Black & White legendary and event Pokémon — requirements and routes
Every Unova legendary, mythical and event-dependent encounter in the originals, with levels, prerequisites, roamer tactics and form restrictions.
Story and late-game spoilers.
Original Black and White; their sequels have different routes and encounter availability.
Plan ordinary encounters and distribution requirements separately
The paired original games contain nine ordinary legendary species: Cobalion, Terrakion, Virizion, Tornadus, Thundurus, Reshiram, Zekrom, Landorus and Kyurem. One save can encounter seven of them through its own ordinary route, provided the Landorus party requirement is met; the two version counterparts need external acquisition. Victini, Keldeo, Meloetta and Genesect depend on historical distributions or an external compatible trade.
Zorua and Zoroark are event-dependent in the originals’ native acquisition route, but they are breedable ordinary species once obtained. Do not apply the sequels’ gift Zorua, roaming-trio replacements, Therian-form unlock or Black/White Kyurem fusion instructions to these original games.

Cobalion and unlocking the other Swords of Justice
Reach Mistralton Cave by using Surf from Route 6. Bring Strength to move the cave’s boulders; Flash makes its darkness easier to navigate. Climb to the Guidance Chamber, speak with the man explaining the legendary trio, and interact with Cobalion. It is Steel / Fighting and level 42. Encountering Cobalion opens the conditions for Terrakion and Virizion; catching it is not required for their access.
Virizion is in Rumination Field, reached from the interior of Pinwheel Forest, rather than the outer area near Nacrene. It is Grass / Fighting at level 42. Terrakion is in Victory Road’s Trial Chamber, reachable near the upper part of the cave with Strength, and is Rock / Fighting at level 42. Save outside each battle interaction and bring a status plan suited to that target’s type and abilities.



Release and catch Tornadus or Thundurus
After eight badges, the Route 10 gate information mentions unusual Route 7 weather. Return to Route 7, visit the house involved in the storm event, and complete the interaction that releases the version’s roamer. Tornadus belongs to Black and Thundurus to White. Both are level 40 and roam rather than remaining at the Route 7 house. Heavy storm weather identifies the relevant route during the search.
A roamer attempts to flee, so an ordinary slow status user is a poor first plan. A Master Ball removes the escaping problem; otherwise use a durable lead with a suitable trapping ability or a move that acts before escape. Damage and status can persist across roaming encounters. Do not knock it out deliberately when you are trying to retain a particular specimen or nature. Save before releasing it if you intend to restart the generation process.

The story dragon at N’s Castle
Reshiram emerges in Black and Zekrom in White immediately before the final battle with N. The ordinary story sequence requires you to catch your dragon; defeating it or fleeing causes it to be available again there. It has a more accommodating catch rate than many other legends, so a Master Ball is not required. After the catch, the game offers an opportunity to place it in the party for the finale.
There is an unusual storage exception: if both the party and every PC storage slot are full, the story can continue and the uncaught dragon appears at Dragonspiral Tower afterward. A full party alone is not enough for that exception. The normal N’s Castle route is the expected route for a fresh save. Both dragons are shiny locked in these original encounters.
Landorus: the exact party and identity requirement
Reach Abundant Shrine through Route 14 in eastern Unova, using Surf and Waterfall along the way. Put both Tornadus and Thundurus in the party and interact with the shrine. Black requires its Tornadus to have the current player’s Trainer ID; White requires the same of its Thundurus. Catch your own version’s roamer and obtain the counterpart from another game to satisfy that identity check.
Landorus appears at level 70 and is Ground / Flying with Sand Force. A borrowed counterpart can be returned after the encounter. Carry a separate catching member among the remaining party slots and enough supplies for the higher level. Original BW uses Incarnate Forme; Therian forms and the Reveal Glass belong to later software, not this shrine event.

Kyurem and the Giant Chasm snow transformation
After the main story, travel to the Giant Chasm near Lacunosa Town and Route 13. Navigate the outer cave and enter the central forest clearing. Approaching the small central pond triggers the cry and deep snow that changes the clearing into a route toward the inner cave. Follow the newly available snowy path to reach Kyurem, then save before interacting.
Kyurem is level 75, Dragon / Ice, and has Pressure. Bring a catching Pokémon that can survive its attacks; Pressure can make damaging-move PP run out sooner. Exiting the transformed area changes the clearing back, so revisit the pond trigger if the snowy path is gone. Kyurem cannot fuse with Reshiram or Zekrom in original Black and White; the DNA Splicers and fusion forms are sequel mechanics.

Victini and the Liberty Pass
The level-15 Liberty Garden Victini is available only to a save that received the Liberty Pass from the historical event. With the Pass, take the relevant boat from Castelia’s western pier to Liberty Garden, progress through the Team Plasma confrontation and enter the lighthouse basement encounter. Simply reaching Castelia or completing the Pokédex does not place the Pass in the Bag.
The original Liberty Garden encounter is shiny locked. A traded Victini or an old direct-distribution Victini can supply an ownership entry without granting this save its own island event. A fresh save that never received the Pass should record the native catch as externally blocked rather than search for a normal shop or hidden item that gives it.

Zorua and Zoroark: specific movie-event Pokémon
| Target | Required historical Pokémon | Result |
|---|---|---|
| Zorua | Eligible event Celebi moved through the Relocator | Level-10 male gift in Castelia’s GAME FREAK building; leave a party slot and carry a Poké Ball. |
| Zoroark | Eligible shiny event Raikou, Entei or Suicune moved through the Relocator | Level-25 female encounter in Lostlorn Forest, initially disguised as another legendary beast. |
An arbitrary Celebi or an arbitrary shiny legendary beast is not equivalent to the eligible event specimen. Use the Relocator’s intended event transfer before the ordinary post-story Poké Transfer path. The relevant event Pokémon carries an unused activation condition, so a specimen whose event was already consumed may fail to unlock another reward.
Zoroark’s Illusion changes its appearance, not its actual Dark typing. Prepare for the real target even when the screen shows another beast. Once Zorua or Zoroark is obtained, breeding and Zorua’s level-30 evolution can supply the line without replaying the historical event. A compatible local trade for a bred Zorua is consequently a practical separate ownership route.

Keldeo, Meloetta and Genesect: follow-up services
| Pokémon | Where to take it | Reward / restriction |
|---|---|---|
| Keldeo | Moor of Icirrus with Cobalion, Terrakion and Virizion also in the party | Secret Sword move; original BW does not give Keldeo its later Resolute Forme. |
| Meloetta | Castelia café | Relic Song; the move switches Meloetta’s forme during battle. |
| Genesect | P2 Laboratory | Scientist battle; Black gives Burn / Shock Drives and White gives Douse / Chill Drives. |
These interactions teach moves or give held items; none creates the mythical Pokémon. Secret Sword is a special move that uses the target’s Defense in its damage calculation. Relic Song’s Pirouette change is temporary to the battle. A Drive changes Techno Blast’s type rather than making Genesect evolve.
Historical distribution dates and regions matter when identifying an event specimen, but no active ordinary online distribution is promised here. Keep existing Wonder Cards, original Trainer details and transfer history when recording provenance. Consult the local trading and transfer guide before moving a rare Pokémon.
Catch your own version roamer before arranging Landorus, and check whether an event requires a historical item or a specific unused event Pokémon.
