How to Get the Legendaries in Pokemon Black
POKEMON BLACK AND WHITE LEGENDARIES AND SPECIAL POKEMON
Legendary Pokemon
| #643 - Reshiram and #644 - Zekrom | |
  | Reshiram 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. |
| #638 - Cobalion | |
 | Cobalion can be found in the top floor of the Mistralton Cave, known as the Guidance Chamber. You will need Surf to access the cave, then Strength and Flash to navigate through. Cobalion is at level 42. |
| #639 - Terrakion | |
 | Terrakion is in the Trial Chamber of Victory Road, which is close to the exit to the Pokemon League. From the top floor cave entrance, head down the left flight of stairs and enter the cave to the left. You must have defeated or captured Cobalion first, otherwise there will be a stone in the way. Terrakion is at level 42. |
| #640 - Virizion | |
 | Virizion is in the Rumination Field of Pinwheel Forest. From the concrete bridge, head right and navigate your way as far east as you can. Cross to another clearing by going through a hollow log and enter the Rumination Field to find a level 42 Virizion. You must have defeated or captured Cobalion first, otherwise a row of stones will block your way. Virizion comes at level 42. |
| #646 - Kyurem | |
 | Kyurem can be found in the Giant Chasm at the north end of Route 13. As you enter the cave, head right then up and use Strength on the boulder there. Continue west and head down the stairs to the crater area. Make your way to the lake in the center of the crater and a sudden blizzard will fill the area with snow. Head to the north-east corner of the crater and enter the cave, and you'll see a level 75 Kyurem waiting for you. |
| #641 - Tornadus and #642 - Thundurus | |
  | After 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 by. |
| #645 - Landorus | |
 | Landorus can be found in the Abundant Shrine on Route 14 by Black City or White Forest, depending on your version. You must have caught Tornadus or Thundurus from your version and also have the other traded over from your version counterpart. Examine the shrine at the north-west corner of the field and a level 70 Landorus will attack. |
Event Pokemon
| #494 - Victini | |
 | Victini can be found on Liberty Garden, which requires a Liberty Pass to get to. When you have received this Key Item from a Nintendo Event, head to Castelia City's westernmost pier and talk to the ferryman. When you arrive, circle around the outside of the island to gain access to the entrance to the lighthouse. You'll be fighting a few Plasma Grunts along the way. Check out the basement, where a level 15 Victini will be waiting for you. |
