Talk:Egg Group

Active discussions

Technically a lot of Pokemon listed as "No Eggs" on here aren't in that group. For example, Solrock is in the Mineral group. The reason it can't breed with other Pokemon in that group is because it doesn't have a gender. Ditto can breed with genderless Pokemon who are not in the No Eggs and Ditto groups, including Pokemon like the genderless Solrock in the Mineral group. So, should this page be rewritten with a note somewhere about genderless Pokemon in various groups? --Meowth346

Yeah, probably should. --Ketsuban

Solarock isn't in the Mineral group. All groups are accurate. I used the Nintendo Power Pokemon Ruby and Sapphire guide. All groups are accurate. I am not rewriting this page, Meowth. If you want, you can add a thing about Ditto able to breed with certain genderless pokemon and list who they are. LedianX 01:47, 11 Mar 2005 (UTC)

If the game's ROM clearly indicates a different reality than the official Nintendo guide, I vote for mentioning both somehow, perhaps an asterisk to an explanatory note of some type. Reason being, if its in an official company document, it could very well end up that way when the next generation is implemented, especially if the source code is not recycled.

I know we talked for a moment on IM about this, but I'll add it here as well: the game's internal data which is used to decide if two Pokemon can breed, it lists Solrock as being in the Mineral group, etc. The only reason it cannot breed with other Pokemon in this groups is because it doesn't have a gender. If you could modify the game's data to give Solrock a gender, it would breed with Pokemon in the Mineral group. Pokemon in the No Eggs group cannot breed with anything, no matter what. That said, I could easily re-write the page to sort the Pokemon into their correct egg groups, with a note about genderless Pokemon. But I must say, Nintendo of America's player guides cannot be taken more seriously than the game's internal data/assembly which determines what egg group each species is in and which Pokemon can breed with which. --Meowth346

Changed it so they're listed. I hope it is satisfactory.LedianX 02:11, 11 Mar 2005 (UTC)

Not really a quibble, since I know it's true, but has it ever been explained *why* Nidorina and Nidoqueen can't breed? (Y'know, outside MR, that is, with the Nidoqueen apparently breeding with the Ryhorn)--BJ

What's with all of these span id tags? Whoever's making them, they're putting them in wrong and it's showing up on the page. I'm not going to delete them, just in case they're important. →Evin290 15:20, 11 July 2006 (UTC)

Just occured to me - why is it that this article's first two paragraphs of content are about breeding in general and not really related to egg groups? I think I'm gonna rewrite that... --Pie 06:26, 1 December 2006 (UTC)

Ironically, Meowth isn't on the list. What's the ordering, anyway? Are we allowed to use info from, say, Serebii? --Raijinili 07:51, 22 January 2007 (UTC)

In all honesty, I don't see much rhyme or reason to their ordering in the list, except that related Pokémon are near each other. Meaning, don't put Persian on top and Meowth on the bottom. Just put them under the right group. And... well, if Serebii's in the link section of the Pokémon infobox, then go right the heck ahead. Just crosscheck everything you find at any site across to the others. Make sure we get the right info. Tom Temprotran 11:21, 22 January 2007 (UTC)

I've seen the same names for the egg groups used on many publications and websites -- is there any "officialness" to them, or are they just the tags people have used since gen2 and they've stuck? Should this be mentioned? ~~

They've been official. Stadium 2, Earl's Academy names them as such. I'd not doubt that in-game data structures name them as the same. --TTEchidna 03:06, 3 May 2007 (UTC)

Here's a question: The chansey page and this page seem to be in conflict with each other. The chansey page says it is in the fairy egg group, but this page lists it as a humanshape egg group. Which is correct? Which should be brought into harmony with the other? Talonos

Should a description be provided for every egg group describing what each of the pokémon within that group have in common? PDL

Gen II

I remember hearing once that the ugly little menu sprites of Generation II allowed you to see the egg group of a Pokémon. Does anyone know anything about this?--MisterE13 02:29, 6 November 2008 (UTC)

No, it really didn't have much of a bearing. TTEchidna 03:54, 6 November 2008 (UTC)

Trivia: Egg Groups Graph

More trivia than anything else, and also a need to know if it's been done already before doing. Let's start the explanation, it's quite verbose...

Say you make a directed graph, in which each Pokémon species is a node. Pokémon A is connected to Pokémon B if, and only if, A can produce eggs of B as the "father". That would mean, for instance, that every Pokémon would have an edge pointing from Ditto, but Ditto would have no edge pointing to itself. Every dual-gendered Pokémon would have an edge pointing to itself, and edges pointing to a Pokémon in its egg group and back (if the other Pokémon is dual-gendered, that is). Tauros would have an edge pointing to Miltank, but not back, and so on...

With that in mind, it means that, if you can make a path from A to B, it means you can pass TM moves from A to B, following that path of breeding. E.g., there would be a path from Charmander to Ekans , and from Ekans to Sneasel, indicating you can chain breed moves from Sneasel to Ekans. Nonetheless, this part of the explanation serves only the purpose of showing this have at least some practical value, meaning it may have even be made before.

So, if you haven't followed the explanation through here, we have a big diagram with every Pokémon that can breed (excluding, though, the No Eggs group) connected to each other. The resulting diagram would be clearly separated into "clusters" composed of single grouped Pokémon, with double grouped Pokémon in-between, and genderless Pokémon and Ditto on another. Now, the trivia question I planned on doing after all this explanation is: is it possible to breed any Pokémon in each group to any Pokémon in any other group, via chain breeding or not, excluding genderless, Ditto and No Eggs Pokémon?

That's it. I just wanted to know if it has been already done... -- Professional Mole (Talk here) 14:44, 29 December 2008 (UTC)

Done it! I didn't use a graph though, I just lined up thirteen tabs in Firefox... So here's an example:
  1. Water 2 - Gyarados/Magikarp
  2. Dragon - Swablu/Altaria
  3. Flying - Farfetch'd
  4. Ground - Nidoran lines, Ryhorn line, Whismur line
  5. Monster - Gen I,II,IV grass starters, Snover line, Tropius
  6. Plant - Cacnea/Cacturne
  7. Humanshape - Volbeat/Illumise
  8. Bug - Skorupi/Drapion
  9. Water 3 - Gen I fossils, Corsola, Crawdaunt line
  10. Water 1 - Shellos line
  11. Indeterminate - Castform
  12. Fairy - Snorunt line
  13. hence Mineral
I think it will probably be necessary to breed within some egg groups in order to get to the end of this, but maybe not. I have rather cleverly confused myself, so I hope anyone reading this can follow :D — THE TROM — 07:49, 30 December 2008 (UTC)
Hm,'kay that's basically what I wanted to know, indeed. So, that means you can breed any egg group with another egg group. Impressive. -- Professional Mole (Talk here) 15:13, 30 December 2008 (UTC)


Personally I would find it useful if, in the individual egg group pages, there was a portion of the table that listed gender percentages. The most useful application would be in the mineral group to identify which species are genderless at a glance. Secondly, to identify species which have no females/males. I feel this change would only enhance the pages as references for breeding. I'm not asking for someone else to do it, I'm asking if (and how) it should be done. Githe 13:35, 1 October 2009 (UTC)

Ingame or fanbased?

Are the names of egg groups found inside the game or have they been made up by fans just to reference the different groups? Chum 22:42, 10 December 2010 (UTC)

Neither, they're found in official guides or something like that...Ataro 22:43, 10 December 2010 (UTC)
They're in a Pokémon Stadium but I don't know which one. If we were to use guides, we would have to rename the Ground Egg Group to Field due to the HGSS guide (as well as a few other changes to names I think). --SnorlaxMonster 11:22, 26 December 2010 (UTC)
They're named such in Pokémon Stadium 2. Frugali 10:51, 31 December 2010 (UTC)

Pokédex 3D

The new Pokédex 3D app has new names for all the egg groups. Ground is now Field, Plant is now Grass, No Eggs is Undiscovered, Fairy, Monster and Dragon remain the same and I don't have any Pokémon in any of the other groups yet. Given the amount of edits it would take, I'm asking here first. Is it OK for these Egg groups to be moved? Blazios 08:57, 7 June 2011 (UTC)

In the official Platinum strategy guide, the egg groups are named Grass group, Bug Group, Flying Group, Human-like group, Monster Group, Fairy Group, Dragon Group, Mineral Group, Field group, Amorphous group, Water group 1, Water group 2, Water group 3, Ditto Group, No Eggs found group. --SnorlaxMonster 09:18, 7 June 2011 (UTC)
Surely an actual game is of more significance than a strategy guide, even an official one? Even if they are the same, the Pokédex names are the most recent. Blazios 09:23, 7 June 2011 (UTC)
I was pointing out the fact that these names are not new (apart from No Eggs being Undiscovered). It means that these names have almost certainly been retconned, and have been for some time. I'm leaning more towards using the new names over the old names. --SnorlaxMonster 09:27, 7 June 2011 (UTC)
I was just about to bring this up myself. The old source, Pokemon Stadium 2, is now over ten years old, and a lot about the game has changed since then. It's possible Nintendo was using these names even as early as Ruby and Sapphire and we just never knew. We now have an official source for the egg group names... the only question, I think, would probably be whether to start renaming now, or to wait until the application updates to show at least one Pokemon from each egg group so we have the official names of all of them at once. -- Saethori 06:49, 8 June 2011 (UTC)
We have all the official names from the Search option. They're all the same as the ones SnorlaxMonster posted, except No Eggs is Undiscovered. Blazios 07:06, 8 June 2011 (UTC)
My question is, are the water groups formatted like mine were? So "Water group 1" etc., rather than our current "Water 1 group" etc.? --SnorlaxMonster 07:21, 8 June 2011 (UTC)
It's the latter, they're just Water 1, Water 2 and Water 3. Blazios 07:36, 8 June 2011 (UTC)
Oh, so it omits "group" entirely? Interesting... --SnorlaxMonster 07:56, 8 June 2011 (UTC)
Never has mentioned "group", it's the same sort of disambiguation that happens for types. After all, Starmie in the game has two icons, which say WATER and PSYCHC. It's a dual-type Water/Psychic Pokémon.
Either way, pics of the strategy guide or it didn't happen. TTEchidna 07:30, 9 June 2011 (UTC)
They were a bit hard to scan due to how ridiculously thick the guide is, but it really should only affect things on the inside edge. [1] [2] [3] [4] [5].
Anyway, since we are moving them anyway, we should really capitalize "Egg", since it is always capitalized. Also, I think the number from the Water groups goes after "group" as a standard, as it is used here too. --SnorlaxMonster 10:52, 9 June 2011 (UTC)

Japanese names

Have the Japanese names always been the same for each egg group or have they changed inbetween Stadium 2 and Pokédex 3D? --Abcboy (talk) 10:45, 26 July 2012 (UTC)

Regional Variant formatting

Is there a way to fix the formatting for how regional variants, Ash-Greninja and other alternate forms are represented on the various egg group pages? They all have their Pokédex numbers listed as "105A" (Alolan Marowak) or "745Mn" (Midnight Lycanroc). What's the coding involved in making the various Wormadam forms visible without these issues?
