I was curious as to know in what Pokemon installments can I catch a shiny Pokemon and how. Can anyone tell me?
Shiny Pokemon have existed in the series since Generation II (Gold/Silver/Crystal). While Shiny Pokemon were originally based off of their IVs ("Individual Values") in Generation II, they are now merely a one in 8192 chance upon encounter to exist (determined at encounter-time). Methods exist to manipulate and determine the RNG seed of generation IV (Diamond/Pearl/Platinum) and V (Black/White/Black 2/White 2) games to help aid in hatching Shiny Pokemon from eggs, and the Poke Radar in Generation IV can be "chained" to increase the odds beyond their 1/8192 base.
They are, in the end, just a differently-colored Pokemon, however. You catch them the same way you do any other 'Mon - with a Pokeball (or better) and some luck.
Shiny Pokémon can be encountered in any core-series game from Gold and Silver onward. "Shinies" are Pokémon that have an alternate coloration from others in its species.
What is a Shiny
Whenever a Pokémon is generated by the game, there is a slight, fixed random chance that it will be shiny. This chance can be raised in certain circumstances; see the remaining sections.
Pokémon retain their shiny status through evolution and form changes. However, the exact coloration may be different (e.g., Shiny Charmander is yellow, Shiny Charizard is black).
Shiny Pokémon are indicated by a sparkling animation when they appear in battle, and a star or sparkle symbol on their status screen.
Each Pokémon form has precisely one alternate shiny coloration, and they differ only by color.
What is Not a Shiny
Shiny Pokémon are not to be confused with form differences or gender differences, which a handful of species have, and sometimes look very similar to shinies. Each form will have its own shiny variation, as well. For instance, Shellos has two forms, which differ both in color and head design.
Additionally, the N64 Stadium games will give slight alternate coloration to Pokémon with certain nicknames. These are not shinies, and in fact, Stadium 2 features both shinies (called "Color Pokémon") and these nickname-variations concurrently.
Finally, though all games have programming for shiny versions of all Pokémon, there are a few instances where a Pokémon will never be shiny, which are noted below.
Generation I - Red, Green, Blue, Yellow (Game Boy)
There is no direct support for shiny Pokémon in these games.
However, for compatibility reasons, the data that Generation II uses to determine shininess is also available in Generation I. Therefore, it could be said that Generation I does have Shinies, they just don't appear as such until they are traded forward. See the next section for why this is.
Generation II - Gold, Silver, Crystal (Game Boy Color)
The chance for wild encounters and NPC gifts being shiny is
To preserve backward compatibility with Generation I, this information is encoded in part of the Pokémon's hidden statistical information, called Individual Values (IVs). This means that Generation I Pokémon, when traded to Generation II, also have a
Pokémon hatched from eggs inherit IVs from their parents, meaning the chances can be skewed as high as
The Crystal-exclusive Odd Egg has an increased chance of producing a shiny:
Each game has a single Pokémon that is always shiny: a Gyarados in the middle of the Lake of Rage, encountered as part of the story.
Due to the way IVs are used for multiple things in these games, a few shinies are impossible:
Generation III - Ruby, Sapphire, Emerald, FireRed, LeafGreen (Game Boy Advance)
The chance for wild encounters, NPC gifts, and hatched eggs being shiny is
The data structure was overhauled in Ruby and Sapphire, separating battle statistics from shininess. The shiny calculation has thus been revamped, producing the same probability without being tied to gameplay-altering statistics.
Generation IV - Diamond, Pearl, Platinum, HeartGold, SoulSilver (DS)
The chance for wild encounters, NPC gifts, and hatched eggs being shiny is still
New is the so-called "Masuda method" (named after the developer who hinted at it to players): if two Pokémon are originally from two different real-world countries and can breed, the probability of their eggs producing shiny Pokémon is raised to
The post-game of Diamond, Pearl, and Platinum gives the player the Poké Radar item, which is used to create special shaking-grass encounters. Chaining these encounters together increases the probability that one of those grass patches will sparkle, guaranteeing a shiny encounter there. The probability rises as high as
As HeartGold and SoulSilver are remakes of Gold, Silver, and Crystal, they also have a fixed encounter with a shiny Gyarados. Unlike the original version, though, if you defeat it, it will reappear after you beat Lance.
Generation V - Black, White, Black 2, White 2 (DSi)
The chance for wild encounters, NPC gifts, and hatched eggs being shiny is once again
The Masuda method probability has risen to
In Black 2 and White 2 only, if you manage to catch all non-event Pokémon in the National Pokédex, you will receive the Shiny Charm, which automatically raises all shiny probabilities by
Black 2 and White 2 have two guaranteed shinies:
Three Pokémon are unable to be shiny:
Generation VI - X and Y (3DS)
The chance for wild encounters, NPC gifts, and hatched eggs being shiny has risen to
If you stand in the same spot and continually use a fishing rod, and get a hit every time, the rate apparently increases.
The Friend Safari, a post-game venue, has a higher chance of shiny encounters.
The following return from previous generations, but their exact rates are unknown:
Gen. | Base | Masuda| Extra | % | % | Chances --------|-------|-------|------- I (GB) | N/A | N/A | II (GBC)| .012 | N/A | = 100%: Story Gyarados = 14%: Odd Egg (C) III(GBA)| .012 | N/A | IV (DS) | .012 | .061 | = 0.5%: Radar (D/P/P) = 100%: Story Gyarados (HG/SS) V (DSi) | .012 | .073 | = 100%: Prize Gible (B2) = 100%: Prize Dratini (W2) = 100%: Prize Haxorus (B2/W2) + 0.024%: Shiny Charm (B2/W2) VI (3DS)| .024 | ??? | = ??%: Fishing = ??%: Friend Safari + ??%: Shiny Charm
* I'm unsure of the details on when Roaming Pokémon are generated. If anyone has additional information, please comment!
You can find shiny pokemon in generation 2 and onwards. The odds of encountering a shiny is 1/8192. It is unlikely that you will encounter a shiny, but it is possible.
They started appearing in Gold and Silver and have appeared in all games after.
They are randomly appearing pokemon (with some exceptions: red Gyrados in rage lake being one) and you catch them like any other wild pokemon.
