Probably my very first one, which was a shiny shuppet in alpha sapphire before I even knew what a shiny was, but I saw the sparkles and I caught it (I still have it)

Randomly finding a shiny Slurpuff with no shiny charm or boosts.

And the shiny Nickit hunt went well, got a square shiny

Honestly, the shiny Gigalith I have in Pokemon GO.

Random Numel in Alpha Sapphire. It was the first shiny i had ever encountered and holds a special place in my heart

Probably my Shiny Gastrodon, as it was the first shiny I ever caught. I also really like my shiny Drifblim and Shiny Gallade though.

I was distracted while shiny hunting dreepy and i was holding forward when i ran into it. I freaked out.

There was also a marked shiny gible i got too

In Pokémon violet, I’ve had many shiny encounters that were amazing, but my favorite was Azurill. It was on the day of the release of Pokémon scarlet and violet and I was like 20 minutes into the game and I don’t remember if I had a sandwich or not… anyway, I just remember yelling “shiny!!”

My favorite Shiny encounter was probably my Shiny Pheromosa from Sword & Shield

I got it from Dynamax Adventures (Crown Tundra DLC)

And the funny thing about dynamax adventures is that the Pokemon won't show up as shiny until you've caught it and finished the dynamax adventure

So it was absolutely crazy when I was looking through the Pokemon I'd caught and Shiny

Pheromosa just popped up

Probably the shiny buneary I got in Legends Arceus on release
