Legendaries and Shines are very hard to find. But not impossible. In certain areas, where it says a Legend lives in, they can be found once you reach the end of the area, but that is very, very hard to do. In order to have a shiny or a Legendary appear is fairly simple.
[dice=50] No chance.
[dice=100] Close but not quite. 1.) Legendaries can not be caught if you don't have a Legendary Value of 1.
This means very simply that you must have a Legendary Value of 50 in order to catch a Legendary. Once you capture you, the value is placed back at 0. If you do not have a value of 50, you can witness the Pokemon in the wild, but not capture it.
2.) Legendaries can and will escape a Master Ball.
I know that it has a 100% success rate, but remember: Try to befriend the Pokemon before you capture it. If a Legendary is at 100 percent health, then you will simply not catch it if you throw a master ball unless you befriend it first and it ask to join your team.
Please note! You can meet a shiny or a legendary if it is on certain numbers. For a shiny: 48, 49, 50. For a Legend 99, 100.
Also, if the Legendary is part of a person's plot, but not a legendary that can be found in the area they are in, then make a mission for the Legendary to be obtained. As long as it is in their plot.[/center][rand=77684529738893693210007398312614359935863163813985792058400388579]
