it is in cerulean cave
Mewtwo is in cerulean cave and tough to get
mewtwo
he is in a cerulean cave i beleive
you catch it in cerulean cave
You can't catch Mewtwo in Pokemon Diamond and pearl and also platinum. But you can catch Mewtwo in heartgold and soul silver
Probably either Mewtwo or Rayquaza.
You can find Mewtwo in the back of Cerulean Cave.
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.
yes you can after get your 16 g b in cerulean cave
well there isn't as far as i know.
just go to the cerulean city cave.
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.)
