Legendary Breeding

[Lucidious89]

UPDATE!

This script is now compatible with Essentials v20.1 as part of my Legendary Breeding plugin. Refer to that plugin for the features found in this thread.

I've made a few changes that allows legendary species to breed. This is done by assigning genders to all the legendaries, as well as adding 8 new Egg Groups that are exclusive to legendary species. This keeps them special from regular species by separating them in their own groups, but still allows legendaries to have all the benefits of breeding. I'll be covering all current legendary species, but there shouldn't be any issues if your project doesn't include Pokemon from more recent gens.

First off, here are the new Egg Groups I've set up:

Skycrest
This group is primarily occupied by bird-like or winged species that dominate the skies.
Pokemon in this group:

Bestial
This group is primarily occupied by beast-like species that roam the lands. Most species in this group are quadrupeds.
Pokemon in this group:

, Calyrex

Titan
This is a small group made up primarily by large, hulking species.
Pokemon in this group:

Overlord
This is a small group made up primarily by Dragon-type species.
Pokemon in this group:

Nebulous
This group is primarily occupied by creatures with mysterious or cosmic origins. Most species in this group are bipedal, or align themselves vertically.
Pokemon in this group:

Enchanted
This group is primarily occupied by pixie-like species with strong ties to nature or other magical properties. Most species in this group are smaller-sized creatures.
Pokemon in this group:

, Calyrex

Ancestor
This group is occupied by the genetic ancestor to all other species. This group can breed with every other group in the game except for the Ditto and Ultra groups.
Pokemon in this group:

Ultra
This group is occupied only by Ultra beasts, or species with similar cosmic origins.
Pokemon in this group:

Special Cases
Some in-depth info on breeding mechanics for certain species.

Spoiler:

• 
  
  Ditto
  Ditto cannot breed with any species in any Legendary Egg Group. This includes both Mew and Ultra Beasts.
  
  
  
• 
  
  Mew
  Mew functions a lot like Ditto, but with extra functionality. Since Mew carries the DNA of all other species, it only makes sense that it can breed with most of them. Mew can breed with any of the normal egg groups (besides Ditto), and any of the Legendary Egg Groups (besides Ultra). When breeding with Mew, the egg species will always be that of Mew's partner (again, just like how Ditto functions). However, unlike Ditto, Mew can breed with itself to create more Mew. The one downside to breeding with Mew instead of Ditto is that Mew have genders. So gender-based compatibility rules still apply when breeding with Mew.
  
  
  
• 
  
  Mewtwo
  Mewtwo remains unchanged, and is incapable of breeding. As a mutated science experiment gone wrong, its genes are far too corrupted to breed with anything. However, you can still create Mewtwo eggs if two Mew are bred while either parent is holding a Berserk Gene. This will corrupt the offspring's DNA, creating a Mewtwo egg instead.
  
  Despite the unique breeding method, Mewtwo may still inherit Egg Moves from Mew.
  
  
  • Berserk Gene must be added to your items PBS file for this to work.
  
  
  
• 
  
  
  Regieleki, Regidrago
  Regis
  These species remain unchanged, and are incapable of breeding. They were not born through normal means, and were instead crafted by Regigigas out of natural resources. However, you can still create Regi eggs by breeding two Regigigas together while either parent is holding an item made of the appropriate material.
  
  Each Regi may inherit Egg Moves from Regigigas.
  
  
  • Regirock: Parent must be holding a Hard Stone.
  • Regice: Parent must be holding a Never-Melt Ice.
  • Registeel: Parent must be holding an Iron Ball.
  • Regieleki: Parent must be holding an Light Ball.
  • Regidrago: Parent must be holding an Dragon Fang.
  
  
  
• 
  
  
  Latias & Latios
  Latias has a 50% chance of producing either Latias or Latios eggs. Much like how female Nidoran can produce the male or female variants. The same thing occurs if Latios is bred with a female Mew.
  
  
  
• 
  
  Deoxys
  Deoxys eggs will inherit its mother's form when hatched (or father's form when bred with Mew).
  
  
  
• 
  
  
  
  Dialga, Palkia, Giratina
  These species remain unchanged, and are incapable of breeding. As beings that existed at the creation of the universe, their biology is beyond other species. However, you can still create eggs of these Pokemon by utilizing a unique mechanic with Arceus (more on this below).
  
  
  
• 
  
  Arceus
  Arceus remains unchanged, and is incapable of breeding. However, a unique mechanic exclusive to Arceus is implemented that allows it to spawn eggs through its own power, depending on the item its holding.
  
  Running the pbArceusEggSpawn script in an event will begin the egg spawn process. After selecting Arceus from your party, it will create an egg of one of the following species, depending on its held item:
  
  • Dialga: Creates an egg of this species when an Adamant Orb is held.
  • Palkia: Creates an egg of this species when a Lustrous Orb is held.
  • Giratina: Creates an egg of this species when a Griseous Orb is held.
  • Arceus: Creates an egg of this species when a Divine Plate is held. (Item needs to be added)
  • Type: Null: Creates an egg of this species when a False Plate is held. (Item needs to be added)
  
  
  
• 
  
  
  Phione & Manaphy
  As usual, breeding Manaphy will produce Phione eggs. But, if either parent is holding a Mystic Water, the parents will yield Manaphy eggs instead. However, Phione cannot produce Manaphy eggs in any way, and doesn't even appear in the same breeding group as Manaphy. Both Phione and Manaphy may inherit the same Egg Moves.
  
  
  
• 
  
  
  
  Tornadus, Thundurus, Landorus
  These species can only breed while in their Therian forms, as their biology matches other species the most while in these forms.
  
  
  
• 
  
  
  Zygarde
  Zygarde will always hatch in its 10% form when breeding (set as form 1). However, Zygarde 10% cannot breed, as it has too few cells to do so successfully. It must reach its 50% form before it's capable of breeding.
  
  
  
• 
  
  Type: Null
  This species remains unchanged, and is incapable of breeding. Much like Mewtwo, its genes have been corrupted too thoroughly through genetic experiment to breed. However, as described in the Arceus section, you can create Type: Null eggs if you use Arceus to spawn an egg while its holding a False Plate.
  
  
  
• 
  
  
  Solgaleo & Lunala
  These are unique in that they have different egg groups despite being of the same evolutionary family. Solgaleo is in the Bestial group, while Lunala is in the Skycrest group. However, both overlap in the Ultra group. These are the only species (along with Necrozma) that bridge the gap between Ultra Beast and non-Ultra Beast species.
  
  You may acquire Egg Moves onto Cosmog, but keep in mind that by default ive listed Solgaleo as a male-only species. So only Lunala will be able to inherit and pass down moves. This is because Mew cannot breed with these species (since they are in the Ultra group), so the only way to create a Cosmog egg is through Lunala.
  
  
  
• 
  
  
  
  
  
  NFE Legendaries
  These species remain unchanged, and are incapable of breeding. They're considered baby species, and thus are too immature to breed. Breed their evolved forms to obtain eggs of these species.
  
  
  
• 
  
  
  
  
  
  Fused Legendaries
  The fused forms of Kyurem (Black Kyurem, White Kyurem) and Necrozma (Dusk Mane, Dawn Wings, Ultra) cannot breed. You must revert them to their base forms before they can be bred.

this looks pretty cool


do we need to have up to gen7 pokemon/moves/abilities/items added or will it just ignore them if there not there?

It'll just ignore them if they aren't present.

thats good gives me time to sort that part out then

if i put a pokemon in a normal egg group and a legendary egg group would the normal egg group work as normal
the reason for this is because i am making a game with fakemon and one of them is ment to be 75% legendary (it has a baby form)

in this case i have Skycrest and Water 1. would it be able to breed with Poliwag and zapdos
Also manaphy already has 2 egg groups (Fairy and water 1) so enchanted would technically be a third

I haven't tested this possibility, but I would expect that you would be able to breed it with both Water 1 and Skycrest species. However Ditto would not be compatible with it (because Ditto will fail to breed with any legendary combo). Mew, however, should breed with it just fine.

good enough for me. i never understood how ditto can transform into a male of a female only species anyway or a female of a male only species
also you've missed Phione

I decided to keep Phione as it is. It was designed to be a bit weird in how it's obtained, and I'm ok with leaving it in the Water 1 group. I might add some kind of hold-item deal with Manaphy though, so that you can breed Manaphy eggs separately instead of always hatching Phione.

Minor Update 4/21/18
I've now added Egg Moves to every legendary species under my PBS File changes in my installation instructions. These Egg Moves are based on all of the species' Gen 7 learnsets. I tried to keep all Gen 6 & 7 moves at the end of each Pokemon's move list (if any), so you can easily delete them if your game is not up to date to include those new moves.

I've also made some small scripting changes to handle how Manaphy and Phione work, so you can now successfully create Manaphy eggs independently from Phione. When breeding Manaphy, the mother must hold a Mystic Water to create Manaphy eggs. Otherwise, only Phione will be hatched.

Please let me know if there are any errors or oversights I may need to correct.

sooo in my game is based on the zodiac (and im using the birthsign script) and i was wondering if the hatched pokemon can set based on its birthsign

Hmm what do you mean exactly? Are you asking if you could make the egg species change from what it would normally be based on what sign it inherits? I guess it depends on what you're trying to do, exactly. But I do suppose something like that would be possible, yes.

 

[p.claydon]

yh thats what i was meaning

 

[Lucidious89]

yh thats what i was meaning

Ok well, I tried playing around with it some. Unfortunately, I don't think there's any easy way to change the baby's species based on what sign it inherits...this is because Birthsigns are applied after the Pokemon hatches from the egg. While inside the egg, the Pokemon has no birthsign yet. So because of this, there isn't a way to really change the species beforehand without restructuring how the entire birthsign process works.

However, you can change the egg's species based on the parent's birthsigns.

So say for example, the mother species has the January sign, then you can code it so that the baby species it yields is different than it would normally be. You can even combine this with other factors, like what the current month is when the egg was created.

Here are some random examples I created:

Example 1

elsif isConst?(mother.species,PBSpecies,:PIKACHU)
    if mother.hasJanBirthsign?
      babyspecies=getConst(PBSpecies,:MARILL)
    elsif mother.hasFebBirthsign? && Time.now.mon==2
      babyspecies=getConst(PBSpecies,:PACHIRISU)
    elsif mother.hasMarBirthsign? && PBDayNight.isDay?
      babyspecies=getConst(PBSpecies,:EMOLGA)
    end

In this example, whenever you breed a mother Pikachu, the species it hatches will change depending on various factors.
1) If the mother has January's sign, it will always yield Marill eggs.
2) If the mother has the February sign, it will yield Pachirisu eggs if bred in the month of February.
3) If the mother has the March sign, it will yield Emolga eggs during the day.
4) In all other cases, the mother will yield Pichu eggs like normal.


Example 2

elsif isConst?(mother.species,PBSpecies,:MEOWTH)
    if mother.hasJanBirthsign? && father.hasDecBirthsign?
      babyspecies=getConst(PBSpecies,:SKITTY)
    elsif mother.hasPartnerSign?
      babyspecies=getConst(PBSpecies,:GLAMEOW)
    elsif mother.hasRivalSign?
      babyspecies=getConst(PBSpecies,:PURRLOIN)
    end

Here's some more examples using Meowth as the mother:
1) If the mother has the January sign, AND the father has the December sign, then the offspring species will be Skitty.
2) If the mother has one of the Partner signs of the current month, then the offspring will be Glameow.
3) If the mother has the Rival sign of the current month, then the offspring will be Purrloin.


Example 3

elsif isConst?(mother.species,PBSpecies,:MEW)
    if mother.hasCurrentSign? && father.hasCurrentSign?
      babyspecies=getConst(PBSpecies,:DITTO)
    end

In this case, if the mother species is Mew, and both parents share the same sign as the current month, then the offspring will hatch as Ditto.


Example 4

elsif isConst?(mother.item,PBItems,:JANZODICA) && mother.hasJanBirthsign?
    babyspecies=getConst(PBSpecies,:PIKACHU)

In this case, the offspring will be always be Pikachu for ANY parent species, as long as the mother has January's sign, and is holding a Janzodica stone.



Play around with it for yourself using these examples, and see what works. Hopefully you can get results that work with what you have in mind. You can enter this stuff in the breeding script under the "baby species" section, right below where I have all the code to determine Regigigas' offspring.

ah ok kool thank you

 

[Ulithium_Dragon]

I actually made an icon for the Berserk Gene a while back, since it never had one to begin with (as there were no item icons in Gens I and II).

If you want to include it, feel free:

*It's based loosely on the the DNA icon used for Mega Evolutions in Gens 6+.

EDIT: I also had a go at creating a False and Divine Plate just for funzies:

I don't need credit or anything, and you can do whatever you want with it.

Thanks for the contribution. I'll use these.

i have two other legendary's i a dark arceus and different type of lugia how can i add them

If they're just forms you added of those existing species, then you don't have to do anything, since they'll work in the same way as the base species does. If you added them as completely new species in your Pokemon PBS file, then you'd have to assign them genders/egg groups/egg moves that you deem appropriate.

ok thx for answering
