Pokémon wondertraded to ORAS do not appear in pokédex

pokemon-omega-ruby-alpha-sapphire

I received a few new pokémon over wondertrade, but they did not update to my pokédex.

For example, before the wondertrade, my pokédex seen count was at 23. After receiving new pokémon, the count is still at 23.

Do I have to catch the pokémon myself, or should wondertrade count towards my pokédex?

Best Answer

Wonder-trading pokémon should count towards Pokédex completion. I confirmed this at GameFAQs, where a user asks if they can use Wondertrade to complete their Pokédex.

That said, you do not start the game with a National Pokédex, which is needed to identify all the available pokémon. A Pokédex typically represents a region, and with the amount of pokémon available in the newer generations, a game can include multiple regions. In Omega Ruby and Alpha Sapphire, you start with a Hoenn Pokédex, which only holds a fraction of the pokémon available.

If you capture a pokémon that is not found in the Pokédex you currently have, it will not count towards completion or be otherwise view able until you have acquired a National Pokédex.

To quote the IGN page on the pokédex in Omega Ruby and Alpha Sapphire,

After defeating the Pokemon League, the Pokedex will be upgraded to the National Pokedex (sometimes called National Dex), which lists the Pokemon in the original order from 1 - 719.

... The Hoenn Pokedex features a total of 211 Pokemon.
