The Surprised Pikachu was first seen in the hit anime series Pokémon in Season 1, Episode 10, “Bulbasaur and the Hidden Village”. The screenshot shows the electric Pokémon with an open mouth and wide eyes, as though it were surprised at something.
The reaction image was first used in 2018, but has since made it’s rounds on the internet. The image is usually paired with captions where a set-up leads to a predictable outcome that nevertheless leaves one surprised. When do you like to use the Surprised Pikachu meme? Let me know in the comments!
