(UPDATED: Includes Ghostly Adventures 3DS Final Boss)
Here's a compilation I made of all the final boss battles in Pac-Man games. This video doesn't start until Pac-Man 2: The New Adventures from 1994 rather than the first Pac-Man in 1980, since Pac-Man games never really had bosses until this game. No one has really made a final bosses video for Pac-Man except for the Pac-Man World games, so I decided to give it a shot.
