Five Legendary Pokémon are at your disposal in Pokémon Crystal: Lugia, Ho-Oh, Raikou, Entei and Suicune. Each has a powerful hidden ability that Pokemon of the same kind caught in Ultraspace will never have.
Zapdos is in the Rock Tunnel, easy to find from either entrance, just walk straight through with Repells.
Find a route where to enter and exit the route with nearby grass. (Ecruteak City is a good place to start as there is grass nearby on the south side of this city). Take about 20 steps in the grass with the Repell. If no Pokémon appear, Raikou or Entei aren’t there, leave the area and come back.
Five Legendary Pokémon are available to you in Pokémon Crystal: Lugia, Ho-Oh, Raikou, Entei, and Suicune.
The legendary birds in these games have different catching methods than those in the other two games. Both are found after the Elite Four at level 60.
You can get Lugia and Ho-oh in both Pokemon Gold and Pokemon Silver, but what you get first will depend on which game you have. In Pokemon Crystal, Ho-Oh appears only after the three legendary beasts Suicune, Raikou, and Entei are captured.
It’s a complete Pokémon Crystal remake of the GameBoy Color classic. The story is the same as the original Crystal, with a ton of additional events and even a brand new region to explore.
You must trade to get Charmander in the following games: Gold. Silver. Crystal.
According to the catch rate calculator on Dragonflycave, a paralyzed Lugia with 1 HP has a 2.3% chance of being caught by an Ultraball.
There are four islands here, but the one in the northeast is what you want for Lugia. In the first cave exit via the ladder at the top right. This will bring you to a ridge at the east end of a large cave. Follow this ridge south and go down the ladder.
