. Whatever the Pokeball the mother is in is now passed on to the offspring. For example, if you caught a female Eevee in a Premier Ball and bred with it all of its offspring will be hatched in Premier Balls. This only works for female Pokemon however. Genderless Pokemon and Dittos do not pass on their Pokeballs. Masterball and Cherish Balls will not be passed on even if the female is bred in one.
All Pokeballs can now be bought at one place. The Poke Ball Boutique in Lumiose City on Autumnal Avenue sells all the Pokeballs.
Unlike in Gen V where only females with their Hidden Abilities could pass on the ability when bred with a Pokemon in their egg group that was not a Ditto, males can now pass on their Hidden Abilities too, but only when bred with a Ditto. Males cannot pass on their Hidden Ability when bred with a female.
Pokemon caught in Friend Safaris can have their Hidden Abilities. Also Pokemon in Hordes can have Hidden Abilities.
Both males and females can pass on egg moves now making lots of egg move combinations that were illegal before possible to breed now.
So you've seen all these Pokemon that people have bred with 5 or even 6 31 IVs. If you would like to do the same for yourself, then this little guide is for you. Below is a step-by-step explanation for how to breed the perfect Pokemon that you've been wanting.
-Hatching O-power (not needed but recommended)
-Pokemon with Flame Body or Magma Armor
-Pokemon with Fly (preferably same as above to save spot in party for egg)
-Dittos with 2 to 3 IVs with 31
-Synchronizers to catch parents if needed
-Pokemon with Cute Charm with opposite gender of Pokemon you want
The first thing you need to do is acquire the items and Pokemon you'll be needing for breeding. An Everstone is given to you in Geosenge Town by a scientist in the building behind and to the left of the Pokecenter. Power Items can be bought for 16 BP a piece in the Battle Maison in Kiloude City. A Destiny Knot is a must if you're going for five 31 IVs. Having a Pokemon with Flame Body or Magma Armor halves the number of steps needed to hatch an egg, and using the Hatching Power O-power cuts down on the time needed to hatch an egg.
After you collect all the items you'll be needing, you'll need the parents you'll be using. If you're wanting a Hidden Ability make sure one of the parents has it. Having the female with the ability you want will speed up the process since the female's ability is passed on 80% of the time. If going for a certain Pokeball make sure the female was caught in the ball you want. Each parent has to have at least 1 31 IV each. Having one of the parents already with the nature you want will also speed up the process. You can use a Ditto as one of the parents to begin with so having Dittos with 31 IVs is helpful. All Pokemon caught in Friend Safari are guaranteed at least two IVs to be 31 so catching parents from there is recommended. Also chain breeding if necessary for the egg moves you want beforehand onto the parents is handy making sure to pass along any IVs that have 31 in them.
Make sure you know which parent has which IVs that are 31 and give one of them a Power Item that corresponds to the IV that is 31. Then give the Everstone to the other parent that has the nature you want. If neither parent has the nature you want, then you'll have to breed until you do or breed the nature on from another Pokemon. When you do get the nature you want then attach an Everstone to that parent. Keep breeding until you get a baby that has the nature you want and more IVs with 31 than one of the parents. Replace the parent and carry the Everstone over and change Power Item accordingly and repeat until each parent has at least four IVs with 31 a piece. When you do, replace the Power Item with the Destiny Knot and keep breeding until you get a baby with five 31's then replace the parents. Then keep breeding those until you get the exact Pokemon you wanted.
An example of what was explained above to make it simpler to follow.
Say you want a female Bold Eevee in a Premier Ball with the egg move Wish and IVs of 31/x/31/31/31/31. First you'll need parents, one with Wish and the female in a Premier Ball. Wish can be bred onto Eevee through Togepi by using Skitty as a breeding "bridge". So you breed Wish onto a male Eevee and it has one 31 in HP. Then you catch a female Bold Eevee in a Premier Ball and it has a 31 in Speed and Special Attack. You give the male Eevee a Power Weight and the Everstone to the female and breed until you get a male with 31 in HP and another 31 in another stat. Then you replace the male in the daycare with the male you got and make sure to give the Power Item to the Eevee you replace it with. Then you keep breeding until you get a male or female with 3 IVs that have 31. Replace parents and give the Destiny Knot to one of the parents and an Everstone to the other. Keep breeding for 4 31's and replace parents. Continue breeding for 5 31's, replace parents, and breed for the exact Pokemon you want.
Step by Step example:
Female Eevee Bold in Premier Ball x/x/x/31/x/31 holding Everstone + Male Eevee 31/x/x/x/x/x with Wish holding Power Weight
-Bred for a 31/x/x/31/x/x male
Female Eevee Bold in Premier Ball x/x/x/31/x/31 holding Everstone + Male Bold Eevee in Premier Ball 31/x/x/31/x/x with Wish holding Power Weight
-Bred for a 31/x/x/31/x/31 female. Needed Defense IV to have a 31 so switched parents.
Female Eevee Bold in Premier Ball 31/x/x/31/x/31 with Wish holding Everstone + Male Pokemon with a 31 in Defense holding Power Belt
-Bred for a 31/x/31/x/x/31 male
Female Eevee Bold in Premier Ball 31/x/x/31/x/31 with Wish holding Everstone + Male Bold Eevee in Premier Ball 31/x/31/x/x/31 with Wish holding Destiny Knot
-Bred for a 31/x/31/31/x/31 female
Female Eevee Bold in Premier Ball 31/x/31/31/x/31 with Wish holding Everstone + Male Pokemon with 31 in Special Defense and Speed holding Destiny Knot
-Bred for a 31/x/31/x/31/31 male
Female Eevee Bold in Premier Ball 31/x/31/31/x/31 with Wish holding Everstone + Male Bold Eevee in Premier Ball 31/x/31/x/31/31 with Wish holding Destiny Knot
-Bred for 31/x/31/31/31/31 male
Female Eevee Bold in Premier Ball 31/x/31/31/x/31 with Wish holding Everstone + Male Bold Eevee in Premier Ball 31/x/31/31/31/31 with Wish holding Destiny Knot
-Bred for a 31/x/31/31/31/31 female Eevee
It looks complicated and like it may take awhile, but compared to previous gens Gen VI IV breeding is much easier. Keep at it and eventually you'll get the Pokemon you desire. Good luck to you all and happy breeding!
