Nintendo Power Pikachu Info.
Ball: Cherish Ball
Event Moves: Wish, Present, Volt Tackle, Surf
Held Item: Light Ball
The "NZone" Pikachu you mentioned is the following:
1. Not the 20th Anneversary Nintendo Power Pikachu
2. An Official Nintendo Event
3. Knowing only Present
Now take in to consideration, if it is a NZone Pikachu, which according to Nintendo.com itself is "This test service offers game previews (movies and demos), game exclusive content and special playable content from more than 15 titles!"
Try to explain how you'd get NPower Pikachu, which has its own Wondercard and message that comes with it that specifically talks about Nintendo Power and says NOTHING WHATSOEVER about Nintendo Zone.
Because that's impossible.
