Porygondolier found a wild shiny Pokémon in an original copy of Pokémon Red

Shiny Pokémon were introduced in Gen 2 in terms of Pokémon being a different colour variation based on their stats (known as DVs or Determinant Values, now IVs or Individual Values) but those values were present in Gen 1 so you could technically get shiny Pokémon in Red/Blue/Yellow. However, this was reserved to static Pokémon so you couldn’t find a shiny Pidgey on Route 1. There was a theorised exception though and that theory has now been proved by Porygondolier in the above video. I highly recommend that you read the video’s description as it details everything clearly but the crux of it involves the Silph Scope and how it acts almost like a “shiny charm” in the Pokémon Tower. Where rerolls for DVs aren’t applicable in general wild Pokémon, in the Tower, the Silph Scope allows for that (it causes the wild Pokemon’s DVs to be rerolled once, increasing the shiny odds from 0, to approximately 1/8192). And after 5,979 encounters, a wild shiny Gastly appeared! No glitches, no mods, no…
