There is no such Pokemon as "Shadow" mewtwo. There is a regular mewtwo that you can catch like any other Pokemon. It's located in the Cerulean Caves.
In my opinion, it would probably have to be Mewtwo. I mean there might be harder things out there, but Mewtwo was the biggest challenge I had ever faced in Soul Silver. (NOTE: HEART GOLD AND SOUL SILVER IS BASICALLY THE SAME THINGS. THE ONLY DIFFERENCES ARE NAMES OF THE GAMES AND VERSION EXCLUSIVE POKEMON.)
sorry you have to trade it to Pokemon soul silver
You can't catch charizard in Pokemon soul silver. You can get a charmander from professor oak.
I am pretty sure this works the same way as other shiny Pokemon (approx. 1 out of a million chance.) I don't knnow for sure. However you do get to catch Mewtwo, i know because i did using only (surprisingly) 2 ultra balls(<sounds wrong<)
You can't catch Mewtwo in Pokemon Diamond and pearl and also platinum. But you can catch Mewtwo in heartgold and soul silver
