you have to get 16 badges and go to the end of the cerulean cave and mewtwo will be waiting there
he is at level 70
Try the Timer Ball.
You can catch MEWTWO ,not Mewto, at the end of Cerulean cave
you cant catch mewtwo in Pokemon platinum peral diamond you can in Pokemon heart gold and solsilver in canalave cave
U can't in heart gold but u can catch mewtwo
Mew can't be catched in Pokemon heartgold, only mewtwo.
That's just an fan-made sprite. It doesn't really exist in the real games.
Curlean Cave, go very deep inside the cave ,then go back to the entrance, and Mewtwo will be standing there,make sure you have all 16 bagdes though
Just defeat the elite 4 again and he will return.Hope it works.
you finish the game with heart gold then you go to kanto and you defeat gyms and on the way you'll get zapdos moltres mew mewtwo an so on
Yes, Mewtwo will reappear once you have defeated it however you must defeat Lance, the Champion after defeating Mewtwo in order to regenerate it.
You can't catch Mewtwo in Gold, Silver, or Crystal. But you can catch it in HeartGold and SoulSilver in the Cerulean Cave at Lv70.
