I've seen a shiny Charmander and evolutions, I've seen Caterpie and evolutions. I've seen tons of shiny Pokemon, and just out of curiosity, is there a Pokemon that you are unable to find a shiny form of?
Hoopa (not released)
Hoopa Unbound (not released)
Volcanion (not released
If I missed any comment
By hacking you can have any mon shiny even the ones listed above.
Every Pokemon has a shiny form it determines on if it is shiny locked
