Shiny Pokémon
Every Pokémon has an alternate coloration, commonly known as a shiny form. Every wild Pokémon you encounter has a 1 in 8,192 chance of being shiny. This does not mean, however, that every 8,192 Pokémon you find in the wild will be shiny, the chances are still the same. This is very rare to come across a shiny, and you never know when it will happen. A shiny will sparkle and make a “shine” noise when it comes into battle, so you know for sure it is a shiny. Also, when viewing a shiny Pokémon’s stats, it will have a star on the page. Shiny Pokémon were introduced in Gold and Silver Versions and were in every Pokémon game after those.
Shiny Pokémon are not any stronger that normal Pokémon. Trying to breed a shiny for a baby shiny will work, but still with the same 1 in 8,192 chance of getting one. This also applies to breeding normal Pokémon.
You should always carry at least a few Poké Balls and other types of Balls. If you run into a shiny and have no Poké Balls, you would be out of luck. Also, certain moves can make a shiny Pokémon end the battle, including Roar, Whirlwind, Selfdestruct, and Explosion. In the case of a wild Pokémon knowing any of these moves, use a Master Ball, and if you don’t have one, you better hope to catch it before it ends the battle. Another thing to note is that you should never attack a shiny Pokémon unless it is Super Fang or False Swipe. Catching Page
Red, Blue and Yellow
Since these games were for the original Game Boy, which was a monochromatic screen (black and white), there were no shiny Pokémon yet. You can, however catch a Pokémon and trade it to Gold, Silver or Crystal, and if you're lucky, it might be shiny.
Gold, Silver and Crystal
In Gold, Silver and Crystal, it was possible to breed a shiny with another non-shiny. If you did this, the chance would change to 1 in 64. This is because of the way stats were handled in these games.
Diamond, Pearl, Platinum, HeartGold and SoulSilver
A new addition to shiny Pokémon was put in these games. If you obtain a foreign Pokémon (one that's not in the same language as your Pokémon), you have an increased chance of getting a shiny Pokémon when breeding the foreign Pokémon with a non-foreign Pokémon. This is called the Masuda Method, and the chances then are rasied to 1 out of 2,048.
If you chain a long chain of Pokémon using the PokéRadar in Diamond, Pearl and Platinum, there is an increased chance of finding a shiny in the grass if the grass is shining as well.
Black and White
The Masuda Method is also in Black and White, but instead, the chances are 1 out of 1,366, meaning the chances are much more common.
Many people have caught or seen a shiny Pokémon, but some still have yet to encounter one.
I currently own a shiny Mime Jr. that I caught on Diamond and a shiny Rattata on HeartGold.

Happy shiny hunting!
