Well........... To get a shiny mewtwo you have to got to the cave where it is in then if you battle it get it's health low as possible with the false swipe Tm.
Then wait a couple of hours with the DS OPEN not CLOSED then when you come back it will be shiny (green colour).
This might work i heard it's 3/10 that it will work so 30%.
Hope this helped!
You can't,but you can get mewtwo!
you dont, its not in HeartGold or SoulSilver, Ho-oh (HeartGold) or Lugia (SoulSilver) take their place. You can also get mewtwo
It is very hard to get Mewtwo. By the time you read this, it probably would of finished, but there is/was a Mewtwo event on for Pokemon Black and White gamers. If you have Soulsilver/Heartgold, if you have finished the game, (got all 16 badges etc) in a cave in the second region, there is a Mewtwo really deep down. I got 2 Mewtwos, one from Soulsilver, (LV82) and one event one (LV72). Hope this helps!
