* Rikou: Rikou is a character from the Pokemon Diamond, Pearl, and Platinum games. He is not present in Pokemon Crystal.
* Entei: While Entei is a legendary Pokemon, it is not available in the original Pokemon Crystal. It's possible to obtain Entei through events or special distributions, but it's not part of the regular gameplay.
Here's how you can obtain Legendary Pokemon in Pokemon Crystal:
* Raikou, Entei, and Suicune: These Pokemon are obtainable by using a special event code in Pokemon Crystal. This code was distributed in Japan and is no longer valid.
* Lugia and Ho-Oh: These Legendary Pokemon are the main focus of Pokemon Crystal's story. You'll encounter them during the game's plot.
If you are playing Pokemon Crystal, you can obtain Raikou, Entei, and Suicune through trading with other players who may have obtained them via special events in the past.
