How can I tell in battle if a Pokemon is shiny?

Three things:

• The pokemon will be coloured differently. For some pokemon, this can be a drastic change, while others there can be a very mild difference.

• When the pokemon enters battle, a little sparkling animation will occur, along with a unique sound. Blue stars will come out of the pokemon.

• In the pokemon interface, there will be a red star near the markings to indicate that the pokemon is shiny.

Shiny Pokémon are characterized by not only the different colors, but also the sparkling animation made when is is first sent out or appears. The odds of finding a Shiny Pokémon are next to nothing, but what's harder to find? Shiny Super-Sized Pumpkaboo/Gourgeist with Insomnia. Also, if you completely fill the Pokédex, you will get the Shiny Charm, which increases the odds of finding a Shiny Pokémon.

If a pokemon is shiny, it will sparkle at the beginning of battle, and the pokemon will have a different color than a non-shiny pokemon.

Shiny pokemon have a better chance of appearing in the friend safari. I found about 3 shiny pokemon in the friend safari after encountering about 20 pokemon.
