Welcome to the Battle Tower. - Palmer
It was in Pokemon Emerald, where I just had calmed down Kyogre and Groudon from destroying the world. My pokemon were still around level 50 ~ 60s. After Rayquaza flew away I went back to the Sky Pillar, only to find ugly cracked holes and stuff. I had experience with those cracked holes from the Mirage Tower with the Claw/Root fossil, so I easily got through. I had no idea that there was Rayquaza in it, and I did not check if I had enough balls. I saved, and encountered Rayquaza to a battle.... then... WHOAH HOLY MAGIKARPS, THIS BLACK AND YELLOW RAYQUAZA OMG ITS A SHINYYY AHHH
Then I proceeded to get it down to the lowest HP possible. By that time I had only my HM slave alive, which was my Grovyle I never bothered to level up. In my bag I had like, 40 Poke balls and 40 Great balls, no ultra balls or whatsoever. I think I had to quit/reload for about half a week constantly throwing great balls and no success, until one day I just was spamming the A button and not paying attention. After a while I suddenly was out of battle. I was frightened I might have killed Rayquaza, and proceeded to my PC, then I found the Shiny Rayquaza, caught in a Poke Ball with the nickname AAAAAAA...
