Back when I first played Silver, I was trying to level a pokemon by fighting low pokemon and a green ekans popped up, and I thought it was a glitch and tried to catch it but failed miserably. My first ever shiny...
It\s been forever since I played, so Im just getting back into the groove is hard. Luckily they made it easier to click!
And it was in the cave where you find Solrock and Lunatone, it caught me by suprise! Luckily I caught it!
I have a few, including two with a Master ball!
Back in the good old days of Silver, I used my Master Ball on a Dratini. All because the Dragon Elder said " Dratini's are rare!"
In Sapphire, I never found the Master Ball.
Found a Shiny Ekans in Silver once, thought my game had problems...
