Pokémon Crystal is the remake to the Gold/Silver Versions. The game features Suicune and some of the plot focuses on this legendary Pokémon.

Major Changes
*Pokémon have animations when they appear in battle.
*A Battle Tower has been added
*Players can receive a Dratini with Extremespeed in the
Dragon's Den.
*A move tutor can teach your Pokémon Thunderbolt, Flamethrower, or Ice Beam, which are unavailable as TMs in this game.
*The Ruins of Alph have been changed, with new puzzles the player can solve to read a secret message made by the Unown.

The same Pokémon that can't be obtained in Gold/Silver can't be obtained in Crystal and must be traded from Red/Blue/Yellow. Several other Pokemon also can't be obtained in the game and must be traded from the other versions.
Also, Mew is unobtainable in-game as well. Celebi is unobtainable in the English version of Crystal, but can be obtained in the Japanese version.
