>>32947228Shiny Kingler in Pokemon Silver. I was a dumb little kid, so I didn't save before red gyarados.
Since then, I've gotten a shit ton of shiny mons. RNGed a ton back in Gen 4 and 5, but even barring that, still way more encounters than the average dude, I'd imagine. Off the top of my head from wild encounters / random eggs, I've found Beedrill, tentacool, whismer, zubat, Gengar (full blown gengar from old chateua ev training), oddish, Tauros x2, Roselia, Zebstrika, Litwick...
I'm about to cap out at 999:59 on SuMo and the shinies have been pretty plentiful too. There's a bit too much from Gen 6-7 to list out.
