>>43333682I got a Shiny Pikachu on Yellow, Tangela on Red (as in once it's put on a Gen 2 game it becomes a Shiny due to the DVs or whatever adding up), Shiny Ponyta on Gold, Shiny Yanma and Zubat on Crystal (and if hatching counts I've also gotten a Shiny Cyndaquil, Larvitar, Miltank and Charmander), nothing in Gens 3 or 4, Shiny Sandile and Sigilyph in White, Charmander, Fennekin, Clauncher, Ralts, Klefki, Skrelp and Goomy in Y, Mimikyu in Moon, Riolu in Ultra Sun and a bunch in Let's Go because it's Let's Go.
Pic related is my favourite though. I found a Shiny Zigzagoon in Ruby which, discounting Gold's Gyarados, was the first one that I found, but due to my only Pokemon in my party being underlevelled or overlevelled I couldn't damage it enough to catch it. To boot, I only had a Great Ball and 2 Poke Balls on me, neither of which worked.
After 10 years though (weird coincidence) I beat the league in Y and the first Pokemon I encountered was this, I love this fucker.
