well for like the stationary legendaries all you'd really have to do to
get a shiny one is save right infront of it before you battle it
and then go into the battle and reset as many times as it takes 'til it pops up
shiny.
but for pokemon like Latios/Latias, Raikou, Entei, Suicune
the odds of actually getting it shiny are astronomical 'cuz even
finding them seems to take forever.
Odds are though that people that have those pokemon as shiny
juse used a cheat device to get them.
maybe not for the starters 'cuz you can breed them, and if you have
the patience to make 8K + eggs of any 1 pokemon just to get a shiny
well then more power to ya, I personally don't really care if it's shiny or not
a pokemon's a pokemon.
