A lot! atlease 85 percent of the Pokemon you can catch! Edit: You can catch basically any of the original Kanto Pokémon, plus a few Johto once you get to the Sevii Islands late in the game. These include Pikachu, Bulbasaur, Charizard, Dugtrio, Rhydon, Zapdos, Entei, and about 150 others! Some Pokémon are only in Firered Version, like Arbok and Growlithe, so if you prefer the FireRed-exclusive Pokémon, get FireRed. Leafgreen has version exclusive Pokemon that are pretty good, though.

Crystal is for GameBoy Color, but the others are for GameBoy Advance. The older games weren't meant to interact with the newer.

Staryu are rare in the Pokemon games. To catch one, you must go to Vermilion City and use a super rod in some water. At first, all you'll get is lv. 18-21 Gyrados or lv. 20 krabby, but it's there.
