Yes I have!..I think it was in my first Emerald...I used my master ball on my four hundred thousandth Skitty (I'm clearly exaggerating XD) but I still have boxes full of them before that and I think I had two in my team and I didn't know how valuable the Master Ball was back then so I used it in that situation..yes I was constantly looking Skitty by Rusboro City and caught everyone I found!..a little strange right? XD

And when you find a Legendary and wished you saved that goddamn Master Ball! xD How many times I've wasted one on a Pokemon that doesn't matter or could've been caught if I bothered my butt to lower it's health more, I cannot count.

When I was young and stupid I threw a master ball at, get this, a Machop! A Machop! Can you imagine?!?

Actually at the time I was happy about it..I didn't think about the Legendaries very much XD

Do shinies count=)

^ I haven't thought of that..mainly because I've never had a shiny but that's also a good time to use a Master ball!

Once by accident

Never have never will

No i haven't, actually i didn't cared about it until i came to knew what it was xD

I have never used the Master Ball, so I just use it on a Pidgey or something xD

@vanila that's because master balls make it too easy.

personally, i don't like using a master ball on a non-legendary pokemon cause i don't think i can get another one

First time I got one, I was stupid and didn't know I could only get one. I threw it at a Sneasal.

On many Mightyena,Poochyena,Camerupt,Numel,Sableye­,To­rko­al and Trapinch.

My game glitched so I ended up with a heap of Master Balls that I was considering discarding but changed my mind it would save me buying Pokeballs
