Pokémon Black and White-themed Happy Meals are due to arrive at McDonald's outlets across North America from June 15th.
Running until July 5th, the promotion will see 12 Pokémon trading card game cards - each with a special McDonald's M foil stamp - available to be collected.
The Happy Meal will also include one of six Pokémon figures, including Pikachu and five Unova region Pokémon: Axew, Dewott, Pignite, Servine and Woobat.
The promotion will continue in international markets later in 2012.
"Last year's Pokémon Happy Meal promotion was a huge hit, and we're certain Pokémon fans will love what's in store this summer," said JC Smith, director of consumer marketing for the Pokémon Company International. "It's been fun partnering with McDonald's to once again provide something special to our fans."
The promotion will be supported by McDonald's with TV advertising, in-store POP and online activities.
