In the original Pac-Man (released in October 1980 as an arcade game in Japan), the ghosts, also known as the "Ghost Gang," each had unique AI traits that contributed to the game's enduring appeal.

The objective of the game is to eat all of the dots placed in the maze while avoiding four colored ghosts - Blinky (red), Pinky (pink), Inky (cyan), and Clyde (orange)—who pursue Pac-Man.
