The Ghost Monsters

Blinky, Pinky, Inky and Clyde, collectively known as the Ghosts or Ghost Monsters, are the main antagonists from the  video game series. In the original arcade game and most of their appearances since, their objective is to chase Pac-Man around the maze and stop him from eating all the dots, though they become vulnerable to being "chomped" by him if he eats a Power Pellet. Each one of them behaves differently: Blinky, the red ghost and leader, always follows Pac-Man; Pinky, the pink ghost, typically tries to ambush Pac-Man from the front; Inky, the blue ghost, tends to unpredictably switch between the two strategies; and Clyde, the orange ghost, will sometimes follow Pac-Man but typically wanders off whenever he gets close.

In the Hanna-Barbera animated series based on the games, the ghosts were naturally featured as recurring antagonists, appearing as the henchmen of a higher ghost villain named Mezmeron (an idea that would appear with new villains in later Pac-Man games). For some reason, Clyde was made the leader of the group instead of Blinky. The quartet were also joined by Sue, a female ghost who originated as a counterpart to Clyde in the  game, but made into a completely different character for the cartoon.

Two decades later, in the newer animated series , the Ghosts again appeared as the henchmen of a new villain, in this case Lord Betrayus. Unlike previous iterations, though, the Ghostly Adventures versions of the Ghosts are more good-natured and even supply the teenaged Pac-Man with information about Betrayus' schemes.
