Last year, The Pokémon Company gave away a special Mewtwo for a limited time over Wi-Fi to Pokémon Black/White owners in Japan. Now, that giveaway event is headed to North America.
Starting February 12th, The Pokémon Company will begin distributing Mewtwo over Wi-Fi for Black/White owners. The giveaway page specifies that the special Mewtwo will come with a move that he can’t normally learn, so it does seem like this is the same as the Japanese giveaway, where Mewtwo came with Psystrike, Shadow Ball, Aura Sphere, and Electro Ball.
In the Japanese giveaway, Mewtwo was at level 70 and carried a King’s Rock, which gives you a higher chance of making the opponent flinch.
