What did you use your master ball on?

[Pkmn Trainer Rover]

I have Ruby, but I only beat Emerald. Never going to have a master ball in Ruby. Anyways, in Emerald I used it on Latios. I randomly found it when surfing and I didn't want to take any chances! On Rayquaza and the rest I used ultra balls.

I have many games so i have many masterballs( I don't cheat or glitch):
First one: Zapdos (I first used it on a grimer but my friend taught me how precious they were and i restarted my leaf green game to use it on a legendary.....I was 8)
Second one: Rayquaza
Third one:Entei
Fourth one: Raikou
Fifth one: Reserved for Pokemon Black
Sixth one: Going to use for trade purposes

Rayquaza, I wanted him so bad I was not gonna let him go so I used the masterball on him.

Kyogre on Sapphire (I was a rookie back then), and I saved in on Emerald. Also why didn't you add the regi's in the poll?

something stupid

Ruby: As my brother really likes ralts he caught ralts with my masterball!!!
Sapphire: I first got it and didn't know what it was so I caught a Pikachu
Emerald: I got Zangoose cos it looks cool

I clone them on Emerald and Pal Park them to Platinum.

Uh i used mine on a Shiny Zigzagoon (it was really hard to catch!) me in my nooby days..

Emerald: I cloned it and used it to catch all the hard to get things. I still caught Rayquaza the legit way, though.

OTHER (explained in post)
I cloned my master ball before using it so I've used it on every Legendary except Rayquaza. There is a cool glitch that gives you 10% more chance to catch a pokemon when it is flying(or bouncing or digging or hiding(giratina)). Rayquaza at full health is -9.871% chance of catching in an ultra ball but while flying there is a 0.129% chance of a catch it took me 5 days to catch it(why did i do that?).

The regis stat are lower than other legendaries and you can catch them in pokeballs( no specials here) with 1/3 or smaller health. No cheats just regular catching a wild pokemon. Absol has higher base stats making it MUCH harder to catch.

Ruby and Shapphire: Didn't get it so didn't use it (amateur back then )
Emerald: Used it on my Latias

 

[Paul Ketchum]

I used my Master Ball on every obtainable in-game legendary because I cloned it.

 

[Carina]

I don't think I've used ANY masterballs since the Blue/Red days. Cloned it heaps of times with Missingno, of course...and used it on Mewtwo.
But with my Silver, Leafgreen and Emerald games, I never had the heart to use my masterball on anything.

 

[AZX612]

The very first time in my Sapphire (I was 7) I used it on an Absol because it looked so cool and I never seen it before and I didnt know if I would ever find it again. So worth it = )

Well, at the time it was . . .
