Which three Pokémon form the original starter trio in Pokémon Red and Blue?

The original Pokémon Red and Blue starter trio is Bulbasaur, Charmander, and Squirtle.

At Professor Oak’s laboratory, players choose one of these three Pokémon to begin their journey. Bulbasaur is Grass/Poison, Charmander is Fire, and Squirtle is Water. Their types create a simple triangle: Grass has an advantage over Water, Water over Fire, and Fire over Grass.

The rival chooses the starter with a type advantage over the player’s selection, while the remaining Pokémon stays with Professor Oak. This opening choice became one of the defining traditions of the main Pokémon role-playing games.

The trio is sometimes confused with starters from later generations, such as Chikorita, Cyndaquil, and Totodile from Johto. Pikachu became the anime’s most famous starter-like partner, but it is not one of the three standard choices in Red and Blue.
