There are 151 Master Trainers total, and each of these trainers will focus on a specific species of Pokémon, such as Squirtle. By defeating them, you can get individual titles, such as ‘Master Trainer of Squirtle’. “Doing this 151 times is certainly a challenge”, said Masuda.
Pokémon: Let’s Go, Pikachu! and Eevee! will come to the Nintendo Switch on November 16, 2018.
