Gamers will be able to use the DS as a controller to play Pokémon Battle Revolution when it launches in the west later this year.
Nintendo told CVG: "There will be games that take advantage of a connection between DS and Wii. The first game to do this is Pokemon Battle Revolution."
"In Pokemon Battle Revolution, players can port characters from Pokémon Diamond and Pokémon Pearl via the DS and use their Nintendo DS units as controllers," explained Nintendo.
With both the DS and Wii having built-in Wifi capabilities, the two consoles will connect without the need for wires.
Pokémon Battle Revolution is, of course, also the first Wii game to boast online gameplay as we mentioned here last year.
The game will release in the US on June 25. A UK release is yet to be announced.
