Speaking of which, there should be a BW Kyurem thread in Ubers :o
So yeah, with the information that we've gotten so far, I think it's pretty safe to say that these two sexy new things will be Ubers. About time too, since Kyurem always got the bad end of the deal, IMO.

Black Kyurem (BK):
125 HP / 170 Atk / 100 Def / 120 SpA / 90 SpD / 95 Spe
Notable moves: OUTRAGE, Fusion Bolt, Dragon Claw, Substitute, Roost, Ice Beam, Draco Meteor, Freeze Shock o_0
Strongest Outrage in the game, and you'd think people should be reasonably happy with that. However, its lack of movepool kind of annoyed the crap out of everyone, especially lack of physical Ice STAB. However, this thing is still an excellent wallbreaker. It cleanly 2HKOs the bulkiest of Groudon with Choice Band Outrage, does >45% to Ferrothorn, while taking out Lugia with Fusion Bolt. To top it off, BK can easily run a mixed set with Ice Beam to take out annoying Ground-types almost immediately.

White Kyurem (WK):
125 HP / 120 Atk / 90 Def / 170 SpA / 100 SpD / 95 Spe
Notable moves: DRACO METEOR, ICE BEAM, Fusion Flare, Focus Blast, Earth Power, Roost, Substitute, Dragon Pulse, Blizzard
This, I think, has got to be the most mindless Pokemon I have ever seen. Like I have said on IRC, as long as Kyurem-W is not facing an imminent outspeed and OHKO from the opponent, you can just click Draco Meteor, and you will never lose unless it misses. Draco Meteor coming from Base 170 SpA is just simply mind-boggling in its power, capable of OHKOing Kyogre, 2HKOing Heatran and doing 41-48% to Blissey, even, if you're holding Specs. I have never seen a Pokemon so spammable.
Discuss their potential play in Ubers!
