My first shiny was in Pokémon Silver. I had finished the game long ago and I was getting some berries and apricorns.
It was a a...Rattata. Level 7, a female, and I was riiight there in union cave:
The second one has a funny story: It was in Emerald, I was on my way to Ever Grande City but before to cross the waterfall I wanted to get a Wailord. I was lazy and saw I could catch one instead of training a Wailmer. So I was on route 127 (yeah, yeah, I didn't know I'd never find one there!), on my Linoone's back, fishing on this guy's head, just for fun.
and THERE, a male purple Sharpedo, level 34!
He was named Mr. Triton, he became an awesome Beauty contest winner.
Then I got a shiny Spinda when trying to hatch a huge collection of eggs and to collect ash on the route where ash falls on the grass
The 4th was a she-Pidgey in LeafGreen, level 12, found on route 24. I gave it away to my sister for a service.
The next one was a level 21 male Roselia in Platinum. I don't remember where I was exactly.
Actually I was hoping to steal some lucky eggs from Chanseys, so I used the radar on Route 210 (damn I hate the radar in this game, I can't get it to work for a long row). I planned to give one to my brother for a Pokémon, one for my new Platinum version and one for my SoulSilver. I eventually got them too.
In Pokémon White, after I caught the sages for Looker, I was hoping I could once and for all find something in Route 17's lab.
What I found was a male Frillish, level 10.
My very first Masuda method success (after so many Eevees failures since Gen4) was in Pokémon Y. I just reached the Day Care, so I used the GTS to get first a Ditto, and then all the starters I needed for my Pokédex (that is, not only gen1 and gen6, but each one of them). For this I made babies of my Fennekin and traded them for the two other starters, which made babies too before to be traded again. When I did the same with the Squirtle the Professor gave me, the first baby was a shiny! Unfortunately, like the next one, he was on my first save which was erased by accident, because my Y is on SD card.
The second one in my Y is a level 25 Foongus I found in a horde in Route 20 and it was just here. It's the only one I got while trying to progress in the game's story. I lost it too
And the ninth one was a level 4 female Pidgey on Route 1 in my latest Pokémon Y's game save, I was looking for silly Pokémon to trade in miracle trades so I caught as many Pokémon as possible.
EDIT 1:
In Pokémon Moon, I'm currently breeding Eevees Masuda style, using the hot water to hatch them 18 at the same time while doing other stuffs in game. My first shiney Eevee, a male, just hatched this 7 October'17
