yes, you can but it is VERY hard i suggest using a master or ultra ball one person on YouTube caught all the legendary birds and mewtwo with a pokeball without cheating you should watch them
Moltres, Zapdos, Articuno, Mewtwo, Lugia and Ho-oh (by event), Raikou/Suicune/Entei, Deoxys (by event).
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.
You possibly think of catching other people's Pokemon?? That's cold!! Coz if you attempt, you'll be losing pokeball/s... You can't just throw a pokeball on other's Pokemon, coz that's stealing..
i dont know why everyone thinks there is a mew in fire red. there isnt! but lucky for you my friend.... there is a mewtwo in Cerulean Cave
You must complete some stuff. Yu have to get the national pokedex(yes, 60 pokespecies and then prof oak) then you have to get Sapphire and ruby for Celio
Well it matters what game you have, if you have Pokemon fire red, you can catch it with a master ball
You cannot catch Mewtwo on Emerald. You have to trade for it on Fire Red or Leaf Green.
First you got to catch him in Pokemon leafgreen or fire red and trade. Or you can use a gameshark. it lets you catch all the Pokemon from bulbasaur to deoxys.
No it is not possible.
one thing you like can't catch manaphy in like ANY game another thing you can only catch mewtwo on Pokemon ranger and Pokemon fire red and leaf green.
You can not catch mewtwo in the wild on pokemon diamond, you can only get it by trading with someone on the GTS or someone you know. The other way is by pal parking the pokemon from fire red or leaf green to your game.
Zapdos, Articuno, Moltres, Mewtwo, Entei/Raikou/Suicune (depends on what starter you chose).
You can't get a Mew unless you cheat, I think. A Mewtwo you can only catch in Fire Red\Leaf Green and transfer to your Pearl.
ANSWER 1: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 (: (: (: (: (: (: (:ANSWER 2: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.
Migrate it from fire red, leaf green, Ruby, Sapphire, Emerald, or trade it from Diamond or Pearl from someone who already has one, or use action replay.You just catch it in the Pokemon league. On the 300th Pokemon you battle there, the old Pokemon will faint and Mewtwo will appear. Catch it with a regular old pokeball.* Don't attack Mewtwo or he will disappear!*Trade it from fire red to emerald to diamond and catch it in pal park.In order for you get Mewtwo in Pokémon Diamond you have to migrate it from either Pokémon Ruby, Sapphire, FireRed, LeafGreen or Emerald. If you have a friend that has one of those games and he/she has only one Mewtwo then you could tell your friend to put Mewtwo in an empty PC Box. Save the game and when it says don't turn off power, turn it off and on again. There will be 2 Mewtwoss exactly the same, same moves, levels etc. Your friend now has 100 Mewtwoss! Put the Gameboy game (Ruby, Sapphire, FireRed, LeafGreen or Emerald) in your DS and migrate. Transfer Mewtwo from the games via Pal Park (Route 221). Mewtwo will be wandering around in grass areas inside the Pal Park.
Moltres, Zapdos, Articuno, Mewtwo, Lugia and Ho-oh (by event), Raikou/Suicune/Entei, Deoxys (by event).
after you catch mewtwo in Pokemon leafgreen/firered if you havent done so already you can explore the 7 islands.however if you already have done so there is really nothing left to do
