The 'Hello, Peter' meme originated from the first trailer for the 2021 film Spider-Man: No Way Home, featuring the return of Alfred Molina as Doctor Octopus. The scene, which depicts Doc Ock emerging from smoke on a bridge to greet a confused Peter Parker, instantly went viral due to the nostalgic impact of the Spider-Man 2 villain joining the MCU. Fans quickly began using the template to represent unexpected encounters, the return of something from the past, or simply to parody the dramatic delivery of the line. It serves as a versatile tool for expressing recognition, surprise, or an inevitable confrontation.
