Rayquaza is a typePokémon introduced in Generation III. It is also known as the 'Sky High Pokémon' and is also a member of the weather trio along with Groudon and Kyogre.

How to Obtain
Go to Cinnabar Volcano and talk to the guy with red wings in the house at the very back. He will have a feeling that Route _____/ _____ City will have a rare Pokémon. That Pokémon can be Rayquaza, Cresselia or Manaphy.

It can also be obtained from trading and the Pokemon Roulette. However, it is highly unlikely that wish_z will ever make a Rayquaza code because it will break the game.

Evolution
Rayquaza can Mega Evolve into Mega Rayquaza. In Project: Pokemon however, Rayquaza won't have Mega Evolution implemented, as it may break the game.

Moves when caught
May vary depending on level found and can also be taught by Move-Relearner
