Who to use the Master Ball on?

Who do you think is the best Pokemon to catch with the Master Ball in each game. I suppose Mewtwo, in the first games, but what about the rest??

I dunno, but I usually try to save the Masterball and use other types of Pokeballs (eg. Fast Ball for Suicune, Entei, Raikou) for catching legendaries. I think it's more fun and challenging this way.

I use Masterball for those stupid fleeing legendaries. (The dogs, Lati@s.) The other legendaries you can just restart and try again. The fleers just take too long and annoy the heck out of me. But that's me. :)

I use masterball on my favourite pokemon! Because it will some how make it different and special than others? :paranoid:

Rave :dead:

first:mewtwo
second:celibe
third:raquaza

thoose r the best to use a MB on.

I'm playing sapphire and I made a mistake and didnt even get a chance to catch raquaza and now I dont have any thing to use it on exept latios..but I dout i find him any time soon

Erm...you don't have to use the Masterball on Mewtwo. I caught it with a Pokeball. I still remember it. I had already used my MB on Zapdos. All I had on me were Ultra Balls and Mewtwo had one tiny chunk of HP left. 99 Ultra Balls later, it was still there. Then I chucked a PB at it...irony. Then I read it's Dex file and it said it can't stand being in a PB. Gah!

RBY: Zapdos (I hated that thing)
GSC: The final dog I need to catch (with the exception of Suicune in C)
RS(E?): Lati@s

i just keep it, put it on a pokemon, and send it to an important game where im trying to catch them all
so i restart my games alot, i just catch all the lengendaries with great balls, not very hard

i never use my masterball. i dunno why
my opinion:
RBY: Mewtwo
Gold/Silver: Gold: Lugia, Silver: Ho-oh
R/S: Lati@s or Rayquaza

Maybe it's just me, or maybe it's some sort of weird luck, but I find some legendaries are easier to catch using lesser balls. For example, when I was after the Regis, Ultra Balls were useless - as soon as I threw one, they popped out straight away, no shaking at all. I threw a Great Ball, and lo and behold, the balls start shaking. And I have Entei (from Colosseum) in a Pokeball.

Here's what I used my Master Ball on in each game:
Red: Mewtwo
Blue: Mewtwo (yeah I know)
Gold: Raikou
Silver: Suicune
Sapphire: Latias.
Colosseum: Tyranitar.

My list:

YELLOW: Mewtwo
CRYSTAL: all legendary pokemon :P
RUBY: Latios.

Red/Blue/Yellow: Mewtwo
Gold/Crystal: Lugia
Silver: Ho-oh
Ruby: Latios
Sapphire: Latias
Colosseum: Tyranitar

(I'm one of those people who has ALL versions of PKMN!)

use it on latios or latias in RS

I'll use mine on mewtwo.... But only if I run out of other pokeballs first :D

you shouldnt need masterballs if you have a pokemon that prevents escape or one that can reduce defense for the rest, i use timerballs, the catch rate goes up each time you throw them and should definately work before you throw 11, if not then start over(or not if youre after a flee'r)

I don't use a Masterball either XD. I save it. It looks pretty XD

RBGY: use the mew glitch and get mew with it.
GSC: celebi.
RSE: latias or latios, whichever is in the wild. us timer balls on the shouthern island one.
RSLG: mewtwo.
My porkymen lab hack: the great shiny charizard! it is inside the pokeball left by joey when he drops his bag in the laboratory. you awaken it and it attacks!

Once in pokemon blue, I used my master ball on a caterpie and caught Mewtwo with a poke ball. It was really wierd! (Mewtwo had 2/3rd's of its hp left aswell)! :)
