Eternal Darkness
Eternal Evil
I'd really like Ash to get a shiny Gigalith (eventually) but I just can't see it happening.
I just can't see any precedence where a shiny version of a Pokemon debuted before it's normal coloration.
Plus with the new Pokedex feature in Black and White game versions, we won't be able to tell if Roggenrola is shiny or not, since in Black and White, if you see a shiny of a Pokemon first, you only have the Pokedex art of the shiny version.
Unlike past generations where the normal coloration showed up in the Pokedex even when it was shiny.
Didn't Noctowl debut the same episode as its non-shiny form?
