What did you use your master ball on?

[poix_the_yak]

I haven't used mine yet.

 

[Venomfrog]

Latios. I ran into the dragon at random and thought I might as well catch the first legendary of my life the easiest way.

I likely will not use Latios, though, except maybe for fun.

 

[Lorde]

Sapphire: Nothing, didn't find it.

Ruby: Latios for Sapphire version

Emerald: Latias for Sapphire version since I didn't get it in Sapphire ;_;

 

[Agonist]

Haha, cloned it, now I have like 200+masterballs, probly can stop cloning it but to lazy to

 

[Scrible]

The first time I used it either for Groudon or Rayquaza (can't remember). This time around I'm going to use it for Latios

 

[KGB13]

I always use my masterball on the mascot legend.

Ruby: Groudon

Sapphire: Kyogre

Emerald: Rayquaza

 

[Dark Eevee]

Lati@s. The mascot legendaries are easy to catch.

 

[Kyogre911]

i used the emerald glitch to get lots of them

 

[Blue Shiny Pikachu 1]

Latios but I haven't found him yet. I am going to use it on him though.

 

[DaAuraWolf]

I used my master ball in emerald for Raquzza.It was my main Pokemon in the elite 4 challange.

 

[Dan The Poke Man]

Rayquaza because I didn't know that the latis were in the game.

 

[Milotic<ftw>]

rayquaza and def should have waited for latias/latios. Sucks to try to catch it even with mean look

 

[Rosemary]

On sapphire I used it to caught Latias.

 

[junpearl63]

I used it for Rayquaza.

 

[Illusione-Tempus]

For Rayquaza... with a red HP... I'm soooo stupid *headdesk*

 

[Ash-kid]

Rayquaza. I have captured a Groudon with a regular pokeball.

 

[PsychedelicJellyfish]

Ruby and Emerald: Latios
Sapphire: Kyogre (I was only playing through to get it to transfer to Diamond)

 

[diablo_200525]

Rayquaza due to the fact that i didn't know there are others after him >>;

 

[rekreatur]

Rayquaza, I think.

 

[rioT6296]

I used it on Rayquaza...because I didn't know that there were other legendary pokemon I could catch. I thought it was the only one.

Another stupid thing I did: attack Rayquaza until it's HP was orange...then realizing that a master ball could catch a Pokemon without any failure AT ALL. >.<*
