Huh. Wal-Mart has exclusive Pokemon included in copies of Pokemon X and Y. What's curious is that they aren't anything too special -- X comes with Garchomp, while Y includes Scizor. These two have Mega Evolutions (and are admittedly badass), but it's not as if either one is challenging to obtain through online trading. Weird!
A quick Google search indicates that the Garchomp has either Sand Veil or Rough Skin and the moves Slash, Dragon Claw, Dig, and Crunch. It'll also be holding a Dragon Fang. Scizor, on the other hand, will have Swarm or Technician, no item, and the moves X-Scissor, Night Slash, Double Hit, and Iron Head. Both Pokemon come in a Cherish Ball.
I'm excited for a proper distribution event, whatever that may be.
