I feel like this has come up before, probably in a question someone asked me… yeah, here it is. They’re not something I find terribly interesting in themselves – mostly I figure it’s just a rare recessive gene that happens to be prized by collectors, although it would be interesting to see how communities of wild Pokémon react to the trait. I suspect they do not generally view it positively, or you would expect it to become more common. As far as the games are concerned it doesn’t alter their abilities at all; Ash’s Noctowl was also very small and unusually intelligent even for a Noctowl, but as far as I know no other shiny Pokémon in the anime have exhibited special properties. They don’t really turn up often enough to see any particular patterns in their behaviour or status.
