Celebi is a Mythical Pokémon, and its availability is typically limited to special events or promotional distributions.
Here's why:
* It's not part of the main Ruby game: Ruby's Pokedex doesn't include Celebi.
* "Destiny Reign of Legends" is a fan-made hack: It is not an official Pokémon game.
If you're looking for a Pokémon game where you can encounter Celebi, you would need to look at games like:
* Pokémon Colosseum and XD: Gale of Darkness: Celebi can be found in these games after completing certain tasks.
* Pokémon Mystery Dungeon: Some games in the Mystery Dungeon series feature Celebi.
* Pokémon GO: You can occasionally encounter Celebi in events or during special periods in the mobile game.
* Pokémon Let's Go Pikachu/Eevee and Sword/Shield: While not caught traditionally, you can obtain Celebi through certain events or as a reward.
Remember to check official Pokémon websites or news sources for the latest information on how to encounter Celebi in any game.
