Shiny legendaries are very rare. There is a very small chance of any of them being shiny, and if you battle one and see that they aren't shiny, the only way to get one is to start your game over (completely; erase existing data) and hope they are shiny next time.
The Shiny Suicune was a game stop event held before Pokemon black and whiter where releases. You had to get either suicune riakou or entei at the event of your Pokemon Pearl/diamond/platinum/soul silver/ or heart gold version, and then transfer them to your Pokemon black/white version.
This makes no sense, but you find a shiny in grass, as finding a shiny is 100% random.
Yes, you will be able to find a Shiny Kyurem.

You need: Starter lvl 88 Riakou/Entei lvl 59 6 revives I used Typhlosion and Riakou at those lvls. You are welcome.
You can find shiny Pokemon randomly through out the game.
You can find a Shiny Stone in route 6.
activate the shiny code with action replay and then activate the shaymin evant as well so you find a shiny shamin
To find a shiny stone in platinum you have to dig in the underground tunnel.
you can only find a shiny like 1 out of 1356.73
Trade it over from gold, or silver version.
