It doesn't really matter what Pokeball you use. The only thing that matters is how long it takes to capture it. I caught Mewtwo with A POKEBALL, I caught my friends Mewtwo with a Timer Ball, I used my Master Ball on Lugia, and I had no problem cathing the other Legendaries. It's just a matter of timing, patience, and HOW GOOD YOUR POKEMON ARE. That's all the advice I could give. GOOD LUCK
My opinion is Get Mewtwo to red health and use
Hypnosis or Thunder-wave. with Mewtwo asleep it would make
four times easier then Mewtwo normal. Making it paralyzed will make it twice as easy.
when you've got MewTwo to Paralyzed/Asleep i suggest you yousing the following.
Dusk ball (at night)
if you are lucky just throw a quick ball at the start for luck because i caught Giratina Lvl 70 in diamond with a quick ball!
Master ball....................Hope this helped *-*
I prefer to use my Master Ball for Mewtwo, but at least use an Ultra Ball.
You can probaly catch him with a ultra ball but I would use the master ball
if you dont wanna waste your master ball, then the strongest ball will be the Ultra Ball...
Use you masterball on suicune because its impossible to catch it without a masterball it would just flee i cuaght mewtwo with a great ball but make sure you have lots of them.
a master ball preferably but any ball will work with a bit of luck
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.
you know lengendaries are hard to catch,but some are normally hard.just use dusk ball or ultra ball
Mewtwo can only be caught with a masterball i think
You could use it to catch one of the legendary cats.
3 or 0.4% throwing a poke ball at full health it's better to use a master ball.
Mewtwo I guess????
It is your decision, but to I will use it on mewtwo or entei
You have 2 beat the game, then go 2 the cave in cerileon city, deep in the cave you will find the ultimate Pokemon known as Mewtwo! TIP: use a master ball or its almost impossible 2 catch it!
I would suggest a strong DARK type pokemon, because then Mewtwo wont be able to use its Psychic attacks.
once you get into the cave go through it and catch mewtwo i recomend saving in front of him i tried to catch him with a ultra ball like 10 times and couldent catch him but, i had to use a master ball.
you have to go to code breaker code and use the code to catch a mewtwo.
Save your MasterBall for the Ledgendary dog (Suicune, Entei or Raikou). Don't use it on Mewtwo because it is really easy to catch him with just ultra balls. Just make sure you save before you fight Mewtwo :)
you should use it on lugia. he is the hardest one to catch. you cant catch him with any other pokeball. you can only catch him with a master ball.
Mewtwo is at Level 70 when you battle him. You should most likely use you highest level Pokemon that is around level 70.
NO WAY! sorry for those of you that it is too late for, but you should save your master ball for Mew or Mewtwo!
You can't catch mewtwo in Pokemon diamond. It's better if you use Action replay code.
The best ball to catch Deoxys is a Master Ball or a Timer Ball! Trust Me!!! Pokemon Master
