The coolest Pokémon of all, in their rarest, most sought-after form. Woah.
As you might know, mega stones can transform Pokemon into more neater, more elaborate versions of themselves. There are 48 megas in the new Pokémon games. Shiny Pokémon, meanwhile, are special Pokémon that come in unique colors. There is only very slim chance you'll find a shiny Pokémon out in the wild. While you might never see a shiny mega Pokémon in your own game you can still take a look at what mega shiny Pokémon in Omega Ruby and Alpha Sapphire look like in action thanks to this video by MaxEzzy:
I'm partial to shiny Primal Kyogre, as well as shiny Primal Groudon. They look like total badasses thanks to the black colors. Do you have any favorites?
