RSE What Pokemon did you use the Master Ball on?

[PEDRO12]

Well I don't remember how much, but I caught all of them with Ultra Balls except Rayquaza and Latios.

Rayquaza ~ Pokeball (Only 1, found out it works a lot better when Rayquaza is flying xD)
Latios ~ Master Ball

[Frio Stylez]

It was either Pelipper or Kyogre, I don't really remember what I used it on.

[EQUALSGAMER]

I accidentally skiped past the masterball party. note these are estimates i dont know exactly how many i used.
kyroge timer ball (34)
regice timer ball (37)
regirock timer ball (26)
registeel timer ball (89) i tried a couple times at him. Funny story when i first got emerald i found the regi's caves and the the that opens there caves an knew they were in the games but being a little kid i didn't use the internet but i recently picked up my sapphire again and got the regis all in one night. Got no sleep that night.

I ended up using my master ball on a latias. However, after I accidentally deleted that file (don't ask) I ended up using superskarmory's guide on youtube the second time. He ended up catching it in a regular pokeball, so I went "Pffff, I can do that!", so after 2 hrs of sleep powder I finally caught it. Then I showed my brother and he ended up catching it in a premier ball the next day. From that day forward, I catch all legendary pokemon in heal balls, because I can.

Rayquaza - 26 Ultra Balls and 1 Pokeball
Latios - Master Ball
Mew - 5 Ultra Balls
Deoxys - 60 Ultra Balls

[Batel]

I used my Matser Ball on... Groudon. Yes, Groudon.

I made some notoriously newbie mistakes that my friends laughed at me for in that game. Looking back, I don't laugh. I just get embarrassed. ^////^a

[Agastya]

Ruby, I used it on the mandatory Groudon they threw at you.

I imagine people playing Sapphire usually bust it out on Kyogre since it cleans the rest of the game easily, but maybe they get away with Net Balls?

[drpoplove]

In my first run I used it on Kyogre in Sapphire. But I smartened up later, haha.

[Olli97]

The first few times I played through my Ruby, it was always on Groudon, and being young isn't really any excuse for me, since I usually did know it was best to save it for other ones (well, usually I just wanted to save it for Rayquaza, whereas saving it for Latios would've been a much better idea lol), and in the last playthrough I'd forgotten where it was even located due to it being so many years since I'd played it, and since I was in such a rush to get through the Magma hideout, I missed it, and didn't even get it that time. Ended up catching all the legendaries I was going for in regualr Pokeballs anyway lol

[Pooba86]

On my first playthrough of Ruby, I used it on Groudon. I felt like an idiot after I found out how hard it was to catch the other legendaries.

[Mr Cat Dog]

I definitely remember obtaining a Kyogre when playing through Sapphire. Presumably, me being a lazy 13-year-old, I wouldn't have wanted to deal with a big epic battle to get the super-cool-awesome Water legendary so... Master Ball it is.

[Toshiro.]

Always the big legendaries. Groudon, Kyogre, and Rayquaza. Didn't feel like going through the whole process of trying to save it, so yeah.

[60]

I couldn't exactly find Lati@s, so yeahh...I used it on Regiice my first time through.

All the others I can't remember, but it took an insane amount of Ultra Balls.

[asitha_lakruwan]

I used mine on Kyogre. I used an Ultra Ball on Rayquaza. My friend found a shiny tentecruel Lv. 38 and wasted it on that.

[ThatOneGolurk]

Emerald:

Groudon: 23 Time Balls and 14 Ultra Balls
Kyogre: 76 Dive Balls. He just did not want to be captured.
Rayquaza: 20 Ultra Balls.

Latios: Master Ball.
Latias: Never managed to get it. :/

Regice: 39 Ultra Balls
Regirock: 27 Ultra Balls
Registeel: 64 Ultra Balls and 5 Time Balls. Took me a lot longer than I thought.

[Blue Emerald]

In Ruby, it was Groudon. Sapphire, it was Latias, and in Emerald it was Rayquaza.

[BLOOOD-La-ti-]

I only use the master ball if the wild pokemon is struggling.I rarely use the master ball if they are hard to catch.

Ruby: Latios - Due to struggle
Sapphire: Latias - Also due to struggle
Emerald: Deoxys - He's too weak he always gets knocked out
FireRed: Mewtwo - Although he only has psychic,He's too powerful
Leafgreen: Lugia - Due to struggle again..Before he used that,he kept on using recover.Which is pretty annoying

And that's about it

[tajaros]

Here's the Pokemon that I used them with.

Ruby: Latios
Emerald: Idk, why but I used it to Rayquaza... xD
Firered: Suicune (I picked Charizard)
Leafgreen: Raikou (I picked Blastoise)

[vaporeon7]

Because of my need to hoard rare items in every Pokémon game, I still haven't used my Master Ball yet. Everything isn't that hard to catch anyway.

[Pinkish Purple]

lol I'd also love to do that but no patience

[Snivysmiley]

On my first play through I had no clue what a master ball was... Relicanth....

[glitchguy]

I was pretty much a noob back then so i used it on a Groudon in Ruby.

[Pinkish Purple]

Naww, using it on Groudon is still quite ok

[Wateria]

I think I used my masterball on Kygore or Rayqazua on my Sapphire. On my Redfire probably one of the trio legendary bird trio.

[toasterr]

Poochyena.
I have my friends to thank for that.
Catching Rayquaza took forever.

When I'm emulating, I rarely use the Master Ball because save-states and non-static RNG.
