P.S make sure you have some tough Pokemon because there are a lot of tough Pokemon in this cave, though I am sure you will have no problem since you did beat the elite four =)
Edit: Before this, you have to beat the elite 4. Then make sure you have caught 60 types of pokemon and get the national pokedex from prof.oak. Then go to island 1 and celio will say you need to fix his machine. then go to mt ember (surf to the top of island 1) and go all the way to the end. After you get the ruby, then go to island 4 and find lorelei. After that, go to island 6 and go to the bottom and you will find dotted hole. Bring someone who knows cut and cut the door open. Then read the braille signs and reach the bottom and a scientist will take the sapphire away. After that go to island 5 and find the rocket warehouse. Beat the last guy (he's so easy) and get the sapphire. Lastly go to island 1 and give the stuff to celio.
Mewtwo is level 70 and is very very strong.
beat first the elite four then go to cerulean city and go to unknown dungeon. hope it helps.
07meowth says, catch mewtwo in pokemon firered, then migrate it.
Mewtwo is the strongest pokemon you can catch in that game.
After you catch mewtwo you go and beat the Pokemon league again to go and catch the legendary dogs!!!!!!!!!!

You can't. You'd have to trade it from a Pokemon FireRed or LeafGreen game.

No two Pokemon make mewtwo ,you must catch it in firered or leafgreen and if you want you can migerate it to diamond or pearl.
go to the sevi islands w/ rainbow pass
uhh... you can't...you already killed it
1. you cant catch mewtwo on ruby emerald or saphire<spelling mistake> you can migrate the mewtwo you catch on leafgreen or firered to migrate to platinum
i dont think you can get rares that are shiny but only if you have gameshark
how do you catch a mewtwo on Pokemon platinum
Beat the Elite 4 then yhe guy will move and you will be able to catch mewtwo
To catch Mewtwo in LeafGreen or FireRed no. To migrate Mewtwo from LeafGreen or FireRed to Diamond/Pearl/Platinum yes you have to have it in Diamond/Pearl/Platinum.
