My first non event shiny in all my years was actually a Riolu I was breeding in ORAS... Man I have bad luck.
Mine was a Marill followed later by a Numel on two different resets of my Pokémon Emerald. My most recent one was a WIshiwashi I got on Wonder Trade in Sun that I choose to keep for potential breeding purposes due to its IVs.
So just not long ago. I was fishing and caught a wishiwashi. I saw a typical color. Buy didnt see the shiny entry. So great ball. Typical getting caught. Quickly checking was it a normal wishiwashi dX
Obvious answer: Red Gyarados 1st random encounter: Sixth island, Dotted Hole pond in the water... Magikarp. A golden Magikarp. I forgot about the Red Gyarados and thought it evolved into a golden Gyarados.
Shiny Shinx! It took forever to find since I was using the PokeRadar chaining method in my Diamond version, but it was so worth it because of how adorable it is
Second playthrough of Silver, I found a shiny Onix in one of the caves. I can't remember if I caught it or not. Since then, I've only found two others.
My first encounter was a Shiny Kecleon in Pokémon Ruby when I was 7. Pretty sure that I had killed it by accident (Multi-hit move). I did catch a Shiny Audino is Black a few months ago. Unfortunately, my battery corrupted right at the time I saved the file so, goodbye Shiny Audino. My most precious Shiny may be Shaymin, which I received from an event. It now moves to Alola and helps me go through the game with ease. I'm still trying to get a Shiny Shinx in Diamond (Pretty hopeless cuz I have been searching for it for years)
Been playing Pokémon for 12 years and still have never encountered a shiny besides the Red Gyarados in GSC ;w;
Oops. I did that in gen 4. There was one in gen 2 I ko'ed. Now I can't recall which it was. One of the common ones.
My little sister actually found my first shiny. She was playing my Pokémon Pearl game and called me over when she saw a discoloured Ponyta. Naturally, I flipped out and took extra care to weaken and catch it. I've never found another shiny since, but my sister found a shiny Gloom on her copy of Pokémon X.
It was shiny taurus, full odds and totally random in the wild, I have trouble remembering which game though it was before 3D graphics, probably HG/SS. I was so torn between joy at finally getting one and the fact that it's some serious highlighter yellow and neon green @ _ @ - I'm still weirded out that even though I don't believe in star signs it seems like quite a coincidence being that sign and that being the Pokémon I found.
Shiny gyarydos was my first but the next one after that was shiny magnemite. Still have it and man did I clone the heck out of it at the battle tower in emerald.
My first shiny I actually TRIED to obtain was a shiny Rowlet in Moon, Ga'hoole. The first shiny I ever encountered was a shiny Tentacool, I thought my game was broken when I found it (I was 6 at the time) My first caught shiny was a Shiny Lotad in Sapphire.
The first shiny I encountered was actually a Roselia I didn't know they existed so I was extremely confused and I believe that was in Pokémon Pearl. After that it was a Shiny snubull.
I've only had it happen once. I can remember it like it was yesterday... Flashback to 2004, Pokémon Sapphire, and I was running around route 102 after Wally had caught his Ralts: [3D='shiny-wurmple'] Bam! My friends didn't havy any. No one I knew had any. I would not have known what it was I was seeing if I hadn't already read the Official Nintendo Guide for Firered and Leafgreen, the page where they showed examples of 'shiny' Magikarp and Oddish (I can't even find a pdf anywhere online so you just gotta believe me). I was lucky enough to catch it, and kept it in my party all the way to the Victory Road. He was fainting to everything in there, so I swapped him for a Claydol. So I may be a bit biased when I think shiny Dustox is pretty rad. [3D='shiny-dustox']
I came across a shiny furfrou and it scared me because it was black and I was like what the heck is wrong with this Pokémon, and then I realized it was a shiny, I deleted my game though, I didn't know you could save your Pokémon with Pokémon bank, I just wanted to play Pokémon X again, I regret my choice every single day lol
