Nintendo is offering Darkrai as a mystery gift through Nintendo Wifi Connection until June 10th in the NA. The Darkrai is lvl. 50, knows Dark Void, and is holding an enigma berry.

I'm not collecting anymore pokemon until a new one is announced for 3DS I spent well over 500hrs just to get all the pokemon on my pearl which I had to play leaf green, Saphire, coliseum, XD Gale of Darkness, and I had to do some trading and then I had to transfer them to Soul Silver (did all of this in one go) and then I got the Black and White ones. No more I'm tired, not until next gen >_<
(feel like crying that's how hard it was)

It's also for the UK as well or NOE.
I haven't done it yet,but I'll do it later.

Grabbed mine last night - it's nice having events over wifi. A lot of places missed out on old event Pokemon just because an event was never set up there.

Whatever happened to the old days where you, well...you know...actually CATCH these guys? I mean, I know you could battle Darkrai in gen 4, but this gen it seems these guys are just handing out all these rare legendaries. I was expecting an epic battle against Arceus! :c

You're suppose to catch Arceus on Diamond and Pearl using the flute.

Yes but Eureka was talking about all the Arceuses they gave away after that, for free.

Really? Had no idea they gave away Arceus.

The freebies are just marketing for The Pokémon Company to advertise new playing cards, dvds, etc. It's very nice to get them for your game, but from the point of view of the company, it's basically free advertising.

That and referring to other legendary giveaways too...the Reshiram/Zekrom...Mewtwo, so on and so forth. I'm sure they could've come up with SOMETHING for past legendaries to battle them in Black and White. I mean, they did it for Hoenn's in HG and SS. xD
(...wait a minute did they do Mewtwo yet? Maybe I have HG's...>.> )

I have no more room for anymore pokemon in my PC box.
I have all the rattata I need.
