Which Pokémon games first supported Nintendo Wi-Fi Connection?

Pokémon Diamond and Pearl were the first Pokémon games to support Nintendo Wi-Fi Connection. Released for Nintendo DS, they allowed players to trade and battle online through the service.

The games introduced the Global Trade Station, which let players offer Pokémon and search for requested species across the world. They also supported online communication features, including voice chat, although the service itself has since been discontinued.

Earlier Pokémon games supported local connections and link cables, but those methods required players and hardware to be nearby. Diamond and Pearl expanded the idea of Pokémon exchange by connecting players through Nintendo’s online network.

Diamond and Pearl were released in Japan on September 28, 2006, and formed Generation IV. They added 107 new Pokémon and introduced the Sinnoh region, while retaining the series’ longstanding need to trade between versions to complete the Pokédex.
