Pokemon Cloud White Guide
AndReshiram and Zekrom are encountered as part of the story after you defeat the Elite 4 for the first time. As you infiltrate Team Plasma's castle, you'll eventually reach N, who will summon Reshiram in White and Zekrom in Black. In response, your Dark Stone will summon Zekrom if you're playing Pokemon White, or your Light Stone will summon Reshiram if you're playing Pokemon Black. N will give you the chance to capture the Pokemon before fighting you. Both Pokemon come at level 50. You will not be able to proceed with the story until you capture your dragon.

AndAfter you've defeated all the gyms, head back to Route 7 and you'll find the weather to be much stormier than usual. Head to the middle of the route where an old lady will offer you shelter while she explains the story of Tornadus in Pokemon Black or Thundurus in Pokemon White. As you exit the house, you'll see your version's Pokemon fly off. A level 40 Tornadus or Thundurus will now roam randomly around Unova and be available for you to catch. You can see where they may appear by checking the billboards in gate houses. You will also notice the area will become stormy when they are close.
