Some Pokémon can be met only once in the whole adventure: you are given them, you trade for them, or they wait for you at a specific spot. Missing them often means having to trade with a friend. Here is the complete list.
⭐The must-haves
Two starter Pokémon
Chespin, Fennekin or Froakie in Aquacorde Town, then Bulbasaur, Charmander or Squirtle, given by Professor Sycamore in Lumiose City along with its Mega Stone.
