Gold and Silver's Pokedex covers 251 Pokemon across the Johto and Kanto regions. Gen 2 split the old Special stat into Sp. Atk and Sp. Def, added Dark and Steel types to counter Psychic, and introduced breeding and held items. The time-of-day system means some Pokemon only appear at night or during the morning. Use the filters to browse by type, generation, or stats.

251. That's 100 new Johto Pokemon added to the original 151 from Kanto. The game spans two regions, so you encounter Pokemon from both generations during the story. Some Gen 1 Pokemon only appear in Kanto after beating the Elite Four.
Cyndaquil is the safest pick. Typhlosion has good Speed and Sp. Atk, and Fire coverage is hard to find early. Totodile hits hard physically but suffers from the Gen 2 issue: Water is a special type, so its Attack stat doesn't apply to STAB moves. Chikorita is the weakest start by far, since Grass is resisted by most early gyms.
Generation 2, released in 1999 in Japan and 2000 in North America for the Game Boy Color. Added breeding, held items, a day/night cycle, two new types (Dark and Steel), and split the Special stat into Sp. Atk and Sp. Def.
Yes. After beating the Johto Elite Four, the entire Kanto region opens up with 8 more gym leaders to challenge. It's the same map from Red and Blue, updated for Gen 2. Clearing all 16 badges unlocks the fight against Red on Mt. Silver.
