What was your first shiny Pokémon? Was it a random encounter, or were you hunting for one? Mine was a Foongus, Pokémon Y, Route 15, random encounter. It is now an Amoonguss named Master Ball.
Mine was a shiny Gulpin in a horde in Pokémon X. It's not exactly my favorite Pokémon, but I was still super excited because I'd never seen one before.
Besides the red Gyarados of Gold and Silver, my very first randomly encountered shiny was a dark-petaled female Roselia, caught in the post-game area of Pearl version. I was in high school at the time I caught her, with no prior knowledge of differently colored Pokémon besides Gyarados, so I thought it was some kind of glitch at first, and showed her to my friends. They were all so jealous. To this day, I still have her as a Roserade in my Ultra Moon file. She was the first of many, many shiny Pokémon I currently own. XD
First shiny I encountered was an Electrike in Sapphire. Didn't catch it. My first caught shiny was a Minun in Emerald. He's long gone now. Lol
A Rayquaza. In the original Sapphire. ._. I'm not joking, I spent a day RS'ing for it when I was back in middle school. The hype when I got it was real.
My first (non-event) shiny was a Nidoran male that hatched from an egg while I was breading Pokémon to trade away on the GTS to fill out my Pokédex in OmegaRuby. He ended up replacing his father in my team and I still use him occasionally.
Mine was the lake of rage Gyaridos in Pokémon gold. I didn't get another shiny outside of events until I did online trading in gen 5. My first self obtained wasn't until gen 6 with friend safaris, I found so many I can't remember which was my first.
My first shiny out of the two I have, was a shiny sandshrew here. Green being my favorite color, I did everything I could to catch it, which I did! I didn't look up what a shiny sandslash would be though, and cried when I evolved it because I didn't save after I caught it. Later I caught a shiny wingull the exact same day. Didn't even attempt to evolve it, just gave it tat stone tat doesn't allow it to. It also mysteriously disappeared, although I saved after learning my lesson.
My first hunted and caught shiny was a Lairon in X, which I got in 2014 through full odds random encounters. His name is Promethium and I still have him, he's an Aggron now But my TECHNICAL first shiny was way more wack... It was my first time playing Pokémon and I was playing SoulSilver. The first Magikarp I ever saw was yellow and sparkled, but since I had never seen one before I just thought they were all like that because it had magic in the name. It was only after I ran and tried to encounter another that I realized something might've been amiss, but I don't think it bothered me much until I found out what a shiny was. The kicker is that, even if I had caught it, nobody would've believed me since it was at the Lake of Rage. And since I was like 13 I defo would've evolved it
I was preparing to fill out my Pokédex in my Pokémon white game and so I went back to emerald in search of a trapinch I could transfer over because I wanted a flygon. I searched the sandy desert, but I was getting annoyed by all the baltoy I kept finding. Then the first ever trapinch I found was completely silver. I freaked out and caught it right away. To this day, I still have the shiny flygon in my white game.
my first shiny was a shiny horsea in fire red! i decided to fish randomly once, and while i didn't really know what a shiny was, the sparkle seemed really special so i caught it. i evolved it to seadra, but unfortunately, i reset that game so it's gone forever
By technicality my first shiny was a shiny Ponyta in Diamond that I hacked with an Action Replay after spending days trying to hunt for one unsuccessfully (mostly because I didn't have the concentration for gen 4 shiny chaining when I was 11), but my first legit shiny was while I was running around looking for Latias in White 2, I encountered a shiny Patrat. I had a distaste for the Patrat line but caught it anyway, and I think it's still on my Pokémon X file nowadays? Other shinies I've found since then have mostly been through intentional hunts, but I've caught unexpected encounters along the way.
Shiny Bidoof! I was hunting but not for him. Still quite happy with it since I am canadian my friends said it was fate I would get the beavermon
Like many others, my first shiny was the red gyarados at the Lake of Rage. My first random encounter was a shiny darumaka in Black. She's a darmanitan now and is currently on my Moon version, though she hardly gets any use these days.
Not counting the red Gyrados in the Lake of Rage, my first shiny was my shiny Vulpix (now Ninetales) named Sasha in Let's Go Eevee. I randomly encountered her, and got so excited. My brother and sister were so jealous. They both became even more jealous when, just a few days later, I caught a shiny Pidgeotto and named him Lute. I wasn't even hunting for them, I was just grinding and they showed up.
Outside of Gyarados, first shiny I remember getting was a Jigglypuff in Heart Gold's Safari Zone. I promptly put it up on the GTS for a Totodile.
Besides the Tapu Koko event in Moon, my first shiny was a Fomantis in Moon I randomly found. It's now a Lurantis.
