Pac-Man

Pac-Man (PROSE: The Arcade of Doom) was a video game starring a circular yellow character with black dots for eyes and a triangular mouth.

The character and the game were invented at some point after 1972. The Twelfth Doctor told Maxwell Collins that he still had the game to look forward to. (COMIC: Moving In)

The character was depicted in front of 2 orange circles in graffiti on a wall in Cardiff in the 2000s. (TV: Everything Changes)
