Who do you use the Master Balls on?

[d00bt00b]

I only use masterballs on shinies, just to be safe, or I will give it to someone in exchange for one of their starters.

[Ðelta]

I try not to use the Master Ball entirely, but I will use it on roaming legendaries if I don't have an escape preventing ability/move (which I usually have).

If I see a shiny, though, I'd use the Master Ball in a heartbeat. Much more important than a roaming legendary.

[Toshiro.]

I actually don't really use my Masterballs anymore. I haven't in a long time. I like to catch legendaries with Ultra Balls. I guess I would say I use them on the roaming Pokemon, such as Latios or Latias for when I don't have someone with Mean Look or just don't feel like trying to use other Pokeballs.

[Isseubnida]

Roamers, or in BW2'S case, some other legend, or even a shiny.

[Xulek]

I used my masterballs on your mother last night.

Jk, kind of XP

Seriously though, I use em on any roaming legendary since tracking them down the old fashioned way is unbearably boring at times.

[LilJz1234]

I only use the Master Ball if I encounter a shiny Pokemon or a roaming Pokemon. If I don't encounter any of those by the end of the game, I just use it on the main legendary of the game.

[⊗Slenderman⊗]

I used one on Raikou (sorry, can't remember how to spell it haha), which was a mistake. A different one, I used on Dialga, I think.

Now that I have two hacked games, I have mass amounts of masterballs. I always have a few on Diamond version for shiny hunting. c;

[B-L-A-Z-E]

I always used it on a roaming Pokemon but in bw2, I've never used it since there aren't any roaming Pokemon.

[Scarf]

I always save my Master Ball on the off chance that I encounter a shiny which I don't want to risk loosing. So far I've encountered all of zero shinies so my Master Ball always sits in my bag.

[glitchguy]

I usually save masterballs for legends but don't really plan on which legend to use it on except if the game has a Mewtwo in it.

[JNathan]

I used Master ball on Zapdos first then when I re-played LG on Mewtwo.

[Jolteon82☆]

Usually I don't use them, I think I've only used the master ball on Lugia in XD, and Thunderus in white lol

[Zorogami]

Back in RBY i used my Master Ball on Mewtwo, like almost everyone else.
After that, i usually catch one of the roamers with it, just to avoid the endless searching and capturing.
I always have the faint hope to use it on a shiny one day...but i have never seen one

[Tackle]

I always use Master Ball for a Legendary Pokémon that I need to roam.
Seriously I won't use Master Ball for main Legendary, I'll use Ultra Ball instead.

[speedokaggen]

Firered: Mewtwo
Crystal: Suicune
Emerald: Rayquaza

[PersianTrainer]

I just used my master ball today. Like I promised myself, for a shiny Pokemon, and caught one today. A shiny Mienfoo.

[imevil]

Only on roaming Pokemon, if there arent any then I trade it to another game. Or maybe on a Legendary I just can not catch.

[lazy~]

I use it on any legendary who becomes a real pain to catch, although I do remember using it on a Graveler in the original gold back when I was a noob.

[Da7kmagician]

Roaming pokémon usually. If there isn't any then a legendary.

[Alakazam17]

I use them on the Pokémon that I generally consider to be the hardest to catch.

RBY: Mewtwo, definitely.
GSC: Lugia or Ho-oh, whichever is higher leveled. I'd consider the dogs, but I enjoy the chase, and Fast Balls are a good alternative anyway.
RSE: The version mascot. Same reasoning for not using it on the roamers.
DPPt: Cresselia or Mesprit. The version mascots are easy enough to catch IMO.
BW: Tornadus/Thunderus. Same reasoning as above.

[PlatinumDude]

As many people before me said, I use my Master Balls on roamers just because I can't be bothered weakening them, and chasing all around the region them.

[SchwarzRozen]

I haven't used a masterball sense the days of Ruby and Saphire
I started to learn how to catch the roamers without a masterball, and I was well off

I save it for things such as Shiny Abra or Shiny Exploders.

[Muani]

It is always easy to catch the 'main' legendary [e.g rayquaza, zekrom, palkia, dialga] with Ultra Ball.

I will use a Master Ball on the Pokemon that runs all over the region, like Latias/Latios. Only if I cannot get it with an Ultra Ball first. Sometimes, I end up not using my Master Ball!

[Aerilyn]

I honestly can't recall the last time I used my Master Ball. When I first started playing Pokémon, I always used it on the game mascots. When I finally got some sense, I started to use it on the the running Pokémon. Now, I barely ever use it at all. I use other techniques to catch free roaming Pokémon and the mascots are pretty easy to catch using Ultra Balls.

[tabor62]

I no longer use Master Balls, there's no challenge if you use them (yes, I'm weird) and they don't even look that great to be honest.
