Okay beat the elite four at least once, get the national dex and make sure you deliver the ruby and sapphire to celio in the one island Pokemon center, if you did all this theres one more thing, on four island theres a house to the right of the pokemart go in and talk to the guy inside he will give you a sticker for your victory in the elite four. Now go to cerulean city and notice theres a cave in the northwest but you need surf to get there use surf and enter cerulean cave. Caution! Danger lurks in this cave because level 50's and 60's Pokemon will attack you! If you manage to make it to the end of the cave you will find mewtwo. CAUTION! Save your game for one and second its level 70! Do your best to catch it.
you can catch mewtwo in cerulean cave in cerulean city but first you have to beat the elite four
No you can catch him afterwards but it helps to beat the elite four
explore around and catch mewtwo.
just beat the elite four
you must beat the elite 4 twelve times go to where you caught mewtwo and catch mew :)
Nothing.
you go and beat the elite four with him. i beat the elite four easy with my party. -------------------- Mewtwo Lv70 CharizardLv77 Vaporeon Lv65 Haunter Lv54 Weepinbell Lv47 Lapras Lv70 --------------------
Beat the Elite 4 then yhe guy will move and you will be able to catch mewtwo
First you have to beat the elite 4 12 times, then go to cerulan cave, and go by the place were you catch mewtwo, then if he is not visible, just run around the place until he is. ( This only works if you have caught or defeated mewtwo)
first u have to beat the elite four and get the ruby and Sapphire then you can get into the cave to catch mewtwo
you have to beat the elite four again then you can look for the legendary dog things
Beat the elite 4 and after go to the cave in cerulean city.
