Pokémon breeding

Breeding (Japanese: てる raise or やす increase) is the process of raising and hatching from s with the goal of obtaining a Pokémon with a particular trait. People who specialize in Pokémon breeding are known as s. Breeding (Japanese: える increase or reproduction) can also refer to the process through which Pokémon produce offspring and increase in population itself.
==In the core series games==
===How to breed===
In Generation II through Generation VI, two compatible Pokémon can breed when left at the Pokémon Day Care. In Generation VII and Generation VIII, this is instead done by leaving two compatible Pokémon at the Pokémon Nursery. In Generation IX, having a picnic with two or more compatible Pokémon allows for them to breed (regardless of whether the Pokémon are in the player's party or other players' Pokémon visiting via the Union Circle). Breeding is absent in Generation I, Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, and .
Two Pokémon are compatible if they share at least one Egg Group and are of opposite genders. As an exception, is compatible with almost all Pokémon regardless of gender (which is the only way for gender unknown Pokémon to breed). Pokémon in the Egg Group cannot breed in any way whatsoever, and Ditto also cannot breed with another Ditto.
In Generation II only, if the IVs of two Pokémon are the same and the IVs are either the same or differ by 8, they cannot produce Eggs. Because of how IVs are passed down from parents, this condition suggests the Pokémon are related.
====Locations====
Pokémon Day Cares and Pokémon Nurseries can be found in the following locations:

====Breeding rate====
The chance of any two Pokémon producing an Egg is determined by their species (two are the same species, while Bulbasaur and are not) and their Original Trainers. In Generation III or later, the Day-Care Man will describe the two Pokémon's compatibility when the player speaks to him. An Egg may be generated after every 256 steps the player takes.

The chances of finding an Egg are different in Generation II, and the compatibility can be checked by interacting with the Pokémon themselves instead of with the Day-Care Man.

====Receiving the Egg====
When there are two compatible Pokémon in the Day Care or Nursery, the game will periodically decide whether the NPC standing outside the facility has found an Egg, with the chances depending on the compatibility of the two Pokémon as detailed in the section above.
If an Egg was produced, the NPC will move from their default position so that the player can know they have an Egg.
*In Generation II, the Day-Care Man will appear in the Day Care's yard.
*In Generation III, the Day-Care Man will step out of line with the fence.
*In , the Day-Care Man will face the road instead of facing down.
*In , the Day-Care Man will face left or right instead of down and call the player over the Pokégear.
*In Generation V, the Day-Care Man will call out to the player when they are passing by on the road below, unless the player's party is full.
*In Generation VI, the Day-Care Man will face the road instead of in towards the Day Care.
*In Generation VII and Generation VIII, the Pokémon Nursery lady will fold her arms, with her right hand under her chin.
The NPC will hand the player an if the player replies that they want it. If the player replies they do not want the Egg, the NPC will permanently keep it. Prior to Generation VII, the player will only be given the Egg if they have an empty slot in their party for it to fill; if the player says they want the Egg but does not have a spare slot, the Day-Care Man will keep it until the player next speaks to him, at which point he will offer it again. In Generation VII and Generation VIII, the player no longer needs an empty slot in the party to accept an Egg, with any Eggs accepted with a full party being automatically sent to a Box.
In Generation IX, Eggs will appear during picnics in the basket in front of the picnic table while any two compatible Pokémon are in the picnic (including both the player's party and any other players' Pokémon also present via the Union Circle). When an Egg is collected from the basket, it is automatically sent to a Box. More than one Egg can be found in the basket at once.
====What will hatch====
After taking enough steps, the Egg will hatch into a level 5 (Generation II and ) or level 1 (Generation IV onward) first-stage Pokémon of the female species's (or non-Ditto parent's) evolutionary chain.

=====Gender-counterpart species=====
There are two pairs of Pokémon families where the male and female are different species. In these cases, an Egg produced has an even chance to hatch into either the male or female variant. The pairs are the following:

=====Incense breeding=====
Prior to Generation IX, there were several Pokémon which could produce two different kinds of Eggs, with a baby Pokémon being produced only if a parent of the Egg held a specific incense when it was produced. Starting in Generation IX, these Pokémon will always produce the baby Pokémon regardless of held item.

=====Regional forms=====
If a Pokémon has regional forms, then its offspring will always hatch into the form native to that region. However, if a parent of a foreign form is holding an Everstone and is from the same evolutionary line as the offspring, then the offspring will hatch into that parent's form.

===Hatching Eggs===
The time it takes for an Egg to hatch depends on its species's required number of Egg cycles. have the fewest Egg cycles, meaning they hatch the fastest. Some baby Pokémon in the , such as , , and , hatch quickly as well. Besides these, most Pokémon take considerable time to hatch. Rare and powerful Pokémon, like , , , , , and more, start with a high number of Egg cycles and take a long time to hatch. Most Legendary Pokémon have a very high number of Egg cycles, although it is impossible to get these Pokémon from an Egg in-game.
"Time" is actually determined by Egg cycle completion, which is determined by in-game steps or biking. An Egg cycle is a counted number of steps that activates breeding-related programs in the game. One Egg cycle lasts 256 steps in Generations and , 255 steps in Generation IV, 257 steps in Generations to , and 128 steps in later generations. When the game reaches the end of an Egg cycle, it does a few things: the step counter for the cycle is reset to zero, the game randomly decides if an Egg is to be found at the Day Care (if compatible Pokémon are present in the Day Care at the time), and all (or only a few) Eggs currently in the 's party have their Egg cycle count reduced by one. If the Egg cycle count for an Egg reaches zero after being reduced (in Generation II and from Generation V onward) or is zero when it would be reduced (in Generations III and IV), the Egg will begin to hatch. Prior to Generation V as well as Scarlet and Violet, if an Egg hatches, the game will not subtract an Egg cycle count from the rest of the Eggs after it in the party, ensuring that no two Eggs can hatch at the same time. From Generation V to VIII, if more than one Egg reaches zero at the same time, the first Egg hatches immediately while the rest hatch in order each time the player takes another step. In , each time the player is brought back to the overworld after hatching an Egg, the text box with the "Oh?" message will immediately appear which means that the rest of the Eggs hatch in order back to back.
In Generations III and IV, the Egg cycle's step counter can be reset by receiving an Egg from the Day-Care Man or the Manaphy Egg from the Mystery Gift delivery man in the Poké Mart. When an Egg is received from one of these people, the game resets the Egg cycle step counter to one in the third generation and to zero in the fourth generation.
As an example, in , a Egg starts with 25 Egg cycles, meaning it requires from 6,169 to 6,425 steps to hatch, depending on where the Egg cycle step counter is when the Egg is picked up. After each Egg cycle is completed, the Egg's Egg cycle count will drop by one, first to 24, then 23, then 22, and so on until the Egg cycle count hits zero, at which point the Egg will hatch into Misdreavus.
There are ways to speed up the time required to hatch an Egg. Riding a Bicycle reduces the time required simply by making it faster to complete steps. From onward, if a Pokémon with , , or is in a player's party, Egg cycles are reduced by two instead of one at the end of an Egg cycle, effectively halving the steps needed to hatch the Egg. In the Misdreavus example, the Egg would start at 25, and with in the party, the Egg would drop 2 Egg cycle counts after each Egg cycle, to 23 then 21 then 19 and so on, until it finally drops from 1 to 0 and hatches. Having multiple Pokémon with the Ability or one with each will not increase the Egg cycle reduction. Starting from Generation V, Hatching Powers can also be used (either from or O-Powers) to shorten the length of an Egg cycle, making Eggs hatch 1.25, 1.5, or 2× faster depending on the strength of the power used. In , Secret Pals in the player's Secret Base can also use the skill "Take care of an Egg" to reduce an Egg's Egg cycle count by half of its base Egg cycles.
===Passing moves down===
The moves obtained by a Pokémon when hatching are as follows:
* By default, the baby Pokémon will start with any moves that it learns at level 1. (In Generation II and Generation III, they will know all moves that are level 5 and below in their learnset.)
* If both parents know a move that the baby can learn via leveling up, the Pokémon will inherit that move.
* Prior to Generation VI, if the father knows any moves that are TMs or HMs in that game (and in , moves that are taught by a Move Tutor) that the baby is also compatible with, it will inherit the move. If a Pokémon species that is gender unknown (such as ) breeds with Ditto, the resultant baby will inherit any compatible TM or HM moves that the non-Ditto parent knows.
* If the father or, starting in Generation VI, the mother knows any specific Egg Moves that the baby can learn, the baby will inherit the move.
* From onward, if either parent is holding a Light Ball, a bred Pichu will know . Volt Tackle cannot be passed down as a normal Egg Move.
If this would result in the baby possessing more than four moves, the moves take priority in the order listed: Volt Tackle, mother's Egg Moves, father's Egg Moves, TM and HM moves, inherited level-up moves, baby's default moveset. The moves passed down will be ordered on the baby Pokémon by the priority listed above.
Starting in Generation VI, the Move Reminder can teach any Pokémon hatched in a Generation VI or later game any move that it knew when it hatched, if it has forgotten it. Moves that can be taught this way due to inheriting them appear at the top of the Move Reminder's list. However, even if a Pokémon meets the requirements for more than four inherited moves, only the moves it knew when it hatched can be taught by the Move Reminder.
Starting in Generation IX, a Pokémon with an empty move slot holding a Mirror Herb during a picnic can inherit compatible Egg Moves from other Pokémon in the picnic, regardless of Egg Groups, without the need for hatching a new Pokémon.
===Inheriting stats===
A Pokémon's individual values are also passed down. This is determined differently between generations.
====Generation II====
In Generation II games, the baby inherits its stats from the parent of the opposite gender, unless one parent is Ditto, in which case it inherits the stats from Ditto. The Defense DV (equivalent to IVs from Generation III onward) is passed, and also either the Special DV or the Special DV plus or minus 8 (plus for values in the 0-7 range; minus for values in the 8-15 range); the Special DV has a 50% chance of remaining the same. Attack and Speed DVs are determined entirely at random, whereas HP is determined by the DVs of the other four stats, using the same formula for wild Pokémon. The probability of a Pokémon having the same DVs as its opposite-gender parent is therefore 1/512.
If the Defense DVs of two partners are the same, and the Special DVs are either the same or differ by 8, the two Pokémon are incompatible. This is due to the high likelihood of a family relation, hence the inability to breed.
====Generation III====
In , , exactly three of the baby's IVs are inherited from its parents (e.g. if one parent contributes two IVs, its mate will contribute the third). The other three are determined at random, though it is possible that some of these may coincide with those of its parents without actually being inherited.
In , the process is similar but more complicated. First, a random IV is passed from one of the parents to the baby. Afterwards, a random IV of any stat (other than HP) is passed from either parent to the baby; if it is the same stat (not necessarily the same IV value, depending on whether or not the same parent passed it on), it will override it. Finally, another random IV of any stat other than HP and Defense is passed from one of the parents to the baby; this IV will override any of the previous two if it is from the same stat. The remaining stats (a number ranging from 3 to 5) are determined at random, again with the possibility of one or more IVs coinciding with those of the parents.
====Generation IV====
Inheriting IVs in and is determined in the same way as in .
From onward, the baby will inherit three IVs, each from a different stat and from a random parent. In addition, if either parent holds an Power item, the baby will instead receive the IV of the corresponding stat from that parent, then inherit two other random IVs each from a random parent; if both parents hold a Power item, the baby will inherit the corresponding stat to their held item from one of those parents at random. For example, if a parent is holding the Power Anklet, the baby will inherit the IV from that parent, and it will also inherit two other different IVs from its parents, such as Attack and Special Defense. As another example, if one parent holds a Power Anklet and the other parent holds a Power Weight, the baby will inherit either the Speed IV from the first parent or the HP IV from the second parent, and it will also inherit two different IVs from its parents other than Speed or HP (whichever was successfully inherited will be the one not chosen).
====Generation V====
Inheriting IVs in Generation V is determined in the same way as in .
====Generation VI====
From onward, if at least one parent holds a Destiny Knot, the baby will inherit five IVs instead of three.
This can be combined with a Power item to ensure that one desired IV is always inherited; however, the offspring will still inherit only a total of five IVs from its parents (the Power item simply guarantees which IV will be transferred for one of the five that the Destiny Knot allows).
===Inheriting Natures===
In , if the mother (in a male-female pair) or (in a pair that includes Ditto) is holding an Everstone, the baby has a 50% chance of inheriting that Pokémon's Nature.
In , inheriting Natures remains the same as in Emerald, except that passing on Natures via an Everstone will not work if the Pokémon have different original languages.
In , whichever Pokémon is holding an Everstone will have a chance of passing down its Nature, regardless of gender, or whether it is breeding with a Ditto.
In , inheriting Natures remains the same as in HeartGold and SoulSilver, except that passing on Natures via an Everstone will now work even if the Pokémon are from different original languages.
From onward, if one parent holds an Everstone, its Nature will always be passed down. If both parents are holding an Everstone, a parent's Nature will still always be passed down, but which parent's Nature is passed down is randomly determined.
From onward, if a Pokémon is given a mint, their stats will be changed, but the Nature used for breeding, and therefore the one that will be passed down with an Everstone, is unchanged.
===Inheriting Abilities===
In Generations and , Abilities could not be inherited by breeding—an Egg would simply randomly be born with one of its possible Abilities. From Generation V onward, parents have a chance to pass down their Ability slot in certain circumstances.
When breeding a female Pokémon with a male Pokémon, only the female Pokémon's Ability is relevant; when breeding a Pokémon with Ditto, only the non-Ditto Pokémon's Ability is relevant. If a parent's Ability is altered via Ability Patch or Ability Capsule, the new Ability slot is taken into account for breeding.
 with the Ability (which evolves into 's Dusk Form) is treated as a separate form, so breeding it uses form inheritance rather than Ability inheritance mechanics.
====Regular Abilities====
Pokémon with two possible non-Hidden Abilities have a different Ability in slots 1 and 2, while Pokémon with only one possible non-Hidden Ability have the same Ability in both slots.
In , if a female Pokémon is bred with a male Pokémon (but not when bred with Ditto), there is a 80% chance that its offspring will have the Ability in the same slot as the mother (regardless of whether it is a Hidden Ability or not). Pokémon bred with cannot pass their Abilities down. (In , non-Hidden Abilities cannot be passed down.)
For Generation VI onward, if the female Pokémon has a non-Hidden Ability, there is a 80% chance that its offspring will have the Ability in the same slot as the mother (regardless of whether it was bred with a male Pokémon or Ditto).
====Hidden Abilities====
In , if a female Pokémon has its Hidden Ability and is bred with a male Pokémon (but not when bred with Ditto), there is a 60% chance that its offspring will have its Hidden Ability; in , there is instead an 80% chance the offspring will have its Hidden Ability. (Male and gender-unknown Pokémon cannot pass their Ability down in these games.)
From Generation VI onward, if a female Pokémon, or any Pokémon bred with Ditto, has a Hidden Ability, there is a 60% chance that its offspring will have its Hidden Ability.
If an Egg does not inherit a Hidden Ability from a parent, it can only be born with a non-Hidden Ability.
===Inheriting forms===
In most cases, if a hatched species has multiple forms (not dependent on in-battle conditions), it will inherit the form of the mother or non- parent. will always hatch with the same cloak as its mother, and if bred between and Ditto, it will always hatch with a Plant Cloak. with the Ability , which evolves into 's Dusk Form, is treated as a separate form that is inherited by its offspring. , which changes its form using nectar, can also pass down its form by breeding.
There are a few exceptions to this inheritance pattern:
* will always hatch into its normal form, but this form can be changed afterwards.
* In Nintendo 3DS games, 's pattern depends on the set geographic area of the system at the time the save file it originated from was created, regardless of its parent's pattern. In Pokémon Scarlet and Violet, hatched will only evolve into Fancy Pattern Vivillon, regardless of its parent's pattern.
** The form that Scatterbug will evolve into is predetermined when the Egg is first obtained, not when hatched or evolved.
* , whose trims are temporary, will always hatch in its Natural Form.
* will always hatch in its Phony Form, regardless of its parent's form.
* will always hatch in its Counterfeit Form, regardless of its parent's form.
Species with regional forms will hatch into whichever form is native to the region they are bred in. However, if a parent of a foreign form and the same evolutionary line is holding an Everstone, the offspring will be of that parent's form instead. If both parents meet this criteria, the mother's form takes priority.
The Gigantamax Factor and the , Jumbo, and Mini marks cannot be passed down by breeding.
Pokémon such as , , and , where the species or form they will evolve into is predetermined when they are first generated, do not follow form inheritance rules. The forms or species of the parents have no influence on the personality value or encryption constant of the offspring.
===Inheriting Poké Balls===
From Generation II through , all Eggs are obtained in standard red-and-white s, regardless of the type of ball either parent was obtained in. In later generations, this is still used as the default ball if another type of ball is not inherited.

In Generation VI, the Poké Ball of the female Pokémon is always passed down to its offspring (even when bred with Ditto); male and gender-unknown Pokémon have no effect on their offspring's Poké Ball in this generation.

From Generation VII onward, usually offspring will have the same Poké Ball as the female Pokémon, or the non-Ditto Pokémon when breeding with Ditto. However, if a male and female Pokémon of the same species are bred (regardless of form), the offspring has an equal chance of inheriting either parent's Poké Ball.

===Breeding for Shininess===
====Generation II====
In Generation II, due to Shininess being determined by DVs (equivalent to IVs from Generation III onward) and the fact that DVs are passed down through breeding, it is possible for an Egg bred from a Shiny Pokémon to have a chance as high as 1/64 of being Shiny itself, but only if the offspring is of the opposite gender as the Shiny parent. This is not possible in any later generations due to Shininess no longer being related to DVs.
====Generation III====
In Generation III, a bred Pokémon always has the same chance of being Shiny as any Pokémon met in the wild.
====Generation IV====
Starting in Generation IV, if the two parents have different languages of origin, the Pokémon in Eggs they produce are more likely to be Shiny due to the Masuda method. The game does this by generating up to four additional personality values if the Pokémon is not Shiny, meaning that the Pokémon is approximately five times as likely to be Shiny (approximately 5/8192 or 1/1639).
====Generation V====
Starting in Generation V, the Masuda method now generates five additional personality values, meaning that the Pokémon is approximately six times as likely to be Shiny (approximately 6/8192 or 1/1366).
In , the Shiny Charm was introduced, which increases the player's chance of encountering or hatching Shiny Pokémon while in the player's Bag. If the player has the Shiny Charm when an Egg is generated, the game generates two additional personality values if the Pokémon is not Shiny, meaning that the Pokémon is approximately three times as likely to be Shiny (approximately 3/8192 or 1/2731).
The Shiny Charm and Masuda method can both apply at the same time. If they both do, their rerolls stack, resulting in seven additional personality values being generated, meaning that the Pokémon is approximately eight times as likely to be Shiny (approximately 8/8192 or 1/1024).
====Generation VI====
The overall Shiny rate has been increased to 1/4096. As a result, while the number of rerolls remains the same, the probability of hatching a Shiny Pokémon when using the Masuda method or Shiny Charm has also increased.
* The Masuda method alone generates five additional personality values (approximately 6/4096 or 1/683 chance of a Shiny Pokémon).
* The Shiny Charm alone generates two additional personality values (approximately 3/4096 or 1/1365 chance of a Shiny Pokémon).
* The Masuda method and Shiny Charm together generate up to seven additional personality values (approximately 8/4096 or 1/512 chance of a Shiny Pokémon).
====Generation VIII====
In Generation VIII, the Masuda method now generates six additional personality values, which would make it more likely to hatch a Shiny Pokémon; however, due to a bug, while breeding the original roll is skipped if any bonus rolls are applied. As a result, the Masuda method has the same probability of producing Shiny Pokémon as it does in Generation VII (both with and without the Shiny Charm); while the Shiny Charm alone actually has a lower chance of producing a Shiny Pokémon than it does in Generation VII or wild encounters do with the Shiny Charm alone.https://twitter.com/SciresM/status/1319799153162006530https://twitter.com/SciresM/status/1319805906691842050
* The Masuda method alone generates a total of six personality values (approximately 6/4096 or 1/683 chance of a Shiny Pokémon).
* The Shiny Charm alone generates a total of two personality values (approximately 2/4096 or 1/2048 chance of a Shiny Pokémon).
* The Masuda method and Shiny Charm together generate a total of eight personality values (approximately 8/4096 or 1/512 chance of a Shiny Pokémon).
====Generation IX====
The Pokémon Egg Shiny Roll bug from Generation VIII (which affects the effectiveness of the Shiny Charm while breeding) still applies.
The Sparkling Power provided by sandwiches does not affect the chances of an Egg being Shiny.

In , Pokémon breeding refers to an entire line of work practiced by s, such as and Reggie. Little has been shown and discussed about the literal breeding of to produce s, but it is assumed to be a part of a Breeder's work.
Pokémon breeding in animation focuses heavily on raising happy and healthy Pokémon and keeping them in top condition by them well and feeding them nutritious . When preparing Pokémon food, Breeders will carefully select ingredients to ensure that the Pokémon will consume all it needs to grow stronger and healthier.
Breeders are shown to have knowledge on how to treat Pokémon illnesses and injuries by administering Potions and other medicine. Some Breeders will use a to crush and grind herbs to produce herbal medicine. They also know which can be used to cure Pokémon from status conditions.
It has been shown that Pokémon Professors get their first partner Pokémon from Breeders who specifically raise and breed them, like Old Man Swamp from A Mudkip Mission. There are also a few farm-like facilities that produce Pokémon Eggs of various species. Both and have obtained Eggs from such locations.
In Following A Maiden's Voyage!, Johanna stated that would need to learn about breeding in order to become a Top Coordinator. This is because Pokémon Coordinators must care for their Pokémon's appearance and well being, something which requires them to know how to produce nutritious snacks in the form of Pokéblocks and Poffins, as well as to regularly groom them.

's special skill, as described by , is Pokémon hatching and is known as the "" ( Hatcher). He has the ability to draw out the largest potential of a baby Pokémon, having lived with Pokémon his whole life. Togebo and Pibu are testaments to that title, and share similar traits with him.
==Trivia==
* Except for Pokémon species in the group or with gender unknown, all other known Pokémon species can be indirectly or directly related to each other via their shared Egg Groups, even if no breeding with is involved.
* and cannot breed, despite the fact that the line and can. This is because Nidorina and Nidoqueen's inability to lay Eggs was established by Japanese media before breeding became a game mechanic.Pocket Monsters Encyclopedia: 「ニドラン♀の進化形だが、ニドリーナになると、卵を産む能力はなくなる。」 ("It is the evolved form of Nidoran♀, but upon becoming Nidorina, has lost the ability to lay Eggs.")ポケットモンスター公式ファンブック Official Fan Book of Pocket Monsters: 「ニドラン♀の進化形だが、卵は産めない。」 ("It is the evolved form of Nidoran♀, but it cannot lay Eggs.") As such, Nidoran♀ is the only Pokémon that loses the ability to breed upon evolving.
* Although all Legendary Pokémon, Mythical Pokémon, and Ultra Beasts except and cannot breed in the core series games, s containing , , and can be hatched in Pokémon Snap, and a baby appears in . Likewise, Manaphy can be hatched from a special Egg transferred from in the Generation IV games.
* When a Pokémon hatches from an Egg during both Generation II and Generation III, it is at level 5. However, many Pokémon from the wild can be found between levels 2 and 4, which is below the level of newly hatched Pokémon. This oddity has since been addressed from Generation IV onwards, where all hatched Pokémon start at level 1.
**An additional consequence of this is that level 1 Pokémon cannot be obtained legally until Generation IV.
* The Pokémon Mansion journals (which predate Generation II's introduction of breeding) describe Mew giving birth as opposed to producing an Egg. This was not changed in , but in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, the journal instead says "We obtained a new Pokémon from Mew." It is unclear as to whether this is meant literally or metaphorically.
