In every Pokemon game where there are shiny Pokemon it is a matter of chance to come across a shiny Pokemon. They are EXTREMELY rare. They are easily identified because when they show up you see stars around them and they usually have different colors. I caught a shiny tentacool that had green spots instead of red. I also found a magcargo that was purple instead of red.
Catching these Pokemon is the same as other Pokemon. Battle it to lower its HP then throw a pokeball. If you make it faint you missed your chance.
Also note, if you have a shiny Pokemon, don't be afraid to let it evolve. My Tentacool evolved and kept it's shiny colors.
its completely random
Catch a shiny magikarp and evolve it.
The odds of running into a shiny Pokemon in Sapphire are 1 to 8192, there is no discovered way to catch a shiny Pokemon more easily... however if you trade Pokemon with a foreign Pokemon version i.e. American and Japanese, and then make an egg with that Pokemon, the chances of getting a shiny egg quadruple to 1 in 2048.
Here it is : 123456
You have a 1/8000 chances to see any shiny Pokemon find an area where you can find Aron alot and wait until its shiny then catch it.
You can get a Shiny Skitty in a 1 in 1800 chance that a shiny Pokemon will appear, let alone the odds of having a Skitty Swarm appear on route 116.
All you do is catch a ditto and a vullpixand put them in the day care and if your lucky the egg will hatch in to a shiny vullpix.
youcan not get shinys on Sapphire
What do you think... SHINY!!!!
How do you catch latios in Pokemon sapphire
There are many Pokemon you catch that are similar in sapphire and emerald but there are many Pokemon emerald can only get and not sapphire.
You can't catch a ditto in Pokemon Sapphire, but you can trade it from Pokemon Emerald/FireRed/LeafGreen.
