Mewtwo appears only in Fire Red and Leaf Green. You can catch him in either of those games and then trade him to Pokemon Ruby.
sorry mate its impossible only way is to trade like this guy said (: (: (: (: (: (: (:
I regret to tell you that you cannot catch Mewtwo in Ruby. You can only catch Mewtwo in FireRed or LeafGreen. (You can use cheats to get it but it wouldn't be as fun).
Mewtwo is at Level 70 in LeafGreen and FireRed so use an Ultra Ball/Timer Ball/Master Ball.
If you need/want a Mewtwo you can trade Mewtwo into your Ruby/Sapphire/Emerald Game.
Only if you have a code breaker and the master code for ruby plus the mew and mewtwo code
You can't. You'd have to trade it from a Pokemon FireRed or LeafGreen game.
Unfortunatley, you cannot catch Mewtwo in Pokemon Ruby/Saphirre/Emerald. But you can trade it in from Firered/Leafgreen. Also, instead of asking on Answers for Pokemon questions, just go to Serebii.net
how do you catch a mewtwo on Pokemon platinum
trade mewtwo from leaf green
With a Masterball
you have to have beaten the elite four and you have to find the ruby and sapphire for the machine in the Pokemon center on one island. then you can enter cerulean cave and get mewtwo
the sapphire needed to unlock trading to pokemon ruby and sapphire...and you need it to catch mewtwo
Mewtwo is unavailable in Omega Ruby and has to be transferred from another game
give him the ruby on island six, then you can catch mew and mewtwo
you don't get mewtow in ruby
You can't catch Mewtwo on XD, Colosseum, Ruby, Sapphire or Emerald. Mewtwo can be caught in the Fire Red or Leaf Green Version then traded over to Emerald, Ruby, Sapphire, Colosseum or XD.
No you can't catch Mewtwo in Pokemon silver, you must trade it from Pokemon yellow.
You cannot catch Mewtwo in DPPT
You can't catch Mewtwo in Pokemon Diamond and pearl and also platinum. But you can catch Mewtwo in heartgold and soul silver
You can get it from firered or leafgreen.
Catch 'em all
Mewtwo is not available in Pokemon Omega Ruby or Alpha Sapphire. You will need to trade for it from the previous games such as X and Y.
Mewtwo, yes, if you have a FireRed or LeafGreen with Mewtwo.
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
you cant catch a man in Pokemon ruby
can only get mewtwo through trade in Pokemon emerald
the mew code for ruby is 71E09BD117FDFD02 and mewtwo is 30621E6F164FED85 these are the right once i think
